## Buying power of £1 in 1797

This chart shows a calculation of buying power equivalence for £1 in 1797 (price index tracking began in 1750).

For example, if you started with £1, you would need to end with £0.67 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When £1 is equivalent to £0.67 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 1797 dollars, the chart below shows how £1 is worth less over 3 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, 1797 to 1800

Our calculations use the following inflation rate formula to calculate the change in value between 1797 and 1800:

CPI in 1797 CPI in 1800
×
1800 GBP value
=
1797 GBP value

Then plug in historical CPI values. The U.K. CPI was 13.5 in the year 1800 and 9 in 1797:

913.5
×
£1
=
£0.67

£1 in 1800 has the same "purchasing power" or "buying power" as £0.67 in 1797.

To get the total inflation rate for the 3 years between 1797 and 1800, we use the following formula:

CPI in 1797 - CPI in 1800CPI in 1800
×
100
=
Cumulative inflation rate (3 years)

Plugging in the values to this equation, we get:

9 - 13.513.5
×
100
=
-33%

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

• The free African American community of Philadelphia submits its first petition to US Congress for the abolition of slavery.
• Barnaba Niccoclo Maria Luigi Chiaramonti elected pope, taking the name Pope Pius VII.
• A Smallpox vaccine is invented by Doctor Benjamin Waterhouse leading to the first immunization against the disease.
• Congress holds its first session in the, at the time, still incomplete Capitol building in Washington D.C.
• The French army defeats the Turks at Helipolis, after which they advanced on to Cairo.

## 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.
