How to calculate inflation rate for £100, 1757 to 1997

Our calculations use the following inflation rate formula to calculate the change in value between 1757 and 1997:

CPI in 1997 CPI in 1757
×
1757 GBP value
=
1997 GBP value

Then plug in historical CPI values. The U.K. CPI was 6.3 in the year 1757 and 621.3 in 1997:

621.36.3
×
£100
=
£9,861.90

£100 in 1757 has the same "purchasing power" or "buying power" as £9,861.90 in 1997.

To get the total inflation rate for the 240 years between 1757 and 1997, we use the following formula:

CPI in 1997 - CPI in 1757CPI in 1757
×
100
=
Cumulative inflation rate (240 years)

Plugging in the values to this equation, we get:

621.3 - 6.36.3
×
100
=
9,762%

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.
