## How to calculate inflation rate for \$1, 1647 to 1648

Our calculations use the following inflation rate formula to calculate the change in value between 1647 and 1648:

CPI in 1648 CPI in 1647
×
1647 USD value
=
1648 USD value

Then plug in historical CPI values. The U.S. CPI was 4.1 in the year 1647 and 7.3 in 1648:

7.34.1
×
\$1
=
\$1.78

\$1 in 1647 has the same "purchasing power" or "buying power" as \$1.78 in 1648.

CPI in 1648 - CPI in 1647CPI in 1647
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

7.3 - 4.14.1
