Inflation Calculator
Enter an amount, an inflation rate, and a time frame to see what that money becomes in the future — both the future price of the same thing and the real purchasing power of today's money.
How it works
Future cost is amount × (1 + inflation)^years; purchasing power divides instead. Even small yearly inflation, compounded over decades, sharply cuts what money can buy. The inflation rate is an assumption.

Frequently Asked Questions
How is future purchasing power calculated?
It divides the amount today by (1 + inflation)^years, showing how much less the same money buys in the future.
What inflation rate should I use?
There is no single answer, but 2–3% is a common long-run assumption. It varies by era and country, so try a few values.
Does savings interest not cover it?
If your interest is below inflation, real value still falls. What matters is the real return — nominal interest minus inflation.
