Credit Card Processing Fees: Interchange and Average Rates

Quick answer: Credit card processing fees for small businesses typically run about 2.5% to 3.5% per transaction as of 2026, plus a fixed fee of up to 30 cents. Each fee combines three parts: interchange paid to the card-issuing bank, a network assessment for Visa or Mastercard, and the processor's markup. Interchange is the biggest piece, and it varies by card type.

If you send invoices and accept cards, these fees come straight out of your revenue. This guide breaks down how credit card processing fees are built, what interchange actually costs according to the card networks' own schedules, average rates by provider, and how to lower your effective rate. If you just need a professional invoice with a clear payment section, our free invoice generator lets you list card, ACH and bank details in a few minutes.

We cover individual providers in detail elsewhere, so this page stays focused on the big picture. For provider breakdowns, see Stripe fees, PayPal fees and Square invoice fees.

What Makes Up Credit Card Processing Fees

Every card payment passes through several parties, and each takes a slice. Understanding the slices is the first step to paying less.

• Interchange: paid by your processor's bank (the acquirer) to the customer's bank (the issuer). Card networks publish the rates, and they depend on card type, how the card was accepted, the merchant category and sometimes the transaction size.
• Network assessments: smaller fees Visa, Mastercard, Discover and American Express charge for using their networks. These are usually a fraction of a percent.
• Processor markup: what your payment processor or merchant services provider keeps for running the service, handling risk, providing software and paying out funds.

Visa states this plainly in its published schedule: merchants do not pay interchange themselves; they pay a "merchant discount" to their financial institution, which bundles interchange with everything else. Whether you see those parts separately depends on your pricing model, which we cover below. For the structural difference between a dedicated merchant account and an all-in-one processor, read merchant account vs payment processor.

Other fees that raise your real cost

Per-transaction charges are only part of the bill. Watch for monthly account fees, PCI compliance fees, statement fees, chargeback fees, instant payout fees and early termination fees on long contracts. A provider with a slightly lower percentage can cost more overall once these are added.

Interchange Rates in 2026: What the Networks Publish

Visa publishes its US interchange reimbursement fees in a public document. The edition with rates effective October 24, 2026 shows how widely interchange varies. The table below pulls a few representative lines; all are interchange only, before network and processor fees.

Visa transaction type (US)	Interchange as of Oct 2026
Regulated debit (large issuers), any channel	0.05% + $0.21
Exempt debit, CPS/Retail (card present)	0.80% + $0.15
Exempt debit, CPS/Card Not Present	1.65% + $0.15
Consumer credit, most qualified programs	roughly 1.2% to 2.7% plus 5 to 10 cents
Commercial card, card not present	2.70% + $0.10
Non-qualified consumer credit	3.15% + $0.10

You can check the full schedule in Visa's USA interchange reimbursement fees. Mastercard publishes a comparable US schedule with its own program names. The pattern is the same across networks: debit is cheapest, premium rewards and commercial cards are most expensive, and transactions that fail to qualify for a lower program fall into a costly non-qualified rate.

Why card-not-present costs more

When a customer pays an invoice online, the card is not physically present, so fraud risk is higher and interchange rises. The same exempt debit card that costs 0.80% + $0.15 at a till costs 1.65% + $0.15 online in Visa's schedule. That is why invoice payments almost always carry a higher rate than in-person taps.

Average Credit Card Processing Rates by Provider

Most small businesses use flat-rate processors, which hide interchange inside one blended price. Here are published US rates for invoice or online card payments as of 2026.

Provider	Invoice or online card rate	Bank (ACH) alternative
Stripe	2.9% + 30¢ (plus 0.4% for Stripe Invoicing Starter)	0.8%, capped at $5
Square (Free plan)	3.3% + 30¢ on invoices	1%, $1 minimum
PayPal	2.99% + $0.49 standard card; 3.49% + $0.49 PayPal Checkout	1%, capped at $10
QuickBooks Payments	2.99% on invoices	1%
Cash App for Business	2.75% per payment received	Not offered

Rates change, and each provider adds conditions for international cards, currency conversion and instant payouts. Our deeper guides cover QuickBooks Payments fees and Cash App business fees, and our Stripe vs Square comparison covers the two most common choices side by side.

Pricing Models: Flat Rate, Interchange-Plus and Tiered

How a provider prices its service matters as much as the headline number.

Flat-rate pricing

One rate for every card, such as 2.9% + 30¢. It is easy to forecast and ideal for low volume. The drawback: you pay the same on a cheap regulated debit card as on an expensive rewards card, so the processor keeps the difference on low-cost cards.

Interchange-plus pricing

The provider passes through actual interchange and network fees, then adds a fixed markup, for example 0.25% + 10¢. You benefit fully from cheap debit cards, and you can see exactly what the processor earns. This model usually becomes worthwhile once card volume reaches the tens of thousands of dollars a month, but the break-even point depends on your card mix.

Tiered pricing

Transactions are sorted into qualified, mid-qualified and non-qualified buckets, each with its own rate. The provider decides which bucket a transaction lands in, so tiered pricing is the least transparent. If your statement shows tiers, ask for interchange-plus instead.

Subscription or membership pricing

You pay a monthly fee and then interchange plus a small per-transaction charge. It can be cheap at high volume and expensive at low volume, so model your real numbers before signing.

Worked Example: A $2,400 Invoice Paid by Card

Suppose a consultant invoices $2,400 and the client pays online by card. Here is how the cost changes with the provider and the card.

• Flat rate 2.9% + 30¢: $2,400 × 2.9% = $69.60, plus $0.30 = $69.90. You receive $2,330.10.
• QuickBooks invoice rate 2.99%: $2,400 × 2.99% = $71.76. You receive $2,328.24.
• Square invoice 3.3% + 30¢: $2,400 × 3.3% = $79.20, plus $0.30 = $79.50. You receive $2,320.50.

Now take interchange-plus pricing. For illustration, assume a consumer credit card with interchange of 1.80% + $0.10, network fees of 0.15%, and a processor markup of 0.25% + $0.10:

1. Interchange: $2,400 × 1.80% = $43.20, plus $0.10 = $43.30.
2. Network fees: $2,400 × 0.15% = $3.60.
3. Processor markup: $2,400 × 0.25% = $6.00, plus $0.10 = $6.10.
4. Total: $43.30 + $3.60 + $6.10 = $53.00, an effective rate of 2.21%.

If the same client pays with a commercial card, interchange jumps to 2.70% + $0.10 = $64.90. Add the same $3.60 and $6.10 and the total becomes $74.60, or 3.11%. That is the hidden reason B2B invoices can cost more to process than consumer sales.

Finally, compare a bank payment. Through QuickBooks at 1%, the fee is $24.00. Through Stripe ACH at 0.8% capped at $5, the fee is just $5.00. On one invoice the gap to flat-rate card is $64.90; on 20 invoices a month it is about $1,298.

To show the client the exact total, you can build the invoice in our US invoice generator and add any applicable sales tax with the sales tax calculator.

How to Calculate Your Effective Rate

Your effective rate is the single number that tells you what card acceptance really costs. To calculate it:

1. Take one full monthly statement from your processor.
2. Add every fee: per-transaction charges, monthly fees, PCI fees, chargeback fees and payout fees.
3. Find total card volume processed in the same month.
4. Divide total fees by total volume and multiply by 100.
5. Repeat for three months and average the results.

Example: $1,398 in fees on $48,000 of card sales gives an effective rate of 2.91%. If a competing quote would lower it to 2.4%, you would save about $246 a month ($1,398 minus $1,152). Reconcile those fees against deposits each month; our guide to bank reconciliation shows how.

How to Read a Card Processing Statement

Statements are where processors hide costs, so it pays to know what you are looking at. The layout differs by provider, but most statements contain the same building blocks.

Summary section

This shows total card volume, number of transactions, total fees and net deposits for the month. It is enough to calculate your effective rate, but not to see why it moved.

Transaction or interchange detail

On interchange-plus plans, each card type and interchange program is listed with its rate and count. Look for transactions falling into "non-qualified" or "standard" programs. In Visa's 2026 schedule, non-qualified consumer credit costs 3.15% + $0.10 compared with well under 2% for many qualified programs, so a cluster of non-qualified lines usually signals a fixable problem, such as missing address verification on online payments or settling batches late.

Monthly and one-off fees

Check the account-level lines: monthly service fees, PCI compliance or non-compliance fees, statement fees, gateway fees and chargeback fees. A PCI non-compliance fee, for example, disappears once you complete the annual questionnaire, yet many small businesses pay it for years.

Questions to ask your provider

• Which pricing model am I on, and what exactly is your markup?
• Why did my effective rate change from last month?
• Which transactions downgraded to a higher rate, and why?
• Is there an early termination fee if I switch?

Ask in writing and keep the answers. If the provider cannot explain a line, that is a good reason to collect competing quotes.

How to Lower Credit Card Processing Fees

1. Offer bank payment on large invoices. ACH and wires cost a fraction of card fees. See how to accept ACH payments.
2. Avoid keying cards yourself. Keyed entry often costs more, as with QuickBooks at 3.5% versus 2.99% for invoice payments. Send a payment link instead; our guide on adding a payment link to an invoice walks through it.
3. Pass Level 2 and Level 3 data for B2B sales. Including tax amounts, PO numbers and line-item detail can qualify commercial cards for lower interchange on processors that support it.
4. Ask for interchange-plus at higher volume. Once monthly card volume is substantial, request a quote and compare it to your effective rate.
5. Consider a surcharge or cash discount. Many states allow credit card surcharges within limits. Read credit card surcharge rules before adding one.
6. Reduce chargebacks. Clear descriptions and receipts prevent disputes and their fees. Our guide to handling chargebacks covers prevention.
7. Use an early payment discount carefully. A discount for fast bank payment can cost less than card fees; see early payment discounts.

Should You Pass Credit Card Fees to Customers?

There are three common approaches. You can absorb the fee and build it into your prices, which keeps invoices simple. You can add a credit card surcharge where state law and network rules allow, which shifts the cost but may annoy some clients. Or you can offer a small discount for ACH or bank transfer, which is allowed broadly and nudges clients to the cheapest option.

Whichever you pick, put it in writing. State accepted payment methods and any surcharge or discount in your invoice payment terms, and show it clearly on each invoice. Our generator supports a fixed or percentage discount line, which makes a bank payment discount easy to display.

One more option suits freelancers who bill a few large invoices: accept cards but set a payment method preference by invoice size. For example, offer card payment on invoices under $1,000 and bank transfer only above that. On a $5,000 invoice, a 2.9% + 30¢ card fee is $145.30, while Stripe ACH would cost $5.00, so a simple size rule protects most of the margin without turning small clients away.

Choosing a Processor for Invoice Payments

For most freelancers and small businesses, a flat-rate provider with low monthly costs is the right start. Prioritise these points:

• Invoice card rate and ACH rate, not just the in-person rate.
• Payout speed and the cost of instant deposits.
• Chargeback fees and dispute tools.
• Support for international cards and currency conversion if you bill abroad.
• How easily payments match to invoices in your bookkeeping.
