About this tool
This page opens the inflation calculator in projection mode: instead of historical CPI data, you set the assumptions. Enter an amount, an assumed annual inflation rate and a horizon in years, and the tool compounds the amount forward to its nominal future equivalent.
Two numbers come back besides the future value: the total percentage change over the horizon, and the mirror image — how much of today's purchasing power the same amount will retain. At 3% inflation, 1,000 today corresponds to about 1,344 in ten years, while a static 1,000 kept under the mattress will buy only about 744 worth of today's goods.
Nobody knows future inflation, so treat the rate as a dial rather than a forecast: run the same amount at 2%, 3% and 5% to bracket the outcome. Central banks in most developed economies target about 2%, and the long-run US average since 1913 is close to 3% — both are reasonable starting points.
Example. 100 dollars in 1914, when CPI-U is 10.0, equals 200 dollars in 1920, when CPI-U is 20.0.
Limit. Historical years run only from 1913 through 2025, and the series is US CPI-U annual averages.
