### Buying power of \$100 in 1945

This chart shows a calculation of buying power equivalence for \$100 in 1945 (price index tracking began in 1922).

For example, if you started with \$100, you would need to end with \$825.00 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$100 is equivalent to \$825.00 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 1945 dollars, the chart below shows how \$100 buys less over the past 35 years.

According to the Bureau of Statistics, each of these AUD amounts below is equal in terms of what it could buy at the time:

### How to Calculate Inflation Rate for \$100, 1945 to 1980

This inflation calculator uses the following inflation rate formula:

CPI in 1980CPI in 1945
×
1945 AUD value
=
1980 AUD value

Then plug in historical CPI values. The Australian CPI was 3.2 in the year 1945 and 26.4 in 1980:

26.43.2
×
\$100
=
\$825.00

\$100 in 1945 has the same "purchasing power" or "buying power" as \$825.00 in 1980.

To get the total inflation rate for the 35 years between 1945 and 1980, we use the following formula:

CPI in 1980 - CPI in 1945CPI in 1945
×
100
=
Cumulative inflation rate (35 years)

Plugging in the values to this equation, we get:

26.4 - 3.23.2
×
100
=
725%
