Related tools

Enter an amount in today's dollars, a time period, and an inflation rate to estimate the future amount needed for the same purchasing power and how much today's money would be worth later.

How to use this tool

Enter an amount in today's dollars, a time horizon in years, and an inflation rate—use a preset or type a custom percent. Calculate to see future amount needed, purchasing-power loss, and a year-by-year path.

Worked example

Example: $1,000 today at 3% inflation for 10 years requires about $1,344 later to buy the same basket of goods.

How it works

Applies a constant annual inflation rate to show how much you would need in the future to match today's purchasing power, and how today's dollars shrink over time. Preset rates (2% Fed target, 3% long-run average, 4% elevated) are available; custom rates are always supported.
