## How to Calculate Inflation Rate for \$100 since 1955

Our calculations use the following inflation rate formula to calculate the change in value between 1955 and today:

CPI today CPI in 1955
×
1955 AUD value
=
Today's value

Then plug in historical CPI values. The Australian CPI was 6.6 in the year 1955 and 117.9 in 2021:

117.96.6
×
\$100
=
\$1,786.36

\$100 in 1955 has the same "purchasing power" or "buying power" as \$1,786.36 in 2021.

To get the total inflation rate for the 66 years between 1955 and 2021, we use the following formula:

CPI in 2021 - CPI in 1955CPI in 1955
×
100
=
Cumulative inflation rate (66 years)

Plugging in the values to this equation, we get:

117.9 - 6.66.6
×
100
=
1,686%
