The composite price index (CPI) in 1970 was 73.1. It was 68.7 in the previous year. This change in CPI is used by the Office for National Statistics to calculate inflation.

According to the Office for National Statistics composite price index, the pound experienced an average inflation rate of 5.81% per year. Prices in 2018 are 1,402.42% higher than prices in 1970.

In other words, £100 in 1970 is equivalent in purchasing power to £1,502.42 in 2018, a difference of £1,402.42 over 48 years.

The current inflation rate is now 2.20%^{1}. If this number holds, £100 today will be equivalent to £102.20 next year.

This inflation calculator uses the following inflation rate formula:

CPI in 2018 / CPI in 1970 * 1970 GBP value = 2018 GBP value

Then plug in historical CPI values. The UK CPI was 73.1 in the year 1970 and 1098.27186 in 2018:

1098.27186 / 73.1 * £100 = **£1,502.42**

£100 in 1970 has the same "purchasing power" or "buying power" as £1,502.42 in 2018.

This chart shows calculations of buying power equivalence over time for £100 in 1970 (price index tracking began in 1750).

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

- 1/1/1970 established as Epoch time for UNIX systems.
- Rhodesia declares independence and sets up a republican government.
- Aswan Dam opens in Egypt to prevent flooding of the Nile River.
- A Palestinian terrorist organization, hijacks three aircraft, in an incident that is later known as Black September.

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.
