How to calculate inflation rate for $1, 1974 to 1975

Our calculations use the following inflation rate formula to calculate the change in value between 1974 and 1975:

×
1974 AUD value
=
1975 AUD value

Then plug in historical CPI values. The Australian CPI was 13.9 in the year 1974 and 16 in 1975:

1613.9
×
$1
=
$1.15

$1 in 1974 has the same "purchasing power" or "buying power" as $1.15 in 1975.

To get the total inflation rate for the 1 years between 1974 and 1975, we use the following formula:

CPI in 1975 - CPI in 1974CPI in 1974
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

16 - 13.913.9
