The cashback catch

A four-figure cashback feels like free money, but it's marketing for a reason. How to tell when a cashback wins and when a sharper rate beats it.

Is a home loan cashback actually a good deal?

Sometimes, but a cashback is marketing, not a gift. A lender pays cash up front, then earns it back over the life of the loan through the rate you pay. The loans with the biggest cashbacks often carry a rate that isn't the sharpest, so compare the cashback against the extra interest before deciding.

Which current cashback offers actually beat the market rate?

Today's verified lowest owner-occupier variable rate across 26+ lenders Ratesniffers tracks (November 2026) is 6.18% p.a. Of the lenders currently running a cash offer, here is each one's own verified rate against that benchmark, and on a $500,000 loan over 30 years, roughly how long the rate gap takes to use up the cash. See the full offer register for every current lender campaign, eligibility and end dates.

Lender	Lender's verified rate	Cashback	What the gap costs
Bank of China	6.18% p.a.	$2,500+	At today's market low, cashback is a clean bonus
BCU	6.29% p.a.	$1,500	About 3 years of the rate gap uses up the cashback
Credit Union SA	6.34% p.a.	$2,000	About 3 years of the rate gap uses up the cashback
ANZ	6.79% p.a.	$3,000	About 1 year of the rate gap uses up the cashback

How a cashback can cost more than it pays

Picture two loans of the same size. One pays a cashback but sits a little above the market on rate; the other has no cashback but a sharper rate. The cash lands once; the rate gap repeats every month for as long as you hold the loan. On a large balance held for years, the cumulative rate difference can exceed the cashback. The cashback wins only when the rate is also competitive, or when you genuinely plan to refinance again before the rate gap catches up.

Factor	Cashback loan	Sharper-rate loan
Up-front benefit	Lump sum paid once	None
Ongoing rate	Often slightly higher	Lowest comparable
Best for	Covering switching costs now	Long-term hold
The risk	Higher rate outlasts the cash	No instant reward

What conditions come attached to a cashback?

Treat a cashback as a tiebreaker between two already-sharp loans, not as a reason to accept a higher rate.

Compare the cashback against the extra interest versus the lowest comparable rate.
Check the minimum loan size, LVR, and settlement deadline.
Watch for a clawback if you refinance or repay early.
A cashback only wins when the rate is also competitive.
