This inflation calculator uses the following inflation rate formula:

CPI in 1791CPI in 1785
×
1785 GBP value

CPI in 1791 - CPI in 1785CPI in 1785
×
100
=

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.
