How to use Inflation Calculator

Provide the amount, inflation rate, and time horizon, and the calculator will show how the value changes when purchasing power shifts over time.

What this calculator is for

This calculator is for budgeting, retirement planning, tuition estimates, and any cost comparison where nominal dollars alone can be misleading. It helps show the difference between money value and spending power.

Tips

Long time horizons amplify small rate changes, so test more than one inflation assumption before relying on a single result.
Use a rate that matches the context of the cost you are studying when possible instead of assuming all prices rise at the same pace.
