How to Calculate Inflation Rate for £100, 1775 to 2002
This inflation calculator uses the following inflation rate formula:
CPI in 2002CPI in 1775
×
1775 GBP value
=
2002 GBP value
Then plug in historical CPI values. The UK CPI was 7 in the year 1775 and 695.1 in 2002:
695.17
×
£100
=
£9,930
£100 in 1775 has the same "purchasing power" or "buying power" as £9,930 in 2002.
To get the total inflation rate for the 227 years between 1775 and 2002, we use the following formula:
CPI in 2002 - CPI in 1775CPI in 1775
×
100
=
Cumulative inflation rate (227 years)
Plugging in the values to this equation, we get:
695.1 - 77
×
100
=
9,830%
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.
