This chart shows a calculation of buying power equivalence for $100 in 2018 (price index tracking began in 1922).

For example, if you started with $100, you would need to end with $104.06 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $100 is equivalent to $104.06 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 2018 dollars, the chart below shows how $100 is worth less over 3 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:

$100 in 2018 has the same "purchasing power" or "buying power" as $104.06 in 2021.

To get the total inflation rate for the 3 years between 2018 and 2021, we use the following formula:

CPI in 2021 - CPI in 2018CPI in 2018
