Inflation Calculator
How much was your money worth in the past, and what is it worth today? Pick a country and two dates and see the inflation rate, what your amount is worth, charts and a full data table. The data is fetched live from the World Bank, the US BLS, Statistics Canada and the UK ONS, so it stays up to date.

How it works
Inflation is measured with a consumer price index (CPI): the cost of a typical basket of goods and services, indexed to a base year. To compare two periods, divide the index at the later period by the index at the earlier one. If the CPI was 100 in 2000 and 188 in 2025, prices rose 88% and 100 in 2000 buys what 188 buys in 2025.
Value in To = Amount × CPITo ÷ CPIFrom
Where the data comes from
The numbers are fetched from the publishers each time the cache refreshes (about twice a day), so the latest releases appear without any manual update. If a publisher is unreachable the calculator falls back to its last saved copy and says so under the result.
Good to know
- Annual vs monthly. The United States, Canada and the United Kingdom offer month-by-month data. Annual mode uses the average of the year; the current year is shown as a year-to-date average (YTD).
- Currencies. Results use the country's current currency symbol. In countries that redenominated their currency (for example Zimbabwe, Turkey or Brazil) older values are in the old units, which is why the index, not the symbol, is what matters.
- CPI is an average. Your own basket (rent, tuition, fuel) may have inflated faster or slower than the national index.
- Old share links (mes.fm/inflationcalculator/s/…) still open: they are matched to the closest year in the new data.
