### Buying power of \$100 in 2003

This chart shows a calculation of buying power equivalence for \$100 in 2003 (price index tracking began in 1922).

For example, if you started with \$100, you would need to end with \$148.00 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$100 is equivalent to \$148.00 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 2003 dollars, the chart below shows how \$100 buys less over the past 17 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:

To get the total inflation rate for the 17 years between 2003 and 2020, we use the following formula:

CPI in 2020 - CPI in 2003CPI in 2003
×
100
=
Cumulative inflation rate (17 years)

Plugging in the values to this equation, we get:
