Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1916 was 13.00. It was 11.00 in the previous year, 1915. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation.

### How to Calculate Inflation Rate for £1, 1915 to 1916

This inflation calculator uses the following inflation rate formula:

CPI in 1916CPI in 1915
×
1915 GBP value
=
1916 GBP value

Then plug in historical CPI values. The U.K. CPI was 11 in the year 1915 and 13 in 1916:

1311
×
£1
=
£1.18

£1 in 1915 has the same "purchasing power" or "buying power" as £1.18 in 1916.

To get the total inflation rate for the 1 years between 1915 and 1916, we use the following formula:

CPI in 1916 - CPI in 1915CPI in 1915

=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

=
18%

Politics and news often influence economic performance. Here's what was happening at the time:

• French troops force Germans back into the Champagne region, suffering losses of 50,000 men and gaining several hundred yards.
• Germany uses poison gas for the first time in World War I.
• Almost 430,000 French, British, and Germans are killed in the Battle of Loos.
• The one-millionth Model T is produced by Ford Motor Company.

### 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.
