The cashback catch

A four-figure cashback feels like free money, but it's marketing for a reason. Here's how to tell when a cashback is genuinely a good deal and when a sharper rate beats it.

Is a home loan cashback actually a good deal?

Sometimes, but a cashback is a marketing tool, not a gift. A lender offers cash up front to win your loan, then earns it back over the years you stay through the rate you pay. The catch is that the loans with the biggest cashbacks often carry a rate that isn't the sharpest available, so a slightly higher rate over a long loan can quietly outweigh the one-off cash. The only way to know is to compare the cashback against the extra interest you'd pay versus the lowest comparable rate.

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.

What conditions come attached to a cashback?

Cashbacks almost always have strings. Common conditions include a minimum loan size, a minimum LVR or equity position, settlement by a deadline, and a clawback if you discharge the loan within a set period (often one to two years). Read the offer terms, because leaving early can mean repaying the cash. Tax can also apply to a cashback in some circumstances, so check your position.

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.
