Cashback offers come and go with the market. When lenders want to win refinancing volume, the cashbacks appear: $2,000, $3,000, sometimes $4,000 just for switching. They’re genuinely tempting, and sometimes genuinely good. But they’re also one of the easiest ways to be steered toward a loan that costs you more over time. Here’s how to tell the difference.
How refinance cashbacks work
A cashback is a one-off payment, paid by the lender after your refinance settles, as an incentive to switch to them. It usually lands in your account a few weeks after settlement. The amount and availability change constantly, depending on which lenders are chasing market share at the time.
There’s nothing inherently wrong with them. The catch is that the cashback is the visible number, while the rate, the number that actually determines your long-term cost, is easy to overlook.
The trap: a cashback on a worse rate
Here’s the maths that catches people. Imagine two refinance options on a $600,000 loan:
- Option A: 6.10% rate, no cashback
- Option B: 6.40% rate, $3,000 cashback
Option B looks better, $3,000 in your pocket. But the 0.30% higher rate on $600,000 costs you roughly $1,800 a year in extra interest. The $3,000 cashback is wiped out in under two years, and after that, Option B keeps costing you $1,800 every year for the life of the loan.
Over five years, Option A saves you far more than the cashback ever delivered. The cashback was the bait, the rate was where the real money moved.
When a cashback is genuinely worth it
Cashbacks aren’t a trick, they’re only a trap when they distract from the rate. A cashback is genuinely good when:
- The rate is competitive on its own merits, and there’s a cashback on top
- The cashback covers your switching costs (discharge, registration, application fees), making the refinance effectively free to execute
- You’re refinancing anyway for sound reasons, and the cashback is a bonus rather than the reason
In other words: choose the loan on the rate and the fit first. If a strong option also happens to carry a cashback, that’s a genuine win.
How to evaluate any cashback offer
Run this quick check:
- What’s the rate, and how does it compare to the best available rate you’d qualify for without a cashback?
- What’s the annual cost of any rate gap versus the no-cashback option? (Rate difference × loan balance.)
- How long until the rate gap eats the cashback? If it’s under two years, be cautious.
- What are the ongoing fees? A cashback loan with higher annual fees compounds the problem.

What a broker checks that you might miss
When weighing a cashback offer, a broker looks past the headline at:
- The comparison rate (which factors in fees), not just the advertised rate
- Whether the cashback has clawback conditions (some require you to stay for a minimum period)
- Whether the loan has the features you need, an offset, redraw, splits, see how loan features affect the real cost
- Whether a non-cashback lender quietly offers a better total deal
Why cashbacks work on people (and how to resist)
Cashbacks are effective marketing because they exploit a quirk in how we weigh money: a $3,000 cash payment landing in a few weeks feels far more real and immediate than $1,800 a year of extra interest spread invisibly across a 30-year loan. The cash is concrete and soon; the rate cost is abstract and distant. That’s precisely why lenders use them, the cashback grabs attention while the rate does the quiet work. The way to resist is simple: always convert both numbers to the same basis. Ask “what does this cost me per year, every year, versus the cashback I get once?” Once the rate gap is expressed as an annual figure and compared against the one-off cash, the better deal usually becomes obvious, and it’s often not the one with the cashback.
The Bottom Line
Refinance cashbacks are real money, and sometimes a genuinely good sweetener. But they’re a sweetener, not a reason. Choose your refinance on the rate, the fees, and the fit. If a strong option also carries a cashback, take it gladly, just never let the cashback choose the loan.

Frequently Asked Questions
Q1. Are refinance cashback offers worth it?
Ans. Only if the loan’s interest rate is also competitive. A cashback on a higher rate is often a net loss within a year or two, because the rate gap outweighs the one-off cash.
Q2. How much are refinance cashbacks in Australia?
Ans. Typically $2,000–$4,000, though the amount and availability change constantly depending on which lenders are chasing market share at the time.
Q3. What’s the catch with cashback home loans?
Ans. The cashback is the visible number, but the rate determines your long-term cost. A higher rate paired with a cashback can cost more overall than a lower rate with no cashback.
Q4. How do I know if a cashback deal is genuinely good?
Ans. Compare the total cost over time. If the rate is competitive on its own merits and there’s a cashback on top, it’s a genuine win. If the cashback comes with a higher rate, do the maths first.
Q5. Do I have to pay tax on a refinance cashback?
Ans. The tax treatment of cashbacks isn’t always straightforward and can depend on whether the loan is for an owner-occupied home or an investment property. Rather than rely on a general rule, confirm your situation with your accountant or the ATO before assuming.
Q6. Can a cashback cover my switching costs?
Ans. Often yes. A $2,000–$3,000 cashback can offset discharge, registration, and application fees, making the refinance effectively free to execute, provided the rate stacks up.
Q7. Are there conditions on refinance cashbacks?
Ans. Sometimes. Some have clawback clauses requiring you to stay with the lender for a minimum period, or minimum loan amounts and LVR requirements. Always read the conditions.
Q8. Should I choose a loan based on the cashback?
Ans. No. Choose based on rate, fees, and features first. Treat the cashback as a bonus on an already-good option, never as the deciding factor.
Q9. Why do lenders offer cashbacks?
Ans. To win refinancing volume. Acquiring a new mortgage customer is valuable to a lender, so a one-off cashback can be worth it to them, even if the rate isn’t market-leading.
Q10. How long until a higher rate cancels out the cashback?
Ans. Divide the cashback by the annual cost of the rate gap. On a $600,000 loan, a 0.30% gap costs ~$1,800/year, so a $3,000 cashback is gone in under two years.
