## Why a dollar today is worth only 26% of a dollar in 1977

Updated: September 11, 2020

According to Statistics Canada consumer price index, today's prices in 2020 are 290.83% higher than average prices since 1977. This means that a dollar today only buys 25.59% of what it could buy in 1977. The Canadian dollar experienced an average inflation rate of 3.22% per year during this period, causing the real value of a dollar to decrease.

In other words, \$100 in 1977 is equivalent in purchasing power to about \$390.83 in 2020, a difference of \$290.83 over 43 years.

The 1977 inflation rate was 9.40%. 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 1977

This chart shows a calculation of buying power equivalence for \$100 in 1977 (price index tracking began in 1914).

For example, if you started with \$100, you would need to end with \$390.83 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$100 is equivalent to \$390.83 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 1977 dollars, the chart below shows how \$100 is worth less over 43 years.

## How to Calculate Inflation Rate for \$100 since 1977

Our calculations use the following inflation rate formula to calculate the change in value between 1977 and today:

CPI today CPI in 1977
×
=
Today's value

Then plug in historical CPI values. The Canadian CPI was 34.9 in the year 1977 and 136.4 in 2020:

136.434.9
×
\$100
=
\$390.83

\$100 in 1977 has the same "purchasing power" or "buying power" as \$390.83 in 2020.

To get the total inflation rate for the 43 years between 1977 and 2020, we use the following formula:

CPI in 2020 - CPI in 1977CPI in 1977
×
100
=
Cumulative inflation rate (43 years)

Plugging in the values to this equation, we get:

136.4 - 34.934.9
×
100
=
291%

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

• Apple Computer incorperated by Steve Jobs, Steve Wozniak, and Ronald Wayne.
