### Inflation in 1816 and Its Effect on Pound Value

Purchasing power increased by 8.66% in 1816 compared to 1815. On average, you would have to spend 8.66% less money in 1816 than in 1815 for the same item. This is an example of deflation.

In other words, £1 in 1815 is equivalent in purchasing power to about £0.91 in 1816.

The 1815 inflation rate was -10.56%. The inflation rate in 1816 was -8.66%. The 1816 inflation rate is lower compared to the average inflation rate of 2.27% per year between 1816 and 2020.

Inflation rate is calculated by change in the composite price index (CPI). The CPI in 1816 was 11.60. It was 12.70 in the previous year, 1815. The difference in CPI between the years is used by the Office for National Statistics to officially determine inflation. Because the 1816 CPI is less than 1815 CPI, negative inflation (also known as deflation) has occurred.

### How to Calculate Inflation Rate for £1, 1815 to 1816

This inflation calculator uses the following inflation rate formula:

CPI in 1816CPI in 1815
×
1815 GBP value
=
1816 GBP value

Then plug in historical CPI values. The U.K. CPI was 12.7 in the year 1815 and 11.6 in 1816:

11.612.7
×
£1
=
£0.91

£1 in 1815 has the same "purchasing power" or "buying power" as £0.91 in 1816.

To get the total inflation rate for the 1 years between 1815 and 1816, we use the following formula:

CPI in 1816 - CPI in 1815CPI in 1815
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

11.6 - 12.712.7

=
-9%

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

• Napoleon leaves Elba in order to reconnect with his supporters in France.
• Napoleon returns to Paris and begins his 100-day rule until his defeat in the Battle of Waterloo.
• The Holy Alliance is signed by Russia, Prussia and Austria
• Napoleon Bonaparte arrives on the island of Saint Hellena to begin his exile

### 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.
