How to calculate inflation rate for $100, 1920 to 2009

Our calculations use the following inflation rate formula to calculate the change in value between 1920 and 2009:

CPI in 2009 CPI in 1920
×
1920 CAD value
=
2009 CAD value

Then plug in historical CPI values. The Canadian CPI was 11.35833333 in the year 1920 and 114.4333333 in 2009:

114.433333311.35833333
×
$100
=
$1,007.48

$100 in 1920 has the same "purchasing power" or "buying power" as $1,007.48 in 2009.

To get the total inflation rate for the 89 years between 1920 and 2009, we use the following formula:

CPI in 2009 - CPI in 1920CPI in 1920
×
100
=
Cumulative inflation rate (89 years)

Plugging in the values to this equation, we get:

114.4333333 - 11.3583333311.35833333
×
100
=
907%
