What this calculator does
Every input on this inflation calculator maps to a real decision, so the output is something you can act on immediately, not a rough ballpark you'll have to double-check elsewhere.
Inflation reduces the purchasing power of money over time.
How to use the Inflation Calculator
- Start by entering **Today's Amount** — this anchors every downstream number in the inflation calculator.
- Fill in **Inflation Rate** to reflect your specific situation.
- Set **Years**; the result and chart recalculate the moment you finish typing.
- Review the breakdown card for the components that make up the headline number.
- Use Copy, Share, or Print to save the exact scenario — or star it to keep it in your favorites.
The formula
Future = Amount × (1 + rate)^years
Worked example
