Buying power of $1 in 1990

This chart shows a calculation of buying power equivalence for $1 in 1990 (price index tracking began in 1922).

For example, if you started with $1, you would need to end with $1.17 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $1.17 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.

How to calculate inflation rate for $1, 1990 to 1998

Our calculations use the following inflation rate formula to calculate the change in value between 1990 and 1998:

CPI in 1998 CPI in 1990
×
1990 AUD value
=
1998 AUD value

Then plug in historical CPI values. The Australian CPI was 57.5 in the year 1990 and 67.4 in 1998:

67.457.5
×
$1
=
$1.17

$1 in 1990 has the same "purchasing power" or "buying power" as $1.17 in 1998.

To get the total inflation rate for the 8 years between 1990 and 1998, we use the following formula:

CPI in 1998 - CPI in 1990CPI in 1990
×
100
=
Cumulative inflation rate (8 years)

Plugging in the values to this equation, we get:

67.4 - 57.557.5
×
100
=
17%
