Buying power of £1 in 1800

This chart shows a calculation of buying power equivalence for £1 in 1800 (price index tracking began in 1750).

For example, if you started with £1, you would need to end with £87.97 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When £1 is equivalent to £87.97 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 1800 dollars, the chart below shows how £1 is worth less over 221 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 £1 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 1187.59624 in 2021:

1187.5962413.5
×
£1
=
£87.97

£1 in 1800 has the same "purchasing power" or "buying power" as £87.97 in 2021.

To get the total inflation rate for the 221 years between 1800 and 2021, we use the following formula:

CPI in 2021 - CPI in 1800CPI in 1800
×
100
=
Cumulative inflation rate (221 years)

Plugging in the values to this equation, we get:

1187.59624 - 13.513.5
×

=
8,697%

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.
