How to Calculate Inflation Rate for £1, 2013 to 2015

Our calculations use the following inflation rate formula to calculate the change in value between 2013 and 2015:

CPI in 2013 CPI in 2015
×
2015 GBP value
=
2013 GBP value

Then plug in historical CPI values. The U.K. CPI was 1020 in the year 2015 and 986.7 in 2013:

986.71020
×
£1
=
£0.97

£1 in 2015 has the same "purchasing power" or "buying power" as £0.97 in 2013.

To get the total inflation rate for the 2 years between 2013 and 2015, we use the following formula:

CPI in 2013 - CPI in 2015CPI in 2015
×
100
=
Cumulative inflation rate (2 years)

Plugging in the values to this equation, we get:

986.7 - 10201020
×
100
=
-3%

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.
