How to Calculate Inflation Rate for \$100, 1930 to 2011

This inflation calculator uses the following inflation rate formula:

CPI in 2011CPI in 1930
×
1930 AUD value
=
2011 AUD value

Then plug in historical CPI values. The Australian CPI was 2.7 in the year 1930 and 99.3 in 2011:

99.32.7
×
\$100
=
\$3,677.78

\$100 in 1930 has the same "purchasing power" or "buying power" as \$3,677.78 in 2011.

To get the total inflation rate for the 81 years between 1930 and 2011, we use the following formula:

CPI in 2011 - CPI in 1930CPI in 1930
×
100
=
Cumulative inflation rate (81 years)

Plugging in the values to this equation, we get:

99.3 - 2.72.7
×
100
=
3,578%
