## How to Calculate Inflation Rate for \$100, 1931 to 2017

Our calculations use the following inflation rate formula to calculate the change in value between 1931 and 2017:

CPI in 2017 CPI in 1931
×
1931 AUD value
=
2017 AUD value

Then plug in historical CPI values. The Australian CPI was 2.5 in the year 1931 and 111.2 in 2017:

111.22.5
×
\$100
=
\$4,448

\$100 in 1931 has the same "purchasing power" or "buying power" as \$4,448 in 2017.

To get the total inflation rate for the 86 years between 1931 and 2017, we use the following formula:

CPI in 2017 - CPI in 1931CPI in 1931
×
100
=
Cumulative inflation rate (86 years)

Plugging in the values to this equation, we get:

111.2 - 2.52.5
×
100
=
4,348%

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

• The Empire State Building opens in New York.
• A railway explosion is faked by the Japanese in order to create a pretext for their Manchuria invasion.
• Proclamation of the Chinese People's Republic by Mao Zedong.
