A cashback offer pays you a lump sum when you refinance your mortgage to a new lender.
These offers typically range from a few hundred dollars to several thousand, depending on your loan amount and the lender's current promotion. They sound attractive, and in some circumstances they are, but the cash in your hand at settlement is only part of the calculation. The interest rate, ongoing fees, and loan features you end up with matter more over the life of the loan.
How Cashback Offers Actually Work
Cashback is paid after your new loan settles, usually within a few months. The amount is either a flat figure or calculated as a percentage of your loan amount. Most offers sit between $2,000 and $4,000 for residential home loans. The lender pays the cashback directly into your nominated account, not into your mortgage offset or redraw.
Some lenders attach conditions. You might need to stay with them for a minimum period, often two to four years, or repay the cashback if you exit early. Others require you to hold both a variable rate loan and an offset account. Read the terms carefully before you commit.
When Cashback Covers the Cost of Switching
Refinancing costs typically include discharge fees from your current lender, application fees with the new lender, valuation fees, and sometimes settlement or legal fees. These can add up to $1,500 to $3,000 depending on your lender and state.
Consider a primary teacher refinancing a $450,000 mortgage. If the discharge fee is $350, the new lender charges $600 for the application, and valuation comes in at $250, the total cost is around $1,200. A $3,000 cashback offer covers those costs and leaves $1,800 in hand. But if the new loan has an interest rate 0.15% higher than what you could access elsewhere, you will pay roughly $675 more per year in interest. Over three years, that $1,800 advantage disappears.
Cashback makes sense when it offsets switching costs and the new loan also delivers a lower rate or features that improve your cashflow.

Refinancing for Rate First, Cashback Second
Your ongoing interest rate has a far larger impact than a one-time payment. A reduction of 0.25% on a $450,000 loan saves you around $1,125 per year. Over five years, that is more than $5,500, which outweighs most cashback offers.
In our experience, teachers often focus on the upfront cashback and overlook the comparison rate or the ongoing account fees. The comparison rate includes most fees and gives a closer picture of what the loan actually costs. If the cashback offer comes with a higher comparison rate than another option, the cashback is unlikely to leave you ahead in the medium term.
Start by identifying lenders offering a lower interest rate than your current one, then see which of those also offer cashback. Do not reverse the order.
Clawback Clauses and Early Exit Penalties
Most cashback offers include a clawback clause. If you refinance again or pay out the loan within a set period, you repay all or part of the cashback. This period is usually two to four years.
If you plan to sell your property, upsize, or release equity to buy an investment property in the next few years, a cashback offer with a long clawback period could cost you money. Check whether paying down extra principal or redrawing funds triggers the clawback. Some lenders are stricter than others.
What to Compare Alongside the Cashback
Once you have confirmed the interest rate is competitive, compare the offset account functionality, redraw availability, and whether the lender allows extra repayments without penalty. Teachers in casual or contract roles often benefit from redraw flexibility during school holidays or term breaks when income can fluctuate.
Some cashback offers require you to take a package with an annual fee. If that fee is $395 per year and you stay for three years, you will pay nearly $1,200 in fees. Subtract that from the cashback figure to see what you actually receive.
Also confirm whether the lender allows you to split your loan between variable and fixed rates. If your fixed rate period is ending, refinancing with a split structure and a cashback offer can give you rate certainty on part of the loan while still allowing access to offset benefits on the variable portion.
Using Cashback to Cover Immediate Costs or Reduce Debt
If refinancing saves you money on interest and the cashback offer has no clawback risk, you can use the funds to pay down other debt, cover moving costs, or add to an offset account. Putting the cashback into your offset account reduces the interest charged on your mortgage from day one, which compounds the benefit of refinancing.
Some teachers use cashback to clear smaller debts like car loans or credit cards, which often carry higher interest rates than a mortgage. That approach works if the mortgage refinance itself does not increase your overall interest costs.

Frequently Asked Questions
How much cashback can I expect when refinancing my home loan?
Cashback offers typically range from $2,000 to $4,000 for residential home loans, with the amount sometimes calculated as a percentage of your loan amount. The exact figure depends on the lender's current promotion and your loan size.
Do I have to repay the cashback if I refinance again?
Most cashback offers include a clawback clause requiring you to repay all or part of the cashback if you exit the loan within a set period, usually two to four years. Check the terms before committing.
Is cashback worth it if the interest rate is higher?
Not usually. A higher ongoing interest rate will cost you more over time than a one-time cashback payment. Prioritise finding a lower rate first, then look for cashback among competitive options.
When is cashback paid after refinancing?
Cashback is typically paid within a few months after your new loan settles. The funds are deposited into your nominated account, not into your mortgage offset or redraw.
Can I use cashback to pay off other debts?
Yes, you can use cashback however you like once it is paid. Some borrowers use it to clear higher-interest debts like car loans or credit cards, or deposit it into an offset account to reduce mortgage interest.
