How to use it
- Enter amount today, annual inflation rate and term.
- The result appears straight away and updates as you edit.

How it is calculated
Future cost = Amount × (1 + inflation)^years. Purchasing power = Amount / (1 + inflation)^years.
Example
Inputs: Amount today = 1,000 your currency, Annual inflation rate = 3 %, Term = 10 years. Result: Future cost: 1,343.92; What the amount will buy then: 744.09; Purchasing power lost: 25.59%.
Limits and caveats
- Assumes the same rate every year; real inflation varies by year and by item.
- The 3% default is only an example; enter your country rate from its official statistics office.
Questions about this tool
What does purchasing power mean?
What your money can buy at today's prices. At 3% a year, 1000 buys about what 744 buys today after 10 years.
Where do I get the inflation rate?
From your country's official statistics office, which publishes the consumer price index.
Can I enter negative inflation?
Yes, down to −50%. That models falling prices, so purchasing power rises.
