Credit Card Processing Rates Compared: The 2026 Small-Business Guide

Card processing is the largest recurring bill most small businesses pay and the one they understand least. It does not have to stay that way. This is a plain-English 2026 comparison — what the pricing models are, what the majors actually charge, where the traps are, and how to compute your own effective rate in five minutes.

How processing pricing works

Every card fee is really three fees stacked: an interchange fee set by the card networks and paid to the issuing bank, a small network assessment paid to Visa/Mastercard/etc., and a processor markup that your provider keeps. What differs between providers is how they package those three.

• Flat-rate. One number covers everything — interchange, assessments, and markup. Simple math. Slightly higher on cheap cards, lower on expensive ones. Best for owners who value predictability and hate statements.
• Tiered. Providers bucket cards into Qualified, Mid-Qualified, and Non-Qualified. Rewards cards, keyed-in transactions, and international cards get pushed to the more expensive buckets — often silently. Best for the provider, rarely for you.
• Interchange-plus. You pay actual interchange + a fixed markup + a small monthly fee. Cheapest at high volume, hardest to shop for, and requires you to actually read the statement to catch errors.

Most independent shops under about $500k/year land better on flat-rate than on tiered. Interchange-plus starts to pay off higher up, but only if you have the time (or an accountant) to audit statements monthly.

The 2026 rate table

Verified from the current pricing pages and merchant agreements of each provider:

• Square — 2.6% + 15¢ in person on Free and Plus, 2.4% + 25¢ in person on Premium; 3.3% + 30¢ online on the Free tier.
• Shopify — 2.5–2.9% + 30¢ online depending on plan, plus a 0.6–2% penalty on transactions processed through a third-party gateway instead of Shopify Payments.
• Lightspeed — 2.6% + 10¢ on Lightspeed Payments, plus up to $400/month if you bring your own processor instead.
• Clover — 2.3–2.6% + 10¢ for card-present (reseller-set), 3.5% + 10¢ for card-not-present.
• SkyTab — 2.75% + 15¢ standard, inside a 36-month station agreement.
• Simple — 2.39% flat, in person and online, no third-party penalty.

Two things to notice. First, the in-person versus online split matters more than the base rate on any provider that has one — the online rate is often 40–90 basis points higher. Second, the "third-party penalty" clauses on Shopify and Lightspeed are a real fee, not a footnote. If you are on either platform and using an outside processor, price that line in.

Why in-person and online rates differ

Card-not-present transactions carry more fraud risk than card-present ones, so interchange itself is higher. Providers pass that through, and often add more markup on top because online shoppers are less price-sensitive to the fee they never see.

The practical implication: if 30%+ of your card volume is online, the online rate matters more to your P&L than the in-person one. Compare providers on the number that reflects your actual mix, not the one on their homepage.

Watch-outs

Reclassification. On tiered pricing, a card can be re-bucketed to a higher tier for reasons that are opaque from your side. A statement showing lots of Mid- and Non-Qualified fees on a normally routine card mix is a signal to audit — or switch to a model that cannot do it.

Per-transaction cents on small tickets. This one hurts more than owners realize. A 15¢ per-transaction fee on a $5 sale is effectively a 3% surcharge, on top of the percentage rate. On coffee, snacks, single-item retail, or any tip-only transaction, per-transaction cents can double your effective rate. Providers with a lower per-transaction fee — or none at all — save real money at small-ticket businesses.

Monthly minimums. Some merchant accounts charge a monthly minimum in processing fees. If your volume dips (seasonal shop, closed month), you pay the minimum anyway.

PCI compliance fees. Often $10–$30/month, sometimes bundled and sometimes not. Ask specifically.

Effective-rate worksheet

The only number worth comparing is your effective rate, which is total fees ÷ gross card volume. To compute it:

1. Pull your last three full months of merchant statements. 2. Sum gross card volume and total fees — every line, including monthly, PCI, batch, and per-transaction fees, not just the percentage. 3. Divide.

The result is a percentage that already includes every hidden charge. Compare it to any provider's advertised rate + per-transaction fee applied to your same volume and ticket mix. If a candidate provider's projected number is 20+ basis points lower on the same volume, that is real money. Under 20 basis points, the switching cost usually beats the savings — but re-check every 12 months.

Our pricing calculator runs the projected side automatically once you plug in a volume, and our merchant services page walks through what each line on a merchant statement actually means. For the frame around picking the whole stack — not just the rate — see our POS cost breakdown or the payment processing overview.

The one-line summary

Processing rates are three fees stacked in a package. The package that saves you money depends on your volume, your ticket size, and your online share — not on which provider is loudest. Compute your effective rate, project each candidate against your actual mix, watch the per-transaction cents on small tickets, and re-check annually. That is the whole discipline.
