### How to Calculate Inflation Rate for \$100, 1927 to 1991

This inflation calculator uses the following inflation rate formula:

CPI in 1991CPI in 1927
×
1927 AUD value
=
1991 AUD value

Then plug in historical CPI values. The Australian CPI was 2.8 in the year 1927 and 59.3 in 1991:

59.32.8
×
\$100
=
\$2,117.86

\$100 in 1927 has the same "purchasing power" or "buying power" as \$2,117.86 in 1991.

To get the total inflation rate for the 64 years between 1927 and 1991, we use the following formula:

CPI in 1991 - CPI in 1927CPI in 1927
×
100
=
Cumulative inflation rate (64 years)

Plugging in the values to this equation, we get:

59.3 - 2.82.8
×
100
=
2,018%

Politics and news often influence economic performance. Here's what was happening at the time:

• The counter revolution begins in Shanghai by Kuomintang leader Chiang Kai-shek.
