How to calculate inflation rate for £1, 1820 to 1829

Our calculations use the following inflation rate formula to calculate the change in value between 1820 and 1829:

CPI in 1829 CPI in 1820
×
1820 GBP value
=
1829 GBP value

Then plug in historical CPI values. The U.K. CPI was 11.7 in the year 1820 and 10.3 in 1829:

10.311.7
×
£1
=
£0.88

£1 in 1820 has the same "purchasing power" or "buying power" as £0.88 in 1829.

To get the total inflation rate for the 9 years between 1820 and 1829, we use the following formula:

CPI in 1829 - CPI in 1820CPI in 1820
×
100
=
Cumulative inflation rate (9 years)

Plugging in the values to this equation, we get:

10.3 - 11.711.7
×
100
=
-12%

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.
