Inflation Calculator
See what an amount of money will be worth in the future, or was worth in the past, at a given inflation rate.
Reading the result
"Future value" shows how much you'd need at the end of the period to buy what today's amount buys now. "Past value" works backward — showing what an amount today was equivalent to that many years ago, in terms of purchasing power.
About the Inflation Calculator
The Inflation Calculator shows how a sum of money changes in purchasing power over time using an average annual inflation rate you provide. You can project what an amount will be worth in the future or what an amount in the past would be worth today.
Inflation reduces what each unit of money can buy. The calculation compounds the rate year by year: future value equals amount times (1 plus rate) to the power of years. The tool uses the rate you enter, not official price index data, so results are estimates. Actual inflation varies year to year and differs between goods and services.
