The $10 Coffee That Becomes $11: The Hidden Inflation of Australia's Surcharge Ban
Key takeaway
From 1 October 2026, Australian merchants will no longer be able to add card payment surcharges to eftpos, Visa and Mastercard transactions. American Express has also announced that it will voluntarily remove surcharging options.
That sounds like an immediate win for consumers. The Reserve Bank of Australia estimates that consumers will avoid around $1.6 billion in annual surcharges, while businesses should benefit from approximately $910 million in lower card acceptance costs through interchange reform.
But there is a less comfortable possibility.
The cost of accepting cards is not disappearing. It is being redistributed. For merchants operating on already-thin margins, the choice may be to absorb the cost, reduce investment, or increase prices for everyone.
And businesses will not necessarily move a $10.00 item to $10.09. They may move it to $10.50 or $11.00 because menus, catalogues and checkout systems are built around commercially useful price points.
That is the hidden inflation risk: not a precise pass-through, but a behavioural one.
What happens after 1 October?
The reform removes card payment surcharges on designated card networks. Merchants will no longer be able to show a separate “card surcharge” line for eligible debit, credit and prepaid card payments.
The ban does not remove:
Merchant service fees
Terminal and payment provider fees
Fraud and dispute costs
Scheme fees
The operational cost of accepting digital payments
The RBA’s frequently asked questions are clear: businesses will still incur card acceptance costs, but those costs can be reflected in overall pricing rather than charged as a separate surcharge.
The reform also changes the economics underneath the transaction:
The domestic consumer credit interchange cap falls from 0.8% to 0.3%
Debit interchange is capped at 8 cents per transaction or 0.16%
The commercial credit cap remains at 0.8%, with existing benchmarks abolished
Foreign-issued card interchange will be capped at 1.0% from 1 April 2027
These reductions should lower the cost of card acceptance for many merchants. However, they do not necessarily compensate every business for losing the ability to charge card users directly.
Only around 16% of merchants currently surcharge, according to RBA-related reporting. That group is concentrated in small retail, hospitality and service businesses : precisely the businesses most exposed to labour costs, rent, utilities and narrow operating margins. Surcharging has also reportedly doubled since 2022.
For those merchants, the reform is not simply about removing a fee. It changes the pricing model.
The cost that did not go away
Consider a $5.00 flat white with a 1.5% card surcharge.
Before the ban:
Cash customer: $5.00
Card customer: approximately $5.08
Merchant: recovers the card acceptance cost from the customer using the card
SmartCompany’s analysis, including commentary from accountant Natalie Lennon, highlights the next step. If approximately 85% of transactions are made by card, the café must recover the blended cost across almost every sale if it wants to protect its margin.
The result might be a new menu price of approximately $5.10 for everyone.
The cash customer now pays more, despite not creating a card processing cost. The debit customer pays more, even though debit may be cheaper for the merchant than a premium rewards credit card. The card customer avoids the visible surcharge, but the underlying cost has been embedded in the product price.
This is not a criticism of merchants. It is a predictable commercial response.
The RBA has previously acknowledged that when payment costs are incorporated into general prices, users of more expensive payment methods can effectively receive a subsidy from customers using cheaper methods.
The surcharge ban makes that cross-subsidy less visible.
The rounding problem: $10.00 does not become $10.09
The official economic modelling generally assumes a relatively clean pass-through. If the merchant’s blended additional cost is 0.9%, a $10.00 product becomes $10.09. If the cost is 1.5%, it becomes $10.15.
Real businesses do not always price that way.
Menus and price lists are built around price points such as:
$9.95
$10.00
$10.50
$11.00
$12.00
A merchant may decide that $10.09 is awkward for a menu, creates unnecessary coins, complicates staff conversations or looks less commercially attractive than $10.50.
That creates a potential rounding tax.
For example:
Scenario one: precise recovery
A $10.00 item increases to $10.10.
The merchant recovers a modest amount from every customer. The price remains close to the original point, and the impact may be difficult to notice.
Scenario two: menu simplification
The merchant decides that $10.10 is an unattractive menu price and moves the product to $10.50.
The underlying payment cost may justify only a few cents, but the displayed price has increased by 50 cents : a 5% increase.
Scenario three: psychological price positioning
The business is already reviewing prices, supplier costs and margins. It moves the item from $10.00 to $11.00, a 10% increase, because $11.00 is easier to communicate and aligns with other products.
The surcharge ban did not mathematically require a dollar increase. But it may become one factor in a broader repricing decision.
This is why the $10 coffee becoming an $11 coffee is best understood as a risk scenario, not a universal forecast.
What this means for merchants
The most exposed businesses are those with:
High card transaction volumes
Low average transaction values
High proportions of premium credit card payments
Limited negotiating power with acquirers
Already-skinny margins
Menus or catalogues that rely on simple price points
A café might recover a few cents per transaction in theory. But across thousands of transactions, even a small margin change matters. If the business absorbs the cost, annual profit falls. If it raises prices, it risks losing price-sensitive customers.
Hospitality bodies have been warning about this outcome. The Australian Restaurant and Cafe Association argues that menu prices will rise and that cash customers will be among the biggest losers. Its position is commercially understandable: the merchant still has to pay to accept the card.
The competitive challenge is that price increases are not isolated. Consumers are already comparing cafés, restaurants and retailers through delivery apps, online menus and search results. A 50-cent increase may appear small in isolation but material when it occurs across a weekly basket of purchases.
The RBA’s March 2026 conclusions also recognise that some merchants may increase advertised prices after surcharging is removed.
What this means for inflation
The RBA estimates the net inflation impact at approximately 0.1%, a small one-off effect. That estimate may be reasonable if merchants pass through costs precisely and if lower interchange fees offset much of the change.
The problem is that pricing is not conducted by spreadsheet alone.
There are two different inflation questions:
Perceived inflation: What customers feel when a familiar coffee, lunch or service becomes more expensive.
Measured inflation: What statistical agencies record when the displayed price of a product or service rises.
A $10.00-to-$10.09 increase is economically modest. A $10.00-to-$10.50 increase is much more noticeable. A $10.00-to-$11.00 increase is a clear price reset.
If enough merchants use the reform as a trigger to simplify price points, rebuild margins or reposition their menus, the measured effect may exceed the pure payment-cost calculation in affected categories. The aggregate CPI effect may still be small, but customers will experience the increase in the places they visit most often.
The RBA’s estimate is therefore not wrong. It is incomplete if it assumes clean and proportionate pass-through.
Who wins and who loses?
Likely winners:
Card users who previously paid visible surcharges
Consumers who prefer simple, all-inclusive prices
Larger merchants with stronger acquiring economics
Acquirers that can offer lower-cost and more transparent pricing
Payment providers that help merchants optimise routing and acceptance costs
Potential losers:
Cash customers who lose access to the lower base price
Small businesses unable to absorb fees
Consumers who rely on cash or low-cost debit
Card issuers facing lower interchange revenue
Rewards customers if banks reduce points and benefits
The Australian Banking Association has supported the surcharge ban while warning about the impact of interchange reductions. Banks may respond through higher annual fees, reduced rewards or changes to card economics.
CommBank, for example, has announced a reduction in its flat merchant service fee from 1.1% to 0.99% for eligible in-store customers from 1 October. Providers such as Tyro are also using pricing offers to compete for merchants.
The direction is clear: the payment cost is moving from a visible checkout line into a broader contest over prices, margins, rewards and acquiring relationships.
What businesses should do now
Merchants should not wait until October to discover the impact in their profit and loss statement.
They should:
Model the true blended cost by card type, channel and transaction value.
Review interchange-plus versus blended pricing with their acquirer.
Negotiate merchant service fees before the deadline.
Support least-cost routing where available.
Reprice deliberately, rather than applying an arbitrary percentage.
Test price points against customer behaviour and competitor pricing.
Communicate the change clearly if prices are adjusted.
Consider lawful discounts for cash or lower-cost payment methods, rather than card surcharges.
The RBA confirms that payment-method discounts remain possible, subject to appropriate pricing and disclosure requirements. Businesses should also review ACCC guidance on price displays and card surcharges.
The strategic take
Australia’s surcharge ban will make prices look cleaner. It will not make payment economics disappear.
The central policy question is whether consumers are genuinely better off when a visible 1.5% surcharge becomes a higher price paid by everyone : and whether official estimates adequately account for the way businesses actually set prices.
The most likely outcome is not that every $10 coffee becomes $11. It is that some businesses absorb the cost, some raise prices by a few cents, and others use the moment to move to a more commercially attractive price point.
That is why merchants, payment executives, fintechs and investors should watch the first few months after 1 October closely. The key signal will not simply be whether prices rise. It will be how they rise : precisely, gradually or in jumps.

Frequently asked questions
When do card surcharges end in Australia?
Card surcharges on eftpos, Visa and Mastercard debit, credit and prepaid transactions end from 1 October 2026. American Express has also announced the voluntary removal of surcharging.
Can businesses raise their prices?
Yes. Businesses can adjust their general prices, provided they comply with applicable consumer law and price-display requirements. They cannot disguise a card surcharge as a general fee simply because a customer pays by card.
Will prices rise more than the underlying payment cost?
They may. The underlying cost might justify a small increase, but merchants may round prices to commercially useful points such as $10.50 or $11.00.
Who pays the cost after the ban?
The cost may be absorbed by the merchant, embedded in prices paid by all customers, or partly offset through lower merchant service fees. In a uniform pricing model, cash customers can effectively subsidise card users.
Will credit card rewards disappear?
Not necessarily, but lower interchange revenue may put pressure on points earn rates, annual fees and card benefits. The impact will depend on each issuer’s economics.
Is the RBA’s 0.1% inflation estimate realistic?
It may be realistic as a broad, one-off macroeconomic estimate. However, it may not capture behavioural effects such as menu simplification, price-point psychology and larger-than-necessary rounding.
