The $18k trap: could a rewards card leave you out of pocket?
Qantas points this, Velocity points that. The world of airline rewards points, and credit card rewards more broadly, is vast—but does it offer value? When used wisely, rewards credit cards can provide you with some nice little perks. If you do your everyday spending on a rewards card, you may be able to ‘earn’ points to put towards discounts at the checkout or airfares for your next holiday.
But if used carelessly, rewards cards can cost you a lot more than you bargained for. If you don’t pay off your balance each month, interest charges could eat up the value of your perks. Likewise, if you sign up for a rewards card but don’t spend enough to get access to the perks, you could find yourself giving money away in fees.
Assuming you’re the perfect credit card holder, dutifully paying off your balance each month, a reward card’s worth may simply come down to how much you spend on it. So how much do you need to spend to realise true rewards?
How much do you have to spend for a rewards card to be worth it?
There’s no magic number that you have to spend to make a rewards card pay for itself. If you want to know whether a rewards card is worth it for you, you could apply the following formula and do the maths yourself:
- Add up the costs of owning the card, including annual fees
- Determine your average annual spend
- Figure out how the value of any rewards you might earn
- Weigh the costs against the benefits and make your final decision
Canstar Research ran two case studies to show how two people with different spending habits could benefit (or lose out) on a rewards credit card. The findings showed a person spending $18,000 could actually lose money by taking out a rewards card, while another swiping on $36,000 worth of purchases could be more than $200 better off.
Frequent flyer credit cards: a case study
Olivia and Taylor are both keen travellers, and both signed up for the same rewards card, with the aim of earning Qantas points to put towards flights. The card has an annual fee of $250.13 and earns one Qantas point per dollar spent. Both pay off their statement in full each month, so neither is charged interest.
Olivia spends $36,000 annually on her credit card, whereas Taylor spends $18,000. At the end of one year, Olivia finds herself with a net benefit of $230 whereas Taylor finds herself behind by $10. This means Olivia can stick with her plan of putting her rewards points towards flights and score herself a discount, but Taylor will be worse off.

| Olivia | Taylor | |
|---|---|---|
| Annual spend | $36,000 | $18,000 |
| Qantas points earned per $1 spent | 1 | 1 |
| Total Qantas points earned | 36,000 | 18,000 |
| Value per Qantas point | $0.01334 | $0.01334 |
| Dollar value earned | $480.24 | $240.12 |
| Annual card fee | $250.13 | $250.13 |
| Annual net benefit | $230.00 | -$10.01 |
Canstar Research estimates that Qantas Points are worth approximately $0.01334 each when redeemed for flight reward seats (as opposed to wine or other available rewards). This calculation is based on a range of flight routes, dates, and seat types, comparing the cash value of each flight against the number of points required to redeem it. Flight quotes were collected for dates ranging from October 2025 to July 2026.
Of course, it’s worth keeping in mind that frequent flyer points are only part of the picture, and are not the only perk offered by premium rewards credit cards. Some cards come with a variety of perks like complimentary travel insurance, airport lounge passes, and even annual travel credits. If you’re a frequent traveller and tend to pay your balance off on time, these perks can come in extremely handy, and can more than outweigh the annual fees.
Additionally, different rewards programs may offer better value for some purchases over others. For instance, a person redeeming their points for a flight might be able to afford a higher-value service in return for a certain number of points than another redeeming their points for a toaster.
Are rewards credit cards really worth it?
If you’re pondering whether to sign up for a rewards card, or even looking at your current one and wondering if it’s still cutting the mustard, it pays to ask yourself a few questions.
Will you carry a balance on the card?
Rewards cards tend to have the highest interest rates of all credit cards, hovering around 20.99% p.a. at the big four banks. If you don’t pay off your balance in full with each statement, you might be eating into the value of your rewards. If you’re the type to carry a balance on a credit card, then a rewards card may not suit your needs.
Is the sign-up bonus worth it?
Some rewards credit cards offer bonuses tied to your spend–for example, 50,000 Qantas points if you spend $5,000 in the first three months. Offers like this can be worthwhile if you normally spend at such a level and can comfortably pay your balance off. If not, your reward points could end up costing you more than you bargained for in credit card interest.
What are the rewards worth to YOU?
Some rewards may not be worth a lot for you. A card that rewards you with Qantas points won’t mean much if you don’t plan on flying Qantas. On the other hand, some cards may offer bonus points for spending at specific places, like petrol stations. If you already fill up there, then the extra rewards could make a meaningful difference to you.
Are you just chasing the rewards?
Credit card rewards can be appealing, but taking out a card just to chase the rewards can lead to reckless spending. If you do take out a rewards card, don’t spend more than you normally would just for the sake of chasing points, lest you find yourself drowning in debt without a lot to show for it.
Are credit card rewards changing in Australia?
The Australian credit card landscape will likely see big changes in the next few months. From 1 October 2026, the Reserve Bank of Australia (RBA) is banning surcharges on credit and debit payments across the eftpos, Mastercard, and Visa network.
While it’s unclear how banks will respond, there’s speculation that we may start to see credit card fees go up and rewards points programs scaled back to make up for lost earnings. We may even see some new players enter the field with different kinds of offerings.
Global fintech Revolut is currently trying to woo spenders with a rewards debit card. Revolut’s Ultra plan comes with a hefty monthly fee of $99.99 (or $999 annually) and offers rewards points for spending on debit, rather than credit cards.
Will any Australian banks follow suit and begin offering rewards debit cards of their own? This remains to be seen. But in the meantime, it’s worth doing an audit of your rewards credit card to see if you’re still getting value for money.
