£100 in 2020 is equivalent in purchasing power to about £242.73 in 2050, an increase of £142.73 over 30 years. The pound had an average inflation rate of 3.00% per year between 2020 and 2050, producing a cumulative price increase of 142.73%. The buying power of £100 in 2020 is predicted to be equivalent to £242.73 in 2050.

This calculation is based on future inflation assumption of 3.00% per year. Use the calculator on the left to change this prediction. Or, use the annual inflation rate calculator to view inflation in the past.

This chart shows a calculation of buying power equivalence for £100 in 2020 (price index tracking began in 1750).

For example, if you started with £100, you would need to end with £242.73 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

Future inflation is estimated at 3.00%.When £100 is equivalent to £242.73 over time, that means that the "real value" of a single U.K. pound decreases over time. In other words, a pound will pay for fewer items at the store.

This effect explains how inflation erodes the value of a pound over time. By calculating the value in 2020 dollars, the chart below shows how £100 is worth less over 30 years.

This table shows the results of the inflation prediction, with base values from the Office for National Statistics:

Raw data for these calculations comes from the composite price index published by the UK Office for National Statistics (ONS). A composite index is created by combining price data from several different published sources, both official and unofficial. The Consumer Price Index, normally used to compute inflation, has only been tracked since 1988. All inflation calculations after 1988 use the Office for National Statistics' Consumer Price Index, except for 2017, which is based on The Bank of England's forecast.
