Buying power of $1 in 1970

This chart shows a calculation of buying power equivalence for $1 in 1970 (price index tracking began in 1922).

For example, if you started with $1, you would need to end with $1.22 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $1.22 over time, that means that the "real value" of a single Australian dollar decreases over time. In other words, a dollar will pay for fewer items at the store.

This effect explains how inflation erodes the value of a dollar over time. By calculating the value in 1970 dollars, the chart below shows how $1 is worth less over 3 years.

How to Calculate Inflation Rate for $1, 1970 to 1973

Our calculations use the following inflation rate formula to calculate the change in value between 1970 and 1973:

CPI in 1973 CPI in 1970
×
1970 AUD value
=
1973 AUD value

Then plug in historical CPI values. The Australian CPI was 9.8 in the year 1970 and 12 in 1973:

129.8
×
$1
=
$1.22

$1 in 1970 has the same "purchasing power" or "buying power" as $1.22 in 1973.

To get the total inflation rate for the 3 years between 1970 and 1973, we use the following formula:

CPI in 1973 - CPI in 1970CPI in 1970
×
100
=
Cumulative inflation rate (3 years)

Plugging in the values to this equation, we get:

12 - 9.89.8
×
100
=
22%
