About Refinance Home Loan Calculator (Australia)
Australia named the phenomenon: the LOYALTY TAX — back-book borrowers pay 0.3–1% more than new customers at the same bank, worth ~$2,800/year at the defaults ($520,000 at 6.7% versus a 5.9% new-customer rate). Refinancing here is unusually cheap and fast (discharge ~$350, state registration, often no application fee, all-digital lenders settling in days), so the verdict above breaks even within months for most spreads worth typing in. Cashbacks ($2,000–4,000 in promo seasons) changed the game and bred a sport: serial refinancing — moving every 12–24 months, harvesting cashbacks while resetting to new-customer pricing. It's legitimate and lucrative for clean-credit borrowers with stable income and LVR under 80%, but mind the frictions: each application is a credit inquiry, lenders increasingly claw back cashbacks for sub-12-month exits, and a string of refinances right before a major loan application muddies the file. Cheaper first move: the retention call. Tell your bank you have a competitor rate (have a real one); retention teams routinely match or near-match within 48 hours — capturing most of the saving for none of the paperwork. Escalate to actual refinancing when they stiff you, when your LVR has improved into a better band, or when offset/feature needs changed. Compare on rate AND package fee ($300–400/year) AND offset functionality — the trio decides the true cost, and this calculator's fee field absorbs whatever combination you're weighing.

Frequently asked questions
What does refinancing actually cost in Australia?+
Modest: discharge fee ~$275–400, state mortgage-registration transfer ~$120–220, sometimes a new-loan application/valuation fee (often waived in promos) — typically $700–1,500 all-in, frequently more than covered by a cashback. Fixed-rate loans add break costs (ask for a payout quote); variable loans have had no exit fees since 2011.
Are refinance cashbacks taxable income?+
For owner-occupiers, the ATO treats personal cashbacks as non-assessable — not income. INVESTORS should get advice: cashbacks on investment loans can affect cost-base/deduction calculations. Either way, factor the clawback clause (typically repayable if you leave within 12 months) before counting it as free money.
How often is too often to refinance?+
Mathematically: whenever savings + cashback exceed costs — even annually. Practically: keep 6+ clean months before any major credit application, watch cumulative inquiries (5+ in two years starts to drag scores), and confirm each new lender's clawback window has lapsed. Many Australians settle into an 18–24 month rhythm; the spreadsheet stays happy.
Retention offer le loon ya phir bhi switch karoon?+
Retention match 0.1% ke andar aa jaye to ruk jaana theek hai — paperwork zero, saving lagbhag poori. Par yaad rakhein: jis bank ne loyalty tax lagaya tha, woh 18 mahine me phir lagayega. Calendar me yearly 'rate audit' reminder rakhein; yeh 15-minute ki call Australia ki sabse achhi hourly-rate wali kamai hai.
