## How to Calculate Inflation Rate for \$100, 1931 to 1991

Our calculations use the following inflation rate formula to calculate the change in value between 1931 and 1991:

CPI in 1991 CPI in 1931
×
=

Then plug in historical CPI values. The Canadian CPI was 7.9 in the year 1931 and 82.9 in 1991:

82.97.9
×
\$100
=
\$1,049.37

\$100 in 1931 has the same "purchasing power" or "buying power" as \$1,049.37 in 1991.

To get the total inflation rate for the 60 years between 1931 and 1991, we use the following formula:

CPI in 1991 - CPI in 1931CPI in 1931
×
100
=
Cumulative inflation rate (60 years)

Plugging in the values to this equation, we get:

82.9 - 7.97.9
×
100
=
949%

Politics and news often influence economic performance. Here's what was happening at the time:

• The Empire State Building opens in New York.
• A railway explosion is faked by the Japanese in order to create a pretext for their Manchuria invasion.
