Stripe Terminal vs Square POS 2026: Fees for Retail Stores

For a US shop taking 500 in-person card payments of $40 each, Stripe Terminal's published standard rate produces $565 in processing fees, versus $595 on Square Free, before equipment, tax, add-ons and integration costs. Stripe lists 2.7% plus 5 cents per successful card transaction, and Square Free lists 2.6% plus 15 cents for in-person tap, dip or swipe, with both prices checked October 28, 2026.

Square is the better starting point when you need a ready-made POS, since Terminal is readers and integrations rather than a staffed checkout. The $30 gap leaves out software you must build or buy, so wait for that quote before you treat the processing difference as the whole cost.

Stripe Terminal vs Square at a glance

Question	Stripe Terminal	Square Free POS
US in-person card rate	2.7% + 5¢ per successful transaction	2.6% + 15¢ per tap, dip or swipe
500 payments of $40	$565 processing	$595 processing
Entry reader shown by vendor	Stripe Reader M2: $59	Square Reader: $59
Checkout software	APIs, SDKs or a supported third-party integration	Free POS software with inventory and sales reports
Main question to check	Integration cost and fit	Whether Free has the inventory and team features you need

Those rates come from Stripe's Terminal page and Square's US POS pricing. Square Free already includes a POS, while Terminal's rate assumes you bring or buy the checkout, so put the integration quote next to either column before you call it the bill.

How much do they cost for a small shop?

Stripe's processing bill is lower on this basket because the fixed fee is smaller, not the percentage. Model one US store on the payment count in the tables, counting only successful domestic cards taken on a physical reader rather than phone-based Tap to Pay.

At $40 per transaction, sales are $20,000, and Stripe's percentage fee is $540 with fixed fees of $25, for $565. Square's percentage fee is $520 and its fixed fees add $75, for $595, a $30 monthly saving for a low-ticket shop that already has checkout software.

Monthly card payments	Sales	Stripe Terminal processing	Square Free processing	Difference
500 × $40	$20,000	$565	$595	Stripe $30 lower
same volume × $100	$50,000	$1,375	$1,375	Equal
same volume × $120	$60,000	$1,645	$1,635	Square $10 lower

The lower rows keep that payment count and change only the ticket, so the winner can flip without any extra cards. They use the listed standard rates and omit refunds, disputes, taxes, hardware, third-party POS charges and international surcharges, so returns or foreign cards make the gap a floor rather than the invoice.

Why the average sale changes the answer

Stripe's percentage component is 0.1 percentage point higher, but its fixed component is 10 cents lower, which is why the winner flips as the ticket grows. At a $100 sale, the extra percentage is 10 cents and exactly offsets that fixed-fee gap, so neither listed rate wins on processing.

Below that ticket, Stripe's physical-reader rate costs less per sale, which suits a counter of small baskets. Above it, Square Free costs less per sale, so a higher-ticket shop should not pick Terminal to save on the rate. Where the listed fees match, the remaining decision is the software quote, not the card math.

This break-even covers only those two processing rates, so a paid integration, a device or a mixed batch of cards can still outweigh a few cents per sale.

What does Square include for free?

Square Free is how a single counter opens without a software subscription, and the paid plans buy features until volume covers them. The US comparison describes a Free plan at $0 per month with item management, inventory and sales reports. Its pricing page lists Plus at $49 per month per location and Premium at $149 per month per location. Confirm the product on your account, because those tiers change the rate and the features together.

Square's published Plus rate is 2.5% plus 15 cents per in-person transaction. Set against the Free rate in the table, the percentage difference is 0.1 percentage point and the fixed fee does not change. On processing alone, that $49 subscription needs $49,000 in monthly eligible card sales before the saving equals the plan. Below that volume you are paying for features, and staff permissions or multi-location inventory are the reasons to pay sooner.

Compare Square's per-location subscription as well as its card rate; the Stripe figure is only processing. Terminal's software and integration still have to be priced, so a cheaper card line can lose once both quotes sit on one sheet. The wider Square product is in our Square POS review.

What does Stripe Terminal include?

The published Terminal cost is the reader, and the checkout around it is the part a shop tends to leave out. Stripe describes it as readers, development kits and integrations, and Terminal pricing lists a $59 M2 reader and $299 S700 and S710 devices plus the standard card fee. Those prices omit inventory, staff tools and the work to connect them, so get that quote before the card rate means anything.

A retailer already on a supported platform can often add Terminal through that integration, which is when this stops being a build. A custom app means reading the Terminal documentation with a developer and pricing the work. Count a quote as software plus processing only when the quote says so.

If you already take payments online, one workflow for the site and the counter can be worth that build, because split processors leave a reconciliation job at every close. Wider options are in our best POS systems and POS for small retail stores guides.

Hardware and fees that can change the bill

A reader is a one-time purchase, not a monthly percentage, so leave it out of the per-card comparison. The entry readers in the table share a list price and are still different devices, so check connectivity and accessories, and skip one that cannot serve your floor.

Stripe lists an additional 10 cents per authorization for phone-based Tap to Pay and 5 cents per authorization for optional point-to-point encryption, and neither fee is in the worked table. A phone-only counter pays the Tap to Pay charge on each authorization, which can differ from completed sales, so add it before you trust the gap.

The same page adds 1.5% on international cards and $10 per reader per month for cellular on enabled readers, neither of which is in the worked rows. Foreign cards can outweigh the processing difference, and a store that needs cellular should add that monthly line before comparing the rates.

Disputes sit outside the table and can exceed the monthly processing gap. Stripe's US pricing page lists $15 when a dispute is received and another $15 if you counter it manually, refunded when you win, and rare network charges can apply as well.

Square's tap rate is the wrong input for other ways of paying. Its POS page shows 3.5% plus 15 cents for manually entered or saved-card payments, a heavier schedule than tap, dip or swipe. A shop that keys phone orders and still uses the in-person rate will understate what it pays.

Which is better for retail inventory?

If you need items, inventory and reports in order to open, check Square Free against variants, receiving, locations and staff permissions before you price a reader. Price Plus when permissions are the blocker, rather than assuming Terminal plus another app is the only way up.

Score Terminal with the app attached to it, because returns, stock updates, offline sales and support live in that software. Skip it when those answers are still a promise rather than a product you can staff. If the counter also sells online, compare Square vs Shopify POS and Lightspeed vs Shopify POS before the reader is locked to one processor, then use the POS for clothing boutiques and POS for coffee shops guides when ticket size is the real question.

Questions to ask before you switch

Pull a month of your own tickets and count successful in-person transactions as well as card volume, because the fixed fee punishes a high count even when the sales totals match. The fixed-fee portion depends on how many payments make up the total sales, while the percentage applies to the transaction amounts.

Then price each reader, the software, onboarding and support, and ask whether a third-party POS bills Terminal apart from the standard rate shown here. Map refunds before you move, because a charge can clear while the order still needs a manual fix, and price web or keyed sales apart from the counter using the ecommerce platform reviews and the inventory software guide.

Frequently asked questions

Is Stripe Terminal a complete POS?

Stripe offers payment readers, developer tools and supported integrations, so the hardware alone is not a checkout your staff can run. A complete POS comes only from software you build or connect, which fits a retailer that already has the app and is a weak first step for a shop that still needs a catalog.

Is Square POS free?

Square lists a Free POS plan at $0 per month for the software, not for the cards or the reader. Processing and hardware still cost money, and paid plans add features with a charge per location, which is where another site or a larger staff stops being free.

Which has lower in-person processing fees?

At the two standard US rates used here, Stripe costs less on a ticket under $100 and Square Free costs less above that ticket, with the listed fees equal at that same ticket. Software, equipment and other fees sit outside this answer, so ignore the rate winner until you know the cost of any POS you still have to buy.

How much is a card reader?

The vendors list the Stripe Reader M2 and the Square Reader at $59 each, a one-time hardware cost rather than a monthly fee. They are different devices, so confirm compatibility and the checkout price, and skip the reader that cannot run the connection your counter needs.

Does Stripe charge extra for phone Tap to Pay?

Stripe's Terminal pricing lists 10 cents per authorization for Tap to Pay on top of the processing rate, including authorizations that never become a sale. The worked table assumes a physical reader and leaves that charge out, so a phone-only counter should add it before trusting the gap.

Can Square's paid plan reduce the card rate?

Square lists a lower in-person rate on Plus at $49 per month per location, so the rate cut is not free. At the published rates, $49,000 in monthly eligible card volume is the processing-only break-even against Free.

Do these figures include international cards?

No, the worked figures leave international cards out, and Stripe lists a 1.5% surcharge on top of the domestic rate. Check the Square terms for your account and the foreign cards you actually take, because that surcharge can swallow the processing difference.

Should a small store buy based on processing rate alone?

No. Price the software, the hardware, the locations and the inventory work you will actually do, because those lines can dwarf the card gap in the example. The lowest transaction fee is the wrong target when one option still needs a POS you have not paid for.
