UK Inflation Calculator
This calculator allows you to check how the value of money has changed over time. Enter an amount of money for a starting year to see how much money you'd need to purchase an equivalent set of goods in a finishing year.
The calculator will also tell you the average inflation rate and the total amount of inflation experienced between the two years.
We use our best estimate of CPI inflation data to calculate these results.
