Inflation Adjusted Value Calculator
Enter an amount, a yearly inflation rate and the years, or compare an old price with a new one to find the rate.
You choose the rate. Inflation changes each year, so look up recent figures from the Office for National Statistics.

About Inflation Adjusted Value Calculator
Inflation reduces what money buys. At 3% a year, something that costs £1,000 today costs about £1,344 in ten years, and £1,000 received in ten years is worth about £744 in today's money. This calculator applies a steady yearly rate that you choose, in either direction, and shows the effect year by year.
It also works backwards. If a rent, a loaf of bread or a salary was one figure some years ago and another figure now, the third option finds the average yearly rate of price rise between them. No price index is built in, so use any rate you trust, for example a recent figure from the Office for National Statistics, and remember that real inflation changes from year to year.

Frequently asked questions
How do I adjust an amount for inflation?
Multiply by one plus the inflation rate for each year. £1,000 at 3% for 10 years is 1,000 × 1.03 to the power 10, or £1,343.92.
How do I find the value of future money today?
Divide by one plus the rate for each year. £1,000 in ten years at 3% is worth £744.09 today.
Which inflation rate should I use?
A long-run average is a reasonable guess, and many people use 2% to 3%. Official figures are published by the Office for National Statistics, and you can try several rates.
Why do prices matter for savings?
If your savings rate is lower than inflation, your money buys less each year even though the balance grows.
How does the third option work?
It takes the older price, the newer price and the number of years and finds the steady yearly rise that links them.
