According to the Bureau of Statistics consumer price index, today's prices in 2020 are 3,931.71% higher than average prices since 1929. This means that a dollar today only buys 2.48% of what it could buy in 1929. The Australian dollar experienced an average inflation rate of 4.15% per year during this period, causing the real value of a dollar to decrease.

In other words, \$100 in 1929 is equivalent in purchasing power to about \$4,031.71 in 2020, a difference of \$3,931.71 over 91 years.

The 1929 inflation rate was 0.00%. The current year-over-year inflation rate (2019 to 2020) is now 1.90%1. If this number holds, \$100 today will be equivalent in buying power to \$101.90 next year.

## Buying power of \$100 in 1929

This chart shows a calculation of buying power equivalence for \$100 in 1929 (price index tracking began in 1922).

For example, if you started with \$100, you would need to end with \$4,031.71 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$100 is equivalent to \$4,031.71 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.

=
\$4,031.71

\$100 in 1929 has the same "purchasing power" or "buying power" as \$4,031.71 in 2020.

To get the total inflation rate for the 91 years between 1929 and 2020, we use the following formula:

CPI in 2020 - CPI in 1929CPI in 1929
×
100
=
Cumulative inflation rate (91 years)

Plugging in the values to this equation, we get:

116.91944859999998 - 2.92.9
×
100
=
3,932%
