Purchasing power decreased by 12.50% in 1799 compared to the previous year, 1798. On average, you would have to spend 12.50% more money in 1799 than in 1798 for the same item.
In other words, £100 in 1798 is equivalent in purchasing power to £112.50 in 1799.
The 1798 inflation rate was -2.22%. The inflation rate in 1799 was 12.50%. The 1799 inflation rate is higher compared to the average inflation rate of 2.17% per year between 1799 and 2018.
Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1799 was 9.9. It was 8.8 in the previous year, 1798. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation.

This inflation calculator uses the following inflation rate formula:
Then plug in historical CPI values. The UK CPI was 8.8 in the year 1798 and 9.9 in 1799:
£100 in 1798 has the same "purchasing power" or "buying power" as £112.50 in 1799.
To get the total inflation rate for the 1 years between 1798 and 1799, we use the following formula:
Plugging in the values to this equation, we get:
Politics and news often influence economic performance. Here's what was happening at the time:
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.
