## How to calculate inflation rate for £1, 1925 to 1931

Our calculations use the following inflation rate formula to calculate the change in value between 1925 and 1931:

CPI in 1931 CPI in 1925
×
1925 GBP value
=
1931 GBP value

Then plug in historical CPI values. The U.K. CPI was 18.6 in the year 1925 and 16.6 in 1931:

16.618.6
×
£1
=
£0.89

£1 in 1925 has the same "purchasing power" or "buying power" as £0.89 in 1931.

To get the total inflation rate for the 6 years between 1925 and 1931, we use the following formula:

CPI in 1931 - CPI in 1925CPI in 1925
×
100
=
Cumulative inflation rate (6 years)

Plugging in the values to this equation, we get:

16.6 - 18.618.6
×
100
=
-11%

## 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.
