Buying power of $1 in 1987

This chart shows a calculation of buying power equivalence for $1 in 1987 (price index tracking began in 1922).

For example, if you started with $1, you would need to end with $0.81 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $0.81 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 1987 dollars, the chart below shows how $1 is worth less over 3 years.

How to calculate inflation rate for $1, 1987 to 1990

Our calculations use the following inflation rate formula to calculate the change in value between 1987 and 1990:

CPI in 1987 CPI in 1990
×
1990 AUD value
=
1987 AUD value

Then plug in historical CPI values. The Australian CPI was 57.5 in the year 1990 and 46.4 in 1987:

46.457.5
×
$1
=
$0.81

$1 in 1990 has the same "purchasing power" or "buying power" as $0.81 in 1987.

To get the total inflation rate for the 3 years between 1987 and 1990, we use the following formula:

CPI in 1987 - CPI in 1990CPI in 1990
×
100
=
Cumulative inflation rate (3 years)

Plugging in the values to this equation, we get:

46.4 - 57.557.5
×
100
=
-19%
