How much does Square take from $100?

A customer taps their card at your counter, and $100 lands in your Square account — minus a fee you can predict to the penny. The exact amount depends entirely on how the payment happens, and the difference compounds with every sale.

According to Square's own fee calculator, an in-person card sale (tap, dip, or swipe) costs 2.6% + 15¢. On a $100 sale, that's $2.75, leaving $97.25 in your pocket. This is the number most business owners actually need, since in-person card payments dominate at counters, food trucks, and service calls.

Online sales cost noticeably more. Square charges 3.3% + 30¢ on its free plan and 2.9% + 30¢ on paid plans, so a $100 online transaction runs between $3.20 and $3.60. Manually keyed-in payments — typing a card number into the terminal — are the most expensive at 3.5% + 15¢, taking $3.65 from every $100.

These flat rates sit at or above the industry average — Visa and Mastercard charged merchants an average swipe fee of 2.35% in 2024, according to Nilson Report data. The burden is also growing: total card fees paid by U.S. merchants rose 70% since 2019, hitting a record $198 billion in 2025.

The cheapest ways to get paid through Square:

• ACH bank transfers: 1% with a $1 minimum and $10 cap — just $1.00 on a $100 invoice
• Bitcoin: 0% fee until 2027, per Square's calculator
• Square Premium plan: 2.4% + 15¢ in-person, cutting the fee to $2.55
• Custom pricing for high-volume merchants with $250K+ in annual card sales

The bigger picture is the pattern, not any single rate. Square's percentage model takes $2.55 to $3.65 from every $100 depending on payment method — a cost that scales with your revenue. A fixed monthly software fee, like the all-included model at AI Business Sites, stays the same whether you process $5,000 or $50,000 a month. For a business doing $50,000 a year in in-person card sales, Square's take alone reaches $1,375 annually — and it keeps climbing as you grow.

The cost of processing payments through Square can vary significantly depending on how you receive payments. For small businesses, understanding these variations is crucial for managing operational costs and optimizing profitability. Square's fees are structured to cater to different payment methods, with in-person transactions typically being the most cost-effective.

For instance, an in-person $100 card sale incurs a fee of roughly $2.75, leaving the merchant with approximately $97.25. This fee structure is largely due to the efficiency and security of in-person transactions, which generally have lower processing risks compared to online or manually keyed-in payments. Square's own fee calculator confirms that in-person rates can vary from 2.6% + 15¢ to 2.4% + 15¢, depending on the plan selected by the merchant. This means that for businesses prioritizing in-person sales, Square offers competitive rates that align closely with industry standards.

However, not all transactions are equal in terms of cost. Online payments, which are increasingly common in today's digital landscape, come with slightly higher fees. According to industry benchmarks, the average swipe fee charged by Visa and Mastercard in 2024 was 2.35%, a new high. This underscores the growing cost burden of swipe fees, which have risen 70% since 2019. For online transactions processed through Square, the fees can range from 3.3% + 30¢ on the free plan to 2.9% + 30¢ on paid plans. This discrepancy highlights the importance of choosing the right payment processing plan based on your business model.

Manually keyed-in transactions are the most expensive method, with fees as high as 3.5% + 15¢, or $3.65 on a $100 transaction. This method is often used for phone orders or when the card is not present, and it carries higher risks of fraud and chargebacks, which is reflected in the increased fees. Additionally, it's important to note that refunds through Square do not return the processing fees, adding another layer of cost for businesses.

• In-person transactions are the most cost-effective, with fees around $2.55–$2.75 on a $100 sale.
• Online payments incur higher fees, typically around $3.20–$3.60 on a $100 transaction.
• Manually keyed-in transactions are the most expensive, with fees up to $3.65 on a $100 sale.
• Refunds do not return processing fees, adding to the overall cost.

Most merchants never question Square's default rates — they swipe, pay the percentage, and move on. But the same platform offers several dramatically cheaper ways to get paid, and the savings are hiding in plain sight.

The biggest lever is ACH bank transfers. Instead of paying 2.6% + 15¢ on every card swipe, merchants can invoice customers and collect via ACH at a flat 1% with a $1 minimum and $10 cap, according to Square's own fee calculator.

On a $100 invoice, that's $1.00 to Square instead of $2.75 — and on larger invoices, the $10 cap makes ACH even more attractive. Bluevine's analysis confirms the 1% ACH rate for high-value invoices.

Bitcoin payments go even further: Square charges 0% on Bitcoin until 2027. A $100 sale paid in Bitcoin nets the full $100. It's not the right fit for every customer base, but for businesses with crypto-friendly clients, it's the cheapest transaction Square offers.

For card payments, the method matters as much as the rate. In-person tap, dip, or swipe transactions cost 2.6% + 15¢ — $2.75 on a $100 sale, per Square's published rates. Online payments run 3.3% + 30¢ on the free plan, or 2.9% + 30¢ on paid plans, according to 2026 payment processing data. Manually keyed entries are the most expensive at 3.5% + 15¢, or $3.65 per $100. Steering customers toward in-person or invoiced ACH payments is the single fastest way to cut processing costs.

High-volume merchants have another option entirely: negotiation. Businesses with annual card sales exceeding $250,000 and average transaction values above $15 can qualify for custom pricing, according to Bluevine. The published rates are starting points, not ceilings.

The actionable takeaways:

• Use ACH for invoices over $100 — the 1% flat fee with a $10 cap beats every card rate
• Accept Bitcoin where feasible — 0% until 2027
• Prioritize in-person payments over online and keyed-entry
• Ask about custom pricing if you clear $250K in annual card sales
• Avoid refund-heavy workflows — processing fees don't come back with refunds

None of these moves require leaving Square. They just require knowing the rate card. And for business owners weighing whether percentage-based processing is the right model at all, the contrast with a predictable flat monthly cost — like AI Business Sites' all-included $497/month platform — becomes easier to evaluate once you see exactly what each $100 costs you.

Here's a math problem most owners never run: a $100 sale costs $2.55 to $3.65 in Square fees depending on how the customer pays, and that percentage never stops — it takes a bigger bite every time revenue grows. A flat monthly cost behaves the opposite way, and the difference compounds fast.

Run the numbers on a single $100 sale first. An in-person card payment runs 2.6% plus 15¢ per Square's own fee calculator, leaving you $97.25. Online sales cost more — 3.3% plus 30¢ on the free plan, $96.40 per $100 — and manually keyed-in payments are the worst at 3.5% plus 15¢, or $3.65 per Bluevine's analysis.

Now multiply. A business processing $10,000 a month in card sales pays roughly $270–$360 in percentage-based fees, every month, at current rates. That's $3,240–$4,320 a year — and the bill scales with success. Double your sales and your processing cost doubles with it.

The broader trend makes this worse, not better. Merchants paid a record $198.25 billion in swipe fees in 2025, a 70% increase since 2019, according to Nilson Report data. For many retailers, these fees now rank second only to wages as a cost of doing business.

Contrast that with a fixed monthly cost. A flat fee — like the $497/month all-included model from AI Business Sites, which covers hosting, content, CRM, and the sales tools on your site — stays the same whether you do $5,000 or $50,000 in a month. As revenue grows, the fixed cost shrinks as a percentage of sales. The percentage model does the reverse: it claims the same slice forever, no matter how big the pie gets.

• Percentage fees scale with revenue — grow 50%, pay 50% more in processing
• Fixed monthly costs stay flat, becoming a smaller share of sales as you grow
• At $10,000/month in card volume, percentage fees run roughly $3,200–$4,300 a year
• Refunds don't return the processing fee, so the percentage cost sticks even on returned sales

To be fair, processing fees are a separate line item from software — you'll pay card processing under almost any setup, and Square's rates sit near the industry average of 2.35% for Visa and Mastercard swipe fees in 2024. The point isn't that processing is avoidable; it's that owners should tally it honestly as a variable cost that grows with every dollar of revenue.

The takeaway: when comparing platforms, don't just look at the sticker price. Add up what the percentage-based costs will actually take from you over a year of real volume, then compare that against a predictable flat fee. For a growing business, the math usually favors the model that doesn't take a bigger cut every time you have a better month.

Every percentage point you shave off payment costs goes straight back into your pocket. If Square takes $2.55–$3.65 from every $100 sale depending on how the payment arrives, the fastest raise you'll get this year is the one you give yourself by changing how money reaches you.

Start with an audit of what your customers actually pay with. Square's own calculator shows in-person card payments at 2.6% + 15¢ ($2.75 per $100), while online sales run 3.3% + 30¢ on the free plan ($3.60 per $100) and keyed-in manual entry hits 3.5% + 15¢ ($3.65 per $100), according to fee breakdowns. If you're taking payments over the phone or typing card numbers in, you're paying the most expensive rate for no good reason.

Then push large invoices toward ACH. Square charges a flat 1% on bank transfers — just $1.00 on a $100 invoice, with a $1 minimum and $10 cap — per Square's fee calculator. On a $5,000 invoice, that's the difference between $50 and $145. Make ACH the default option on every invoice you send and let card payments be the exception.

A few more habits worth building:

• Prioritize in-person payments wherever possible — they carry the lowest published rates
• Avoid manual card entry entirely; it's the costliest method at $3.65 per $100
• Remember that refunds don't return processing fees, so every refund costs you twice
• If you process over $250,000 annually with average tickets above $15, negotiate custom rates

The bigger move is owning your checkout. When payments run through your own website with your own Stripe account — the way we build it at AI Business Sites — money flows directly to you, and the platform never touches your funds. You keep the customer relationship, the payment data, and the revenue instead of renting all three from a processor.

It matters because the trend isn't in your favor. Merchants paid a record $198.25 billion in swipe fees in 2025, up 70% since 2019, according to Nilson Report data. Percentage-based processing is a cost that compounds as you grow; a predictable flat monthly cost doesn't. That's the structural difference between paying a cut of every sale forever and paying one price for the system that runs the business.
