Inflation Calculator

A free inflation calculator built on the U.S. Bureau of Labor Statistics CPI-U annual-average index (1913–2025). It converts any amount between two historical years, reports the cumulative price change and the average annual inflation rate over that span, and includes a projection view for future costs at an assumed rate plus a salary view that checks whether a raise beat inflation. Historical conversions are exact ratios of published index values; future projections compound whatever rate you assume. Both are buying-power estimates, not forecasts or financial advice.
