How to calculate inflation rate for $100, 1805 to 1912

Our calculations use the following inflation rate formula to calculate the change in value between 1805 and 1912:

CPI in 1912 CPI in 1805
×
1805 USD value
=
1912 USD value

Then plug in historical CPI values. The U.S. CPI was 11.7 in the year 1805 and 9.7 in 1912:

9.711.7
×
$100
=
$82.91

$100 in 1805 has the same "purchasing power" or "buying power" as $82.91 in 1912.

To get the total inflation rate for the 107 years between 1805 and 1912, we use the following formula:

CPI in 1912 - CPI in 1805CPI in 1805
×
100
=
Cumulative inflation rate (107 years)

Plugging in the values to this equation, we get:

9.7 - 11.711.7
×
100
=
-17%
