How it works

Future value under inflation: Amount × (1 + rate/100)^years. This shows what today's amount would need to grow to just to keep the same purchasing power.

Example

10,000 today, at 3% annual inflation over 10 years, is equivalent to roughly 13,439 in future terms — meaning you'd need 13,439 then to buy what 10,000 buys now.

Assumptions & limitations

Inflation rates vary significantly by country and over time, and this calculator does not use a fixed or official rate for any country — enter a rate based on historical data or your own assumption for your currency and timeframe.

Frequently asked questions

Where do I find an accurate inflation rate?

Your country's central bank or national statistics office publishes historical inflation data — see our sources page for pointers.

Does this predict future inflation?

No — it's a calculation based on whatever rate you enter, not a forecast.
