£1 in 1912 is equivalent in purchasing power to about £0.99 in 1913. The pound had an average **deflation** rate of -1.01% per year since 1912, producing a cumulative price change of -1.01%. Purchasing power *increased* by 1.01% in 1913 compared to 1912. On average, you would have to spend 1.01% *less* money in 1913 than in 1912 for the same item. This is an example of **deflation**.

This means that prices in 1913 are 1.01% lower than average prices since 1912, according to the Office for National Statistics composite price index.

The inflation rate in 1912 was 3.13%. The inflation rate in 1913 was -1.01%. The 1913 inflation rate is lower compared to the average inflation rate of 4.58% per year between 1913 and 2024.

Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1913 was 9.80. It was 9.90 in the previous year, 1912. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation. Because the 1913 CPI is less than 1912 CPI, negative inflation (also known as deflation) has occurred.

£1 in 1912 has the same "purchasing power" or "buying power" as £0.99 in 1913.

To get the total inflation rate for the 1 years between 1912 and 1913, we use the following formula:

CPI in 1913 - CPI in 1912CPI in 1912

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 the current year, which is based on The Bank of England's forecast.
