Calculator Prices


This page shows a few references to the original prices of mechanical and early electronic calculators in Australia.

One pound (£1-0-0) became two dollars ($2.00) when Australia changed to decimal currency in February 1966.

One Australian dollar was equivalent to about US$1.10 from the 1950s until the 1980s. In recent years it has ranged from US$0.45 to US$1.08.
