## How to Calculate Inflation Rate for \$100 since 1970

Our calculations use the following inflation rate formula to calculate the change in value between 1970 and today:

CPI today CPI in 1970
×
=
Today's value

Then plug in historical CPI values. The Canadian CPI was 20.3 in the year 1970 and 137.4 in 2021:

137.420.3
×
\$100
=
\$676.85

\$100 in 1970 has the same "purchasing power" or "buying power" as \$676.85 in 2021.

To get the total inflation rate for the 51 years between 1970 and 2021, we use the following formula:

CPI in 2021 - CPI in 1970CPI in 1970
×
100
=
Cumulative inflation rate (51 years)

Plugging in the values to this equation, we get:

137.4 - 20.320.3
×
100
=
577%
