 * , entirely up to you if you want to do this, but since you're updating Russian inflation statistics and are a Russian speaker, if you have the time it would be quite helpful if you could add the data in this document, which I can't read, to the template if it provides anything useful (it also seems more reliable than the current National Economy of Russia source).

 * Absolutely, will look into that. Szmenderowiecki (talk) 15:48, 4 March 2024 (UTC)
 * Here I found a downloadable and better searchable version of this paper, but even though the scope of work is admirable, each of the components is assessed separately (so prices on grains, clothing, metals, salt etc.). There is no one CPI measure in this work, and calculating it ourselves will definitely be verboten.
 * Also, this work only covers the XVI century. There's a lot of economic literature listed here that may be useful for the XVII century but I will have to read it when I have time. Szmenderowiecki (talk) 17:14, 4 March 2024 (UTC)

Update requested for US 2023 data
Template is not yet showing US data adjusted to 2023. See the examples on Template:Inflation/doc that are like which are still rendering as "in 2022" rather than "in 2023". I see that Template:Inflation/US/dataset has been updated with 2023 data, but I think that also Template:Inflation/year still needs to be updated for 2023? Thanks. netjeff (talk) 19:30, 10 March 2024 (UTC)
 * made two edits in responding to this edit request: one to Template:Inflation/US/dataset to add the 2023 figure (per edit req) and one to Template:Inflation/fn to Update US access-date. A comment on Template:Inflation/US/dataset says:
 * – wbm1058 (talk) 14:08, 29 March 2024 (UTC)
 * Clearly leaves something to be desired, as we have issues with drive-by template editors responding to edit requests here.
 * shows that there are two US inflation datasets:
 * Inflation/USD, which redirects to Inflation/US, Inflation/US/dataset, Inflation/US/startyear
 * Inflation/US-CAP, which redirects to Inflation/US-GDP, Inflation/US-GDP/dataset, Inflation/US-GDP/startyear
 * edited Template:Inflation/year @ 02:13, 28 March 2024, to Update US cap on behalf of User:SWinxy (note the hidden comment next to the edit here).
 * But SWinxy edited Inflation/US/dataset, not Inflation/US-GDP/dataset. We need to be clear on what the difference is between these, and make sure that we're updating the correct one. – wbm1058 (talk) 15:19, 29 March 2024 (UTC)
 * Asking for updates in multiple places (especially with something as complicated as this) is always going to cause issues, no matter how strong the hidden comment warning. Could we design it so that e.g. Inflation/year automatically reads the other templates and derives the most recent year from them?  Sdkb  talk 15:25, 29 March 2024 (UTC)
 * Aw, shoot. Sorry for messing this up. While I erroneously missed editing Inflation/year, the edit request was to Inflation/US/dataset. Does Inflation/US-GDP/dataset need to be updated as well? SWinxy (talk) 17:52, 29 March 2024 (UTC)
 * OK, getting myself up to speed. The source for Inflation/US/dataset is the Federal Reserve Bank of Minneapolis, and right, that's what you got in the previous edit request.
 * The source for Inflation/US-GDP/dataset is Samuel Willamson's MeasuringWorth website, per the template documentation. That was last updated by at 07:15, 30 November 2023, and I see that Titan877 was responsible for a couple of 30 November 2023 edit requests above, which were done by Paine Ellsworth. Those updated the year from 2021 → 2022, and came from http://www.measuringworth.com/datasets/usgdp/
 * On that page, you use the form in the grey box on the upper right of the page. Check the box for "US GDP Deflator", enter initial year 1790, ending year 2023, then click, and...
 * Voila, we have a number for the year 2023,  – so, yes, we can update that from 2022 → 2023 now. Apparently that was done months late, last year, since it wasn't done until the end of November. – wbm1058 (talk) 19:20, 29 March 2024 (UTC)

Suggestion: Use a more up-to-date inflation metric
The United States has two common inflation metrics: the CPI and the PCEPI (Personal Consumption Expenditure PI). The CPI and its variants are designed for cost-of-living adjustments to wages in negotiated contracts. As a result, the CPI excludes many common goods (such as health insurance) provided as fringe benefits rather than being paid for out-of-pocket. The PCEPI gives a more complete picture by including all consumption goods and services. The CPI is also methodologically awkward in that it uses a right-chained basket (right-hand sum) to approximate inflation, which is strictly less accurate than the PCEPI's use of the trapezoid rule. (The bad approximation has stuck with us for what are essentially political reasons.)

The PCEPI is the metric recommended by the Federal Reserve, and the metric it pays attention to when it decides monetary policy; as a result, I suggest replacing CPI with PCEPI in this template. Does this sound reasonable? –Sincerely, A Lime 18:25, 15 May 2024 (UTC)


 * , yes, though I would perhaps suggest adding another template rather than replacing the current one, for two reasons. Firstly, I assume CPI data goes back further and might be necessary for obtaining data from certain years, secondly there may be cases where one methodology is more appropriate than the other. Zoozaz1 (talk) 21:12, 18 May 2024 (UTC)
 * I know the PCEPI has been reconstructed going back to at least 1929, which is roughly the same point as where CPI figures become reliable enough to be usable. –Sincerely, A Lime 21:50, 18 May 2024 (UTC)

Cents > dollars

Millions > Billions
My question is similar to the one above, but on a much larger scale (I'm converting Rockefeller money). What I currently have is:  which results in $475 million (equivalent to $8,600 million in 2023). What I would prefer, however, would be $475 million (equivalent to $8.6 billion in 2023). Is there any way to turn that 8,600 into 8.6, or is that not possible with the template? Thanks either way, DrOrinScrivello (talk) 18:11, 31 May 2024 (UTC)


 * @DrOrinScrivello:  gives you: $475 million (equivalent to $ in ). I'd note that you probably should be using   instead though, which is based on GDP deflator indices instead of the CPI.  Imzadi 1979   →   04:11, 30 June 2024 (UTC)
 * Oh, you mean I should have read the bold text at the very top of the template documentation? Novel idea, that.
 * Seriously though, thanks,, for both tips. DrOrinScrivello (talk) 14:12, 1 July 2024 (UTC)

Stock prices
I've seen a few cases where inflation was used to describe historical stock prices; for example, a company had an initial public offering at $13.72 per share in July 2007, or about $19.00 in 2023. Because this template uses the consumer price index, and shares of stock are not consumer goods, I typically remove these adjustments. Is this generally good practice? If so, could you please add stock prices as an example of situations in which not to use this template? White 720 (talk) 15:05, 8 June 2024 (UTC)
 * I think removing these adjustments is incorrect. The adjustment is meant to show how much of a person's purchasing power it would cost to purchase one share of stock at a given time. – Jonesey95 (talk) 18:46, 10 June 2024 (UTC)
 * I agree with Jonesey, with a caveat, but it depends on the context. Inflation adjustment in the example you give serves no purpose, so removing the adjustment is not really a problem in this case; however, if the current share price had also been given, then the inflation adjustment would have given the reader a comparative measure of how well the stock has performed. Inflation adjustment for the sake of just having a modern value is not useful unless it forms the basis of a comparison. Betty Logan (talk) 21:27, 10 June 2024 (UTC)
