Inflation Calculator
What is today's money worth in the future — and what will tomorrow's prices cost?
Future value of your money:
Buying power of $1 then vs now:
What $100 today buys in future:
Purchasing power over time
How to use this calculator
Enter an amount, the number of years and an inflation rate, then press Calculate. You'll see the future value, the equivalent buying power, and a chart of purchasing power decline.
What the result means
Future value is what the same amount buys later — less than today. This is why long-term savings need growth above inflation to preserve purchasing power.
Frequently asked questions
What inflation rate should I use?
Long-term US inflation averages around 3%. For conservative planning, use 3-4%.
How does inflation affect my savings?
Money that grows slower than inflation loses purchasing power. That's the core case for investing rather than holding cash long-term.
