Restaurants pay a published 2.4%–3.09% plus 0–20¢ per transaction to accept cards in 2026 — but that is not what you actually pay. The percentage is charged on the full ticket, tip and sales tax included, so a $100 dinner that leaves as a $128 charge costs $3.35 at a "2.5% + 15¢" rate: 3.35% of your food revenue. Layer on the statement junk fees an audit typically finds and a "2.5%" account clears 3.2% or more. For a restaurant doing $50,000 a month on cards, the processing line runs about $17,250 a year — which is why operators consistently rank it just behind food and labor, and why one Pennsylvania brewpub owner told reporters he paid $40,000 in a single year.
Nearly everything ranking for this question is written by a company that sells payment processing, so the numbers stay vague and the advice ends in a sales call. We did it the RestroScout way instead: on August 5, 2026 we read the published rates off Square's and SpotOn's own pricing pages in a fully rendered browser, dated Toast's rates to our July 25 in-browser verification (its pricing page no longer prints a rate — that's a finding in itself), confirmed that Clover's rate template still fails to render a number at all, and ran the arithmetic none of them show. Everything is recorded in our verification log; nothing is estimated.
If you're pricing a whole POS platform rather than dissecting the processing line, start with our restaurant POS system cost guide — this page goes deep on the one line item that outspends the software 29 to 1.
The rate on the page vs. the rate you pay
The single most useful thing to understand about processing is that the advertised percentage and your effective rate are different numbers, for three stacked reasons.
1. The fee applies to tip and tax. Processors charge on the amount that hits the card. Price out a $100 food-and-drink check with 8% tax and a 20% tip — a $128 charge:
| Published rate | Fee on the $128 charge | Effective rate on your $100 sale |
|---|---|---|
| Square Premium 2.4% + 15¢ | $3.22 | 3.22% |
| SpotOn Essentials 2.45% + 15¢ | $3.29 | 3.29% |
| Square Plus 2.5% + 15¢ | $3.35 | 3.35% |
| Square Free 2.6% + 15¢ | $3.48 | 3.48% |
| Toast Pay-as-you-Go 3.09% | $3.96 | 3.96% |
The tip goes to your team and the tax goes to the state — but the fee on both stays with you. On a tipped full-service check, roughly a quarter of your processing bill is fees on money that was never yours.
2. Not every card gets the headline rate. SpotOn's Essentials page is unusually honest about this: 2.45% + 15¢ — "except Amex: 3.19% + 15¢." That 0.74-point Amex premium costs $74 a month per $10,000 of Amex volume. Keyed-in transactions run higher everywhere (SpotOn 3.45–3.79% + 15–20¢; Square manual entry 3.5% + 15¢), and online orders carry their own tier (Square online: 2.9–3.3% + 30¢ — the number that matters for your online ordering channel).
3. Fixed fees hit small checks hardest. A 15¢ fixed fee is 0.4% of a $40 dinner check but 1.25% of a $12 cafe ticket. If your average check is small, the "+ 15¢" matters more than a tenth of a point on the percentage.
Published rates, verified
The comparison table above holds every figure a vendor actually publishes, read on August 5. Three findings deserve narration.
Square is the transparency benchmark. Full rate card in plain HTML: card-present 2.6/2.5/2.4% + 15¢ by plan tier, online 3.3/2.9% + 30¢, manual 3.5% + 15¢, ACH 1%, even "Bitcoin payments: 0% until 2027." You can price your whole volume without talking to anyone.
Toast stopped printing its rate. On July 25 its pricing page stated plainly: Pay-as-you-Go is "a 3.09% card processing fee [that] covers all costs," Traditional "includes a 2.49% card processing fee." As of August 5 the page — "last updated July 8, 2026" — describes Pay-as-you-Go only as "an all-in-one platform rate," number omitted. We cite the July figures, dated, and note the disappearance. When a vendor removes a price from public view, assume the quoted version is negotiable.
Clover still publishes nothing readable. Its pricing page renders "Pay as little as + per transaction" — with the number literally missing from the template — and the full-service-dining pricing link 404s. Same result as our July 29 check. Lightspeed and TouchBistro set rates in your quote and publish none.
Flat rate vs. interchange-plus
Every rate above is flat-rate pricing: one blended percentage regardless of which card is presented. The alternative — interchange-plus — passes through the card networks' actual wholesale cost (interchange, published by Visa and Mastercard in long category tables) plus a fixed processor markup.
The honest trade: flat rate is predictable and auditable in one line; interchange-plus is usually cheaper at volume because you stop paying rewards-card prices for debit-card swipes, at the cost of a statement only an accountant could love. A useful rule from the operators' side of the fence: below roughly $15–20k/month on cards, the simplicity of flat rate is worth more than the spread; above it, get an interchange-plus quote and make your flat-rate processor beat it. (POS-bundled processors mostly won't unbundle — see the lock-in section below — which is itself information about where their margin lives.)
What the June 2026 settlement changes
The backdrop moved this summer: on June 9, 2026, Judge Brian Cogan granted preliminary approval to the roughly $38 billion Visa/Mastercard swipe-fee settlement. The reported terms that matter for restaurants: average interchange drops about 0.1 percentage point over five years, standard consumer-card interchange is capped at 1.25% for eight years, merchants gain the right to surcharge up to 3% at the brand or product level, and the honor-all-cards rule loosens so you can decline some card categories rather than accepting every card or none. Retail trade groups still call the terms inadequate, and final approval is pending.
Keep the win in proportion: 0.1pp on $50,000/month is about $600 a year. Meaningful, automatic, and much smaller than what the next section typically recovers. Also note the cap applies to interchange — if you're on flat-rate pricing, whether your processor passes the cut through is between you and your contract.
The junk-fee audit
The percentage is only half your statement. Line-item audits of merchant statements (BAMS publishes a good line-by-line guide) consistently turn up the same recurring charges, and the industry ranges they report are worth printing: PCI non-compliance fees of $20–$100/month (a penalty for not completing a free annual questionnaire), statement fees of $10–$25/month, batch fees of 10–25¢ per daily settlement, monthly minimums, and "regulatory" or "technology" fees of $5–$50/month. None of these are card-network costs; all of them are processor margin.
The arithmetic case for spending 30 minutes on this: $100/month of junk fees on $30,000/month of card volume moves your effective rate from 2.88% to 3.21% — a rate hike nobody announced. The audit itself: pull 3–12 months of statements, divide total fees by total volume for your true effective rate, then chase every line that isn't the advertised percentage. The PCI non-compliance fee alone usually disappears with one completed questionnaire.
Flat-rate POS processors like Square largely don't play this game — their published rate is the whole bill, which is a genuine argument for them at low volume even when the headline percentage looks higher.
Surcharges and cash discounts: the actual rules
Passing the fee to the customer has gone mainstream — and it is more regulated than most of the blog posts ranking above this one admit. The rules that actually bind, per the network rule summaries and the 2026 state-law guides (ebizcharge, PaymentCloud):
- Credit only, capped at 3% (Visa; Mastercard's cap is 4%, so 3% is the effective ceiling if you take both) — and never more than your actual cost of acceptance. Debit and prepaid cards cannot be surcharged, even when run as "credit."
- The over-recovery trap is real arithmetic. A flat 3% surcharge on our $128 check collects $3.84 against a $3.35 actual cost at 2.5% + 15¢ — a 49¢ over-recovery on every such check, which network rules prohibit. If your true cost is 2.6%, your lawful surcharge is 2.6%, not "the 3% everyone charges."
- State wrinkles persist: Connecticut, Massachusetts, Maine, and Puerto Rico ban surcharging; Colorado caps it at 2%; New York requires the with-card price to be displayed as a total price, not a fee added at the register. Card brands also require advance notification and receipt disclosure.
- Cash discounting (posting card prices and discounting for cash) and dual pricing are the legally cleaner cousins and are how many POS "zero-fee processing" programs are structured. Same math, different label, fewer state-law problems — but the menu display rules still apply.
And one number before you post the sign: readers and diners report overwhelming irritation at card fees — 87% in one survey said fee add-ons feel like being nickel-and-dimed. A 3% surcharge is a real price increase to your guests; weigh it against simply raising menu prices 2%, which recovers most of the same margin without a sign at the register.
The tip problem
Two separate tip issues hide in the processing line. First, as shown above, you pay the percentage on the tip itself — on a 20% tip, a 2.5% rate quietly costs you half a point of food revenue. Second, some operators recover that by deducting the processing share from staff tips — a practice that is legal under federal law in some circumstances, restricted or banned in several states, and radioactive for morale either way; Philadelphia has seen legislation proposed specifically to stop it. If you're considering it, get state-specific legal advice first and price the turnover risk honestly — it is rarely worth $3.35 a table.
How to actually cut the bill
In order of expected return:
- Compute your true effective rate. Total fees ÷ total card volume, from the last full statement. If a "2.5%" account is clearing 3.2%+, you've found the junk fees or an unfavorable card mix.
- Kill the junk fees. Complete the PCI questionnaire, dispute the statement fee, ask what the "technology fee" buys. These die by phone call surprisingly often.
- Run the plan-tier math your vendor won't. Toast's own July figures: Pay-as-you-Go's 3.09% beats Traditional's 2.49% + $69/month only below $11,500/month in card sales — above that, the "free" plan is the expensive one. Same structure as Square's tiers, where Plus's lower rate overtakes Free above $49,000/month (worked in our POS cost guide).
- Know your lock-in before negotiating. Toast requires Toast payments; SpotOn's $0 All-In plan carries processing minimums and a 2-year minimum term. Where the processor is bundled, the negotiation happens before you sign — get competing POS quotes in writing and make them bid the rate, not the software.
- Get an interchange-plus quote at volume. Above ~$15–20k/month on cards, a pass-through quote is your benchmark; even if you stay flat-rate, it's leverage.
- If you surcharge, do it lawfully. Cap at your actual cost, mind the state list, disclose properly — or take the quieter 2% menu-price route.
Processing is the rare restaurant cost that responds to an afternoon of arithmetic with no operational change at all. The networks publish the caps, the honest vendors publish the rates, and the settlement will shave its tenth of a point on its own schedule — but nobody audits your statement for you. It's the same discipline as food cost: small percentages on big volume are where the money hides.
