UK Inflation Calculator


Inflation in 1807 and Its Effect on Pound Value

Purchasing power increased by 2.38% in 1807 compared to 1806. On average, you would have to spend 2.38% less money in 1807 than in 1806 for the same item. This is an example of deflation.

In other words, £1 in 1806 is equivalent in purchasing power to about £0.98 in 1807.

The 1806 inflation rate was -3.82%. The inflation rate in 1807 was -2.38%. The 1807 inflation rate is lower compared to the average inflation rate of 2.15% per year between 1807 and 2019.

Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1807 was 12.30. It was 12.60 in the previous year, 1806. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation. Because the 1807 CPI is less than 1806 CPI, negative inflation (also known as deflation) has occurred.

How to Calculate Inflation Rate for £1, 1806 to 1807

This inflation calculator uses the following inflation rate formula:

CPI in 1807CPI in 1806
1806 GBP value
1807 GBP value

Then plug in historical CPI values. The UK CPI was 12.6 in the year 1806 and 12.3 in 1807:


£1 in 1806 has the same "purchasing power" or "buying power" as £0.98 in 1807.

To get the total inflation rate for the 1 years between 1806 and 1807, we use the following formula:

CPI in 1807 - CPI in 1806CPI in 1806
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

12.3 - 12.612.6

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.
