Inflation Calculator
See how prices rise — and money loses value — at a steady inflation rate.
For information only. Results are estimates based on the numbers you enter and a constant rate. They are not financial, tax or investment advice — real returns, fees, taxes and lender terms vary. Speak to a qualified adviser before making financial decisions.
How it works
- Enter an amount of money today.
- Enter an annual inflation rate and the number of years.
- See the future cost of the same things and what today's money will be worth.
Frequently asked questions
How does inflation reduce purchasing power?
When prices rise, the same amount of money buys less. At 3% inflation, something costing 1,000 today costs about 1,344 in 10 years, and 1,000 then buys what 744 buys today.
What inflation rate should I use?
Many central banks target about 2% a year, but actual inflation varies by country and year. Check your national statistics office for recent figures.
Does this use historical inflation data?
No. It projects a constant rate you choose, which is ideal for planning. For exact historical comparisons, use official consumer price index (CPI) data.
How can I protect savings from inflation?
Savings need to earn more than inflation to grow in real terms. Compare interest and investment returns with the inflation rate.
What will things cost in future?
Inflation quietly erodes the value of money. This calculator shows how much more the same basket of goods will cost after a number of years, and how much today's money will really be worth.
Planning with inflation
Use it to set savings goals, estimate future school fees, check whether a salary increase beats inflation, or plan retirement income in today's money.
