Buying power of $1 in 1981

This chart shows a calculation of buying power equivalence for $1 in 1981 (price index tracking began in 1922).

For example, if you started with $1, you would need to end with $0.74 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $0.74 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 1981 dollars, the chart below shows how $1 is worth less over 4 years.

How to Calculate Inflation Rate for $1, 1981 to 1985

Our calculations use the following inflation rate formula to calculate the change in value between 1981 and 1985:

CPI in 1981 CPI in 1985
×
1985 AUD value
=
1981 AUD value

Then plug in historical CPI values. The Australian CPI was 39.2 in the year 1985 and 28.9 in 1981:

28.939.2
×
$1
=
$0.74

$1 in 1985 has the same "purchasing power" or "buying power" as $0.74 in 1981.

To get the total inflation rate for the 4 years between 1981 and 1985, we use the following formula:

CPI in 1981 - CPI in 1985CPI in 1985
×
100
=
Cumulative inflation rate (4 years)

Plugging in the values to this equation, we get:

28.9 - 39.239.2
×
100
=
-26%
