How to Calculate Inflation Rate for $1, 1815 to 1820

Our calculations use the following inflation rate formula to calculate the change in value between 1815 and 1820:

CPI in 1820 CPI in 1815
×
1815 USD value
=
1820 USD value

Then plug in historical CPI values. The U.S. CPI was 15.4 in the year 1815 and 11.7 in 1820:

11.715.4
×
$1
=
$0.76

$1 in 1815 has the same "purchasing power" or "buying power" as $0.76 in 1820.

To get the total inflation rate for the 5 years between 1815 and 1820, we use the following formula:

CPI in 1820 - CPI in 1815CPI in 1815
×
100
=
Cumulative inflation rate (5 years)

Plugging in the values to this equation, we get:

11.7 - 15.415.4
×
100
=
-24%
