How to calculate inflation rate for $100, 1930 to 2021

Our calculations use the following inflation rate formula to calculate the change in value between 1930 and 2021:

CPI in 2021 CPI in 1930
×
1930 AUD value
=
2021 AUD value

Then plug in historical CPI values. The Australian CPI was 2.7 in the year 1930 and 118.8 in 2021:

118.82.7
×
$100
=
$4,400.00

$100 in 1930 has the same "purchasing power" or "buying power" as $4,400.00 in 2021.

To get the total inflation rate for the 91 years between 1930 and 2021, we use the following formula:

CPI in 2021 - CPI in 1930CPI in 1930
×
100
=
Cumulative inflation rate (91 years)

Plugging in the values to this equation, we get:

118.8 - 2.72.7
×
100
=
4,300%
