Credit Card Processing Fees and What You Actually Pay

The two parts of every card fee

Card pricing has one shape. A percentage of the sale, plus a flat number of cents. Square's in person rate is 2.6% + 15¢, so a $40 sale costs you $1.19 and a $6 sale costs you 31¢.

Underneath that one quoted rate sit three separate charges. Only one of them can move.

• Interchange is the slice that goes to the bank which issued your customer's card. Visa and Mastercard publish the rates and set them. No processor can discount it.
• Assessments go to the card network itself. Also fixed.
• The processor markup is what your provider keeps for doing the work. This is the only piece anyone can negotiate.

That distinction matters the moment a sales rep offers to beat your current rate. He can cut his own margin. He cannot cut interchange, so a promise to lower it is a promise about something outside his control.

What the regulator caps and what it leaves alone

Debit is different. The price there is capped by law. Under the Federal Reserve's Regulation II, a covered bank may not take more than 21¢ plus 0.05% of the sale in debit interchange, plus a penny for fraud prevention where it qualifies. On a $60 debit sale that comes to about 24¢.

You still pay your processor's full 2.6% + 15¢ on that sale, which is $1.71. The other $1.47 covers network assessments and your provider's margin. This is not a trick. Flat rate pricing means one blended price on every card, so a cheap debit sale helps fund an expensive rewards card sale, and you never meet a surprise on the statement.

Where you can start with no monthly fee

Square's entry plan costs nothing a month. You pay 2.6% + 15¢ when a card is tapped, dipped or swiped, 3.3% + 30¢ on an online order or an invoice, and 3.5% + 15¢ if you type the number in by hand. There is no subscription and no minimum.

Start there if you are new. For a business that has not yet learned its own volume, that is the sane place to begin. You are not paying a monthly bill to find out what your monthly bill should be.

Be clear on what free means here. It buys you no software fee. It does not buy you cheap processing, and at a small average sale the 15¢ does more damage than a subscription ever would. The next two sections show exactly where that flips.

What our five point of sale partners charge

A point of sale system is the software and hardware that rings up a sale, and most of them process the card as well. We carry five. Every rate below was read at the provider's own pricing page on 29 August 2026.

Three of the five print a number. Two do not. Toast lists software from $69 a month and describes flat rate processing without ever showing the rate, and Lightspeed routes you to its sales team. Quoted pricing is normal in this trade and neither is hiding anything unusual. It does mean you cannot compare them on price until you have spoken to someone.

Notice what the published three have in common. All three charge 2.6% in person. The percentage is not where they compete. Square asks 15¢ a sale where the other two ask 10¢, and Square is the one with no monthly fee, which is the whole trade being offered.

Climbing the Shopify ladder

Shopify POS keeps the cents at 10¢ on every plan and buys down the percentage instead. Basic is $39 a month at 2.6%. Grow is $105 at 2.5%. Advanced is $399 at 2.4%. A retail location that wants staff permissions and inventory tools adds POS Pro at $89 a month per location.

If most of your sales happen on a website rather than a counter, the platform decides the rate as much as the processor does, and our ecommerce platform guide compares that side.

The line items that never appear in the quote

Square, Shopify POS and Clover sell flat rate pricing. One price per sale, no monthly minimum, and the statement matches the quote. A traditional merchant account works differently. That is an account opened for you at a bank through a processor, and its statement carries charges the headline rate never mentions.

These are the ones to look for by name.

• PCI compliance fee, billed monthly or yearly for card security certification.
• Monthly minimum, a floor you pay even in a quiet month.
• Statement fee, charged for producing the statement itself.
• Batch fee, charged each time you settle the day's takings.
• Non qualified surcharge, applied when a card falls outside the tier you were quoted.

The last one does the real damage. Under tiered pricing a rewards card, a corporate card or a keyed sale gets bumped into a dearer band, so the rate you were sold ends up applying to a minority of your sales. This is the commonest reason a merchant runs his own numbers and finds a rate he does not recognise.

Flat rate providers dodge this by design. Square charges one price, 2.6% + 15¢ in person, whatever card the customer presents.

Merchant accounts are not the villain here. Above a certain volume they beat flat rate comfortably. Read the statement, not the sales sheet.

Find your real rate before you shop

One number settles this. Your effective rate is what you actually paid, everything counted. Take every processing charge on last month's statement, divide it by your total card sales, and multiply by 100.

Say you paid $312 on $9,400 of card sales. Your effective rate is 3.32%. That one figure is the only fair way to weigh two offers, because it swallows the percentage, the cents, the monthly fee and every line item at once.

Then hold it up against your average ticket. A good effective rate is not one number for everybody.

The advice repeated all over the web is that a good effective rate sits between 2% and 3%. Read the table again. A coffee shop at a $6 average ticket cannot reach 3% on any flat rate plan sold today, however well it negotiates. That benchmark was written for a business with a bigger basket, and pointed at a small one it just tells a good operator he is failing.

So the saving is rarely in the percentage. Three moves actually work. Get the cents down if your basket is small, because that column is where your money goes. Take the card in person where you can, since keyed and online rates run a point dearer. And once you are past roughly $25,000 a month, ask a merchant account provider to quote interchange plus a named markup, then compare it against the effective rate you just worked out.

One last place the money leaks. Processing charges land on the account you deposit into, and a bank that charges you again on the way in undoes part of the saving. We break those down in our guide to business bank account fees, and if you have not opened one yet, start with how to open a business bank account.

When a monthly fee starts paying for itself

Compare these two. Square's free plan charges 2.6% + 15¢ and nothing a month. Shopify POS Basic charges 2.6% + 10¢ and $39 a month. The percentages are identical, so the whole decision comes down to a nickel against thirty nine dollars.

The crossover is 780 sales a month. Below that Square is cheaper, above it Shopify is. What the crossover means in revenue depends entirely on the size of your basket.

The grid holds the argument. A coffee shop crosses over on modest takings, while a furniture shop selling $120 pieces has to clear $93,600 a month before the same plan earns its keep. Two businesses, one decision, opposite answers, and the only thing that changed was the average ticket.

Higher up, volume takes over. Shopify's Grow plan trades $105 a month for a 2.5% rate, which beats Basic once you pass $66,000 in monthly card sales. Advanced trades $399 for 2.4%, which beats Grow above $294,000. Both crossovers hold at any ticket size, because the 10¢ never changes across the three plans.

One caution before you move. These figures compare processing cost alone. A plan can be worth paying for on features you need, inventory tools or staff permissions or a second location, long before the arithmetic says so, and the crossover tells you what that convenience costs rather than whether to buy it.
