How to Calculate Inflation Rate for £1, 1802 to 1805

This inflation calculator uses the following inflation rate formula:

CPI in 1805CPI in 1802
×
1802 GBP value
=
1805 GBP value

Then plug in historical CPI values. The UK CPI was 11.6 in the year 1802 and 13.1 in 1805:

13.111.6
×
£1
=
£1.13

£1 in 1802 has the same "purchasing power" or "buying power" as £1.13 in 1805.

To get the total inflation rate for the 3 years between 1802 and 1805, we use the following formula:

CPI in 1805 - CPI in 1802CPI in 1802
×
100
=
Cumulative inflation rate (3 years)

Plugging in the values to this equation, we get:

13.1 - 11.611.6
×
100
=
13%

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.
