How much is it worth?
This is simple program for calculating historical money rates for Australia. It is intended to be a basic approach to calculating the relative value of money in Australia from 1850 to the present. It is based on the Retail Price Index developed by the Australian Bureau of Statistics.
Obviously using the Retail Price Index is but one means of calculating relative values. Comparisons of what something in worth in 1900 compared with 2025 could consider average weekly wage, the cost of a loaf of bread or a medium sized house.
The website Measuring worth provides more complicated comparisons using different criteria. This site has a specific page devoted to comparing values of Australian amounts - Measuring worth Australia.
