Understanding Refinance Cashback Offers and Costs

A cashback offer is a one-off payment, so the loan behind it matters far more than the payment itself.

If you live in Hampton East and have seen a lender advertising cash to switch, it is worth slowing down before you apply. A cashback can be a welcome bonus. It can also distract from a higher interest rate that you pay every month for years.

What Is a Refinance Cashback Offer?

A refinance cashback offer is a payment a lender makes to you when you move your loan to them and meet their conditions. It is a marketing incentive, not a discount on your loan.

The conditions are set by each lender and can change. Before you apply, check the minimum loan size, how long the offer is open, and whether you need to keep the loan for a set period. Also check what happens to the cash if you leave early. These details sit in the offer terms, so read them closely.

When you refinance your home loan, the cashback is only one part of the picture. The rate, fees, features and repayments all shape what the loan costs you.

Cashback or Lower Rate: A Worked Comparison

A lower rate usually wins over a cashback if you plan to keep the loan for many years, while a cashback can win over a shorter stretch. The break-even point depends on the size of the rate gap.

As an example, consider a Hampton East homeowner with $600,000 left to pay over 25 years. Two lenders make offers. Lender A offers $3,000 cashback at 6.85% p.a. Lender B offers no cashback at 6.75% p.a. Both rates are illustrative only.

At 6.75% p.a., the monthly repayment is about $4,145. At 6.85% p.a., it is about $4,183. That is roughly $38 more each month, or around $456 a year, for Lender A.

The $3,000 cashback covers that extra repayment for about six and a half years. If the homeowner expects to stay with the loan for around four years before selling or refinancing again, Lender A comes out ahead. If they plan to hold it for 15 or 20 years, Lender B costs less overall, because the extra repayments keep adding up long after the cash is spent.

This comparison leaves out fees and assumes the rates stay as shown. Variable rates can move, so the real gap may change. You can test your own numbers with our mortgage repayment calculator.

Costs That Can Eat Into Your Cashback

Switching can involve several costs, and they can shrink or cancel out a cashback. Moneysmart lists a break fee on a fixed rate loan, a discharge or termination fee on your current loan, and an application fee on the new loan.

There is also a switching fee if you refinance with your current lender. If you have less than 20 per cent equity, you might have to pay lenders mortgage insurance, which adds to the cost of switching. Fees are set by each lender, so ask for the exact amounts in writing.

Some costs do not apply in Victoria. Mortgage duty was abolished in Victoria from 1 July 2004, so you should not face stamp duty on the new mortgage here. Federal rules also ban most exit fees on residential loans entered into on or after 1 July 2011. That ban does not cover break fees or discharge fees, so those can still apply.

If the loan is for an investment property, ask your accountant how borrowing expenses and any cashback are treated for tax. Tax outcomes depend on your circumstances.

Coming Off a Fixed Rate? Check the Timing

If your fixed rate is ending soon, the end of the term is usually the cheapest moment to switch, because a break fee is charged only when you leave a fixed loan early. Variable loans do not carry a break fee.

A Hampton East homeowner who leaves a fixed loan early may face a break fee larger than any cashback on offer. Ask your lender for a break cost estimate before you commit. If your term is close to ending, you can line up a new loan so the switch happens once the fixed period finishes. Our page on fixed rate expiry explains what to expect as the date approaches.

Will You Qualify to Switch Lenders?

You might not qualify, even if you already repay a loan on time. A new lender must assess your finances under its own rules and cannot assume your current loan was suitable.

Banks must test whether you could meet repayments at a rate at least 3 percentage points above the loan rate. APRA confirmed in May 2026 that this buffer stays at 3 percentage points. Changes in your income, your debts or the value of your home can affect the result.

If you borrow more than your current balance, for example to renovate, the switch is no longer a like-for-like move. The lender will look closer at the extra debt. Repayment history also matters. ASIC guidance says a lender can reasonably focus on your payment record when you refinance to a lower rate without borrowing more.

Should You Stay, Switch or Ask Your Lender to Match?

You should switch only when the total savings outweigh the costs and any benefits you would lose. ASIC's guidance for lenders and brokers points to the same test: overall cost savings, including any broker fees, must outweigh what you give up.

Features count too. If you rely on an offset account or redraw, check the new loan offers them and what they cost. A lower rate with fewer features is not always a win for your cashflow.

A loan health check is a practical first step. We review your current rate, fees and features, then tell you plainly whether switching makes sense or whether staying put is the sensible call. Sometimes a call to your current lender to ask for a lower rate is all that is needed.
