The consumer price index (CPI) in 1951 was 5.2. It was 4.4 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 4.68% per year. Prices in 2018 are 2,048.08% higher than prices in 1951.

In other words, AU$100 in 1951 is equivalent in purchasing power to AU$2,148.08 in 2018, a difference of AU$2,048.08 over 67 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 | 2048.08% |

Average inflation rate | 4.68% |

Converted amount (AU$100 base) | AU$2,148.08 |

Price difference (AU$100 base) | AU$2,048.08 |

CPI in 1951 | 5.2 |

CPI in 2018 | 111.7 |

This inflation calculator uses the following inflation rate formula:

CPI in 2018 / CPI in 1951 * 1951 AUD value = 2018 AUD value

Then plug in historical CPI values. The Australian CPI was 5.2 in the year 1951 and 111.7 in 2018:

111.7 / 5.2 * AU$100 = **AU$2,148.08**

AU$100 in 1951 has the same "purchasing power" or "buying power" as AU$2,148.08 in 2018.

This chart shows calculations of buying power equivalence over time for AU$100 in 1951 (price index tracking began in 1922).

Politics and news often influence economic performance. Here's what was happening at the time:

- Stalin's announces that the USSR has developed an atomic bomb.
- Luis Miramontes, a Mexican chemist, successfully synthesises the first oral contraceptive.
- The first underground atomic explosion happens at Frenchman Flat, Nevada.

Raw data for these calculations comes from the government of Australia's annual (CPI) as provided by the Reserve Bank of Australia. The consumer price index was established in 1922 and is tracked by Australian Bureau of Statistics (ABS).
