How to calculate inflation rate for £100, 1772 to 2009

Our calculations use the following inflation rate formula to calculate the change in value between 1772 and 2009:

CPI in 2009 CPI in 1772
×
1772 GBP value
=
2009 GBP value

Then plug in historical CPI values. The U.K. CPI was 7.4 in the year 1772 and 843 in 2009:

8437.4
×
£100
=
£11,391.89

£100 in 1772 has the same "purchasing power" or "buying power" as £11,391.89 in 2009.

To get the total inflation rate for the 237 years between 1772 and 2009, we use the following formula:

CPI in 2009 - CPI in 1772CPI in 1772
×
100
=
Cumulative inflation rate (237 years)

Plugging in the values to this equation, we get:

843 - 7.47.4
×
100
=
11,292%

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 the current year, which is based on The Bank of England's forecast.
