How to Calculate Inflation Rate for $100, 1928 to 1981

Our calculations use the following inflation rate formula to calculate the change in value between 1928 and 1981:

CPI in 1981 CPI in 1928
×
1928 AUD value
=
1981 AUD value

Then plug in historical CPI values. The Australian CPI was 2.9 in the year 1928 and 28.9 in 1981:

28.92.9
×
$100
=
$996.55

$100 in 1928 has the same "purchasing power" or "buying power" as $996.55 in 1981.

To get the total inflation rate for the 53 years between 1928 and 1981, we use the following formula:

CPI in 1981 - CPI in 1928CPI in 1928
×
100
=
Cumulative inflation rate (53 years)

Plugging in the values to this equation, we get:

28.9 - 2.92.9
×
100
=
897%
