Inflation in 1807 and Its Effect on Dollar Value

Purchasing power increased by 4.92% in 1807 compared to the previous year, 1806. On average, you would have to spend 4.92% less money in 1807 than in 1806 for the same item. This is an example of deflation.

In other words, $100 in 1806 is equivalent in purchasing power to $95.08 in 1807.

The 1806 inflation rate was 4.27%. The inflation rate in 1807 was -4.92%. The 1807 inflation rate is lower compared to the average inflation rate of 1.47% per year between 1807 and 2018.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1807 was 11.6. It was 12.2 in the previous year, 1806. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1807 CPI is less than 1806 CPI, negative inflation (also known as deflation) has occurred.

Compare these numbers to the US's overall absolute change of $-4.92 and total percent change of -4.92%.


Inflation by Spending Category

How to Calculate Inflation Rate for $100, 1806 to 1807

This inflation calculator uses the following inflation rate formula:

CPI in 1807CPI in 1806
×
1806 USD value
=
1807 USD value

Then plug in historical CPI values. The U.S. CPI was 12.2 in the year 1806 and 11.6 in 1807:

11.612.2
×
$100
=
$95.08

$100 in 1806 has the same "purchasing power" or "buying power" as $95.08 in 1807.

To get the total inflation rate for the 1 years between 1806 and 1807, we use the following formula:

CPI in 1807 - CPI in 1806CPI in 1806
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

11.6 - 12.212.2
