How the US inflation calculator works
It uses the Consumer Price Index for All Urban Consumers (CPI-U), the Bureau of Labor Statistics measure of what urban households pay for a fixed basket of goods and services, as annual averages back to 1913. Value in year B = amount × CPI(B) ÷ CPI(A). $100 in 2000 (CPI 172.2) equals $186.93 in 2025 dollars (CPI 321.9): prices rose 86.9%, an average of 2.53% a year.

BLS CPI inflation calculator vs this one
The Bureau of Labor Statistics inflation calculator uses monthly CPI, so comparing, say, January to January gives slightly different results from annual averages. Annual averages are the standard way to compare whole years (salaries, prices in a given year). For contracts, use the month named in the contract.
American dollar inflation: the long view
Since 1913, prices are up about 32 times. Inflation averaged roughly 3% a year, with peaks after World War I (18% in 1918), after World War II (14% in 1947), in 1979–1981 (10% to 13.5%) and in 2022 (8.0%), and deflation in the early 1930s. The Federal Reserve targets 2% a year, measured by the PCE price index rather than CPI.
