Credit Card Payments for Small Businesses (2026 Real-Cost Guide)

A small US business pays roughly 2.3% to 3.5% plus a per-transaction fee to accept cards in 2026, depending on the processor and whether the sale is in person or online. On list prices checked October 14, 2026, Square charges 2.6% + 15¢ in person and 3.3% + 30¢ online, PayPal 2.29% + 9¢ in person (PayPal Point of Sale) and 2.99% + 49¢ online, and Helcim a markup of 0.40% + 8¢ over interchange.

Updated October 14, 2026: every processor fee below was re-checked on the vendor's own pricing page, the cost scenarios are new, and statistics we could not confirm at the source were removed.

Dupple data: Toolradar, which Dupple runs, tracks 186 payment processing tools and only 5 of them offer a free plan (toolradar.com payment processing category, October 2026). Accepting cards is almost never free, so the real question is which pricing model fits your volume.

What do the main processors charge in 2026?

Rates below are the standard US list prices each vendor publishes, checked on October 14, 2026. Your own rate can differ after underwriting, a negotiated quote or a volume tier.

Sources: Square pricing, PayPal business fees, Helcim pricing, Stripe pricing. Keyed-in cards cost more: Square lists 3.5% + 15¢ and PayPal Point of Sale 3.49% + 9¢.

The table has three gaps worth knowing. Stripe's standard US card rate sits on its pricing page, so read it there before you compare, and Stripe states it charges no setup or monthly fees. Clover is left out because we could not confirm a US list price on its own pages. Helcim's rate is a markup, not an all-in price, which the next section handles.

How much will accepting cards cost at $10,000 and $50,000 a month?

Fees are a percentage plus a fixed amount per sale, so your average ticket matters as much as your volume. These scenarios assume a $50 in-person ticket and a $100 online ticket, which means 200 and 1,000 in-person sales or 100 and 500 online sales. The arithmetic once: Square Free in person at that volume is 2.6% of $10,000, which is $260, plus 200 sales at $0.15, which is $30, so $290 a month.

The cheapest flat-rate option in person is PayPal Point of Sale, but only if PayPal approves you for it. It saves $43 a month at the lower volume against Square Free and $215 a month at $50,000. PayPal says Point of Sale is subject to eligibility, application and approval, so check that before you plan around it.

Square Plus only pays off above about $49,000 a month. Its 0.1 point in-person discount saves $10 per $10,000, so the $49 monthly fee breaks even near $49,000 of in-person volume. At $50,000 the two Square plans cost the same within $1. Online, the Plus rate (2.9% instead of 3.3%) saves $40 per $10,000, so it wins from roughly $12,000 a month.

Helcim is cheaper whenever your blended interchange stays low enough. Helcim passes interchange through at cost. Against Square Free in person at $10,000, Helcim wins as long as interchange is under $234 on that volume ($290 minus $56), which is 2.34%. Online against PayPal it wins under 2.73% ($348 minus $75). Your processing statement shows your real interchange. Helcim also says interchange rates typically move twice a year, usually in April and October, and its markup falls as volume rises (0.35% + 7¢ in person from $50K to $100K a month).

Flat-rate or interchange-plus: which pricing model fits?

Flat-rate pricing (Square, PayPal) charges one rate for every card, so you can forecast cost from a single number. The price of that simplicity is a premium on cheap cards, such as basic debit and non-rewards credit, which carry lower interchange. For a small-volume business, the premium is a few dollars and the predictability is worth it.

Interchange-plus pricing (Helcim) separates the card network's cost from the processor's markup. You see both on the statement, and the gap versus flat rate widens as volume grows. The weakness is comparison: you cannot read a single rate from a pricing page, because the total depends on your card mix. Helcim also says its volume discounts apply based on your average volume over the last three months, so a slow quarter can lift your markup.

Each option has a real downside. Square Free charges the highest online rate here (3.3% + 30¢), so an online-heavy seller should price the Plus plan. PayPal's online fixed fee of 49¢ hurts on small tickets: on a $10 sale it adds 4.9 points to the 2.99%. Helcim needs you to read statements. Stripe is built for developers, which suits online-first sellers but leaves a shop owner with more setup.

Those same processed dollars resurface at tax time on the 1099-K your processor files, and if you also pay contractors, high-volume senders rely on bulk 1099 filing software to issue year-end forms without hand-keying each one.

How do I choose a processor?

Match the model to your volume and where you sell.

• Under $10,000 a month, mostly in person: Square Free or PayPal Point of Sale (if approved). Zero monthly fee and a single rate.
• Online-first: compare Stripe's published rate with Square Plus (2.9% + 30¢) and PayPal (2.99% + 49¢) on your average ticket. A high fixed fee punishes small orders.
• $10,000 to $50,000 a month: run the break-even above. If your statement shows low blended interchange, Helcim's markup beats flat rates.
• Above $50,000 a month: ask Helcim and any other interchange-plus processor for a quote, since markup tiers fall as monthly volume rises.

The common mistake is comparing headline rates. A 1.5% rate with monthly minimums, statement fees and PCI fees can cost more than 2.6% flat. Helcim lists no monthly, minimum, software or statement fees, which is the benchmark to hold others against. Ask any processor for its full fee schedule before you sign.

Do I have to be PCI compliant if my volume is small?

Yes. Any business that accepts cards must follow the PCI Data Security Standard, and your processor will ask you to complete a self-assessment questionnaire. Using a hosted checkout from Square, PayPal, Helcim or Stripe keeps card numbers off your own servers and shortens that form. Ask your processor whether it bills a fee when the form is not filed.

FAQ

What is the average credit card processing fee for a small business in 2026?

Published flat rates for the main US processors run from 2.29% + 9¢ to 3.49% + 49¢ per sale in October 2026. Square Free is 2.6% + 15¢ in person and 3.3% + 30¢ online. Interchange-plus processors such as Helcim add a markup of 0.40% + 8¢ to interchange.

What is the cheapest way to accept credit cards?

For in-person sales at low volume, PayPal Point of Sale at 2.29% + 9¢ has the lowest flat rate in this comparison, subject to PayPal's approval. As volume grows, interchange-plus pricing such as Helcim (0.40% + 8¢ markup up to $50K a month) usually costs less when your interchange is low.

Is Stripe or Square cheaper?

It depends on where you sell and your ticket size. Square Free charges 3.3% + 30¢ online and 2.6% + 15¢ in person, and Stripe's standard US rate is on its pricing page. Compare both on your own average ticket, since the fixed fee changes the answer on small orders.

Is Square Plus worth $49 a month?

Only at higher volume. In person it saves 0.1 point (about $10 per $10,000), so it breaks even near $49,000 a month. Online it saves 0.4 point, so it wins from about $12,000 a month.

Can I pass card fees on to customers?

Helcim publishes a surcharging and convenience fee feature, but card network rules and state law limit when you can add a fee, so confirm the rules for your state and card types with your processor before turning it on.

Do I need PCI compliance?

Yes, at any volume. Your processor will send a self-assessment questionnaire, and a hosted checkout makes it shorter.

What is the difference between flat-rate and interchange-plus pricing?

Flat rate is one percentage for every card. Interchange-plus passes the card network's cost through and adds a fixed markup, as Helcim does with 0.40% + 8¢ in person up to $50K a month. Flat rate is simpler to forecast, and interchange-plus is usually cheaper once volume grows.
