Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1867 was 10.10. It was 9.50 in the previous year, 1866. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation.

1867 GBP value

Then plug in historical CPI values. The U.K. CPI was 9.5 in the year 1866 and 10.1 in 1867:

10.19.5

£1 in 1866 has the same "purchasing power" or "buying power" as £1.06 in 1867.

To get the total inflation rate for the 1 years between 1866 and 1867, we use the following formula:

CPI in 1867 - CPI in 1866CPI in 1866

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.
