Inflation in 1864 and Its Effect on Pound Value

Purchasing power increased by 1.11% in 1864 compared to 1863. On average, you would have to spend 1.11% less money in 1864 than in 1863 for the same item. This is an example of deflation.

In other words, £1 in 1863 is equivalent in purchasing power to about £0.99 in 1864.

The 1863 inflation rate was -3.23%. The inflation rate in 1864 was -1.11%. The 1864 inflation rate is lower compared to the average inflation rate of 3.17% per year between 1864 and 2019.

Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1864 was 8.90. It was 9.00 in the previous year, 1863. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation. Because the 1864 CPI is less than 1863 CPI, negative inflation (also known as deflation) has occurred.

This inflation calculator uses the following inflation rate formula:

CPI in 1864CPI in 1863
1863 GBP value
1864 GBP value

Then plug in historical CPI values. The UK CPI was 9 in the year 1863 and 8.9 in 1864:


£1 in 1863 has the same "purchasing power" or "buying power" as £0.99 in 1864.

To get the total inflation rate for the 1 years between 1863 and 1864, we use the following formula:

CPI in 1864 - CPI in 1863CPI in 1863
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

8.9 - 99

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.
