## Buying power of \$100 in 1931

This chart shows a calculation of buying power equivalence for \$100 in 1931 (price index tracking began in 1922).

For example, if you started with \$100, you would need to end with \$3,672 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$100 is equivalent to \$3,672 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 1931 dollars, the chart below shows how \$100 is worth less over 77 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, 1931 to 2008

Our calculations use the following inflation rate formula to calculate the change in value between 1931 and 2008:

CPI in 2008 CPI in 1931
×
1931 AUD value
=
2008 AUD value

Then plug in historical CPI values. The Australian CPI was 2.5 in the year 1931 and 91.8 in 2008:

91.82.5
×
\$100
=
\$3,672

\$100 in 1931 has the same "purchasing power" or "buying power" as \$3,672 in 2008.

To get the total inflation rate for the 77 years between 1931 and 2008, we use the following formula:

CPI in 2008 - CPI in 1931CPI in 1931
×
100
=
Cumulative inflation rate (77 years)

Plugging in the values to this equation, we get:

91.8 - 2.52.5
×
100
=
3,572%
