## Buying power of \$1 in 2018

This chart shows a calculation of buying power equivalence for \$1 in 2018 (price index tracking began in 1922).

For example, if you started with \$1, you would need to end with \$0.98 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$1 is equivalent to \$0.98 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 \$1 is worth less over 2 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, 2018 to 2020

Our calculations use the following inflation rate formula to calculate the change in value between 2018 and 2020:

CPI in 2018 CPI in 2020
×
2020 AUD value
=
2018 AUD value

Then plug in historical CPI values. The Australian CPI was 116.1 in the year 2020 and 113.3 in 2018:

113.3116.1
×
\$1
=
\$0.98

\$1 in 2020 has the same "purchasing power" or "buying power" as \$0.98 in 2018.

To get the total inflation rate for the 2 years between 2018 and 2020, we use the following formula:

CPI in 2018 - CPI in 2020CPI in 2020
×
100
=
Cumulative inflation rate (2 years)

Plugging in the values to this equation, we get:

113.3 - 116.1116.1
×
100
=
-2%
