How to calculate inflation rate for $100, 1925 to 1981

Our calculations use the following inflation rate formula to calculate the change in value between 1925 and 1981:

CPI in 1981 CPI in 1925
×
1925 CAD value
=
1981 CAD value

Then plug in historical CPI values. The Canadian CPI was 9.133333333 in the year 1925 and 49.525 in 1981:

49.5259.133333333
×
$100
=
$542.24

$100 in 1925 has the same "purchasing power" or "buying power" as $542.24 in 1981.

To get the total inflation rate for the 56 years between 1925 and 1981, we use the following formula:

CPI in 1981 - CPI in 1925CPI in 1925
×
100
=
Cumulative inflation rate (56 years)

Plugging in the values to this equation, we get:

49.525 - 9.1333333339.133333333
×
100
=
442%
