Buying power of £100 in 1751

This chart shows a calculation of buying power equivalence for £100 in 1751 (price index tracking began in 1750).

For example, if you started with £100, you would need to end with £20,400 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When £100 is equivalent to £20,400 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 1751 dollars, the chart below shows how £100 is worth less over 264 years.

According to the Office for National Statistics, each of these GBP amounts below is equal in terms of what it could buy at the time:

How to calculate inflation rate for £100, 1751 to 2015

Our calculations use the following inflation rate formula to calculate the change in value between 1751 and 2015:

CPI in 2015 CPI in 1751
×
1751 GBP value
=
2015 GBP value

Then plug in historical CPI values. The U.K. CPI was 5 in the year 1751 and 1020 in 2015:

10205
×
£100
=
£20,400

£100 in 1751 has the same "purchasing power" or "buying power" as £20,400 in 2015.

To get the total inflation rate for the 264 years between 1751 and 2015, we use the following formula:

CPI in 2015 - CPI in 1751CPI in 1751
×
100
=
Cumulative inflation rate (264 years)

Plugging in the values to this equation, we get:

1020 - 55
×
100
=
20,300%

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.
