Refinancing Guide Australia

답부터 정리
Refinancing is worth considering when the total savings from a better rate or better features outweigh the switching costs and the time needed to break even. The decision should be based on net savings, fees, and how long you expect to keep the new loan.
Who this guide is for
Use this page if you are comparing refinance offers, wondering whether a cashback offer is really worth it, or trying to work out whether the break-even period justifies switching lenders.
Key Australian takeaways
- Refinancing should be judged on net savings after all switching costs, not on the headline rate alone.
- Owner-occupiers and investors may refinance for different reasons even when the monthly saving looks similar.
- If you are unlikely to stay beyond break-even, refinancing may not be worth the effort.
When refinancing usually makes sense
- Your current rate is materially above available alternatives and the saving survives all switching costs.
- Your current loan no longer fits your cashflow strategy because you need better features such as offset, flexibility, or a different repayment structure.
- Debt restructuring, cashflow management, or lender policy changes could improve your long-term position.
When refinancing may not be worth it
- The new rate is only slightly lower and the savings are largely absorbed by fees or break costs.
- You may sell, refinance again, or repay the loan before reaching break-even.
- The replacement loan strips away useful features or introduces terms that do not suit your future plans.
Break-even method
- Estimate the monthly saving after the new rate and fees are applied.
- Include discharge, application, valuation, legal, settlement, and any break cost if relevant.
- If the break-even period is longer than you expect to keep the loan, refinancing may not be worth the effort.
Owner-occupier vs investor refinance priorities
Owner-occupier
Owner-occupiers often care most about lower repayments, offset access, and household cashflow stability after the switch.
Investor
Investors may care more about flexibility, interest structure, cashflow management, and whether the refinance still suits the property strategy over time.
When not to refinance
If your savings are marginal, your loan may be repaid or sold soon, or the new product removes features you actively use, refinancing can look cheaper on paper without being better in practice.
Common refinance costs in Australia
- Existing lender discharge or settlement fees
- New lender application, valuation, or legal costs
- Possible break costs on a fixed-rate loan
- Government registration or transfer charges depending on structure
Australian examples
- Owner-occupier example: if switching saves about $250 per month after fees and the total switching cost is $2,500, the break-even point is around 10 months.
- Investor example: a refinance may still make sense even with moderate fees if it improves flexibility, loan structure, or long-run cashflow management.
FAQ
When is refinancing worth it? Usually when the net savings or feature improvements outweigh the switching costs and you expect to keep the new loan beyond the break-even point.
How do I calculate refinance break-even? Divide the total switching cost by the expected monthly saving after the new loan is in place. That gives you an approximate break-even month count.
Does refinancing reset my loan term? It can. Some borrowers reset to a longer term to reduce monthly repayments, but that may increase total interest if not managed carefully.
Can refinancing remove LMI? Sometimes. If your LVR has improved enough, refinancing may reduce or remove the need for LMI on the new loan, but lender policy still matters.
What fees should I expect when refinancing? Common costs include discharge fees, application fees, valuation, legal, settlement, and any break cost if the old loan is fixed.
