How to Calculate Inflation Rate for $100, 1928 to 2012

Our calculations use the following inflation rate formula to calculate the change in value between 1928 and 2012:

CPI in 2012 CPI in 1928
×
1928 AUD value
=
2012 AUD value

Then plug in historical CPI values. The Australian CPI was 2.9 in the year 1928 and 101 in 2012:

1012.9
×
$100
=
$3,482.76

$100 in 1928 has the same "purchasing power" or "buying power" as $3,482.76 in 2012.

To get the total inflation rate for the 84 years between 1928 and 2012, we use the following formula:

CPI in 2012 - CPI in 1928CPI in 1928
×
100
=
Cumulative inflation rate (84 years)

Plugging in the values to this equation, we get:

101 - 2.92.9
×
100
=
3,383%
