Then plug in historical CPI values. The Australian CPI was 2.7 in the year 1940 and 32.1 in 1982:

32.12.7
×
$100
=
$1,188.89

To get the total inflation rate for the 42 years between 1940 and 1982, we use the following formula:

CPI in 1982 - CPI in 1940CPI in 1940
×
100
=
Cumulative inflation rate (42 years)

Plugging in the values to this equation, we get:

32.1 - 2.72.7
×
100
=
1,089%
