How to calculate inflation rate for $1, 1980 to 1981
Our calculations use the following inflation rate formula to calculate the change in value between 1980 and 1981:
CPI in 1981 CPI in 1980
×
1980 AUD value
=
1981 AUD value
Then plug in historical CPI values. The Australian CPI was 26.4 in the year 1980 and 28.9 in 1981:
28.926.4
×
