How to Calculate Inflation Rate for $1, 1684 to 1685

Our calculations use the following inflation rate formula to calculate the change in value between 1684 and 1685:

CPI in 1684 CPI in 1685
×
1685 USD value
=
1684 USD value

Then plug in historical CPI values. The U.S. CPI was 4.1 in the year 1685 and 3.7 in 1684:

3.74.1
×
$1
=
$0.90

$1 in 1685 has the same "purchasing power" or "buying power" as $0.90 in 1684.

To get the total inflation rate for the 1 years between 1684 and 1685, we use the following formula:

CPI in 1684 - CPI in 1685CPI in 1685
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

3.7 - 4.14.1
×
