Inflation in 1802 and Its Effect on Pound Value
Purchasing power increased by 23.18% in 1802 compared to 1801. On average, you would have to spend 23.18% less money in 1802 than in 1801 for the same item. This is an example of deflation.
In other words, £1 in 1801 is equivalent in purchasing power to about £0.77 in 1802.
The 1801 inflation rate was 11.85%. The inflation rate in 1802 was -23.18%. The 1802 inflation rate is lower compared to the average inflation rate of 2.13% per year between 1802 and 2019.
Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1802 was 11.60. It was 15.10 in the previous year, 1801. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation. Because the 1802 CPI is less than 1801 CPI, negative inflation (also known as deflation) has occurred.

How to Calculate Inflation Rate for £1, 1801 to 1802
This inflation calculator uses the following inflation rate formula:
CPI in 1802CPI in 1801
×
1801 GBP value
=
1802 GBP value
Then plug in historical CPI values. The UK CPI was 15.1 in the year 1801 and 11.6 in 1802:
11.615.1
×
£1
=
£0.77
£1 in 1801 has the same "purchasing power" or "buying power" as £0.77 in 1802.
To get the total inflation rate for the 1 years between 1801 and 1802, we use the following formula:
CPI in 1802 - CPI in 1801CPI in 1801
×
100
=
Cumulative inflation rate (1 years)
Plugging in the values to this equation, we get:
11.6 - 15.115.1

=
-23%

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.
