How to Calculate Inflation Rate for $1, 1842 to 1845

Our calculations use the following inflation rate formula to calculate the change in value between 1842 and 1845:

CPI in 1842 CPI in 1845
×
1845 USD value
=
1842 USD value

Then plug in historical CPI values. The U.S. CPI was 7.6 in the year 1845 and 8.2 in 1842:

8.27.6
×
$1
=
$1.08

$1 in 1845 has the same "purchasing power" or "buying power" as $1.08 in 1842.

To get the total inflation rate for the 3 years between 1842 and 1845, we use the following formula:

CPI in 1842 - CPI in 1845CPI in 1845
×
100
=
Cumulative inflation rate (3 years)

Plugging in the values to this equation, we get:

8.2 - 7.67.6
×
100
=
8%
