1642 USD value

Then plug in historical CPI values. The U.S. CPI was 8.8 in the year 1645 and 9.6 in 1642:

9.68.8
×
$1
=
$1.09

$1 in 1645 has the same "purchasing power" or "buying power" as $1.09 in 1642.

To get the total inflation rate for the 3 years between 1642 and 1645, we use the following formula:

CPI in 1642 - CPI in 1645CPI in 1645
×
100
=
Cumulative inflation rate (3 years)

Plugging in the values to this equation, we get:

9.6 - 8.88.8
×
100
=
9%
