48.443.1
×
£100
=
£112.30

To get the total inflation rate for the 3 years between 1955 and 1958, we use the following formula:

CPI in 1958 - CPI in 1955CPI in 1955
×

=
Cumulative inflation rate (3 years)

Plugging in the values to this equation, we get:

48.4 - 43.143.1

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.
