How to calculate inflation rate for $100, 1920 to 2021

Our calculations use the following inflation rate formula to calculate the change in value between 1920 and 2021:

CPI in 2021 CPI in 1920
×
1920 CAD value
=
2021 CAD value

Then plug in historical CPI values. The Canadian CPI was 11.35833333 in the year 1920 and 141.6083333 in 2021:

141.608333311.35833333
×
$100
=
$1,246.74

$100 in 1920 has the same "purchasing power" or "buying power" as $1,246.74 in 2021.

To get the total inflation rate for the 101 years between 1920 and 2021, we use the following formula:

CPI in 2021 - CPI in 1920CPI in 1920
×
100
=
Cumulative inflation rate (101 years)

Plugging in the values to this equation, we get:

141.6083333 - 11.3583333311.35833333
×
100
=
1,147%
