Purchasing power increased by 4.05% in 1931 compared to the previous year, 1930. On average, you would have to spend 4.05% less money in 1931 than in 1930 for the same item. This is an example of deflation.
In other words, £1 in 1930 is equivalent in purchasing power to £0.96 in 1931.
The 1930 inflation rate was -2.81%. The inflation rate in 1931 was -4.05%. The 1931 inflation rate is lower compared to the average inflation rate of 4.94% per year between 1931 and 2018.
Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1931 was 16.6. It was 17.3 in the previous year, 1930. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation. Because the 1931 CPI is less than 1930 CPI, negative inflation (also known as deflation) has occurred.
|Average inflation rate||-4.05%|
|Converted amount (£1 base)||£0.96|
|Price difference (£1 base)||£-0.04|
|CPI in 1930||17.300|
|CPI in 1931||16.600|
|Inflation in 1930||-2.81%|
|Inflation in 1931||-4.05%|
This inflation calculator uses the following inflation rate formula:
Then plug in historical CPI values. The UK CPI was 17.3 in the year 1930 and 16.6 in 1931:
£1 in 1930 has the same "purchasing power" or "buying power" as £0.96 in 1931.
To get the total inflation rate for the 1 years between 1930 and 1931, 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.
