Inflation Calculator
See how inflation erodes purchasing power over time. Enter an amount, a start year, and an end year to find out what your money is really worth after accounting for inflation.
How to Use
Enter the dollar amount you want to adjust, the start year, and the end year. The calculator uses an average annual inflation rate (which you can customize) to show you how purchasing power changes over time. A year-by-year breakdown shows the gradual effect of inflation.
Formula
The formula compounds the annual inflation rate over the number of years between your start and end dates. A positive result shows what you would need in the end year to have the same purchasing power as the original amount in the start year. The historical average US inflation rate is approximately 3.0% per year.
