Values use the US CPI-U annual averages from 1970 to today. The result shows the same purchasing power in the end year.
What does the inflation calculator do?
It converts a dollar amount from one year to its equivalent in another year using the Consumer Price Index (CPI). The result shows what the same money would buy at different times.
Which data is used?
US CPI-U annual averages from 1970 to today. Because it relies on actual price history, results stay faithful to published inflation figures.
Why is my 2025 result different from the nominal number?
Inflation means prices rise over time, so an amount from the past buys less today, and a future amount needs more money to match past purchasing power. The tool only changes the value; it says nothing about interest earned.
Is there a limit on years?
The table starts at 1970. If you pick dates outside the range the result is not computed — this keeps every calculation reliable.
Is my data sent anywhere?
No. All calculations run locally in your browser and the CPI table is bundled with the page.
