## How to Calculate Inflation Rate for £100 since 1800

Our calculations use the following inflation rate formula to calculate the change in value between 1800 and today:

CPI today CPI in 1800
×
1800 GBP value
=
Today's value

Then plug in historical CPI values. The U.K. CPI was 13.5 in the year 1800 and 1138.2433607545 in 2020:

1138.243360754513.5
×
£100
=
£8,431.43

£100 in 1800 has the same "purchasing power" or "buying power" as £8,431.43 in 2020.

To get the total inflation rate for the 220 years between 1800 and 2020, we use the following formula:

CPI in 2020 - CPI in 1800CPI in 1800
×
100
=
Cumulative inflation rate (220 years)

Plugging in the values to this equation, we get:

1138.2433607545 - 13.513.5
×
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 2017, which is based on The Bank of England's forecast.
