How to calculate inflation rate for $100, 1918 to 2003

Our calculations use the following inflation rate formula to calculate the change in value between 1918 and 2003:

CPI in 2003 CPI in 1918
×
1918 CAD value
=
2003 CAD value

Then plug in historical CPI values. The Canadian CPI was 8.916666667 in the year 1918 and 102.75 in 2003:

102.758.916666667
×
$100
=
$1,152.34

$100 in 1918 has the same "purchasing power" or "buying power" as $1,152.34 in 2003.

To get the total inflation rate for the 85 years between 1918 and 2003, we use the following formula:

CPI in 2003 - CPI in 1918CPI in 1918
×
100
=
Cumulative inflation rate (85 years)

Plugging in the values to this equation, we get:

102.75 - 8.9166666678.916666667
×
100
=
1,052%
