## How to Calculate Inflation Rate for £1, 1976 to 1977

Our calculations use the following inflation rate formula to calculate the change in value between 1976 and 1977:

CPI in 1977 CPI in 1976
×
1976 GBP value
=
1977 GBP value

Then plug in historical CPI values. The U.K. CPI was 157.1 in the year 1976 and 182 in 1977:

182157.1
×
£1
=
£1.16

£1 in 1976 has the same "purchasing power" or "buying power" as £1.16 in 1977.

To get the total inflation rate for the 1 years between 1976 and 1977, we use the following formula:

CPI in 1977 - CPI in 1976CPI in 1976
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

182 - 157.1157.1
×
100
=
16%

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

• Steve Jobs and Stebe Wozniak invent the Apple Computer in Job's parents' garage.
• The US Viking 1 lands on Mars, becoming the first man-built object on the Red Planet.
• Osvaldo Dorticos Torrado is replaced as Cuban President by Fidel Castro.

## 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.
