How to calculate inflation rate for $1, 1979 to 1980
Our calculations use the following inflation rate formula to calculate the change in value between 1979 and 1980:
CPI in 1980 CPI in 1979
×
1979 AUD value
=
1980 AUD value
Then plug in historical CPI values. The Australian CPI was 23.9 in the year 1979 and 26.4 in 1980:
26.423.9
×

=
Cumulative inflation rate (1 years)
Plugging in the values to this equation, we get:
26.4 - 23.923.9
