## How to Calculate Inflation Rate for \$100, 1920 to 1981

Our calculations use the following inflation rate formula to calculate the change in value between 1920 and 1981:

CPI in 1981 CPI in 1920
×
=

Then plug in historical CPI values. The Canadian CPI was 11.2 in the year 1920 and 51.8 in 1981:

51.811.2
×
\$100
=
\$462.50

\$100 in 1920 has the same "purchasing power" or "buying power" as \$462.50 in 1981.

To get the total inflation rate for the 61 years between 1920 and 1981, we use the following formula:

CPI in 1981 - CPI in 1920CPI in 1920
×
100
=
Cumulative inflation rate (61 years)

Plugging in the values to this equation, we get:

51.8 - 11.211.2
×
100
=
363%

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

• The League of Nations' first assembly takes place in Paris.
• The British Parliament passes the Fourth Home Rule Act, dividing Ireland into two parts and leading to a yearlong Anglo-Irish war in the southern counties.
• The Catholic Church canonizes Joan of Arc, formally making her a saint.
• The 19th Amendment to the constitution is ratified, granting U.S. woman suffrage for the first time.
