### How to Calculate Inflation Rate for £1, 1840 to 1843

This inflation calculator uses the following inflation rate formula:

CPI in 1843CPI in 1840
×
1840 GBP value
=
1843 GBP value

Then plug in historical CPI values. The U.K. CPI was 11.1 in the year 1840 and 8.9 in 1843:

8.911.1
×
£1
=
£0.80

£1 in 1840 has the same "purchasing power" or "buying power" as £0.80 in 1843.

To get the total inflation rate for the 3 years between 1840 and 1843, we use the following formula:

CPI in 1843 - CPI in 1840CPI in 1840
×
100
=
Cumulative inflation rate (3 years)

Plugging in the values to this equation, we get:

8.9 - 11.111.1
×
100
=
-20%

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

• Identification of Antarctica as a new continent by American naval expedition lead by Charles Wilkes.
• Charles Wilkes discovers Antarctica in an American naval expedition.
• Charles Wilkes discovers the Shackleton Ice Shelf in Antarctica.
• The world’s first postage stamp, the Penny Black, is released.
• Samuel Morse patents the telegraph.

### 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.
