How the Inflation Calculator Works
Inflation erodes the value of money over time: as prices rise, each dollar buys less. This calculator compounds a yearly inflation rate to show either what today’s money will cost in future (the same basket of goods gets pricier) or what a future sum is worth in today’s money (discounting it back).
The long-run average in the US is around 3% a year, though it varies. Enter the average rate for the period you care about — the calculator shows the total inflation over the span and how much purchasing power is kept or lost.
future cost = amount × (1 + rate)^years
Frequently Asked Questions
How much will money be worth in the future?
Enter an amount, the number of years and an inflation rate. At 3% a year, $1,000 buys what about $744 buys today after a decade.
What inflation rate should I use?
The long-run US average is roughly 3% a year. For a specific past period, use that period’s average rate.
What is purchasing power?
How much your money can actually buy. Inflation reduces it over time, so the same dollar amount buys fewer goods each year.
