Buying power of $1 in 2005

This chart shows a calculation of buying power equivalence for $1 in 2005 (price index tracking began in 1922).

For example, if you started with $1, you would need to end with $1.13 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $1.13 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 2005 dollars, the chart below shows how $1 is worth less over 4 years.

How to Calculate Inflation Rate for $1, 2005 to 2009

Our calculations use the following inflation rate formula to calculate the change in value between 2005 and 2009:

CPI in 2009 CPI in 2005
×
2005 AUD value
=
2009 AUD value

Then plug in historical CPI values. The Australian CPI was 83 in the year 2005 and 93.4 in 2009:

93.483
×
$1
=
$1.13

$1 in 2005 has the same "purchasing power" or "buying power" as $1.13 in 2009.

To get the total inflation rate for the 4 years between 2005 and 2009, we use the following formula:

CPI in 2009 - CPI in 2005CPI in 2005
×
100
=
Cumulative inflation rate (4 years)

Plugging in the values to this equation, we get:

93.4 - 8383
×
100
=
13%
