What this calculator measures
Inflation is the sustained, broad-based rise in prices: the same pesos buy less every year, and few countries have felt that as sharply as Argentina. This calculator uses the World Bank CPI for Argentina (indicator FP.CPI.TOTL, annual average) to answer one question: how many pesos from one year does an amount from another equal?
The data is baked into the tool, so the whole calculation runs in your browser with no server calls.
The 2013–2016 gap: why the series comes in two segments
Argentina is a special case in the World Bank database. The national statistics office (INDEC) was placed under government intervention in 2007 and its CPI lost credibility (the IMF censured Argentina in 2013 over it); in 2016 a statistical emergency was declared and the old index was discontinued. The current national CPI only starts in 2017.
As a result, the World Bank removed Argentina’s CPI index from its current edition and today only publishes annual inflation from 2018 onward. This calculator combines what exists:
- 1992–2012 segment: the index from the WDI historical archive (April 2014 edition, base 2005 = 100). It starts in 1992 because that is when today’s peso was born; earlier amounts were denominated in australes and older currencies.
- 2017–2024 segment: an index rebuilt with 2017 = 100 by chaining the World Bank’s current annual inflation series (
FP.CPI.TOTL.ZG).
Between 2013 and 2016 there is no comparable official data and no valid splice, so the tool only lets you compare years within the same segment.
How to use the calculator
- Enter the amount in Argentine pesos (for example,
1000). - Pick the from year: the year the amount belongs to.
- Pick the to year (2024 by default, the latest available). The selector only offers years from the same segment as the origin.
You get the CPI-adjusted equivalent, the cumulative inflation and the annualized rate — the average yearly inflation that produces that total. You can also go “backwards”, with an origin more recent than the target.
The formula
With CPI(year) as the index value for each year within the same segment:
Equivalent = amount × CPI(to) ÷ CPI(from)
Cumulative inflation (%) = (CPI(to) ÷ CPI(from) − 1) × 100
Annualized rate (%) = ((CPI(to) ÷ CPI(from))^(1 ÷ years) − 1) × 100
Argentine inflation, year by year
Year-over-year change of the average CPI according to the World Bank series (last 10 years with data):
| Year | Year-over-year inflation |
|---|---|
| 2010 | 10.78% |
| 2011 | 9.46% |
| 2012 | 10.03% |
| 2013–2016 | no official data |
| 2018 | 34.28% |
| 2019 | 53.54% |
| 2020 | 42.02% |
| 2021 | 48.41% |
| 2022 | 72.43% |
| 2023 | 133.49% |
| 2024 | 219.88% |
The climb that started in 2018 peaked in 2023–2024 with triple-digit readings, among the world’s highest.
Worked example
How much are 1,000 pesos from 2017 worth in 2024?
- CPI for 2017:
100(the base of the modern segment). - CPI for 2024:
5,596.50. - Equivalent:
1000 × 5596.50 ÷ 100 = 55,965 pesos. - Cumulative inflation:
(5596.50 ÷ 100 − 1) × 100 = 5,496.5%. - Annualized rate:
(55.965^(1/7) − 1) × 100 = 77.71%per year over 7 years.
What cost 1,000 pesos in 2017 costs about 56,000 pesos in 2024 — prices multiplied 56-fold in seven years. In the older segment, 1,000 pesos from 1992 equal 1000 × 185.85 ÷ 52.18 = 3,561.71 pesos of 2012 (256.17% cumulative).
Frequently asked questions
Where does the data come from and how often is it updated?
From the World Bank, retrieved in July 2026: the 1992–2012 segment comes from the WDI archive (April 2014 edition) and the 2017–2024 segment from the current annual inflation series. The data is refreshed once a year; the latest year available is 2024.
Why can’t I compare 2010 with 2024?
Because no comparable official series exists for 2013–2016: without those years there is no rigorous way to splice the two segments, and any number crossing the gap would be made up.
Is the 2007–2012 data reliable?
It is what INDEC published at the time and what the World Bank collected, but private and provincial estimates showed considerably higher inflation. Treat those years as the official historical record, keeping in mind they likely understate true inflation.
Why doesn’t the result match the “December” inflation from the news?
Because the World Bank uses the annual average of the index, while headlines usually quote INDEC’s December-over-December change. In 2023 the annual average was 133.49% while the December reading topped 210%; in 2024 the opposite happened. Both are correct — they measure different things.
