Purchasing power decreased by 25.38% in 1917 compared to the previous year, 1916. On average, you would have to spend 25.38% more money in 1917 than in 1916 for the same item.
In other words, £1 in 1916 is equivalent in purchasing power to £1.25 in 1917.
The 1916 inflation rate was 18.18%. The inflation rate in 1917 was 25.38%. The 1917 inflation rate is higher compared to the average inflation rate of 4.24% per year between 1917 and 2019.
Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1917 was 16.3. It was 13 in the previous year, 1916. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation.
|Average inflation rate||25.38%|
|Converted amount (£1 base)||£1.25|
|Price difference (£1 base)||£0.25|
|CPI in 1916||13.000|
|CPI in 1917||16.300|
|Inflation in 1916||18.18%|

This inflation calculator uses the following inflation rate formula:
Then plug in historical CPI values. The UK CPI was 13 in the year 1916 and 16.3 in 1917:
£1 in 1916 has the same "purchasing power" or "buying power" as £1.25 in 1917.
To get the total inflation rate for the 1 years between 1916 and 1917, 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.
