## Buying power of £1 in 1945

This chart shows a calculation of buying power equivalence for £1 in 1945 (price index tracking began in 1750).

For example, if you started with £1, you would need to end with £1.79 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When £1 is equivalent to £1.79 over time, that means that the "real value" of a single U.K. pound decreases over time. In other words, a pound will pay for fewer items at the store.

This effect explains how inflation erodes the value of a pound over time. By calculating the value in 1945 dollars, the chart below shows how £1 is worth less over 12 years.

According to the Office for National Statistics, each of these GBP amounts below is equal in terms of what it could buy at the time:

## How to Calculate Inflation Rate for £1, 1945 to 1957

Our calculations use the following inflation rate formula to calculate the change in value between 1945 and 1957:

CPI in 1957 CPI in 1945
×
1945 GBP value
=
1957 GBP value

Then plug in historical CPI values. The U.K. CPI was 26.2 in the year 1945 and 46.9 in 1957:

46.926.2
×
£1
=
£1.79

£1 in 1945 has the same "purchasing power" or "buying power" as £1.79 in 1957.

To get the total inflation rate for the 12 years between 1945 and 1957, we use the following formula:

CPI in 1957 - CPI in 1945CPI in 1945
×
100
=
Cumulative inflation rate (12 years)

Plugging in the values to this equation, we get:

46.9 - 26.226.2
×
100
=
79%

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

• The USSR captures Budapest from Germany in a battle that kills 159,000 people.
• The US Fleet captures Iwo Jima.
• 1,500 US Navy ships bomb Okinawa: the operation is believed to be the largest of World War II
• Iwo Jima is occupied by America, costing 6,000 American lives and a further 18,000 Japanese lives.
• Buchenwald, the first Nazi concentration camp, is liberated.

## 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.
