UK Inflation Calculator


Inflation in 1797 and Its Effect on Pound Value

Purchasing power increased by 10.00% in 1797 compared to 1796. On average, you would have to spend 10.00% less money in 1797 than in 1796 for the same item. This is an example of deflation.

In other words, £1 in 1796 is equivalent in purchasing power to about £0.90 in 1797.

The 1796 inflation rate was 6.38%. The inflation rate in 1797 was -10.00%. The 1797 inflation rate is lower compared to the average inflation rate of 2.20% per year between 1797 and 2019.

Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1797 was 9.00. It was 10.00 in the previous year, 1796. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation. Because the 1797 CPI is less than 1796 CPI, negative inflation (also known as deflation) has occurred.

How to Calculate Inflation Rate for £1, 1796 to 1797

This inflation calculator uses the following inflation rate formula:

CPI in 1797CPI in 1796
1796 GBP value
1797 GBP value

Then plug in historical CPI values. The UK CPI was 10 in the year 1796 and 9 in 1797:


£1 in 1796 has the same "purchasing power" or "buying power" as £0.90 in 1797.

To get the total inflation rate for the 1 years between 1796 and 1797, we use the following formula:

CPI in 1797 - CPI in 1796CPI in 1796
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

9 - 1010

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.
