Then plug in historical CPI values. The UK CPI was 736.5 in the year 2004 and 757.3 in 2005:
£1 in 2004 has the same "purchasing power" or "buying power" as £1.03 in 2005.
To get the total inflation rate for the 1 years between 2004 and 2005, we use the following formula:
Plugging in the values to this equation, we get:

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.
