Refinancing FAQs

Savings depend on your loan balance and how much lower your new rate is. As a rule of thumb, each 0.25% rate reduction on a $600,000 loan saves approximately $1,500 per year ($125/month). On a $900,000 loan the same cut saves around $2,200 per year. Use this calculator with your exact figures to see your personalised savings — or use our Mortgage Repayment Calculator to compare repayments at different rates. Many Australian borrowers are paying 0.5–1.5% above the best available rate without realising it.
For a variable-rate loan, total refinance costs are typically $400–$2,000. The main costs are: discharge fee from your current lender ($150–$400), establishment fee at the new lender ($0–$700, often waived as an incentive), valuation fee ($0–$300, often waived), and legal/settlement fees ($150–$400). Fixed rate break costs are a different matter — they can range from $0 to $30,000+ depending on how far rates have moved since you fixed. Always ask your lender for an exact break cost estimate before deciding.
The break-even point is when cumulative savings exceed the total upfront costs. If refinancing costs $1,500 and saves you $300/month, you break even in 5 months. If it costs $3,000 and saves $200/month, break-even is 15 months. For most straightforward variable-rate refinances, borrowers break even within 6–18 months — after which every month is pure saving. This calculator shows your exact break-even date. Once you've refinanced, consider pairing your new loan with an offset account to save even more.
Yes, slightly. Each formal loan application results in a hard credit enquiry which can temporarily reduce your score by a small amount (typically 5–10 points). However, this effect is temporary and your score usually recovers within 6–12 months. Multiple applications within a short window can have a larger impact, so it's best to use a broker to identify the right lender before applying — rather than making multiple applications yourself.
Most experts recommend reviewing your home loan at least once every 1–2 years, or whenever the RBA moves the cash rate. Many borrowers drift onto a "revert rate" once an introductory period ends and end up paying 0.5–1.5% more than necessary. A mortgage broker review takes about 15 minutes of your time and is completely free. Learn more about your refinancing options or book a review with our team. Even if you decide not to switch, knowing your options puts you in a better position to negotiate with your existing lender.
