Buying power of $1 in 2015

This chart shows a calculation of buying power equivalence for $1 in 2015 (price index tracking began in 1922).

For example, if you started with $1, you would need to end with $1.11 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $1.11 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 2015 dollars, the chart below shows how $1 is worth less over 6 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:

How to calculate inflation rate for $1, 2015 to 2021

Our calculations use the following inflation rate formula to calculate the change in value between 2015 and 2021:

CPI in 2021 CPI in 2015
×
2015 AUD value
=
2021 AUD value

Then plug in historical CPI values. The Australian CPI was 107.7 in the year 2015 and 119.4 in 2021:

119.4107.7
×
$1
=
$1.11

$1 in 2015 has the same "purchasing power" or "buying power" as $1.11 in 2021.

To get the total inflation rate for the 6 years between 2015 and 2021, we use the following formula:

CPI in 2021 - CPI in 2015CPI in 2015
×
100
=
Cumulative inflation rate (6 years)

Plugging in the values to this equation, we get:

119.4 - 107.7107.7
×
100
=
11%
