Future purchasing power of this amount: 781.2
Loss of purchasing power: 21.9 %

Uses a constant average rate. Actual inflation varies year to year; check your national statistics office for official figures.

Future cost = amount × (1 + inflation)^years

How to use

Enter an amount in today's money.
Enter an average yearly inflation rate.
Enter the number of years.
Read the future cost and purchasing power.

How it works

Inflation compounds like interest: future cost = amount × (1 + rate)^years. Purchasing power is the inverse: amount ÷ (1 + rate)^years.

At 2.5% a year, prices rise about 28% in 10 years, so 1,000 kept in cash buys what 781 buys today.

Examples

10 years at 2.5%: 1,000 today → 1,280.08 needed; purchasing power falls to 781.20.
