How to Calculate Inflation Rate for £20,000, 1815 to 2021

Our calculations use the following inflation rate formula to calculate the change in value between 1815 and 2021:

CPI in 2021 CPI in 1815
×
1815 GBP value
=
2021 GBP value

Then plug in historical CPI values. The U.K. CPI was 12.7 in the year 1815 and 1178.1717074508606 in 2021:

1178.171707450860612.7
×
£20,000
=
£1,855,388.52

£20,000 in 1815 has the same "purchasing power" or "buying power" as £1,855,388.52 in 2021.

To get the total inflation rate for the 206 years between 1815 and 2021, we use the following formula:

CPI in 2021 - CPI in 1815CPI in 1815
×
100
=
Cumulative inflation rate (206 years)

Plugging in the values to this equation, we get:

1178.1717074508606 - 12.712.7
×
100
=

Data Source & Citation

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.
