## Inflation in 2024 and its effect on pound value

£1 in 2023 is equivalent in purchasing power to about £1.04 today. The pound had an average inflation rate of 3.90% in the last 12 months. As a result, the real value of a pound has been decreasing recently. Purchasing power decreased by 3.90% in 2024 compared to 2023. On average, you would have to spend 3.90% more money in 2024 than in 2023 for the same item.

This means that today's prices are 1.04 times as high as average prices since 2023, according to the Office for National Statistics composite price index. A pound today only buys 96.154% of what it could buy back then.

The inflation rate in 2023 was 7.07%. The current inflation rate compared to the end of last year is now 3.90%. If this number holds, £1 today will be equivalent in buying power to £1.04 next year.

Inflation rate is calculated by change in the composite price index (CPI). The CPI in 2024 is 1,417.14. It was 1,363.94 in the previous year, 2023. 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 since 2023

Our calculations use the following inflation rate formula to calculate the change in value between 2023 and today:

CPI today CPI in 2023
×
2023 GBP value
=
Today's value

Then plug in historical CPI values. The U.K. CPI was 1363.9425132808383 in the year 2023 and 1417.136271298791 in 2024:

1417.1362712987911363.9425132808383
×
£1
=
£1.04

£1 in 2023 has the same "purchasing power" or "buying power" as £1.04 in 2024.

To get the total inflation rate for the 1 years between 2023 and 2024, we use the following formula:

CPI in 2024 - CPI in 2023CPI in 2023
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

1417.136271298791 - 1363.94251328083831363.9425132808383
×

=

## 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 the current year, which is based on The Bank of England's forecast.
