How this calculator decides between repricing and refinancing
It prices both paths on the same loan and picks a lane. Your rate is compared against an indicative market range for your loan — set by purpose, repayment type and LVR band, dated on screen, and reviewed monthly. The gap between the two is your loyalty gap: what staying loyal is costing you each year.
From there it costs the two ways to close that gap. Repricing — asking your current bank’s retention team for a rate review — costs nothing and lands in days, but banks rarely cut more than about a percentage point in one move, so a big gap can’t be fully closed by asking. Refinancing reaches the sharper rate but has to earn back the discharge, government and establishment costs first, which is why the tool shows a break-even month rather than a headline saving. The verdict tells you which move to make first — and when the honest answer is to do both in sequence, or nothing at all.
Every result shows its working. Open “How we calculated this” under your result to see the exact figures, assumptions and formulas behind your verdict.
Why ask your own bank before refinancing?
Because lenders price on risk bands, not loyalty – and your band has probably moved since your loan settled. Your rate was set on the day you borrowed. Since then the market has moved, your balance has fallen, and your property value has likely changed, which means your loan-to-value ratio may have dropped into a band your bank prices more sharply. That pricing exists right now; nobody has asked for it on your behalf.
A rate review request costs nothing, takes days, and – when it arrives with evidence rather than a vague complaint – captures most of the available saving for the majority of borrowers. Refinancing only wins clearly when the gap is larger than a retention team will close in one move. That’s not a reason to avoid switching; it’s a reason to sequence it. Ask first, hold the refinance analysis in reserve, and move only if the bank won’t. Either way, you negotiate from a position of knowing your numbers – which is the entire point of this page. The full picture on when switching genuinely wins, what it costs and how we run it is on our refinancing your home loan page.
What the result can’t see
The calculator prices your scenario against an indicative market range for a clean, full doc loan. It doesn’t test serviceability – a gap worth chasing means nothing if a new lender won’t approve the switch, and that’s assessed on income, expenses, existing limits and policy, not on the rate. It doesn’t model fixed-rate break costs, lenders mortgage insurance on a higher-LVR move, annual package fees, cash-out or debt consolidation, or the valuation a new lender would actually order. Alt doc, self-employed and credit-impaired scenarios price differently again – that’s a conversation, not a calculator. Treat your verdict as the reason to have the conversation, not the outcome of it.
Frequently asked questions
Should I refinance or just ask my bank for a lower rate?
Ask your bank first in most cases. A rate review costs nothing, takes days, and typically recovers most of the gap between your rate and the market – banks respond to customers who ask with evidence. Refinance when the gap is too large for one retention decision to close, or when your bank refuses. This calculator tells you which situation you’re in before you spend anything.
Will my bank actually lower my rate if I ask?
Often, yes – retention teams exist precisely because replacing a customer costs a bank more than repricing one. What changes the odds is specificity: quoting your rate, your balance, your LVR band, the market range for that band, and a response deadline. The Game Plan this tool produces includes that request as a ready-to-send letter merged with your own figures.
How much does it cost to refinance a home loan in NSW?
Typically a discharge fee from your current lender, NSW government discharge and mortgage registration fees, and a new lender’s establishment cost – commonly somewhere around a thousand to fifteen hundred dollars all up, with some lenders waiving parts of it and occasional cashback offers offsetting the rest. The calculator itemises current estimates, dates them, and divides them by your monthly saving to give you a break-even month.
What is a loyalty gap on a home loan?
It’s the difference between the rate you’re paying and the indicative market range for a borrower in your LVR band with your loan purpose and repayment type. It exists because rates are set on the day you borrow while the market and your equity keep moving. Multiplied by your balance, it’s what loyalty costs you per year – and it’s the number this calculator puts in front of you first.
Does this calculator check my credit or send my details anywhere?
No. The verdict, both scenario cards, the break-even month and the five-year comparison are calculated in your browser, with no contact details required and no credit check performed. Details are only asked for if you want your Game Plan emailed to you, or want us to run the repricing for you – and nothing goes to any lender without your say-so.
Can Evolve handle the repricing for me?
Yes. Once your Game Plan is unlocked, you can hand us the request three ways: upload a screenshot of your loan account, type in the BSB, account number, balance and rate, or use a secure encrypted bank data transfer that never records your login details. We confirm everything with you within one business day before anything goes to your lender.
Does it work for investment loans and interest only?
Yes. Investment and interest only loans are compared against their own indicative market ranges, not the owner-occupied ones – the pricing difference between those categories is exactly why the tool asks. Both the reprice letter and the refinance numbers adjust to match.
What if I’m on a fixed rate?
Run it anyway, but don’t act on the result until you have your break cost. Break fees are calculated by your lender using their own formula and can be substantial or near zero depending on where rates have moved since you fixed. If the gap is large, the right time to act may be at your fixed expiry – which is also when revert rates quietly create the biggest loyalty gaps.
