Why a pound today is worth only 1% of a pound in 1807

Updated: September 11, 2020

According to the Office for National Statistics composite price index, today's prices in 2020 are 9,154.01% higher than average prices since 1807. This means that a pound today only buys 1.08% of what it could buy in 1807. The British pound experienced an average inflation rate of 2.15% per year during this period, causing the real value of a pound to decrease.

In other words, £100 in 1807 is equivalent in purchasing power to about £9,254.01 in 2020, a difference of £9,154.01 over 213 years.

The 1807 inflation rate was -2.38%. The current year-over-year inflation rate (2019 to 2020) is now 1.50%1. If this number holds, £100 today will be equivalent in buying power to £101.50 next year.

Buying power of £100 in 1807

This chart shows a calculation of buying power equivalence for £100 in 1807 (price index tracking began in 1750).

For example, if you started with £100, you would need to end with £9,254.01 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When £100 is equivalent to £9,254.01 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 1807 dollars, the chart below shows how £100 is worth less over 213 years.

£100 in 1807 has the same "purchasing power" or "buying power" as £9,254.01 in 2020.

To get the total inflation rate for the 213 years between 1807 and 2020, we use the following formula:

CPI in 2020 - CPI in 1807CPI in 1807
×
100
=
Cumulative inflation rate (213 years)

Plugging in the values to this equation, we get:

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.
