Buying power of \$100 in 1955

This chart shows a calculation of buying power equivalence for \$100 in 1955 (price index tracking began in 1922).

For example, if you started with \$100, you would need to end with \$1,771.51 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$100 is equivalent to \$1,771.51 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.
