Australia's surcharge ban: calculate the cost after recovery stops

Australia’s announced no-surcharge rules begin on 1 October 2026 for eftpos, Mastercard, Visa, American Express and UnionPay, and on 5 October 2026 for PayPal. They change what merchants may recover from customers, not whether payment providers charge for accepting cards. Networks and merchant contracts implement the change; provider terms and applicable exceptions still need checking.

For a business preparing for the change, compare card-processing expenses with the surcharge dollars actually recovered. Those amounts need not be equal. If you currently pay A$1,800 a month and recover A$1,000, your net card cost is already A$800—not zero.

Use the calculator and worked examples to compare the cost before and after recovery stops; they do not authorise a surcharge. The amounts are hypothetical, not typical industry rates, and do not calculate GST or determine a lawful surcharge limit. Rule information was checked on 2026-09-14, before the announced changes take effect.

Keep actual fees and recovered surcharges on separate lines

Take one comparable period from your records. Enter the underlying card sales before customer surcharges, the surcharge dollars actually collected, and the actual acceptance expenses for that period. Use a consistent basis for the before-and-after comparison; do not mix a monthly fee with annual sales.

The ACCC’s card-surcharge guidance explains that provider statements show acceptance costs and that additional claimed costs need verifiable records. The calculator’s effective recovery rate is simply recovery divided by base card turnover. It is not your processing rate or a legal maximum.

Here is a hypothetical month with A$100,000 in underlying card sales:

The business’s provider bill falls by A$150, yet its net cost rises by A$850. It loses A$1,000 of recovery while saving only A$150 on expenses. The effective current recovery rate is 1% of the A$100,000 base turnover, independently of the separate 1.5% single-payment example.

The useful bridge is:

Change in net cost = future expenses − current expenses + lost recovery.

Here that is A$1,650 − A$1,800 + A$1,000 = A$850. If you currently recover nothing, the same fee reduction instead lowers your net cost by A$150. The starting business model changes the result.

A negative current net cost means the entered recovery exceeds the entered expenses. It is a reason to check the period, definitions and compliance—not something to hide by forcing the result to zero. The arithmetic cannot validate the charging practice.

Which dates and payment types matter?

According to the RBA’s current implementation FAQ , the announced scope includes:

This is a summary of the named announcements, not an exhaustive list of payment services. The rules and any exceptions need checking with your provider. The RBA removes its prohibition on network no-surcharge rules; networks and merchant contracts implement them. It is not direct RBA regulation of each shop.

The industry business FAQ coordinated by AusPayNet explains that designated-network transactions include in-store, online and mobile-wallet payments. Paying as a business does not itself create an exemption. Taxi surcharging and other exceptions require the relevant legal or network provisions to be checked.

Until 2026-09-30, the current cost-based rules still matter. For regulated payment types, a common surcharge across types cannot exceed the lowest permitted type-specific amount; averaging debit and credit costs does not establish permission. Nor does renaming a card-linked charge make it a different kind of fee. After the applicable change, a statement showing acceptance costs is not, by itself, permission to keep recovering them through a surcharge.

A smaller provider bill is different from a smaller burden

Removing a separate surcharge changes how a payment cost is recovered. It does not, on its own, remove the service of accepting the payment or the provider’s bill. That distinction explains why the reform can reduce one expense while increasing the merchant’s net cost in the worked example.

The burden can remain in the business’s margin, reach customers through overall prices, or be partly offset by a better payment plan. Which happens depends on actual provider charges, competition and the business’s ability to change prices without losing sales. The example isolates the payment-cost change; it does not forecast sales, margins or a suitable price increase.

The RBA also has reforms intended to reduce acceptance costs, including lower domestic interchange caps from 2026-10-01. Interchange is only one part of the merchant bill. The policy objective is therefore a reason to examine a new quote or statement, not to enter an assumed saving as a fact. Run an unchanged-fee case as well as any quoted reduction.

This is also why a positive A$850 cost change is not proof that every merchant loses or that the reform fails. A business that never surcharged starts from a different position. A provider reduction large enough to offset lost recovery produces another result. Follow the separate cash amounts rather than assigning one outcome to all businesses.

For the household, compare the same basket’s final price

A missing surcharge line is visible. A change in the underlying price can be less obvious. If the same basket previously cost A$100 plus A$1.50, these hypothetical outcomes are all possible:

These are scenarios, not predictions of what shops will do. Keep the basket and quantities identical when comparing. Otherwise a different purchase can look like a price effect.

For a household budget , the relevant saving is the reduction in the amount actually paid—not the old surcharge multiplied across future purchases regardless of their prices. For a merchant, the same distinction prevents a lost recovery line from being mistaken for the whole cost of accepting cards.

Historical surcharge arithmetic, if you need it

For a historical or permitted pre-change payment, multiply the price before the surcharge by the surcharge rate. A$100 at 1.5% adds A$1.50, making the customer’s total A$101.50. That calculation does not establish whether you are allowed to charge it.

Use these two steps for the single-payment example:

• Surcharge = A$100 × 1.5 ÷ 100 = A$1.50.

• Customer total = A$100 + A$1.50 = A$101.50.

If A$101.50 already includes the surcharge, entering that as the starting price adds the charge again. To recover the original base in this example, divide A$101.50 by 1.015, giving A$100. Entering the inclusive total instead would calculate another A$1.52 and show A$103.02.

Keep that single payment separate from the whole month’s figures. A sample 1.5% transaction does not mean every customer paid 1.5%, or that your provider charged the same percentage.

Take three figures to your payment provider

Before changing your forecast, gather current acceptance expenses, actual surcharge recovery and a like-for-like future fee quote for the same period. Ask which fees change, when they change and whether the quote covers your transaction mix and terminal or gateway costs.

Then confirm how the provider will remove applicable surcharges across terminals and online checkout. Update customer-facing pricing and test the payment flow before the relevant date. Do not assume a terminal change also fixes every gateway, invoice or checkout setting.

Use the calculated net-cost change to understand the size of the adjustment. Use current provider terms and official guidance to establish what charging practices are permitted. They answer different questions, and neither should be substituted for the other.
