How to Calculate Inflation Rate for \$100, 1921 to 1991

Our calculations use the following inflation rate formula to calculate the change in value between 1921 and 1991:

CPI in 1991 CPI in 1921
×
=

Then plug in historical CPI values. The Canadian CPI was 9.4 in the year 1921 and 82.9 in 1991:

82.99.4
×
\$100
=
\$881.91

\$100 in 1921 has the same "purchasing power" or "buying power" as \$881.91 in 1991.

To get the total inflation rate for the 70 years between 1921 and 1991, we use the following formula:

CPI in 1991 - CPI in 1921CPI in 1921
×
100
=
Cumulative inflation rate (70 years)

Plugging in the values to this equation, we get:

82.9 - 9.49.4
×
100
=
782%
