Cashback offers can range from a few hundred dollars to several thousand, but they almost always come attached to conditions that affect what you actually keep.
Lenders use cashback to attract borrowers who might otherwise refinance to a competitor. The payment usually lands in your account within weeks of settlement, but the value depends entirely on whether the loan itself suits your circumstances. A $3,000 cashback on a loan that costs you an extra $80 per month in interest leaves you worse off after three years.
1. Know What Cashback Actually Covers
Cashback is meant to offset some of the upfront costs of refinancing, such as application fees, valuation fees, or discharge fees from your current lender. Some lenders pay the cashback directly into your new loan account, while others transfer it to your nominated bank account. The payment method matters because if it goes straight into the loan, it reduces your balance immediately rather than giving you cash to spend.
Consider a teacher refinancing a $450,000 mortgage who receives $2,000 cashback. If the cashback covers the $600 discharge fee, $200 application fee, and $400 valuation fee, you're left with $800 in genuine benefit. If the new loan has a rate 0.15% higher than a comparable product without cashback, you'll pay an extra $675 per year in interest, which wipes out the benefit in just over a year.
2. Compare the Interest Rate With and Without Cashback
Cashback loans often carry slightly higher interest rates than equivalent products without the incentive. The difference might only be 0.05% to 0.20%, but over the life of a loan, that compounds. A $400,000 loan with a rate 0.10% higher costs roughly $400 more per year, which adds up to $12,000 over a typical 30-year term.
When assessing a cashback offer, calculate how long it takes for the higher interest cost to exceed the cashback amount. If you receive $2,500 cashback but pay an extra $50 per month in interest, the break-even point is 50 months. If you plan to refinance again before that, the cashback works in your favour. If not, you're paying for it several times over.
3. Check the Clawback Period
Most cashback offers include a clawback clause, which means you'll need to repay the cashback if you refinance or discharge the loan within a set period, usually between 12 and 24 months. The clawback is typically proportional to how much of the period remains. If you refinance after 18 months on a 24-month clawback, you might need to repay half the cashback.
This matters for teachers who might need flexibility. If you're planning to move interstate for a new role, buy an investment property, or consolidate debt within the next two years, a clawback clause could lock you into a loan that no longer suits your circumstances. Read the fine print before committing.

4. Understand What Features You're Trading Off
Some cashback loans lack offset accounts, redraw facilities, or the ability to make extra repayments without penalty. These features can save you thousands in interest over time, far exceeding the value of a one-off cashback payment. An offset account on a $400,000 loan with $20,000 sitting in it saves roughly $1,400 per year in interest at a 7% rate.
If a cashback offer requires you to move from a loan with an offset to one without, calculate what that offset is currently saving you. For high school teachers with regular pay cycles and the ability to build a buffer, losing an offset account is often more costly than the cashback is worth.
5. Factor in the Cost of Refinancing
Refinancing costs typically include a discharge fee from your current lender, an application fee for the new loan, a valuation fee, and sometimes settlement or legal fees. These can add up to $1,500 to $2,500 depending on your lender and location. Cashback is designed to cover these costs, but if the offer is only $1,000 and your costs are $2,000, you're still out of pocket.
Some lenders waive application fees or cover valuation costs as part of the refinance package. Compare the total cost of switching, including any fees not covered by cashback, before deciding whether the offer represents genuine value.
6. Look at the Comparison Rate, Not Just the Advertised Rate
The comparison rate includes the interest rate plus most fees and charges, expressed as a single percentage. It's a more accurate way to compare loans because it accounts for upfront costs that the advertised rate ignores. A loan with a 6.50% interest rate and high fees might have a comparison rate of 6.75%, while a loan at 6.60% with low fees might have a comparison rate of 6.65%.
Cashback isn't included in the comparison rate calculation, so you'll need to factor it in separately. If two loans have similar comparison rates but one offers $2,000 cashback, that's a genuine advantage, assuming the clawback period and features align with your plans.
7. Assess Whether You Actually Need the Cash Now
Cashback is most useful when you need funds for a specific purpose, such as covering the upfront costs of refinancing, paying down other debt, or managing an unexpected expense. If you don't have an immediate use for the cash, it might make more sense to prioritise a loan with a lower rate or stronger features that deliver long-term savings.
For instance, a teacher refinancing to access a lower rate who doesn't need the cashback might save $1,200 per year by choosing a loan 0.30% cheaper than the cashback option. Over five years, that's $6,000, which outweighs a $2,000 cashback by a significant margin.
8. Consider the Loan's Flexibility Beyond the Cashback
Flexibility includes the ability to split your loan between fixed and variable, make unlimited extra repayments, port the loan to a new property, or switch between repayment types without penalty. These features matter more over time than a one-off payment. A mortgage for teachers that offers genuine flexibility allows you to adapt as your circumstances change without needing to refinance again.
In our experience, teachers who prioritise flexibility over cashback tend to stay with their loan longer and avoid the costs of refinancing multiple times. If a cashback offer locks you into a rigid product, weigh whether that trade-off is worthwhile.
9. Check if the Cashback is Conditional on Loan Size
Some lenders tier their cashback offers based on loan size. You might receive $2,000 for refinancing $250,000 to $499,999, but $4,000 for refinancing $500,000 or more. If you're close to a threshold, it might be worth borrowing slightly more to access the higher cashback, but only if the additional borrowing serves a genuine purpose, such as debt consolidation or accessing equity for a clear goal.
Borrowing more than you need just to qualify for a higher cashback is almost always a poor financial decision. The extra interest on the additional borrowing will exceed the cashback within a few years, and you'll be paying off a larger loan for decades.
10. Run the Numbers on Your Actual Loan Before Committing
Every refinance decision should be based on your specific loan amount, interest rate, remaining term, and financial goals. A cashback offer that works well for someone refinancing $600,000 might not suit someone refinancing $350,000, even if they're both high school teachers with similar incomes.
As an example, a teacher refinancing $380,000 with 25 years remaining who receives $2,500 cashback but moves to a rate 0.20% higher than a comparable non-cashback loan will pay an extra $760 per year in interest. The cashback is absorbed within four years, and after that, they're paying more for no ongoing benefit. If they'd chosen the lower rate without cashback, they'd save $19,000 over the remaining term.
A home loan refinancing for teachers should be assessed on the total cost over the period you expect to hold the loan, not just the upfront incentive. Use a calculator or speak to a broker who can model both scenarios with your actual figures.
Cashback offers can be worthwhile when the loan itself is competitive and the cashback covers genuine costs you'd otherwise pay out of pocket. They become expensive when you're paying a higher rate, sacrificing features, or staying with a product longer than the clawback period just to keep the cashback. A loan health check can clarify whether refinancing makes sense for your situation, with or without cashback.

Frequently Asked Questions
How much cashback can I expect when refinancing my mortgage?
Cashback offers typically range from a few hundred dollars to several thousand, depending on your loan size and the lender. Some lenders tier cashback by loan amount, offering more for larger mortgages. The actual value depends on the loan's interest rate, features, and clawback conditions.
What is a cashback clawback period?
A clawback period is a set time, usually 12 to 24 months, during which you must repay some or all of the cashback if you refinance or discharge the loan. The repayment is often proportional to how much of the period remains. Always check the clawback terms before accepting a cashback offer.
Is a cashback loan worth it if the interest rate is higher?
It depends on how long you hold the loan. If the higher rate costs you more in extra interest than the cashback amount within a few years, the offer isn't worthwhile. Calculate the break-even point by dividing the cashback by the extra monthly interest cost to see when the benefit disappears.
Does cashback cover all the costs of refinancing?
Not always. Refinancing costs can include discharge fees, application fees, valuation fees, and settlement costs, which may total $1,500 to $2,500. If the cashback is lower than your total costs, you'll still be out of pocket. Compare the cashback amount to your actual refinancing expenses.
Should I refinance just to get the cashback?
Only if the loan itself is competitive and suits your needs. Refinancing solely for cashback can be costly if the new loan has a higher rate, fewer features, or a clawback period that limits your flexibility. Assess the total cost of the loan over the period you expect to hold it, not just the upfront payment.
