# UK inflation rate in 1922: -13.85%

### Inflation in 1922 and Its Effect on Pound Value

Purchasing power increased by 13.85% in 1922 compared to 1921. On average, you would have to spend 13.85% less money in 1922 than in 1921 for the same item. This is an example of deflation.

In other words, £1 in 1921 is equivalent in purchasing power to about £0.86 in 1922.

The 1921 inflation rate was -8.70%. The inflation rate in 1922 was -13.85%. The 1922 inflation rate is lower compared to the average inflation rate of 4.24% per year between 1922 and 2019.

Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1922 was 19.90. It was 23.10 in the previous year, 1921. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation. Because the 1922 CPI is less than 1921 CPI, negative inflation (also known as deflation) has occurred.

### How to Calculate Inflation Rate for £1, 1921 to 1922

This inflation calculator uses the following inflation rate formula:

CPI in 1922CPI in 1921
×
1921 GBP value

Then plug in historical CPI values. The UK CPI was 23.1 in the year 1921 and 19.9 in 1922:

19.923.1
×
£1
=
£0.86

£1 in 1921 has the same "purchasing power" or "buying power" as £0.86 in 1922.

To get the total inflation rate for the 1 years between 1921 and 1922, we use the following formula:

CPI in 1922 - CPI in 1921CPI in 1921
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

19.9 - 23.123.1

=
-14%

### 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.
