How to calculate inflation rate for £100, 1845 to 1850

Our calculations use the following inflation rate formula to calculate the change in value between 1845 and 1850:

CPI in 1850 CPI in 1845
×
1845 GBP value
=
1850 GBP value

Then plug in historical CPI values. The U.K. CPI was 9.3 in the year 1845 and 8.4 in 1850:

8.49.3
×
£100
=
£90.32

£100 in 1845 has the same "purchasing power" or "buying power" as £90.32 in 1850.

To get the total inflation rate for the 5 years between 1845 and 1850, we use the following formula:

CPI in 1850 - CPI in 1845CPI in 1845
×
100
=
Cumulative inflation rate (5 years)

Plugging in the values to this equation, we get:

8.4 - 9.39.3
×
100
=
-10%

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.
