Buying power of $1 in 1990

This chart shows a calculation of buying power equivalence for $1 in 1990 (price index tracking began in 1914).

For example, if you started with $1, you would need to end with $2.05 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $2.05 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 1990 dollars, the chart below shows how $1 is worth less over 34 years.

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

This conversion table shows various other 1990 amounts in 2024 dollars, based on the 105.24% change in prices:

How to calculate inflation rate for $1, 1990 to 2024

Our calculations use the following inflation rate formula to calculate the change in value between 1990 and 2024:

Then plug in historical CPI values. The Canadian CPI was 78.35833333 in the year 1990 and 160.82 in 2024:

$1 in 1990 has the same "purchasing power" or "buying power" as $2.05 in 2024.

To get the total inflation rate for the 34 years between 1990 and 2024, we use the following formula:

Plugging in the values to this equation, we get:
