Refinance Calculator NSW: How to Work Out If You'll Save
The five inputs that actually decide whether refinancing your NSW home loan is likely to save money — and how to sanity-check any online calculator result.

A $3,000 cheque for signing a new home loan sounds like free money. In July 2026, more than a dozen Australian lenders are dangling cashback offers between $2,000 and $4,000 to lure Sydney refinancers across, and the deals are back to levels we haven't seen since 2023. The problem is that the sharpest cashback is rarely on the sharpest-rate loan — and a $3,000 cheque today can quietly cost you $6,000 in extra interest over three years if the maths goes the wrong way.
This is the honest guide to how cashback refinance offers actually work in 2026, which lenders are paying what right now, and the three-number test we run for every Sydney client before recommending a switch.
If you'd rather skip the reading and have us run the numbers on your file directly, a free 15-minute rate review with Kevin gets you a clear answer. We'll compare the current cashback offers against straight-rate deals on the OLEND lender panel.
A refinance cashback is a lump-sum payment — usually between $2,000 and $4,000 — that a new lender pays into your nominated account after your refinance settles. It's designed to offset the switching costs of moving your home loan and to give you an obvious short-term reason to change banks.
According to Mozo's 2026 tracker, there are roughly 13 cashback home loan offers available in Australia as of mid-2026, with amounts tiered by loan size and most requiring a minimum $250,000 balance and a maximum 80% loan-to-value ratio.
The cashback is real. The trap is that the interest rate attached to the cashback loan is usually 0.15% to 0.20% higher than the sharpest non-cashback rate on the market (HomeLoanAI, July 2026). On a Sydney-sized loan, that premium compounds fast.
Here are the current offers on the market, drawn from public lender promotions and third-party comparison databases. Amounts and eligibility change without notice — check directly with the lender before applying.

Missing from the list are Westpac, NAB, and CommBank's mainstream cashbacks — the big banks pulled out of the general cashback race in 2023 and haven't returned. ANZ is the only major still running a cashback, and it's now first-home-buyers only.
Before I tell any client to chase a cashback, I run three numbers against their file. If the cashback still wins after all three, it's a real deal.
Find the sharpest non-cashback rate you'd qualify for. In July 2026, that's roughly 5.69% p.a. variable for owner-occupier P&I on strong files, per Mozo's June 2026 rate data. Then find the rate attached to the cashback loan you're being offered. The gap between them is the rate premium.
If the cashback loan is 5.89% and the sharpest non-cashback loan is 5.69%, the premium is 0.20% — and that premium is how the lender funds the cashback.
Divide the cashback by the extra monthly interest you'd pay on the cashback loan versus the sharpest alternative.
For a $650,000 loan on a 27-year P&I term:
If you plan to hold the loan longer than 37 months without refinancing again, the cashback loses. If you plan to refinance again within 24–36 months, it wins.
Every cashback comes with a clawback clause. Most lenders require you to keep the loan for at least 12 months, and some extend that to 24 months (HomeLoanAI). If you refinance or sell within that window, you must repay the cashback in full.
That effectively locks you into the higher-rate loan for the clawback period. If a genuinely better deal comes onto the market three months later — and in 2026's shifting rate environment, that happens — you're stuck.
Say you have a $650,000 owner-occupier variable loan with 27 years left, currently on 6.55% (a common Sydney refinance profile in mid-2026). You're offered two options:
Option A looks better in year 1. But look what happens over five years, assuming rates stay flat:
Option B pulls ahead in year 3. Over 10 years the gap grows to roughly $4,000 in Option B's favour, and that's before compound effects on offset balances or extra repayments.
Numbers are indicative only. Actual rate, fees, and approval depend on lender policy and your circumstances at the time of application.
Cashback offers aren't always a trap. They stack up when:
Cashback offers usually don't stack up when:
Under APRA's serviceability buffer rules, lenders must test your ability to repay a new loan at the actual rate plus a 3% buffer. A cashback loan at 5.89% is assessed at ~8.89%; a non-cashback loan at 5.69% is assessed at ~8.69%. That 0.20% difference in the assessment rate can push borrowers on tight files below the approval line at the cashback lender while they'd still qualify at the sharper-rate lender.
APRA also enforces a debt-to-income cap of around 6× gross income for most new lending, which further tightens who can chase a cashback (HomeLoanAI). If your file is anywhere near the DTI ceiling, the rate matters more than the cheque.
Yes. Around 13 lenders are running cashback offers as of July 2026, with amounts between $2,000 and $4,000, per Mozo's tracker. Westpac, NAB, and CommBank withdrew their mainstream cashbacks in 2023; ANZ still runs a first-home-buyer offer.
Cashback offers are usually funded by a modest rate premium on the underlying loan — typically 0.15% to 0.20% higher than the sharpest non-cashback rate on the market (HomeLoanAI). Over a large loan held for several years, that premium can outweigh the upfront cheque.
A clawback clause requires you to repay the cashback in full if you refinance or sell within a set period — usually 12 months, sometimes 24. This effectively locks you into the loan for the clawback period.
Most lenders require a minimum loan balance of around $250,000 to $350,000 to qualify for cashback. A few lenders use different thresholds (AMP Bank at $100,000; Bank of China at $400,000). The largest cashback amounts ($4,000) generally require a loan of $750,000 or more.
Cashback is generally not treated as assessable income for owner-occupied home loans — the ATO typically views it as a rebate reducing the cost of the loan. For investment loans, treatment can differ and the cashback may reduce your deductible interest. This isn't tax advice — talk to your accountant before relying on the tax outcome.
OLEND has access to 40+ lenders and 300+ products, and we hold a 5.0 rating from 21 Google reviews. When a client asks about a cashback, we run the three-number test against their actual file — current rate, remaining term, offset balance, serviceability, hold horizon — and compare the cashback loan side-by-side against the sharpest non-cashback options on the same panel. You can see the full picture on our dedicated refinancing page.
If the sharpest non-cashback loan beats the cheque on your file, we'll tell you. If the cashback genuinely wins, we'll tell you that too.
If you're weighing up a cashback offer, here's the honest process:
