Stripe vs Square Fees Compared: Which One Costs

Stripe vs Square: Same Job, Different Strengths

Stripe and Square are the two payment processors most small businesses compare first. Stripe is the developer-friendly online payments platform that powers checkout for millions of websites and SaaS products. Square started with the little white card reader for in-person sales and has grown into a full point-of-sale and business ecosystem.

The good news is that their headline online rates are nearly identical, so the decision usually comes down to how you take payments, not the sticker rate. This comparison breaks down every fee category that actually affects your bottom line.

Fee Structures Side by Side

Both processors publish standard US rates that follow the same pattern: a percentage of each transaction plus a small fixed fee. Here is how the categories generally compare:

Payment Type	Stripe (typical US rate)	Square (typical US rate)
Online card payments	Around 2.9% + 30c per transaction	Around 2.9% + 30c per transaction
In-person (chip/tap)	Around 2.7% + 5c via Terminal	Around 2.6% + 10c or 15c depending on plan
Invoices	Standard online rate applies	Around 3.3% + 30c for card-paid invoices
ACH / bank transfers	Low flat percentage, capped per transaction	Around 1% with a minimum fee
Monthly fee	None for standard accounts	None for standard accounts

Rates change over time and vary by country, so treat these as the long-standing standard structure and confirm current published rates before deciding. Neither charges a monthly fee for its basic account, which is why both are popular with new businesses.

Worked Example: $10,000 in Monthly Sales

Imagine a business processing $10,000 per month across 200 transactions (a $50 average order). Online, both Stripe and Square at roughly 2.9% + 30c would cost about $290 in percentage fees plus $60 in fixed fees, for a total around $350, or 3.5% of revenue. The fixed 30 cents stings more on small tickets: on a $10 sale it adds 3% all by itself.

In person, the math tilts slightly toward Square for small tickets: 2.6% + 10c on a $50 sale costs $1.40 versus Stripe Terminal's 2.7% + 5c at $1.40, effectively a tie at that ticket size, with Square edging ahead on smaller sales and Stripe on larger ones. The takeaway: for most businesses the difference is tens of dollars a month, not hundreds, so pick based on tools rather than fractions of a percent.

Beyond the Rate: What Really Separates Them

• Online and SaaS billing: Stripe wins clearly. Its APIs, subscription billing, and developer tooling are the industry standard for websites, apps, and recurring revenue businesses.
• In-person retail and restaurants: Square wins clearly. Its free POS app, hardware ecosystem, and built-in inventory, staff, and loyalty tools are purpose-built for physical locations.
• Invoicing: Both offer it, but Square's invoicing is more beginner-friendly while Stripe's fits businesses that want automation and API control.
• Payout speed: Both typically pay out in one to two business days on standard schedules, with instant payout options available for an additional fee.
• International and extras: Stripe supports more currencies and countries out of the box. Square bundles more free business software (appointments, marketing) into its ecosystem.

Edge Cases: Chargebacks, Refunds, and International Cards

Headline rates cover the happy path. Real businesses also pay for the unhappy path. Chargebacks typically cost a flat dispute fee in the mid-teens per case on both platforms, win or lose, which makes fraud prevention worth more than a tenth of a percent on your processing rate. If you sell in a high-dispute category like digital goods or travel, compare each processor's dispute tooling and evidence flows before you compare rates.

Refunds deserve attention too: policies on whether the original processing fee is returned when you refund a customer have changed over time on both platforms, so check the current terms rather than assuming. International cards and currency conversion add surcharges, often around an extra percentage point, which matters a great deal if a meaningful share of your customers pays from abroad.

None of these edge cases usually flips the Stripe-versus-Square decision on its own, but together they can add a few tenths of a percent to your effective rate. Estimate them honestly, add them to the worked example above, and choose based on the all-in number rather than the advertised one. The cheapest processor is the one that costs least on your actual transaction mix, not on a pricing page.

The Verdict: Which One Costs Less for You?

If you sell mostly online or run a subscription business, Stripe's tooling makes it the better value even though the headline rates match Square's. If you sell mostly in person, Square's slightly better in-person rates and free POS software make it the cheaper and simpler choice. Many businesses end up using both: Stripe for the website, Square for the register.
