About Currency & Inflation calculators
Exchange rates move constantly. The currency tools use live mid-market rates, which are the benchmark between buyers and sellers. Banks and card networks usually add a margin, so the rate you receive can be slightly worse.
The inflation calculator uses the Consumer Price Index for All Urban Consumers (CPI-U) published by the Bureau of Labor Statistics. It includes annual averages from 2000 and monthly values through September 2026, when the 12-month inflation rate was 3.7%.
Money across borders and time
Exchange rates change constantly, and inflation slowly changes what money can buy. The currency converter uses current rates for a quick conversion, and the cross-rate matrix compares several currencies at once.
Understanding inflation
Inflation means prices rise over time. The inflation calculator shows how much a past amount would be worth today, which helps when judging old prices or long-term savings goals.
Keep in mind
Banks and card networks add their own margins to exchange rates, so the rate you receive can differ from the mid-market rate shown here.
