📊 Inflation Calculator

Estimate equivalent buying power, cumulative inflation, and average annual change between two years using historical U.S. CPI-U annual averages. Educational estimate only; not financial, investment, tax, legal, or budgeting advice.

This tool uses historical U.S. `CPI-U` annual averages to convert a dollar amount from one year into an equivalent buying-power amount in another year. It only reflects the historical math of that index and does not represent your personal spending basket.

This V1 only supports historical full-year annual averages. It does not include the latest monthly value for an unfinished year and does not provide future inflation forecasts, investment advice, savings advice, or spending advice.

The amount supports up to 2 decimal places and standard thousands separators. Years must be chosen from the dropdown lists.

Using the same year is valid: the equivalent amount stays the same, cumulative change is `0%`, and average annual change is shown as `N/A`.

If you convert from a later year to an earlier year, the equivalent amount may be lower than the original amount and the cumulative change may be negative.

Disclaimer: This tool is for educational estimation only. It uses embedded historical U.S. `CPI-U` annual averages for buying-power / equivalent-value conversion and is not financial, investment, tax, legal, budgeting, or spending advice. It does not guarantee actual prices, purchasing power, or future outcomes.

Privacy note: Calculations run locally by default. Your amount and year inputs are not uploaded.
