Buying power of £1 in 1973

This chart shows a calculation of buying power equivalence for £1 in 1973 (price index tracking began in 1750).

For example, if you started with £1, you would need to end with £0.69 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When £1 is equivalent to £0.69 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.

How to Calculate Inflation Rate for £1, 1973 to 1975

Our calculations use the following inflation rate formula to calculate the change in value between 1973 and 1975:

CPI in 1973 CPI in 1975
×
1975 GBP value
=
1973 GBP value

Then plug in historical CPI values. The U.K. CPI was 134.8 in the year 1975 and 93.5 in 1973:

93.5134.8
×
£1
=
£0.69

£1 in 1975 has the same "purchasing power" or "buying power" as £0.69 in 1973.

To get the total inflation rate for the 2 years between 1973 and 1975, we use the following formula:

CPI in 1973 - CPI in 1975CPI in 1975
×
100
=
Cumulative inflation rate (2 years)

Plugging in the values to this equation, we get:

93.5 - 134.8134.8
×
100
=
-31%

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.
