Inflation in 1802 and Its Effect on Dollar Value

Purchasing power increased by 15.75% in 1802 compared to the previous year, 1801. On average, you would have to spend 15.75% less money in 1802 than in 1801 for the same item. This is an example of deflation.

In other words, $100 in 1801 is equivalent in purchasing power to $84.25 in 1802.

The 1801 inflation rate was 0.79%. The inflation rate in 1802 was -15.75%. The 1802 inflation rate is lower compared to the average inflation rate of 1.47% per year between 1802 and 2018.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1802 was 10.7. It was 12.7 in the previous year, 1801. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1802 CPI is less than 1801 CPI, negative inflation (also known as deflation) has occurred.

Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £100.00 in 1801 would be equivalent to £76.82 in 1802, an absolute change of £-23.18 and a cumulative change of -23.18%.

Compare these numbers to the US's overall absolute change of $-15.75 and total percent change of -15.75%.


Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. This chart shows the average rate of inflation for select CPI categories between 1801 and 1802.

Compare these values to the overall average of -15.748031496062998% per year:

How to Calculate Inflation Rate for $100, 1801 to 1802

This inflation calculator uses the following inflation rate formula:

CPI in 1802CPI in 1801
×
1801 USD value
=
1802 USD value

Then plug in historical CPI values. The U.S. CPI was 12.7 in the year 1801 and 10.7 in 1802:

10.712.7
×
$100
=
$84.25

$100 in 1801 has the same "purchasing power" or "buying power" as $84.25 in 1802.

To get the total inflation rate for the 1 years between 1801 and 1802, we use the following formula:

CPI in 1802 - CPI in 1801CPI in 1801
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

10.7 - 12.712.7

=
-16%
