Buying power of £100 in 1815

This chart shows a calculation of buying power equivalence for £100 in 1815 (price index tracking began in 1750).

For example, if you started with £100, you would need to end with £101.57 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When £100 is equivalent to £101.57 over time, that means that the "real value" of a single U.K. pound decreases over time. In other words, a pound will pay for fewer items at the store.

This effect explains how inflation erodes the value of a pound over time. By calculating the value in 1815 dollars, the chart below shows how £100 is worth less over 4 years.

How to calculate inflation rate for £100, 1815 to 1819

Our calculations use the following inflation rate formula to calculate the change in value between 1815 and 1819:

CPI in 1819 CPI in 1815
×
1815 GBP value
=
1819 GBP value

Then plug in historical CPI values. The U.K. CPI was 12.7 in the year 1815 and 12.9 in 1819:

12.912.7
×
£100
=
£101.57

£100 in 1815 has the same "purchasing power" or "buying power" as £101.57 in 1819.

To get the total inflation rate for the 4 years between 1815 and 1819, we use the following formula:

CPI in 1819 - CPI in 1815CPI in 1815
×
100
=
Cumulative inflation rate (4 years)

Plugging in the values to this equation, we get:

12.9 - 12.712.7
×
100
=
2%

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.
