The consumer price index (CPI) in 1978 was 21.9. It was 20.3 in the previous year. This change in CPI is used by the Bureau of Statistics to calculate inflation.

According to the Bureau of Statistics consumer price index, the dollar experienced an average inflation rate of 4.16% per year. Prices in 2018 are 410.05% higher than prices in 1978.

In other words, AU$100 in 1978 is equivalent in purchasing power to AU$510.05 in 2018, a difference of AU$410.05 over 40 years.

The current inflation rate is now 0.45%^{1}. If this number holds, AU$100 today will be equivalent to AU$100.45 next year.

Cumulative price change | 410.05% |

Average inflation rate | 4.16% |

Converted amount (AU$100 base) | AU$510.05 |

Price difference (AU$100 base) | AU$410.05 |

CPI in 1978 | 21.9 |

CPI in 2018 | 111.7 |

This inflation calculator uses the following inflation rate formula:

CPI in 2018 / CPI in 1978 * 1978 AUD value = 2018 AUD value

Then plug in historical CPI values. The Australian CPI was 21.9 in the year 1978 and 111.7 in 2018:

111.7 / 21.9 * AU$100 = **AU$510.05**

AU$100 in 1978 has the same "purchasing power" or "buying power" as AU$510.05 in 2018.

This chart shows calculations of buying power equivalence over time for AU$100 in 1978 (price index tracking began in 1922).
