How to Calculate Inflation Rate for $1, 1690 to 1691
Our calculations use the following inflation rate formula to calculate the change in value between 1690 and 1691:
CPI in 1691
CPI in 1690
×
1690 USD value
=
1691 USD value
Then plug in historical CPI values. The U.S. CPI was 3.7 in the year 1690 and 3.9 in 1691:
3.93.7
×
$1
=
$1.05
$1 in 1690 has the same "purchasing power" or "buying power" as $1.05 in 1691.
To get the total inflation rate for the 1 years between 1690 and 1691, we use the following formula:
CPI in 1691 - CPI in 1690CPI in 1690
×
100
=
Cumulative inflation rate (1 years)
Plugging in the values to this equation, we get:
3.9 - 3.73.7
×
