How to calculate inflation rate for £1, 1805 to 1808

Our calculations use the following inflation rate formula to calculate the change in value between 1805 and 1808:

CPI in 1808 CPI in 1805
×
1805 GBP value
=
1808 GBP value

Then plug in historical CPI values. The U.K. CPI was 13.1 in the year 1805 and 12.8 in 1808:

12.813.1
×
£1
=
£0.98

£1 in 1805 has the same "purchasing power" or "buying power" as £0.98 in 1808.

To get the total inflation rate for the 3 years between 1805 and 1808, we use the following formula:

CPI in 1808 - CPI in 1805CPI in 1805
×
100
=
Cumulative inflation rate (3 years)

Plugging in the values to this equation, we get:

12.8 - 13.113.1
×
100
=
-2%

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.
