### Buying power of £1 in 1905

This chart shows a calculation of buying power equivalence for £1 in 1905 (price index tracking began in 1750).

For example, if you started with £1, you would need to end with £1.75 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When £1 is equivalent to £1.75 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 1905 dollars, the chart below shows how £1 buys less over the past 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, 1905 to 1917

This inflation calculator uses the following inflation rate formula:

CPI in 1917CPI in 1905
×
1905 GBP value
=
1917 GBP value

Then plug in historical CPI values. The U.K. CPI was 9.3 in the year 1905 and 16.3 in 1917:

16.39.3
×
£1
=
£1.75

£1 in 1905 has the same "purchasing power" or "buying power" as £1.75 in 1917.

To get the total inflation rate for the 12 years between 1905 and 1917, we use the following formula:

CPI in 1917 - CPI in 1905CPI in 1905
×
100
=
Cumulative inflation rate (12 years)

Plugging in the values to this equation, we get:

16.3 - 9.39.3
×
100
=
75%

### News headlines from 1905

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

• The Industrial Workers of the World is formed. It is an American anarcho-syndicalist union.
• Bloody Sunday in Russia: troops fire and kill protesters, mostly workers, marching to the Winter Palace in order to hand a petition to the Tsar.
• Potemkin's arrival at Odessa leads to sailors joining civilians in the '1905 Revolution’.

### 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.
