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.

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