How to calculate inflation rate for $1, 1785 to 1791

Our calculations use the following inflation rate formula to calculate the change in value between 1785 and 1791:

CPI in 1791 CPI in 1785
×
1785 USD value
=
1791 USD value

Then plug in historical CPI values. The U.S. CPI was 9.7 in the year 1785 and 9.4 in 1791:

9.49.7
×
$1
=
$0.97

$1 in 1785 has the same "purchasing power" or "buying power" as $0.97 in 1791.

To get the total inflation rate for the 6 years between 1785 and 1791, we use the following formula:

CPI in 1791 - CPI in 1785CPI in 1785
×
100
=
Cumulative inflation rate (6 years)

Plugging in the values to this equation, we get:

9.4 - 9.79.7
×
100
=
-3%
