# UK inflation rate in 1822: -13.59%

### Inflation in 1822 and Its Effect on Pound Value

Purchasing power increased by 13.59% in 1822 compared to 1821. On average, you would have to spend 13.59% less money in 1822 than in 1821 for the same item. This is an example of deflation.

In other words, £1 in 1821 is equivalent in purchasing power to about £0.86 in 1822.

The 1821 inflation rate was -11.97%. The inflation rate in 1822 was -13.59%. The 1822 inflation rate is lower compared to the average inflation rate of 2.49% per year between 1822 and 2019.

Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1822 was 8.90. It was 10.30 in the previous year, 1821. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation. Because the 1822 CPI is less than 1821 CPI, negative inflation (also known as deflation) has occurred.

### How to Calculate Inflation Rate for £1, 1821 to 1822

This inflation calculator uses the following inflation rate formula:

CPI in 1822CPI in 1821
×
1821 GBP value
=
1822 GBP value

Then plug in historical CPI values. The UK CPI was 10.3 in the year 1821 and 8.9 in 1822:

8.910.3
×
£1
=
£0.86

£1 in 1821 has the same "purchasing power" or "buying power" as £0.86 in 1822.

To get the total inflation rate for the 1 years between 1821 and 1822, we use the following formula:

CPI in 1822 - CPI in 1821CPI in 1821
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

8.9 - 10.310.3
×
100
=
-14%

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

• The Mexican war of Independence ends after Mexican revolutionary forces occupy Mexico City and the Spanish withdraw.
• 30,000 Turks are massacred during the Greek war of Independence and Tripolitsa falls.
• Antarctica is circumnavigated for the first time in an expedition led by Russian polar explorers Fabian Gottlieb von Bellinghausen.

### 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.
