How to calculate inflation rate for £100, 1751 to 2011

Our calculations use the following inflation rate formula to calculate the change in value between 1751 and 2011:

CPI in 2011 CPI in 1751
×
1751 GBP value
=
2011 GBP value

Then plug in historical CPI values. The U.K. CPI was 5 in the year 1751 and 927.8 in 2011:

927.85
×
£100
=
£18,556

£100 in 1751 has the same "purchasing power" or "buying power" as £18,556 in 2011.

To get the total inflation rate for the 260 years between 1751 and 2011, we use the following formula:

CPI in 2011 - CPI in 1751CPI in 1751
×
100
=
Cumulative inflation rate (260 years)

Plugging in the values to this equation, we get:

927.8 - 55
×
100
=
18,456%

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.
