## How to Calculate Inflation Rate for £1, 1909 to 1910

Our calculations use the following inflation rate formula to calculate the change in value between 1909 and 1910:

CPI in 1909 CPI in 1910
×
1910 GBP value

## 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.
