How to calculate inflation rate for £1, 2010 to 2011

Our calculations use the following inflation rate formula to calculate the change in value between 2010 and 2011:

CPI in 2011 CPI in 2010
×
2010 GBP value
=
2011 GBP value

Then plug in historical CPI values. The U.K. CPI was 881.9 in the year 2010 and 927.8 in 2011:

927.8881.9
×
£1
=
£1.05

£1 in 2010 has the same "purchasing power" or "buying power" as £1.05 in 2011.

To get the total inflation rate for the 1 years between 2010 and 2011, we use the following formula:

CPI in 2011 - CPI in 2010CPI in 2010
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

927.8 - 881.9881.9

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 the current year, which is based on The Bank of England's forecast.
