## How to Calculate Inflation Rate for \$100, 2015 to 2021

Our calculations use the following inflation rate formula to calculate the change in value between 2015 and 2021:

CPI in 2021 CPI in 2015
×
2015 AUD value
=
2021 AUD value

Then plug in historical CPI values. The Australian CPI was 107.7 in the year 2015 and 118.8 in 2021:

118.8107.7
×
\$100
=
\$110.31

\$100 in 2015 has the same "purchasing power" or "buying power" as \$110.31 in 2021.

To get the total inflation rate for the 6 years between 2015 and 2021, we use the following formula:

CPI in 2021 - CPI in 2015CPI in 2015
×
100
=
Cumulative inflation rate (6 years)

Plugging in the values to this equation, we get:

118.8 - 107.7107.7
