Purchasing power decreased by 5.20% in 2011 compared to 2010. On average, you would have to spend 5.20% more money in 2011 than in 2010 for the same item.

In other words, £1 in 2010 is equivalent in purchasing power to about £1.05 in 2011.

The 2010 inflation rate was 4.61%. The inflation rate in 2011 was 5.20%. The 2011 inflation rate is higher compared to the average inflation rate of 2.40% per year between 2011 and 2019.

Inflation rate is calculated by change in the composite price index (CPI). The CPI in 2011 was 927.80. It was 881.90 in the previous year, 2010. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation.

£1 in 2010 has the same "purchasing power" or "buying power" as £1.05 in 2011.

To get the total inflation rate for the 1 years between 2010 and 2011, we use the following formula:

CPI in 2011 - CPI in 2010CPI in 2010

Politics and news often influence economic performance. Here's what was happening at the time:

- The Copiapo mining accident in Chile ends, after 33 miners resurface having spent 69 days trapped in the ruins.
- Big Haiti earthquake kills 230,000 people and leaves most of Port-au-Prince, its capital, in ruins.
- An explosion on the Deepwater Horizon (a drilling rig), kills 11 people and spills a massive amount of oil into the Gulf of Mexico.
- The US army abolishes the "Don't Ask Don't Tell" policy, which had banned homosexuals from openly serving in the US military.

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.
