== Nominal vs. real GDP ==

Recommending a "'''nominal''' GDP per capita" to be used in adjusting large capital expenditures (incl. government) seems like a folly to me: wouldn't a "'''real''' GDP per capita" be a much more relevant measure to adjust for inflation? "Per capita" portion of the measure is a useful adjustment when using GDP to compare large-scale expenditures, as it normalizes for the size of the economy in question. But using [[nominal GDP]] instead of [[real GDP]] seems to defeat the very purpose of trying to adjust the value of money for effects of inflation.

In fact, I would argue that using the [[GDP deflator]] by itself in order to adjust the value of money would achieve the right effect in this case – as it is a direct adjustment for the value of money that uses GDP-based calculations instead of CPI-based ones. (It also implicitly takes care of the "per capita" part, as it compares prices rather than volume of expenditures comprising GDP – hence no need for an extra adjustment.)

So my proposal is: whenever the distinction between consumer-relevant prices and large-scale capital expenditures is warranted, we should use CPI adjustment in the former case, and the [[GDP deflator]] adjustment in the latter.

:In returning to the issue and researching it in greater depth, I'm fully in agreement with you.  In fact, I think we screwed up badly here, and I'm sorry for having played a role in the screw-up.  CPI (or RPI in the UK) and the GDP deflator are the only two standard measures for measuring what is known as "inflation".  I think we should remove the GDPPC datasets from this template, as they are not suitable for measuring infation.
:We will need to add datasets for GDP deflators.  It looks like they can be derived from tables output by https://www.measuringworth.com/usgdp/ and https://www.measuringworth.com/ukgdp/ .  Any volunteers?--[[User:Father Goose|Father Goose]] ([[User talk:Father Goose|talk]]) 07:44, 29 December 2017 (UTC)
::To be fair I am not an economist so I don't have an instant response to this thread. My understanding is that they are useful more measuring different things but I need to read up on what the distinction is. Do we have any economists on here who are able to put it into layman's terms for us with a soild example? It may well be the case that the index is being used both correctly and incorrectly in our articles, so we probably can't just delete one series and replace it with another. [[User:Betty Logan|Betty Logan]] ([[User talk:Betty Logan|talk]]) 01:19, 30 December 2017 (UTC)

:::I am not an economist, so I might not completely understand it. Seems to me that some things don't scale the same way. Building interstate freeways doesn't scale the same as population, for example. But also government spending scales in ways that don't directly follow personal cost of living. But also, it isn't obvious that all capital (and government) expenses should scale the same way, so there might need to be more indices. But two is probably as much as we can keep track of. [[User:Gah4|Gah4]] ([[User talk:Gah4|talk]]) 02:40, 30 December 2017 (UTC)

::::As ever, it comes back to what you are trying to communicate or analyse (see http://www.tandfonline.com/doi/abs/10.2753/CHA0577-5132490407 for an economics article on the problem, elements of which are reproduced [https://www.measuringworth.com/explaining_measures_of_worth.php here]). To take an example like the Empire State Building (built at a cost of $40,948,900 in 1931), when you compare that figure to 2016, what do you most want to know? You could compare it using a CPI measure (essentially converting $40m into the cost of 1931 household goods like beer and bread, then reconverting out into the cost of household goods like TVs and cars in 2016 - $645 million); you could compare it using a GDP measure (asking what % of the US economy $40m represented in 1931, and then asking what the same % of the US economy would be in 2016 if you spent it on a new project - $9,850 million); you could compare it with a GDP per capita measure (asking what % of the US economy $40m represented in 1931, allowing for the rather larger US population in 2016 than in 1931, and then doing the same calculation - $3,790 million); you could do it by comparing wages ($1,920 million or so, depending on whose wages you are interested in); etc. etc.

::::I agree with Father Goose that when measuring inflation, particularly in government, a GDP deflator (i.e. real rather than nominal) would often be used - it's very often the right tool for that problem, particularly if you're trying to calculate a rate of inflation, or trying to predict future costs. But there are plenty of exceptions in research terms - there's an interesting US government article on the problem from a medical perspective [https://bea.gov/papers/pdf/Adjusting-for-inflationDunnZuvekasGrosse.pdf here] with a summary on p.15. It lays out some of the questions you might be asking as a researcher and how you might answer them: Calculating the share of economy-wide expenditures devoted to health care over time? Use nominal costs and don't deflate. Comparing the social value of interventions across health and non-health sectors? Use a general price index. Comparing the amount of societal resources expended in different periods? Use a GDP price deflator, etc. The writers (unhelpfully for our perspective) conclude that "there is no single gold standard for adjusting health expenditures for inflation".

::::In short, there are a range of choices available to academics and writers depending on what they're trying to analyse... I think it gets really difficult on the Wiki, as it is a complex subject, and many editors don't even read the guidance on the front of this template, let alone delve into further details. And don't get me started on the medieval and early modern comparison problems... :) I'd support trying to provide several options for editors, fleshing out the guidance a bit more, including where to look for reliable source off-wiki, including on particular topics.

:::::My main point (and the one fully understood it seems and shared by {{u|Father Goose}}) is the difference between nominal and real. Of course the nominals are important for certain research – in particular, ''when you want to derive the relevant deflators and price-index series''. But when we need to calculate money-equivalence across time (which in effect, what "reals" do for us), we are not facing the choice of "real vs. nominal": the answer is clear here, we have use the reals; but rather we are facing the choice of which one of the "reals" we need to use (i.e. which of the adjustment methods is most relevant to the case in question). So nothing you wrote above, {{u|hchc2009}}, contradicts this, but it seems you may have been addressing a different question when talking about a sometimes-importance of nominals.

::I defer to the expertise you guys are showing in here, that's way outside my wheelhouse. Mostly I just correct or add to articles about big construction projects, since bricks and steel and heavy machinery follow such different trajectories than bread and clothing and medicine. I assume NGDPPC is meaningful for something, or it wouldn't exist, but if the "US-CAP" and "UK-CAP" aliases I wanted were switched to a more useful measure, it wouldn't affect me at all. The various specific measures can be left in a separate table at the bottom, to people who **really** want to get into the weeds, like the medical issues Hchc2009 poses. <small>[[User:SilverbackNet|SilverbackNet]] <sup>[[User talk:SilverbackNet|talk]]</sup></small> 21:16, 30 December 2017 (UTC)

:::NGDPPC is meaningful, but as one way of measuring growth, not of inflation.  As such, it does not belong in a conversion template named "inflation".  The addition of it to this template was outright erroneous.  The GDP deflator was what what should have been added, and used, as our means of adjusting large-scale expenditures.  As to {{u|Hchc2009}}'s comments on what adjustment to use for health care costs, the paper he cites discusses the shortcomings of using PCE, CPI, or the GDP deflator for various scenarios – but they are all superior to using NGDPPC, which is not a measure of inflation ''at all'', and is not mentioned in the paper he cites.
:::I've added a UK GDP deflator index to the template.  I'll add the US one later.  I'll wait for a few more days of comments before changing the documentation to advise using the GDP deflator for non-consumer expenditures and deprecate the use of NGDPPC.--[[User:Father Goose|Father Goose]] ([[User talk:Father Goose|talk]]) 01:32, 6 January 2018 (UTC)

===Remove the NGDPPC indexes===
So now for the real work.  Can anyone cite a source suggesting that any form of GDP per capita measure is appropriate to use for inflation adjustments?  I'm not talking about "measuring wealth", a concept without a fixed definition.  I'm talking about just [[inflation]], a concept generally understood to mean changes in prices in a national economy.

There are a few different standard ways to measure inflation (i.e., [[price index]]es): 
*The Consumer Price Index in the US
*The Retail Price Index in the UK
*The GDP deflator (which we now have in the template for the US and UK)
*The [[producer price index]]
*The [[personal consumption expenditures price index]]
*[[Chained CPI]]
*The [[Harmonised Index of Consumer Prices]]

Of these, only the first three are typically used to "adjust for inflation" in generic contexts.  The other indexes are used by economists to perform analyses, to measure subsectors of the economy, or by central banks to perform specialized adjustments.  Nowhere in my research have I come across using any form of GDP per capita measure as an adjustment for inflation.  ([https://www.investopedia.com/terms/p/per-capita-gdp.asp Investopedia] suggests it's useful for measuring changing standards of living, which is not the same concept as inflation.)

Given that, I think it's time to say that using NGDPPC in our inflation-adjusting template is outright incorrect, and it should be removed.  The GDP deflator should be emphasized as the index to use for non-consumer expenditures.  To minimize disruption, the NGDPPC option can be marked as deprecated until such time as all in-article uses of it have been removed; then the index itself should be removed from our template.--[[User:Father Goose|Father Goose]] ([[User talk:Father Goose|talk]]) 17:16, 12 January 2018 (UTC)

:Yes, "per capita" GDP is meaningless in the context we discuss here – i.e. measuring inflation. I think instead of presuming that editors actually wanted to use NGDPPC when adding the relevant snippets of template invocation to the Wiki pages, we should just assume that what was meant is a capital-expenditure inflation measure (as NGDPPC was indeed erroneously documented as a way to do this in the template doc). So we can safely replace NGDPPC with the new GDP deflator measure. [[User:Cherkash|cherkash]] ([[User talk:Cherkash|talk]]) 01:55, 13 January 2018 (UTC)

:::::I think I used to believe that the per capita GDP made sense for something that a country only needed one of.  When I see a large cost, I can consider my fraction of the cost. Say a national capitol building, which a country only needs one of. Since the US population is about 1/3 of a billion, it isn't so hard to convert a price to price per capita in my head. That might also work for state capitol buildings, as the number of states is growing slowly. For rent or housing costs, where it is normally one per person, there is no reason to scale with population.  For railway stations and shopping malls, the number needed should scale a little less than linear with population. I suspect that one could, other than [[WP:OR]], figure out the [[scaling law|scaling]] constants. [[User:Gah4|Gah4]] ([[User talk:Gah4|talk]]) 02:02, 16 January 2018 (UTC)

::::::It doesn't scale with population, though.  It scales with economic growth (GDP).  It scales ''inversely'' with population, as "per capita" is the divisor.  Even if a nation is richer over time, that doesn't necessarily mean that a capitol building will be (or should be) more lavish, or even larger.  Or even that something like military expenses should be presumed to grow with GDP, per capita or not.  That's dependent on government revenues (taxes) but also on spending priorities ([[peace dividend]], etc.).
::::::It's a bit unfortunate that the ''Measuring Worth'' website is our most convenient source for inflation datasets.  I trust the data they provide, but the site itself has as its focus a set of thought experiments that are readily misunderstood about how exactly growth, and in particular inflation, should be calculated.  The "different ways of measuring worth" are not wrong, but are best left as an academic exercise.  Anything we refer to as "inflation" on Wikipedia should be based on a standard [[price index]] only.--[[User:Father Goose|Father Goose]] ([[User talk:Father Goose|talk]]) 19:04, 21 January 2018 (UTC)

'''Replying to the first comment by {{User4|Cherkash}}, suggesting a replacement of "nominal GDP per capita" for "real GDP per capita":'''<br>
Actually an adjustment by "real GDP per capita" would only take into account the economic growth while ignoring any price change (inflation) during the given period of time, which would be futile and useless for any comparison. The so-called NGDPPC indexes using "nominal GDP per capita" are intended to demostrate the impact of both inflation and the enrichment of a society when comparing prices, that is, that an ammount of money that would appear as a fortune in 1900, like $5 dollars, by today's prices it will only be $123-147 dollars (whether using GDP deflator or the Consumer Price Index, respectively), which is not a lot of money, but if we use the 'nominal GDP per capita' it would be equivalent to $1,060 dollars nowadays, so this index was conceptualized to see how affordable was certain good in the past (people are typically much poorer in the past than in the present), making it not a good tool for prices comparison, but rather an expensiveness index.[[Special:Contributions/179.53.111.218|179.53.111.218]] ([[User talk:179.53.111.218|talk]]) 04:05, 15 February 2018 (UTC)
:Thankyou for your input 179.53.111.218. This goes some way to answering my question at the top. Let me just recap (for my own benefit mainly), and you can correct me if I am wrong: CPI is as we all know the price index of a "basket of goods" while the GDP deflator is a "price index for the entire economy". Both are designed to track inflation. Nominal GDP is an index for the total value of the economy, while Real GDP is an index of economic growth (essentially the nominal GDP minus the inflation). Nominal GPD per capita is basically an index of average "wealth", whereas Real GDP per capita is basically a measure of "productivity". Would these be accurate descriptions in layman terms? I am still trying to get my head around the different distinctions. [[User:Betty Logan|Betty Logan]] ([[User talk:Betty Logan|talk]]) 06:18, 15 February 2018 (UTC)
::You may be confusing "wealth" and "income", {{u|Betty Logan}} (e.g. when saying "Nominal GPD per capita is basically an index of average "wealth"": wealth is the sum total of accumulated resources, whereas GDP, or rather some portion of it which is not consumed and is saved/transformed instead, is more closely related to the ''change'' in wealth).
::Same objection, to a degree, applies to you, {{u|179.53.111.218}}: you somehow assume that GDP per capita translates into wealth (either directly, or by being its rate of growth). Whereas in reality, the personal income as a percentage of GDP – and taking it even further, the percentage of that income that is a disposable income (in one sense or another) – may vary drastically across time. So such comparisons using GDP itself, without taking care to derive equivalences that are more relevant to the subject of "feeling rich/poor" are ill-advised. [[User:Cherkash|cherkash]] ([[User talk:Cherkash|talk]]) 23:15, 15 February 2018 (UTC)

:::Yeah.  I have yet to see anyone who defends the use of NGDPPC indexes actually provide a rationale for using them rooted in any kind of established economic practice.  Mostly it seems to boil down to defending their use because they produce numbers in line with expectations, but never actually explaining what the meaning is, numerically, of adjustments using NGDPPC.  Calling it "wealth" (or "worth") is no explanation at all.  It is a reasonable-sounding but ultimately arbitrary claim.

:::Worse still, making adjustments like this to match expectations hides the actual economic changes that have occurred across different eras.  A person getting $5 in 1900 could buy approximately the same amount of goods for $123 now.  They could not buy $1,060 worth of goods.  Meanwhile, a modern person receiving $1,060 could buy $43 worth of 1900-era goods, not $5.  What this means is that the modern man is indeed 8 times richer (on average) than his great-great-grandfather.  (The underlying cause of this is because productivity has outstripped inflation.)  But this does not mean my great-great-grandfather received $1,060 worth of wealth.  I am wealthier than he was.  He really did receive a mere 123 bucks.  We cannot magically say he got $1,060 simply because that's about the amount I would get today for the same amount of work.  And it would be even less meaningful to say that if he sold something for $5, it would be worth $1,060 today.

:::NGDPPC reflects that wealth has grown over time, which is ''exactly why you cannot use it'' to map wealth from an earlier era onto the wealth of the modern era: doing so obscures the fact that wealth has grown over time, and it obscures the fact that people are richer in the modern era, in terms of the goods they can afford, than they were in past eras.--[[User:Father Goose|Father Goose]] ([[User talk:Father Goose|talk]]) 04:42, 18 February 2018 (UTC)
::::The definition at [https://www.measuringworth.com/calculators/uscompare/index.php Measuring Worth] states: "''The GDP per capita is an index of the economy's average output per person and is closely correlated with the average income. It can be useful in comparing different incomes over time.''" The source is [https://www.measuringworth.com/sam/ Samuel H. Williamson], a professor of economics. Again, this is not my background so I don't dispute that GDP per capita is not useful for not inflating the "cost" of something, but it seems to have some valid applications in comparing value over time. You are most likely correct that the series does not belong under an inflation template, but I am not sure it should be just deleted.  For instance, if I want to know who was "richer", John D. Rockefeller or Bill Gates, there are two ways to consider that question: i) what would their respective fortunes be worth today (which would use a GDF deflator); and ii) what is their comparative "richness" by the standards of their own eras? In this case GDP per capita seems like a useful metric because wealth has outstripped inflation so you need more than just a price index to draw a comparison. [[User:Betty Logan|Betty Logan]] ([[User talk:Betty Logan|talk]]) 11:26, 18 February 2018 (UTC)

:::::You can use NGDPPC to compare average incomes across different eras, but as I argued earlier, not to meaningfully ''adjust'' them.  So... ''maybe'' you could use the NGDPPC dataset within a template to note that what someone made in 1900 is about an eighth what a modern person might make.  But using straight NGDPPC assumes [[income distribution]] is equal and also doesn't take into account [[cost of living]] changes.  So using it in pretty much any kind of numeric manner (or template) is iffy.  I think we're better off just sticking to inflation adjustments and letting people be occasionally surprised when historical figures don't seem all that big, because they weren't.

:::::As for Gates vs. Rockefeller, we already do compare them on Wikipedia using the GDP deflator: see [[List of wealthiest historical figures]] and [[List of richest Americans in history]].  If one wanted to compare their fortunes relative to their eras, you could express them as a percentage of GDP, and we do that in [[John D. Rockefeller]]: "a fortune worth nearly 2% of the national economy".  (I have a problem with this approach, as it compares assets to production, two very different values, but it is a common approach nonetheless.)  None of this involves NGDPPC either way.

There is an RfC at [[Talk:Manchester Martyrs#Request for comment: use of "Inflation" template|Talk:Manchester Martyrs]] regarding the use of this template in a case where there is a very wide range of possible current values of a sum of money.

Now resolved. The gist of the discussion was that, for a reward of £300 offered in 1867, the [[CPI]] – the value of a basket of goods – is not a good measure of its worth in 2016, and that, instead of the template, there ought to be an expression of its value in terms of average annual wages at the time (in this case, £300 ≈ seven years wages), still citing [https://www.measuringworth.com/datasets/ukearncpi/ MeasuringWorth]. I wonder if it would be worth adding a note to [[Template:Inflation/doc]], drawing attention to the fact that there are cases where ''neither'' this template nor the US-GDP or UK-GDP indexes should be used?

== UK - CPI / CPIH ==

Some discussion on Twitter about this template's use of RPI.  Per the [[Office for National Statistics]]: "The course on which ONS has embarked has therefore been ... discouraging the use of RPI, while recognising the legacy needs ...

::I believe the editor is referring to unholy messes like the one that can be seen at [[List_of_highest-grossing_films_in_the_United_States_and_Canada#Not_adjusted_for_inflation]]. This has happened across dozens of articles, simply because we have entered 2019. The exact same thing happened last year. Two things need to be done to fix the errors. First of all [[Template:Inflation/US/dataset]] needs to be updated with the 2018 index (found using the link given in the template documentation); I fixed this myself last year but the template has now been protected meaning I cannot do this. After this is done the year at [[Template:Inflation/year]] needs to be updated to 2018.

With this:

<code>| 2018 = 754.6</code>

<code>| 2019 |#default = 768.3 </code>

This is just the annual update for the template. The new information comes from https://www.minneapolisfed.org/about-us/monetary-policy/inflation-calculator/consumer-price-index-1800-

'''Step 2'''

Once the dataset has been updated the source also need to be updated. At {{tl|Inflation/fn}}, in the <code>| US = </code> line please update the date to January 1, 2020. There are two instances of the date that need to be updated, representing the two date formats.

'''Step 3'''

The final step updates the most recent year. At {{tl|Inflation/year}} you need to replace this line:

<code>| US|USD   = 2018</code>

with this:

<code>| US|USD   = 2019</code>

If you complete the updates successfully then the errors that can be found at aticles such as [[List of highest-grossing films in the United States and Canada]] should disappear. Best wishes. [[User:Betty Logan|Betty Logan]] ([[User talk:Betty Logan|talk]]) 11:20, 1 January 2020 (UTC)

'''Step 1'''

At {{tl|Inflation/UK/dataset}} please replace this:

<code>
|       2018|#default    =       125.939
</code>

needs changing to 

<code>

</code><code>
|       2019|#default    =       129.159
</code>

'''Step 2'''

Once the dataset has been updated the source also need to be updated. At {{tl|Inflation/fn}}, in the <code>| UK = </code> line please update the date to February 2, 2020. There are two instances of the date that need to be updated, representing the two date formats.

'''Step 3'''

<code>| UK|GBP   = 2018</code>

with this:

<code>| UK|GBP   = 2019</code>

== This should be a module to reduce expansion depth ==

See also: [[Template talk:US$#This needs a rewrite to reduce template expansion depth]].

This template uses over 20 of the 40 levels of "expansion depth" allowed by MediaWiki software described at [[:meta:Help:Expansion depth]].  Pages that go over the limit wind up in [[:Category:Pages where expansion depth is exceeded]].

At least one template, {{tl|US$}}, uses 33 of the 40 levels when it is used with the {{para|year}} parameter to calculate inflation, which doesn't leave much headroom for templates that call US$.

One good solution would be to turn this template into a module. Anyone up for the task? [[User:davidwr|davidwr]]/<small><small>([[User_talk:davidwr|talk]])/([[Special:Contributions/Davidwr|contribs]])</small></small> 22:52, 13 February 2020 (UTC)

Hello<br>
I found this template by accident while trying to fix a sourced current value for a 19th century cash amount. It is certainly a useful template; can I suggest you add a link to it, so that readers might know where the estimate comes from, and that editors won't otherwise spend time tracking the information down/trying to fix it per RS/VERIFY? In the meantime I’ve done [https://en.wikipedia.org/enwiki/w/index.php?title=The_Adventure_of_the_Six_Napoleons&diff=prev&oldid=962242808 this] to provide some verification.

Is there any way of prompting the use of all three templates?

== Bug report.   Template math is off by $100 ==

Using this template for $25 and $50 respectively (and all other values being the same) yields:

$25 {{Inflation|US|25|1897|fmt=eq|r=-2}}

$50 {{Inflation|US|50|1897|fmt=eq|r=-2}}

Since 2 x $25 = $50, one would naturally assume that doubling the amount in the $25 template to $50 would produce a template output of $1,600 yet what we are seeing is instead $1,500, off by $100 or approximately 7%. --[[User:That man from Nantucket|That man from Nantucket]] ([[User talk:That man from Nantucket|talk]]) 08:59, 1 May 2020 (UTC)

: {{ping|That man from Nantucket}} You have used the parameter <code>|r=-2</code> asking it to round to the nearest $100.  If you change the rounding parameter you will see a different precision, such as:

== Can the index know the currency symbol? ==
I used this template for British pounds and it surprised me that I have to put the currency symbol if I'm not using US dollars. Doesn't the <code>GBP</code> index know which currency (and therefore symbol) it's expecting as input, and therefore producing as output? I thought it might do automatic currency conversion so that I could specify <code>cursign=$</code> and have the resulting GBP converted to USD but it's just to change what's displayed.

Anyway, it would be nice if I could just do <code>\{\{Inflation|GBP|1.5|2000|2019|fmt=eq}}</code> and have it work as expected. [[User:Akeosnhaoe|Akeosnhaoe]] ([[User talk:Akeosnhaoe|talk]]) 20:36, 1 August 2020 (UTC)

== Default <code>r=-3</code> to prevent false precision? ==

Too often I find {{tl|inflation}} abused in a way that reports numbers with [[false precision]], [[Special:Diff/948574871|like here]]: "... signed him to a contract worth $15,000 ([[United States dollar|USD]], ${{formatnum:{{Inflation|US|15,000|2007|r=1}}}} today)." Even ignoring the fact that here $15,000 is probably rounded already, the implied precision (down to cents!) of the adjusted number is clearly absurd. Since this is a [[Special:Diff/947984987|frequent]] [[Special:Diff/914155807|occurrence]], I suggest we change the default precision of this template accordingly. --[[User:Bender235|bender235]] ([[User talk:Bender235|talk]]) 20:16, 1 April 2020 (UTC)
:
:Making the default r=-3 doesn't help much, except for baseball salaries.  Recent discussion in {{tl|convert}} shows that there is a better way to do this.  {{tl|Convert}} does it based on significant digits, or relative precision. Setting r=-3 would be wrong for values of a few dollars, or a few billion dollars.  In addition (since there are many r= out there), there should be a sigfig= option, default without r=, for relative digits.  In the case of {{tl|convert}}, it figures out the digits based on the input value.  That might or might not be right here. [[User:Gah4|Gah4]] ([[User talk:Gah4|talk]]) 21:08, 16 July 2020 (UTC)

== Add to sources discussion ==

Hiya to add to the sources discussion above, I have been happily using this template, it's super useful (for example at [[List of heists in the United Kingdom]]) so thanks to all the creators for their hard work!! Recently, someone added a reference for the figures [https://en.wikipedia.org/enwiki/w/index.php?title=Ann_Smith_(activist)&diff=968955664&oldid=967936816 here] which doesn't give the same info as the template (1,120,000 vs 1,526,611.85) and today there's [https://en.wikipedia.org/enwiki/w/index.php?title=Hilda_Gregg&diff=971237944&oldid=971170270 this citation needed] tag added. So I came here to ask if the template should be referenced. I suppose best practice says yes,and if that is the case should it then be added automatically? I'll be adding {{tl|inflation-fn}} from now on, including those pages I've mentioned, cheers! [[User:Mujinga|Mujinga]] ([[User talk:Mujinga|talk]]) 11:02, 5 August 2020 (UTC)

:1684 is a long time ago, and a lot has changed since then. According to the accuracy link on that page, the goods that households buy have changed over the years.  OK, for one, 1,526,611.85 has way too much precision, and even 1,120,000 probably still does. The difference is a factor of about 1.4, which is probably about as good as you can get without knowing the exact set of goods.  As I understand, the price of a BigMac is used by some as an index, (I suspect not for this one), but obviously that doesn't work for 1684. You just have to believe that a factor of 1.4 is close enough. [[User:Gah4|Gah4]] ([[User talk:Gah4|talk]]) 22:16, 5 August 2020 (UTC)

== Units addition ==

Would it be possible to allow units to be entered in the value, which would be copied to the output? Most of the numbers I deal with are of the form "1.2 billion", which has to be manually recreated using two templates.

== "Calculation error" NaN on [[Maung Weik]] ==

I happened to look at the error category and see the article [[Maung Weik]].

The full message is ''<nowiki>Error when using {{Inflation}}: NaN/calculation error please notify Template talk:Inflation.</nowiki>''.

I see that the issue was introduced to that article with what is currently the most recent edit, [[Special:Diff/960240485]], which reveals that that this template is actually being called from {{tl|US$}}, so the above discussion [[Template talk:Inflation/Archive 2#This should be a module to reduce expansion depth]] might be relevant.

{{edit template-protected|Template:Inflation/US/dataset|answered=yes}}

1. [[Template:Inflation/US/dataset]] requires a change from

to
:<code><nowiki>| 2019 = 768.3</nowiki></code>
:<code><nowiki>| 2020 |#default = 777.7</nowiki></code>

2. [[Template:Inflation/year]] requires a change from
:<code><nowiki>| US|USD   = 2019</nowiki></code>
to
:<code><nowiki>| US|USD   = 2020</nowiki></code>

3. [[Template:Inflation/fn]] requires the current date be updated in two places on the line that starts with <code><nowiki>| US = </nowiki></code>.

::::::Using the method you used above for 1700: <code>(130/100) * 27</code> (I'm assuming the 100 is from 1800 column 6 in McCusker, and 1860=27 is from minneapolisfed) equals <code>35.1</code> instead of <code>43.9072</code> ("my" method: <code>130/(151/51) [or 130*(51/151)] = 43.90728476821192</code> [1700=130 and 1800=151 from McCusker, 1800=51 from minneapolisfed]).

:::::::The reason for the discrepancy there is that McCusker's numbers from 1800-1860 are different than the Fed's numbers in that time period, so the relationship between 1800 and the 1860 number is different for each source and therefore calculating the 1700 number would be different based off the 1800 numbers (which you used) instead of the 1860 numbers (which I used). In McCusker the <code>1800 number / 1860 number = 1.51</code>, while for the fed it's <code>1.89</code>. Therefore the <code>Fed number/McCuscker number</code> should be greater at the 1800 number than the 1860 number. The equation I used in a different form is <code>130 * (27/100)</code>(with 27 being the fed number and 100 McCusker's number); the difference between our methods is because <code>51/151>27/100</code> , 51/151 being the 1800 relationship and 27/100 being the 1860 relationship.
:::::::The question then becomes should we use the 1800 numbers or the 1860 numbers uniformly. I suppose we should use the 1800 numbers simply because that's what I used for the 1700-1799 index and because it reduces a sharp drop off of numbers, but I would think theoretically each method is equally valid. 
:::::::The reason I originally calculated it differently was because the data I used did not have data for 1700, only 1699, and it seemed simplest just to compare the 1699 number with the 1860 base. Ultimately that was an arbitrary decision which I thought wouldn't matter as theoretically the CPI from 1800-1860 should be the same using either the Fed source or McCuscker. <span style="font-family:DrukarniaPolska"><span style="background:#f70202">[[User:Zoozaz1|<b style="color: #fffb00">Zoozaz1</b>]] [[User talk:Zoozaz1|<b style="color: #fffb00">talk</b>]]</span></span> 03:51, 4 July 2021 (UTC)

== Calculated currency figures should be shown with limited precision Suggestion ==

I'm writing this after noticing the following output of the Inflation template, in the article Margaret Brown: 

"[Brown] also received a $700 monthly allowance (equivalent to $20,163 in 2020) to continue her travels and social work."

The problem here is that $20,163 is being reported to 5 significant digits, far beyond the precision of the calculation.

Inflation calculations are always approximate, because many very varied price histories are combined to obtain a useful average. In this case the starting figure is $700 in 1909. That probably represents only 2 significant digits. Then the amount reported should be rounded to the nearest $100, for a result in this case of $20,200 in 2020.

My point, then, is that the Inflation template should only report 2 or possibly 3 digits of precision. [[User:Dratman|Dratman]] ([[User talk:Dratman|talk]]) 23:05, 28 September 2021 (UTC)
:
:There is the r= parameter to indicate rounding. The value is the number if digits after the decimal point, default of 0. The units conversion {{tl|convert}} does, more or less, figure out the significant figures of the input and propagate it. In your case, r=-3 might be about right.

::Keep in mind, that the inflation values are updated, so I wouldn't recommend rounding to less than 2 digits - especially when the number is small enough to easily loose precision after some time (ex. 10,000 can drop to 9,000).

== Formatting ==

It seems that when using non-named parameters (numbered arguments) for the index and amount, the template is whitespace sensitive (it shouldn't be? Update: or at least, other templates seem to handle it; I got a bit lost reading [https://meta.wikimedia.org/wiki/Help:Template this] and [https://meta.wikimedia.org/wiki/Help:Newlines_and_spaces this]). It's could be underlying Lua code, but I can't tell from here. e.g. <code><nowiki>{{inflation|NZ|100000| start_year=1970 | fmt=eq | r=-4}}</nowiki></code> works, but not <code><nowiki>{{inflation | NZ | 100000 | start_year=1970 | fmt=eq | r=-4}}</nowiki></code> (note the spaces around the NZ and 100000). Respectively: "{{inflation|NZ|100000| start_year=1970 | fmt=eq | r=-4}}" and "{{inflation | NZ | 100000 | start_year=1970 | fmt=eq | r=-4}}". — [[User:Jonathanischoice|Jon]] ([[User talk:Jonathanischoice|talk]]) 23:33, 22 May 2022 (UTC)
:@[[User:Jonathanischoice|Jonathanischoice]] The mediawiki software strips whitespace from named parameters (such as {{para|index| NZ }}), but not positional ones like in your example above.

:{{u|SpikeToronto}}, there are two options that come to mind. You can add Euros to this template separately and use that, or you can look through the templates of EU countries here to see if any of those are converted to Euros at some point (which I suspect some are) and use that when dealing with Euros.

I am going to document my work process here, in case I am doing it wrong.

There is no conversion factor in this template for euros! So I will make one.

As far as I can tell, it would be pretty simple: create [[Template:Inflation/EU]] and then create [[Template:Inflation/EU/dataset]] to populate it.

My buddy who knows quite a lot about economics tells me that you can get CSV tables from FRED that document CPI inflation for euros here: https://fred.stlouisfed.org/graph/fredgraph.csv?bgcolor=%23e1e9f0&chart_type=line&drp=0&fo=open%20sans&graph_bgcolor=%23ffffff&height=450&mode=fred&recession_bars=off&txtcolor=%23444444&ts=12&tts=12&width=1168&nt=0&thu=0&trc=0&show_legend=yes&show_axis_titles=yes&show_tooltip=yes&id=CPHPTT01EZM659N&scale=left&cosd=1997-01-01&coed=2022-09-01&line_color=%234572a7&link_values=false&line_style=solid&mark_type=none&mw=3&lw=2&ost=-99999&oet=99999&mma=0&fml=a&fq=Monthly&fam=avg&fgst=lin&fgsnd=2020-02-01&line_index=1&transformation=lin&vintage_date=2022-12-14&revision_date=2022-12-14&nd=1997-01-01

:Eurostat may be more appropriate and "official" source: https://ec.europa.eu/eurostat/web/hicp/data/database
:Euro area inflation will be different from European Union as a whole, as not all countries use Euro, so please keep it in mind and document appropriately.

== What actually happens when I do this? ==

Let's say we have 50,000 francs in the year 1830 -- I want to know what is going on when I type the following.
:<nowiki>({{formatprice|{{inflation|FR|50000|1830|r=0}}}} in {{inflation/year|FR}})</nowiki>
Francs were converted to Euros at 1 euro for 6.55957 FRF on 31 December 1998 -- is it giving Euros in 2022, or francs in 1998? Or something else? '''[[User:JPxG|jp]]'''×'''[[User talk:JPxG|g]]''' 10:55, 14 December 2022 (UTC)

:{{U|JPxG}}, reading the data source (with the title of "Conversion coefficient of the euro or franc of one year, into euro or franc of another year"), I suspect it is currency agnostic; in others words, entering pre-conversion francs and converting that to 2022 would give you the value in francs adjusted for inflation; entering post-conversion euros and converting that to 2022 would give euros adjusted for French (not European) inflation.

==Small, old calculation==
I'm trying to show an equivalent amount for a pre-decimal penny from 1830, and showing the equation <nowiki>{{Inflation|UK|{{Pounds, shillings, and pence|d=1}}|1830|fmt=eq|cursign=£}}</nowiki> gives "{{Inflation|UK|{{Pounds, shillings, and pence|d=1}}|1830|fmt=eq|cursign=£}}", which isn't much of a help!

==Final period==

==Non-footnoted footnotes==

Is there an equivalent of this without the ref tags? If I'm putting the {{tl|inflation}} info itself in a footnote, I don't want another footnote linked to from within that, I just want the whole lot inline. Does that make sense? [[User:Pseudomonas|Pseudomonas]]<sub>([[User talk:Pseudomonas|talk]])</sub> 09:58, 17 October 2009 (UTC)

:This would really be a helpful feature. Perhaps a "noref" parameter could be added to suppress the generation of the ref tags, or even better, the template could be split, with {{tl|Inflation-fn}} generating the ref tags, and calling upon {{tl|Inflation-src}} to generate the contents. That way, we could call {{tl|Inflation-src}} from within a footnote. —[[User:Mjb|mjb]] ([[User talk:Mjb|talk]]) 22:09, 9 April 2011 (UTC)

== Dates ==

The current template produces a footnote of "Federal Reserve Bank of Minneapolis. Retrieved '''December 7, 2010'''" Is there any way of producing one that could produce one as "Federal Reserve Bank of Minneapolis. Retrieved '''7 December 2010'''"? (Or is there a version that does that already?) I've had comments from reviewers of articles who want to see all the dates in the same format if possible.

== Support for more use scenarios ==

This template really needs support for more use scenarios, such as shortened footnotes and nested footnotes. The current use case pretty much only works for the scenario where you have the full citation inline in the article text.

To do this there are two variables that need to be controllable: whether the output is wrapped in <code>ref</code>-tags, and whether and what {{para|ref}} parameter is passed to the underlying citation template. There also needs to be consistency on whether the output is a citation or an explanatory note. Compare:

*<nowiki>{{inflation-fn|UK}}: </nowiki>{{inflation-fn|UK}}
*<nowiki>{{inflation-fn|US}}: </nowiki>{{inflation-fn|US}}

{{reflist-talk}}

(there is also some weird extra HTML wrapped around the US output for some reason).

I would propose something along the lines of moving most of the logic and citation data into a Lua module (handling logic in template syntax is… challenging), with the citation data in configuration tables, and turning the template into a thin wrapper. The output could then vary based on {{tlx|inflation-fn|US|mode{{=}}shortened}} (short author—date ref, linked to same ID generated by {{para|mode|full}}), {{tlx|inflation-fn|US|mode{{=}}full}} (full cite without <code>ref</code> tags, generates same ID as {{para|mode|shortened}}), {{tlx|inflation-fn|US|mode{{=}}inline}} (default, what it does today), and maybe {{tlx|inflation-fn|US|mode{{=}}nested}} (if that is still necessary).

The cost and downsides would be having to write the Lua module in the first place, having to maintain the citation data there (instead of the template), and maintaining a more complex system.

== Canada's inflation ==

Please update Canada's inflation to 2017. The new value of 130.4 from [http://www.statcan.gc.ca/tables-tableaux/sum-som/l01/cst01/econ46a-eng.htm Statscan] is already inputted. Thank you. Keith 11:04, 22 April 2018 (UTC)  <!-- Template:Unsigned --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Keith o|Keith o]] ([[User talk:Keith o#top|talk]] • [[Special:Contributions/Keith o|contribs]]) </small> <!--Autosigned by SineBot-->

== "Must be done every time" admonishments ==

The docs for several of the template parameters claim {{tq|This must been done each time the template is called in an article, or there will be an error message in the reference list.}} Aside from the grammatical issues ("been" instead of "be", at a minimum), that claim doesn't appear to be '''accurate'''. Observe:
{{Block indent|1=<nowiki/>
===Last author ampersands===
To promote consistency with an article that uses {{para|last-author-amp}} to join the last author in a list with an ampersand, footnotes that list multiple authors and the {{tl|cite web}} base template can also use this parameter. This must been done each time the template is called in an article, or there will be an error message in the reference list.
*{{tlx|Inflation/fn|US-GDP|3=last-author-amp=yes}} = {{Inflation/fn|US-GDP|last-author-amp=yes}}
*{{tlx|Inflation/fn|US-GDP}} = {{Inflation/fn|US-GDP}}
{{reflist|}} }}

If I'm interpreting it correctly, the quoted admonishment is implying that the second call above would cause an error, by not repeating the {{para|last-author-amp|yes}} parameter. But in reality, it doesn't seem to cause any problem at all. Should we just remove the "This must been done each time the template is called in an article, or there will be an error message in the reference list." admonishment from the various documentation sections where ti appears? Or is it still accurate for some parameters other than {{para|last-author-amp}}? -- [[User:FeRD NYC|FeRD_NYC]] ([[User talk:FeRD NYC|talk]]) 14:03, 9 August 2018 (UTC)
:{{re|FeRD NYC}} Not sure why you're not seeing the error messages, but this template generates code like <code><nowiki><ref name="inflation-US">…</ref></nowiki></code> which ''will'' generate an error message if two ref tags with the same name have different content (date format, last auth amp, etc.). See [[H:CERDK]]. If you use a web inspector type tool you'll see that your example above contains the following:
::<code lang=html"><nowiki>
<span class="error mw-ext-cite-error" lang="en" dir="ltr"><span class="brokenref">Cite error: <span class="brokenref">Invalid <code>&lt;ref&gt;</code> tag; name "inflation-USGDP" defined multiple times with different content (see the <a href="/enwiki/wiki/Help:Cite_errors/Cite_error_references_duplicate_key" title="Help:Cite errors/Cite error references duplicate key">help page</a>).</span></span>
</span>
</nowiki></code>

:: {{Syntaxhighlight|lang=css|code=span.brokenref { display: none } }}
:: Seems a bit strange. Especially as ''other'' reference errors are still displayed. Regardless, as you say the conflicting reference content does indeed cause errors, so I'll leave the admonishment in place and simply tweak the grammar.

This page shows the format as Inflation/year where the format shown on [[Template: Inflation]] shows it to be Inflation-year in its examples. I just tried this in the [[Great Chicago Fire]] article, and it works with Inflation-year, not using the slash character /. Is the separator character irrelevant? I did not try it with the / as I am spending my time on millions to billions reading correctly.

== duplicate reference definitions ==
{{Tracked|T205803}}
This template appears to create duplicate reference definitions. For example, the "filming" section of [[Dr. No (film)]] invokes this template twice, and ends up with duplicate definitions of a reference named "inflation-UK". How can these errors be corrected? It seems like the template should create identical reference text for each invocation, but it apparently does not do so. How can multiple invocations of the template safely be used on the same page, without causing duplicate reference errors? -- [[User:Mikeblas|Mikeblas]] ([[User talk:Mikeblas|talk]]) 14:13, 29 September 2018 (UTC)

::: Hey Mike, I fixed the [[Dr. No (film)]] so you can see what I did.

:::::{{Re|CV9933}} I don't know what has changed to cause these errors.

:::::{{Re|Trappist the monk}} Could you have a look at [[User:John of Reading/X3]] please?

::::::{{Re|John of Reading}}I don’t think anything is broken as such - it is just a consequence of defining a CS1 ref name and then trying to use it twice or more in the same article. The fix I implemented is pretty much the same as what we have been doing for the last three years. If we were to remove the name= parameter from the cite web template, I suspect we wouldn’t have a duplicate ref problem in the article, but we would see the same ref appear in the ref list twice. Because of the transclusion to many articles I wouldn't fancy playing with the template to find out. [[User:CV9933|CV9933]] ([[User talk:CV9933|talk]]) 14:08, 30 September 2018 (UTC)
::::{{Re|CV9933}} Your fix works, but I don't think it's the right thing to do. Lots of articles invoke the {{tl|inflation-fn}} template multiple times. It's clear those articles were encoded expecting that the template would do the right thing: generate a reference the first time, and re-use that same reference on any subsequent invocations. This [[2010 FIFA World Cup|World Cup]] article uses six invocations of the template. It worked fine for a couple years, but over the last couple of days something was changed that makes the article produce duplicate ref-def errors for all but the first invocation of the {{tl|inflation-fn}} template. I don't think we can apply your explicit ref-tag fix to every invocation in every article that uses it. -- [[User:Mikeblas|Mikeblas]] ([[User talk:Mikeblas|talk]]) 14:36, 30 September 2018 (UTC)
{{ec}} Yeah, something is broken.  I assert that it is MediaWiki's handling of TemplateStyles.  There are no restrictions on what may be made part of a reference.  Any template that uses TemplateStyles may be used within a reference so the problem is not confined to the cs1|2 templates; cs1|2, being the most common templates used in references, just happen to reveal the problem.  MediaWiki handles template styles by insertion of a stripmarker where the template includes the <code><nowiki><templatestyles src="Module:Citation/CS1/styles.css" /></nowiki></code>; for cs1|2 at the tale end of the rendering.  After cs1|2 has done its thing and after MediaWiki has discovered and flagged the duplicate-ref-different-text errors, then, MediaWiki replaces the stripmarker with the value of the stripmarker (I don't know exactly what that is; css file name? content of the css file?).

Stripmarkers are unique, even when they point to the same thing, because templates are processed in isolation from each other so that processing knows nothing about what has come before.  Here are the code-view renderings of two identical {{tlx|cite web}} templates; stripmarkers are at the tail ends:
:<code><nowiki>{{cite web |title=Title |url=//example.com}}</nowiki></code> → {{cite web |title=Title |url=//example.com}}
::{{code|{{cite web |title=Title |url=//example.com}}}}
::{{code|{{cite web |title=Title |url=//example.com}}}}
I can do nothing to fix this so you-all should report it at phabricator.

:Thanks, {{Re|Trappist the monk}}. I guess I'm having a hard time understanding what recently changed. If it's WikiMedia itself, I don't understand why so few references are affected. Because Wiki syntax is complicated and cofusing (especially when we consider citation templates, and all the rules for using them, and ...) users really struggle to get pages to work well -- and be correctly referenced. There are lots of pages which have duplicate references explicitly in text, but they're no problem. And only a few (three?) template-generated references are causing problems, too.

::On 29 September 2018 I updated the cs1|2 module suite.  Before that time cs1|2 had not been using TemplateStyles.  Now that cs1|2 is using TemplateStyles this MediaWiki flaw is revealed.

This template though uses the <code><nowiki>{{#tag:ref}}</nowiki></code>  magic word.  Apparently, handling of that is different from how the {{tag|ref|params=name="duplicate name"}} tag is handled.

== Template-protected edit request on 3 February 2021 -- a wikilink to [[MeasuringWorth]] is possible ==

{{edit template-protected|Template:Inflation/fn|answered=yes}}
I've created an article about the MeasuringWorth website, and we could link to it in footnotes that use that site.  A replacement of "work = MeasuringWorth" by "work = [[MeasuringWorth]]" in this template might do the trick.  Since people won't click through to it very often, perhaps it's not worth the trouble.  Sometimes pages have so much wikicode that they exhaust the Wikipedia back end.  I trust your decision on this, templateers.  -- [[User:Econterms|econterms]] <small>([[User talk:Econterms|talk]])</small> 23:16, 3 February 2021 (UTC)
