This inflation calculator uses the following inflation rate formula:
CPI in 2009 / CPI in 1751 * 1751 GBP value = 2009 GBP value
Then plug in historical CPI values. The UK CPI was 5 in the year 1751 and 843 in 2009:
843 / 5 * £100 = £16,860
£100 in 1751 has the same "purchasing power" or "buying power" as £16,860 in 2009.
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.
