Inflation in 1815 and its effect on pound value

£1 in 1814 is equivalent in purchasing power to about £0.89 in 1815. The pound had an average deflation rate of -10.56% per year since 1814, producing a cumulative price change of -10.56%. Purchasing power increased by 10.56% in 1815 compared to 1814. On average, you would have to spend 10.56% less money in 1815 than in 1814 for the same item. This is an example of deflation.

This means that prices in 1815 are 10.56% lower than average prices since 1814, according to the Office for National Statistics composite price index.

The inflation rate in 1814 was -12.88%. The inflation rate in 1815 was -10.56%. The 1815 inflation rate is lower compared to the average inflation rate of 2.28% per year between 1815 and 2024.

Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1815 was 12.70. It was 14.20 in the previous year, 1814. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation. Because the 1815 CPI is less than 1814 CPI, negative inflation (also known as deflation) has occurred.

How to calculate inflation rate for £1, 1814 to 1815

Our calculations use the following inflation rate formula to calculate the change in value between 1814 and 1815:

CPI in 1815 CPI in 1814
×
1814 GBP value
=
1815 GBP value

Then plug in historical CPI values. The U.K. CPI was 14.2 in the year 1814 and 12.7 in 1815:

12.714.2
×
£1
=
£0.89

£1 in 1814 has the same "purchasing power" or "buying power" as £0.89 in 1815.

To get the total inflation rate for the 1 years between 1814 and 1815, we use the following formula:

CPI in 1815 - CPI in 1814CPI in 1814
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

12.7 - 14.214.2
×
100
=
-11%

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.
