Estimates only — not a loan offer, credit quote or financial advice. These calculators use current-year resident tax rates including LITO and the Medicare low-income phase-in; choosing a family household applies the simplified $47,238 family threshold plus $4,338 per dependent child. They also use the configured rental-income haircut and assessment buffer, a 30-year P&I term, and standard investor stamp duty (no concessions or surcharges). Real lender assessments use their own expense benchmarks (HEM), buffers, LVR caps and policies, and vary between lenders. Confirm your actual capacity with a licensed mortgage broker before making offers.
