Buying power of \$100 in 1980

This chart shows a calculation of buying power equivalence for \$100 in 1980 (price index tracking began in 1922).

For example, if you started with \$100, you would need to end with \$450 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$100 is equivalent to \$450 over time, that means that the "real value" of a single Australian 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 1980 dollars, the chart below shows how \$100 is worth less over 41 years.

How to Calculate Inflation Rate for \$100, 1980 to 2021

Our calculations use the following inflation rate formula to calculate the change in value between 1980 and 2021:

CPI in 2021 CPI in 1980
×
1980 AUD value
=
2021 AUD value

Then plug in historical CPI values. The Australian CPI was 26.4 in the year 1980 and 118.8 in 2021:

118.826.4
×
\$100
=
\$450

\$100 in 1980 has the same "purchasing power" or "buying power" as \$450 in 2021.

To get the total inflation rate for the 41 years between 1980 and 2021, we use the following formula:

CPI in 2021 - CPI in 1980CPI in 1980
×
100
=
Cumulative inflation rate (41 years)

Plugging in the values to this equation, we get:

118.8 - 26.426.4
×
100
=
350%
