Many cafes charge a card surcharge and still lose money. Others cover costs but create compliance risk.
The difference is whether surcharge policy is based on real acceptance cost data, not guesswork.
Quick Summary
- ACCC guidance says card surcharges must not exceed cost of acceptance
- If no surcharge-free payment method exists, displayed pricing must account for surcharge
- RBA review materials continue to examine surcharge outcomes and potential reform directions
- Best practice: card-type cost mapping, capped surcharge matrix, monthly review
Why this matters for small operators
Card usage is high, margins are tight, and “just add 1.5%” is common. But if acceptance costs differ by card type, one blunt surcharge can overshoot for some transactions.
That creates two problems:
- compliance exposure
- customer trust damage
Both are expensive.
The compliance formula
For each payment type:
Maximum compliant surcharge rate <= Cost of acceptance rate
And if you want to quantify potential oversurcharge risk:
Potential overcharge dollars =
(Applied surcharge rate - Acceptance cost rate)
x Card sales volume
If the first term is positive, fix your matrix immediately.
Worked example
Monthly card sales:
- Debit network volume: AUD 42,000
- Credit card volume: AUD 58,000
Actual acceptance costs:
- Debit: 0.7%
- Credit: 1.3%
If the business applies one flat 1.5% surcharge:
Debit overcharge exposure:
(1.5% - 0.7%) x 42,000 = 0.8% x 42,000 = AUD 336
Credit overcharge exposure:
(1.5% - 1.3%) x 58,000 = 0.2% x 58,000 = AUD 116
Total monthly overshoot exposure: AUD 452
Better setup:
- Debit surcharge at or below 0.7%
- Credit surcharge at or below 1.3%
Display-price rule operators miss
If every available payment method carries a surcharge, ACCC guidance indicates the business should include surcharge in displayed prices.
Practical fix:
- confirm if any surcharge-free payment path exists
- if none, update displayed menu pricing logic
- sync signage, POS, and online ordering copy
Policy watch for 2026
RBA review work in 2024-2025 has assessed merchant card costs and surcharge outcomes, including consultation on reform options. Treat this as a watchlist item:
- check official updates quarterly
- avoid hard-coding long-term surcharge assumptions without policy review
Checklist
- Acceptance cost by card type documented
- Surcharge matrix capped by payment type
- Display-price rule checked for surcharge-free options
- POS + menu + online wording aligned
- Quarterly policy-watch review added
