CPI Calculator: Measure Inflation and Price Changes Over Time

Use the CPI calculator by entering a base year (e.g., 1995), a current year (e.g., 2024) and each item’s quantity plus past-and-present prices; it returns Consumer Price Index and inflation rate. U.S. consumer prices rose 4.9 % year-over-year in April 2023 (BLS News Release, 2023).
