Terms of use

Last updated 19 August 2026.

OzCalc provides general-purpose calculators and explanatory notes. Results are estimates based on the inputs you enter and the published methods on each page.

Nothing on this site is tax advice, financial advice, legal advice, or a quote from a lender, employer or energy retailer. Rules change. Official sources listed on calculator pages take priority over this website.

You may use the calculators for personal, non-commercial research. You may not scrape the site to republish substantially identical calculator pages, or present the tools as an official government service.

The site is provided as is. We are not liable for decisions made using an estimate, including salary negotiations, loan applications or household budgets.
