How to calculate inflation rate for $1, 1972 to 1973

Our calculations use the following inflation rate formula to calculate the change in value between 1972 and 1973:

CPI in 1973 CPI in 1972
×
1972 AUD value
=
1973 AUD value

Then plug in historical CPI values. The Australian CPI was 11 in the year 1972 and 12 in 1973:

1211
×
$1
=
$1.09

$1 in 1972 has the same "purchasing power" or "buying power" as $1.09 in 1973.

To get the total inflation rate for the 1 years between 1972 and 1973, we use the following formula:

CPI in 1973 - CPI in 1972CPI in 1972
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:
