Purchasing power decreased by 4.61% in 2010 compared to 2009. On average, you would have to spend 4.61% more money in 2010 than in 2009 for the same item.
In other words, £1 in 2009 is equivalent in purchasing power to about £1.05 in 2010.
The 2009 inflation rate was -0.53%. The inflation rate in 2010 was 4.61%. The 2010 inflation rate is higher compared to the average inflation rate of 2.71% per year between 2010 and 2019.
Inflation rate is calculated by change in the composite price index (CPI). The CPI in 2010 was 881.90. It was 843.00 in the previous year, 2009. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation.

This inflation calculator uses the following inflation rate formula:
Then plug in historical CPI values. The UK CPI was 843 in the year 2009 and 881.9 in 2010:
£1 in 2009 has the same "purchasing power" or "buying power" as £1.05 in 2010.
To get the total inflation rate for the 1 years between 2009 and 2010, 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.
