Inflation in 2023 and its effect on pound value

£1 in 2022 is equivalent in purchasing power to about £1.11 today. The pound had an average inflation rate of 10.70% in the last 12 months. As a result, the real value of a pound has been decreasing recently. Purchasing power decreased by 10.70% in 2023 compared to 2022. On average, you would have to spend 10.70% more money in 2023 than in 2022 for the same item.

This means that today's prices are 1.11 times as high as average prices since 2022, according to the Office for National Statistics composite price index. A pound today only buys 90.090% of what it could buy back then.

The inflation rate in 2022 was 10.70%. The current inflation rate compared to last year is now 10.70%. If this number holds, £1 today will be equivalent in buying power to £1.11 next year.

How to calculate inflation rate for £1 since 2022

Our calculations use the following inflation rate formula to calculate the change in value between 2022 and today:

CPI today CPI in 2022
×
2022 GBP value
=
Today's value

Then plug in historical CPI values. The U.K. CPI was 1306.91194551 in the year 2022 and 1446.7515236795698 in 2023:

1446.75152367956981306.91194551
×
£1
=
£1.11

£1 in 2022 has the same "purchasing power" or "buying power" as £1.11 in 2023.

To get the total inflation rate for the 1 years between 2022 and 2023, we use the following formula:

CPI in 2023 - CPI in 2022CPI in 2022
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

1446.7515236795698 - 1306.911945511306.91194551
×
100
=
11%

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.
