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.

### How to Calculate Inflation Rate for £1, 2010 to 2011

This inflation calculator uses the following inflation rate formula:

CPI in 2011CPI in 2010
×
2010 GBP value

2011 GBP value

Then plug in historical CPI values. The UK CPI was 881.9 in the year 2010 and 927.8 in 2011:

927.8881.9
×
£1
=
£1.05

£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
×

=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

927.8 - 881.9881.9

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.

### 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.
