## How to Calculate Inflation Rate for \$1, 2009 to 2010

Our calculations use the following inflation rate formula to calculate the change in value between 2009 and 2010:

CPI in 2009 CPI in 2010
×
2010 AUD value
=
2009 AUD value

Then plug in historical CPI values. The Australian CPI was 96.1 in the year 2010 and 93.4 in 2009:

93.496.1
×
\$1
=
\$0.97

\$1 in 2010 has the same "purchasing power" or "buying power" as \$0.97 in 2009.

To get the total inflation rate for the 1 years between 2009 and 2010, we use the following formula:

CPI in 2009 - CPI in 2010CPI in 2010
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

93.4 - 96.196.1
×
100
=
-3%
