The Surcharge Dilemma

You tap to pay and the screen offers a choice: card with a 1.5% surcharge, or debit/bank transfer free. Whether the surcharge is worth paying is pure arithmetic — and most people get it wrong because they think in points instead of cents.

The Breakeven Formula

Paying a surcharge makes sense only when:

earn rate × value per point > surcharge percentage

Take the Qantas Premier Platinum at 1.25 pts/$. At our mid-range Qantas valuation of 1.4¢/pt, that's a 1.75% return — so a 1.5% surcharge clears the bar with a thin 0.25% margin. At a pessimistic 1.0¢/pt redemption, the same card returns 1.25% and the surcharge loses you money. The ANZ Explorer at 1.5 pts/$ and ~1.6¢/pt returns ~2.4%, comfortably beating surcharges up to 2%.

Worked Examples

  • 1.0% surcharge (common at large retailers): almost always worth paying with a decent points card — even a 1% cashback card breaks even.
  • 1.5% surcharge (typical for Amex at smaller merchants): marginal. Only worth it with high earn rates and high-value redemptions.
  • 2.5%+ surcharge (some taxis, small business): almost never worth it. Use a debit card and keep the points card for surcharge-free spend.
  • Government payments (ATO, council rates): many cards earn reduced or zero points here, and the surcharge applies anyway. Check your card's government-payment earn rate before paying a tax bill for points.

Don't Forget the Other Side of the Ledger

The breakeven assumes you'd redeem the points at the stated value. If your actual redemptions drift toward gift cards (under 0.6¢/pt), no surcharge is worth paying — switch to the Westpac Platinum Cashback and let its guaranteed 1% answer the question for you. Our points valuation guide helps you find your honest redemption value.

The Rules Around Surcharging

Australian law bans excessive surcharging: merchants may only pass on their actual cost of acceptance. If a flat "$5 card fee" or a 3% surcharge looks well above cost, it may breach the rules — the ACCC takes complaints. And remember the golden rule underneath all of this: surcharge maths only matters if you pay in full. One month of carried interest wipes out a year of surcharge-optimised points.
