For example, if you started with $100, you would need to end with $158.04 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $100 is equivalent to $158.04 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 2001 dollars, the chart below shows how $100 is worth less over 20 years.
