How to calculate inflation rate for $1, 2004 to 2005
Our calculations use the following inflation rate formula to calculate the change in value between 2004 and 2005:
CPI in 2005 CPI in 2004
×
2004 AUD value
=
2005 AUD value
Then plug in historical CPI values. The Australian CPI was 80.8 in the year 2004 and 83 in 2005:
8380.8
×
$1
=
$1.03
$1 in 2004 has the same "purchasing power" or "buying power" as $1.03 in 2005.
To get the total inflation rate for the 1 years between 2004 and 2005, we use the following formula:
CPI in 2005 - CPI in 2004CPI in 2004
×
100
=
Cumulative inflation rate (1 years)
Plugging in the values to this equation, we get:
83 - 80.880.8
×

=
3%
