How to calculate inflation rate for £1, 1812 to 1815

Our calculations use the following inflation rate formula to calculate the change in value between 1812 and 1815:

CPI in 1812 CPI in 1815
×
1815 GBP value
=
1812 GBP value

Then plug in historical CPI values. The U.K. CPI was 12.7 in the year 1815 and 15.9 in 1812:

15.912.7
×
£1
=
£1.25

£1 in 1815 has the same "purchasing power" or "buying power" as £1.25 in 1812.

To get the total inflation rate for the 3 years between 1812 and 1815, we use the following formula:

CPI in 1812 - CPI in 1815CPI in 1815
×
100
=
Cumulative inflation rate (3 years)

Plugging in the values to this equation, we get:

15.9 - 12.712.7
×
100
=
25%

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.
