Purchasing power decreased by 1.50% in 2020 compared to 2019. On average, you would have to spend 1.50% more money in 2020 than in 2019 for the same item.

In other words, £1 in 2019 is equivalent in purchasing power to about £1.01 in 2020.

The 2019 inflation rate was 1.80%. The current year-over-year inflation rate (2019 to 2020) is now 1.50%^{1}.
If this number holds, £1 today will be equivalent in buying power to £1.01 next year.

Inflation rate is calculated by change in the composite price index (CPI). The CPI in 2020 is 1,138.24. It was 1,121.42 in the previous year, 2019. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation.

£1 in 2019 has the same "purchasing power" or "buying power" as £1.01 in 2020.

To get the total inflation rate for the 1 years between 2019 and 2020, we use the following formula:

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.
