Are home loan refinance cashback offers worth it?

A cashback turns a refinance into something that looks like a windfall: move your home loan across, and a lump sum lands in your account a few weeks after settlement. The cash is real. Whether the loan underneath it is worth having is a separate question, and it is settled with arithmetic rather than with the size of the headline number.

Cashback campaigns come and go with the lending cycle. There have been stretches where most large lenders ran one and stretches where almost none did, so the only offer that matters is the one actually in front of you, on the day you are looking at it. What follows is how to judge it.

What is a home loan refinance cashback offer?

A refinance cashback is a one-off payment a lender makes to you for moving an existing home loan to it from somewhere else. It is paid after settlement, usually into an account held with that lender, and it is conditional. The loan has to settle. It almost always has to be a genuine refinance from another institution rather than an internal switch or a top-up. There is normally a minimum loan size and a maximum loan-to-value ratio, and the payment may be capped per property or per borrower no matter how many loans you move. Look at it as what it is: a customer-acquisition cost. The lender is buying a mortgage it expects to hold for years, and the cash is priced on the assumption that the interest earns it back. That is not a criticism of cashbacks — it is the frame you need to judge one.

Is a refinance cashback actually worth taking?

Sometimes, and the deciding factor is almost never the cashback itself. A cashback is a fixed, one-off amount. The interest rate is a recurring cost charged on your whole balance for as long as you hold the loan. On a large balance you expect to carry for many years, a small difference in rate outweighs a generous cashback; on a small balance you intend to clear quickly, the cashback can dominate. Work out which of those two situations you are in before you look at the number. The second half of the test is what the rate does after the first year or two. Where a cashback sits on a product that is sharp at the start and drifts afterwards, the loan can cost you more by year three than staying put would have. Compare the ongoing rate first, and let the cashback break a tie between two loans you would have been content with either way.

A cashback is a one-off payment set against a recurring cost. If the rate behind it is not competitive on its own, the cash is buying you a worse loan.

How do you work out whether the cashback covers the switching costs?

Switching is not costless, so start by listing what leaving and arriving actually cost. Leaving can involve a discharge fee from your current lender and, if you are inside a fixed term, break costs — which only your current lender can quote, and which can be large enough on their own to end the conversation. Arriving can involve an application or settlement fee, a valuation, a lender's annual or package fee, and the state government fees for discharging one mortgage and registering another. Subtract that total from the cashback to see what is genuinely left over. Then do the part most people skip: work out the difference in monthly repayment between the two loans, and how many months of that difference the leftover cash represents. That number is your break-even point, and it tells you how long the new loan has to behave before the switch was worth making. Our loan comparison calculator will run both loans side by side including fees.

What conditions usually sit in the fine print?

Read the offer terms before the marketing page, because the conditions are where cashbacks are won and lost. The ones that recur are a minimum loan amount, a maximum loan-to-value ratio, a requirement that the loan comes from another institution, an application window and a settlement deadline, and a limit of one payment per property or per borrower. Some offers exclude particular products, such as lines of credit or certain investment structures. Many attach a clawback: refinance away, or pay the loan out, inside a defined period and the lender can reclaim the payment. Timing matters too — the money often arrives weeks after settlement, and sometimes only once the first repayment has been made, so it is not there for your settlement costs. Offers can also be varied or withdrawn without notice, which is why an offer you read about last month is not the offer you will be applying under.

Does a refinance cashback have tax consequences?

It can, and it is a question for your accountant or for the Australian Taxation Office rather than for a broker. The treatment is not automatically the same for every borrower, and an investment loan — where borrowing costs are deductible — is not in the same position as a loan on the home you live in. A loan split between the two adds another layer. We arrange finance; we do not give tax advice, and a cashback counted as spendable in the year it arrives is the kind of thing that resurfaces at the wrong moment. Keep the lender's written offer terms and the settlement statement with your records, because your accountant will want to see what the payment was for and when it landed. If the refinance is also releasing equity for an investment purpose, raise that with them at the same time, since how the new borrowing is structured affects far more than the cashback does.

What should you compare instead of the cashback?

Four things, in this order. The ongoing interest rate, because that is the recurring cost. The Comparison Rate, because it folds the standard fees into a single figure and is the only like-for-like number on an advertised loan — our guide on how to read a Comparison Rate explains what it does and does not capture. The features you will genuinely use, such as an offset account, redraw, a split, or unlimited extra repayments, since paying a package fee for features you never touch is a cost with no return. And the loan term you are resetting to. Refinancing back to a fresh thirty-year term lowers the monthly repayment and raises the total interest paid, which is the quietest way a switch that looked good turns expensive. Ask the new lender to match your remaining term if the repayment still works for you.

Next step

Pull out your current loan statement and write down five things: the balance, the interest rate, the remaining term, whether any part is fixed and when that ends, and the annual fee. Add a realistic value for the property. With that on one page, a broker can tell you whether your current rate is out of step with what is being written today, what a switch would cost to arrange, and whether any cashback on the table survives the arithmetic once the costs come out. Our refinance broker page sets out how the review runs, and if the aim is to clear other debts at the same time, our guide to using a mortgage for debt consolidation covers that structure. Send the page through on WhatsApp and we will work through it with you.
