How to Calculate Inflation Rate for £100, 1765 to 2012

Our calculations use the following inflation rate formula to calculate the change in value between 1765 and 2012:

CPI in 2012 CPI in 1765
×
1765 GBP value
=
2012 GBP value

Then plug in historical CPI values. The U.K. CPI was 6.4 in the year 1765 and 957.6 in 2012:

957.66.4
×
£100
=
£14,962.50

£100 in 1765 has the same "purchasing power" or "buying power" as £14,962.50 in 2012.

To get the total inflation rate for the 247 years between 1765 and 2012, we use the following formula:

CPI in 2012 - CPI in 1765CPI in 1765
×
100
=
Cumulative inflation rate (247 years)

Plugging in the values to this equation, we get:

957.6 - 6.46.4
×
100
=
14,863%

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.
