## How to Calculate Inflation Rate for \$100 since 1945

Our calculations use the following inflation rate formula to calculate the change in value between 1945 and today:

CPI today CPI in 1945
×
1945 AUD value
=
Today's value

Then plug in historical CPI values. The Australian CPI was 3.2 in the year 1945 and 117.9 in 2021:

117.93.2
×
\$100
=
\$3,684.38

To get the total inflation rate for the 76 years between 1945 and 2021, we use the following formula:

CPI in 2021 - CPI in 1945CPI in 1945
×
100
=
Cumulative inflation rate (76 years)

Plugging in the values to this equation, we get:

117.9 - 3.23.2
×
100
=
3,584%
