About the Inflation Calculator
An inflation calculator shows how prices and the value of money change over time at a given inflation rate. Enter an amount, an average annual inflation rate and a number of years to see what that amount will cost in the future and what its purchasing power is in today's money.
How Inflation Calculator works
Future cost = amount × (1 + inflation)years.
Today's buying power = amount ÷ (1 + inflation)years.
Example: ,000 at 3% inflation for 10 years would cost about ,344; its buying power then equals ~4 today.
Common uses
- See the future cost of an expense
- Understand how savings lose value to inflation
- Compare prices across years
- Plan for retirement or long-term goals
Frequently asked questions
What inflation rate should I use?
Long-term average inflation is often around 2–3% per year, but it varies by country and period.
What is purchasing power?
How much your money can actually buy. Inflation reduces purchasing power over time, so the same amount buys less later.
