How to calculate inflation rate for £1, 2019 to 2020

Our calculations use the following inflation rate formula to calculate the change in value between 2019 and 2020:

CPI in 2020 CPI in 2019
×
2019 GBP value
=
2020 GBP value

Then plug in historical CPI values. The U.K. CPI was 1131.5203575 in the year 2019 and 1151.88772393 in 2020:

1151.887723931131.5203575
×
£1
=
£1.02

£1 in 2019 has the same "purchasing power" or "buying power" as £1.02 in 2020.

To get the total inflation rate for the 1 years between 2019 and 2020, we use the following formula:

CPI in 2020 - CPI in 2019CPI in 2019
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

1151.88772393 - 1131.52035751131.5203575
×
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 the current year, which is based on The Bank of England's forecast.
