£1 in 1801 is equivalent in purchasing power to about £0.77 in 1802.
The pound had an average **deflation** rate of -23.18% per year since 1801, producing a cumulative price change of -23.18%.
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**.

This means that prices in 1802 are 23.18% lower than average prices since 1801, according to the Office for National Statistics composite price index.

The inflation rate in 1801 was 11.85%. The inflation rate in 1802 was -23.18%. The 1802 inflation rate is lower compared to the average inflation rate of 2.14% per year between 1802 and 2021.

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.

Our calculations use the following inflation rate formula to calculate the change in value between 1801 and 1802:

CPI in 1802

1802 GBP value

Then plug in historical CPI values. The U.K. CPI was 15.1 in the year 1801 and 11.6 in 1802:

11.615.1

£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

Politics and news often influence economic performance. Here's what was happening at the time:

- Formation of the United Kingdom of Great Britain and Ireland, after the Irish Parliament voted to join the Union.
- Giuseppe Piazzi, an Italian monk, discovers Ceres a dwarf planet.
- Thomas Jefferson becomes the first US President to be inaugurated in Washington D.C.

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.
