This free inflation calculator has two modes. The historical mode uses real US Consumer Price Index (CPI-U) data to show what a dollar amount from one year is worth in another — from 1913 to 2024 — along with the cumulative price change and the average annual inflation rate over that span. The flat-rate mode projects how prices and purchasing power change at an inflation rate you choose.
