### How to Calculate Inflation Rate for \$1, 1807 to 1808

This inflation calculator uses the following inflation rate formula:

CPI in 1808CPI in 1807
×
1807 USD value
=
1808 USD value

Then plug in historical CPI values. The U.S. CPI was 11.6 in the year 1807 and 12.6 in 1808:

12.611.6
×
\$1
=
\$1.09

\$1 in 1807 has the same "purchasing power" or "buying power" as \$1.09 in 1808.

To get the total inflation rate for the 1 years between 1807 and 1808, we use the following formula:

CPI in 1808 - CPI in 1807CPI in 1807
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

12.6 - 11.611.6
