Inflation Calculator
Find out how much buying power a dollar has lost (or gained) between any two years since 1913.
Inflation calculator
Based on annual average CPI-U (U.S. city average, all items, not seasonally adjusted) from the U.S. Bureau of Labor Statistics, available 1913–2025.
How this calculator works
The calculator compares the annual average Consumer Price Index (CPI-U) for the two years you pick. The CPI tracks the prices of
a typical basket of goods and services bought by urban U.S. households and is published monthly by the U.S. Bureau of Labor Statistics.
The formula is simple: value = amount × (CPI in later year ÷ CPI in earlier year).
Data refreshes automatically. The newest year appears once all twelve months of that year have been published. For the latest monthly reading, see today's rates.
Why your personal inflation may differ
The CPI is an average. If you spend more than the typical household on rent, childcare or medical care, which have often risen faster than average, your personal inflation rate may be higher. Learn more in How inflation works.
