Buying power of $1 in 1917

This chart shows a calculation of buying power equivalence for $1 in 1917 (price index tracking began in 1914).

For example, if you started with $1, you would need to end with $0.74 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $0.74 over time, that means that the "real value" of a single Canadian dollar decreases over time. In other words, a dollar will pay for fewer items at the store.

This effect explains how inflation erodes the value of a dollar over time. By calculating the value in 1917 dollars, the chart below shows how $1 is worth less over 3 years.

According to Statistics Canada, each of these CAD amounts below is equal in terms of what it could buy at the time:

How to Calculate Inflation Rate for $1, 1917 to 1920

Our calculations use the following inflation rate formula to calculate the change in value between 1917 and 1920:

CPI in 1917 CPI in 1920
×
1920 CAD value
=
1917 CAD value

Then plug in historical CPI values. The Canadian CPI was 11.2 in the year 1920 and 8.3 in 1917:

8.311.2
×
$1
=
$0.74

$1 in 1920 has the same "purchasing power" or "buying power" as $0.74 in 1917.

To get the total inflation rate for the 3 years between 1917 and 1920, we use the following formula:

CPI in 1917 - CPI in 1920CPI in 1920
×
100
=
Cumulative inflation rate (3 years)

Plugging in the values to this equation, we get:

8.3 - 11.211.2
×
100
=
-26%
