How to Calculate Inflation Rate for $1, 1645 to 1647

This inflation calculator uses the following inflation rate formula:

CPI in 1647CPI in 1645
×
1645 USD value
=
1647 USD value

Then plug in historical CPI values. The U.S. CPI was 8.8 in the year 1645 and 4.1 in 1647:

4.18.8
×
$1
=
$0.47

$1 in 1645 has the same "purchasing power" or "buying power" as $0.47 in 1647.

To get the total inflation rate for the 2 years between 1645 and 1647, we use the following formula:

CPI in 1647 - CPI in 1645CPI in 1645
×
100
=
Cumulative inflation rate (2 years)

Plugging in the values to this equation, we get:

4.1 - 8.88.8
×
100
=
-53%

Data Source & Citation

Raw data for these calculations comes from the Bureau of Labor Statistics' (CPI), established in 1913. Inflation data from 1665 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University.
