About ozfinancecalc.com.au
ozfinancecalc.com.au is a free hub of Australian finance calculators built to answer the money questions that actually cost people money — how much you can borrow, what a loan really costs, what stamp duty you'll pay, and what you keep after tax.
What we offer
Nine free, no-sign-up calculators covering home loans (borrowing power, repayments, stamp duty), personal lending (car, personal and credit-card repayments) and tax & super (income tax, capital gains tax and superannuation) — each built for Australian rates and rules.
How we keep it accurate
Our calculators use current Australian figures — RBA cash rate and lender rates, APRA serviceability rules, ATO 2025–26 tax scales, state stamp-duty schedules and the 12% Super Guarantee — and we date our figures so you know how current they are. Sources include the RBA, ASIC MoneySmart and the ATO.
Important
We provide general information and estimates only — not financial, credit, tax or legal advice. The tools don't consider your personal circumstances. For advice specific to you, speak to a licensed professional. See our disclaimer.
