What could your money buy in the future?

Explore how an assumed inflation rate changes buying power and the future amount needed to buy the same things.

Enter your own inflation assumption. This is a projection, not historical inflation data or a forecast.

Purchasing-power calculator inputs

Use the same currency throughout. Enter numbers without commas or currency symbols, for example 1000.50. Amounts allow two decimal places; rates allow six.

Your starting point

The price or amount whose purchasing power you want to explore.
A constant annual price change, from −20% to 100%. Negative means falling prices.
Use a whole number from 1 to 600. For 5 years, enter 60.

Calculate once. After that, valid edits update your result automatically.

Understand this estimate

Worked example

At 10% annual inflation for 24 months, buying what costs 1000 today would take 1210. An unchanged amount of 1000 would buy what 826.45 buys today.

How we calculate this

Price factor = (1 + annual inflation / 100) raised to months / 12. Future amount needed = amount today × price factor. Buying power of unchanged money = amount today ÷ price factor.

No investment return is applied. The two figures answer different questions; they are not alternative investments. We retain fractional cents internally and round for display.
