Inflation Rate Calculator: Measure Economic Changes Over Time

Use three numbers—recent price, earlier price, and base price—to see how much costs grew. Enter them, press calculate; the tool shows inflation as a percent. Example: recent 150, earlier 120, base 120 gives 25 % inflation. U.S. consumer prices rose 3.4 % in the year to April 2024 (BLS CPI News Release, 2024).
