What this Mexico inflation calculator does
Inflation is the sustained rise in the general price level: as years go by, the same pesos buy less and less. This tool converts any amount of Mexican pesos between two years using Mexico’s real Consumer Price Index (CPI) as published by the World Bank (indicator FP.CPI.TOTL, base 2010 = 100). You never have to look up or type an inflation rate yourself: the annual index values from 1990 through 2025 are built into the calculator, and everything runs locally in your browser with no data sent anywhere.
It answers practical questions in one step: what are 1,000 pesos from 2010 worth today? How much has the cost of living climbed since you started your first job? What raise would you need just to break even with inflation?
How to use it
- Enter the amount in pesos you want to convert (say,
1000). - Pick the origin year, the year that money belongs to.
- Pick the target year (it defaults to 2025, the latest year available).
You instantly get the updated equivalent (what you would need in the target year to buy the same things), the cumulative inflation over the period, and the annualized rate, the geometric average per year. The core formula is amount × CPI(target) ÷ CPI(origin). Choosing the same year in both fields simply returns 0%. You can also run it backwards, from 2025 to 2010 for instance, to deflate a current figure into the pesos of an earlier era.
Mexico’s year-over-year inflation (last 10 years)
Computed from the same World Bank index the tool uses, as (CPI of the year ÷ CPI of the previous year − 1) × 100:
| Year | Annual inflation |
|---|---|
| 2016 | 2.82% |
| 2017 | 6.04% |
| 2018 | 4.90% |
| 2019 | 3.63% |
| 2020 | 3.40% |
| 2021 | 5.69% |
| 2022 | 7.89% |
| 2023 | 5.53% |
| 2024 | 4.72% |
| 2025 | 3.81% |
The post-pandemic spike stands out: 7.89% in 2022, the highest in about two decades, followed by a gradual cooldown to 3.81% in 2025.
Worked example
What are 1,000 pesos from 2010 worth today?
- CPI for 2010:
100(it is the base year of the series). - CPI for 2025:
191.45. - Equivalent:
1000 × 191.45 ÷ 100 = 1,914.50 MXN. - Cumulative inflation:
(191.45 ÷ 100 − 1) × 100 = 91.45%. - Annualized rate over 15 years:
(1.9145 ^ (1/15) − 1) × 100 = 4.42%per year.
In other words, buying in 2025 what 1,000 pesos bought in 2010 takes 1,914.50 pesos: prices nearly doubled in 15 years even though average inflation was a seemingly mild 4.42% a year. Another example: 500 pesos from 1995, the year of the “Tequila crisis”, equal 500 × 191.45 ÷ 26.39 = 3,627.32 pesos of 2025, a cumulative inflation of 625.46%.
Frequently asked questions
Where does the data come from and how often is it updated?
From the World Bank indicator FP.CPI.TOTL (consumer price index, base 2010 = 100), which in turn compiles Mexico’s official figures produced by INEGI. We retrieved the series in July 2026 and baked it into the tool. The World Bank publishes each year’s figure once a year, so the latest available year is 2025; we refresh the series when the new data point appears.
Why does the series start in 1990?
The World Bank actually has Mexican data back to 1960, but with the 2010 = 100 base every index before 1990 is a tiny number (1960 is 0.0129) that loses accuracy when rounded, and those decades include hyperinflation and the currency change from old pesos to new pesos in 1993. Restricting the calculator to 1990-2025 keeps every conversion reliable and meaningful.
Is this the same as INEGI’s INPC?
It is the same underlying measurement: the World Bank takes the national consumer price index compiled by INEGI and rescales it to annual averages with base 2010 = 100. Small decimal differences versus the biweekly or monthly INPC are possible, because this series works with full-year averages rather than specific months.
What does the annualized rate mean?
It is the geometric average: the constant yearly inflation that, compounded over every year of the period, produces exactly the observed cumulative inflation. It beats a simple average because inflation compounds, with each year applying on top of already-higher prices, just like compound interest.
Can I convert from a recent year to an older one?
Yes. Set 2025 as origin and 2010 as target and the tool deflates: it tells you how many 2010 pesos your current amount is worth. Cumulative inflation will show as negative, since you are moving backwards along the price series.
