Square's credit card fees explained
Square charges a flat rate of 2.6% plus 10 cents per transaction for in-person card payments, and 3.5% plus 15 cents for online or phone payments. These are the standard rates for most small businesses using Square's basic payment processing. If you use Square's point-of-sale system, you pay the same per-transaction rate; if you use their online checkout, the rate is higher. There are no monthly fees, no setup fees, and no cancellation fees — you pay only when you process a card payment.
The rate structure matters because it means your total cost depends on your average transaction size and sales volume. A $10 sale costs you about 36 cents; a $100 sale costs about $3.70. Square does not charge different rates based on whether the card is debit or credit, or whether it's a rewards card. The fee is the same regardless.
Key Takeaways
- Square charges 2.6% plus 10 cents for in-person payments and 3.5% plus 15 cents for online or phone payments, with no monthly or setup fees.
- You pay only when a card is actually processed; declined cards and cash payments incur no fee.
- Square's rates are fixed and do not change based on card type, customer volume, or how long you have been with them.
- Additional fees explore if you use Square's invoicing tool, request a same-day payout, or process payments through certain integrations.
When you pay Square's standard rate
The 2.6% plus 10 cents rate applies to in-person transactions — card present at the register or using Square's mobile reader. This is the lowest rate Square offers because the card is physically verified. The 3.5% plus 15 cents rate applies to card-not-present transactions: online checkout, phone orders, or invoices paid by card. The higher rate reflects the greater fraud risk when the card is not physically present.
You are charged only when the transaction completes. A declined card, a voided sale, or a refund does not trigger a fee. Cash payments have no fee. If a customer disputes a charge later and the dispute is resolved in their favor, Square refunds the processing fee along with the transaction amount.
Additional fees beyond the per-transaction rate
Square's invoicing tool charges 2.9% plus 30 cents when a customer pays an invoice by card. This is higher than the standard in-person rate because it is a card-not-present transaction. If you send an invoice through Square and the customer pays by ACH bank transfer instead, there is no fee.
Same-day payouts cost 1% of the transfer amount, with a $10 minimum. Standard payouts arrive in one to two business days and have no fee. Chargebacks and disputes cost $15 each if they are ruled against you. International card processing (accepting cards issued outside the United States) costs 3.9% plus 30 cents.
If you use Square's point-of-sale system with hardware like a register or receipt printer, there is no monthly fee for the software, but you pay for the hardware upfront — a Square Stand costs around $300 to $400, depending on the model.
How Square's rates compare to other processors
Square's 2.6% plus 10 cents in-person rate is in the middle range for small business payment processors. Stripe charges 2.7% plus 5 cents for in-person and 2.9% plus 30 cents for online. PayPal Here charges 2.7% plus 5 cents for in-person. Toast charges 2.89% plus 9 cents. The differences are small — a few cents per transaction — but they add up over time if you process high volume.
The real difference between processors is not the rate but what you get for it. Square includes free invoicing, free point-of-sale software, and free customer data tools. Stripe requires you to build your own checkout or pay for a third-party tool. PayPal Here is simpler but offers fewer features. If you need only basic card processing and do not need invoicing or customer management, a processor with a lower rate might save you money. If you need the full toolkit, Square's rate is competitive.
What Square does not charge for
Square does not charge monthly fees, annual fees, setup fees, or cancellation fees. You do not pay to open an account, and you do not pay to close one. There is no minimum monthly processing volume. You can process one transaction a month or ten thousand and pay the same per-transaction rate.
Square does not charge fees for failed transactions, voided sales, or refunds. You do not pay to add team members, create customer profiles, or send invoices (though customers who pay those invoices by card trigger the 2.9% plus 30 cents fee). You do not pay for customer support — Square offers phone, email, and chat support at no cost.
How to lower your Square processing costs
The most direct way to lower costs is to encourage customers to pay by ACH bank transfer or check instead of card. ACH transfers through Square cost 1% with a $0 minimum, which is lower than card processing. Invoices paid by ACH have no fee. However, most customers prefer card payments, so this option works only if you have a reason to offer alternatives — for example, if you are invoicing a business customer who can pay by bank transfer.
If you process high volume, contact Square's sales team to ask about custom rates. Square does not publicly advertise volume discounts, but they do negotiate with businesses processing tens of thousands of dollars per month. You will not know if a discount is available unless you ask.
Batch your payouts instead of requesting same-day transfers. Same-day costs 1% and has a $10 minimum; standard payouts are free. If you can wait one to two business days, you save the 1% fee. Over a year, this can add up to hundreds of dollars depending on your volume.
Frequently Asked Questions
Does Square charge different rates for debit cards versus credit cards?
No. Square charges the same 2.6% plus 10 cents rate for all in-person card payments, regardless of whether the card is debit or credit. The rate does not change based on card type, issuer, or whether the card has rewards.
What happens if a customer disputes a charge?
Square charges $15 if the dispute is ruled against you. If the dispute is ruled in your favor, you keep the transaction amount and the processing fee. The customer can dispute a charge up to 120 days after the transaction.
Do I pay Square's fees if a customer's card is declined?
No. You are charged only when a transaction completes successfully. Declined cards, expired cards, and insufficient funds do not trigger a fee.
Can I negotiate Square's rates?
Square's published rates are fixed for most small businesses. However, if you process very high volume — typically $50,000 or more per month — you can contact Square's sales team to discuss custom pricing. There is no harm in asking, but rates are not negotiable for typical small business volumes.
What is the difference between Square's in-person and online rates?
In-person transactions (card present) cost 2.6% plus 10 cents because the card is physically verified. Online and phone transactions (card not present) cost 3.5% plus 15 cents because the fraud risk is higher. Invoices paid by card cost 2.9% plus 30 cents, which is between the two.
