Inflation settings
Tip: many countries publish historical CPI data you can use for the rate.
See how inflation changes the value of money over time, free. Enter an amount, a period and an average inflation rate to compare past and future purchasing power.
Enter an amount, a start year, an end year and the average annual inflation rate. The calculator compounds the rate over the number of years to show the future equivalent of your money, how much purchasing power is lost, and what the amount would have been worth in the past. It is a simple compound-growth model: value x (1 + rate)^years.
The result is only as good as the rate you enter. For historical accuracy, look up your country's actual CPI inflation for the period (around 2-3% per year in the US over recent decades, much higher elsewhere). For future estimates, the rate is a guess: try a few scenarios to see the range of outcomes.
