# UK inflation rate in 1842: -8.26%

### Inflation in 1842 and Its Effect on Pound Value

Purchasing power increased by 8.26% in 1842 compared to 1841. On average, you would have to spend 8.26% less money in 1842 than in 1841 for the same item. This is an example of deflation.

In other words, £1 in 1841 is equivalent in purchasing power to about £0.92 in 1842.

The 1841 inflation rate was -1.80%. The inflation rate in 1842 was -8.26%. The 1842 inflation rate is lower compared to the average inflation rate of 2.70% per year between 1842 and 2019.

Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1842 was 10.00. It was 10.90 in the previous year, 1841. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation. Because the 1842 CPI is less than 1841 CPI, negative inflation (also known as deflation) has occurred.

### How to Calculate Inflation Rate for £1, 1841 to 1842

This inflation calculator uses the following inflation rate formula:

CPI in 1842CPI in 1841
×
1841 GBP value
=
1842 GBP value

Then plug in historical CPI values. The UK CPI was 10.9 in the year 1841 and 10 in 1842:

1010.9
×
£1
=
£0.92

£1 in 1841 has the same "purchasing power" or "buying power" as £0.92 in 1842.

To get the total inflation rate for the 1 years between 1841 and 1842, we use the following formula:

CPI in 1842 - CPI in 1841CPI in 1841
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

10 - 10.910.9
×

=
-8%

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

• The British gain control over Hong Kong during the First Opium War, after China conceded it to them.
• The first emigrant wagon train departs, heading from Independence, Missouri, to California.
• The first wagon train arrives in California.

### 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.
