Updated: November 12, 2020

According to Statistics Canada consumer price index, today's prices in 2020 are 4.28% higher than average prices since 2018. This means that a dollar today only buys 95.90% of what it could buy in 2018. The Canadian dollar experienced an average inflation rate of 2.12% per year during this period, causing the real value of a dollar to decrease.

In other words, $100 in 2018 is equivalent in purchasing power to about $104.28 in 2020, a difference of $4.28 over 2 years.

The 2018 inflation rate was 0.31%. The current year-over-year inflation rate (2019 to 2020) is now 2.25%1. If this number holds, $100 today will be equivalent in buying power to $102.25 next year.

Buying power of $100 in 2018

This chart shows a calculation of buying power equivalence for $100 in 2018 (price index tracking began in 1914).

For example, if you started with $100, you would need to end with $104.28 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $100 is equivalent to $104.28 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.

How to Calculate Inflation Rate for $100 since 2018

Our calculations use the following inflation rate formula to calculate the change in value between 2018 and today:

CPI today CPI in 2018
×
2018 CAD value
=
Today's value

Then plug in historical CPI values. The Canadian CPI was 130.8 in the year 2018 and 136.4 in 2020:

136.4130.8
×
$100
=
$104.28

$100 in 2018 has the same "purchasing power" or "buying power" as $104.28 in 2020.

To get the total inflation rate for the 2 years between 2018 and 2020, we use the following formula:

CPI in 2020 - CPI in 2018CPI in 2018
×
100
=
Cumulative inflation rate (2 years)

Plugging in the values to this equation, we get:

136.4 - 130.8130.8
×
100
=
4%
