Quick Answer:
Average credit card processing fees range from 1.5% to 3.5% per transaction, depending on the card network, card type, pricing model, and your industry. The true cost includes interchange fees (1.29–2.80%), assessment fees (0.13–0.15%), and your processor’s markup.
Interchange-plus pricing is almost always the cheapest option for established businesses. Flat-rate pricing (like Stripe at 2.9% + $0.30) is simpler but more expensive at scale.
High-risk merchants typically pay 3–5%+ due to higher interchange categories, increased processor markups, and additional fees like rolling reserves and chargeback fees.
Key Takeaways
- Interchange fees are non-negotiable — they’re set by Visa, Mastercard, and the other card networks. The only fees you can negotiate are your processor’s markup.
- Switching from flat-rate to interchange-plus pricing saves most businesses 15–30% on processing costs. At $50K/month in volume, that’s $250–$750/month in savings.
- Your MCC directly affects your interchange rates. A misclassified MCC can cost you thousands in excess fees annually.
- High-risk merchants pay more, but “how much more” depends entirely on your processor. Some high-risk processors charge 2x what others do for the same volume.
- ACH payments cost $0.25–$1.00 per transaction vs. 2–3.5% for credit cards. For high-ticket items, ACH saves dramatically.
What Are Credit Card Processing Fees?
Credit card processing fees are the costs merchants pay every time a customer pays with a credit or debit card. These fees are split between multiple parties — the card network, the issuing bank, and your payment processor — and they’re deducted from your sale before the money reaches your bank account.
The average credit card processing fee is 1.5–3.5% of the transaction amount plus a small fixed fee ($0.10–$0.30) per transaction. But that range is wide because the actual cost depends on the card network, card type, transaction method, your industry, and your processor’s pricing model.
Understanding what you’re actually paying — and where each dollar goes — is the first step to lowering your costs. For a deeper dive into reading your monthly statement, see our guide on how to read your merchant statement.
The Three Components of Every Processing Fee
1. Interchange Fees (The Largest Cost)
Interchange fees are paid to the customer’s issuing bank (Chase, Bank of America, etc.) on every transaction. They typically make up 70–80% of your total processing cost.
These fees are set by the card networks (Visa, Mastercard) and published twice a year. They are non-negotiable — no processor can give you a lower interchange rate. The rate depends on the card type, transaction method, and your MCC.
2. Assessment Fees (Card Network Fees)
Assessment fees are charged by the card networks themselves (Visa, Mastercard, American Express, Discover) for using their network. These are small but add up at volume:
- Visa: 0.14% of volume + $0.0195 per transaction
- Mastercard: 0.1275% of volume + $0.0195 per transaction (Mastercard fees and charges vary slightly by region)
- Discover: 0.13% of volume + $0.0195 per transaction
- American Express: varies by program (OptBlue vs. direct)
Assessment fees are also non-negotiable.
3. Processor Markup (The Only Negotiable Part)
This is what your payment processor charges on top of interchange and assessments. It’s their profit margin, and it’s the only part of your processing cost you can negotiate.
The markup varies enormously between processors and pricing models. Stripe charges a flat 2.9% + $0.30 that includes everything. A dedicated merchant account might charge interchange + 0.20% + $0.10 per transaction. The difference at scale is significant.
Average Interchange Rates by Card Network and Type
These are representative averages for US domestic transactions. Actual rates vary by MCC, transaction type, and card product:
Card Type | Visa | Mastercard | Amex | Discover |
Consumer Credit | 1.65%+$0.10 | 1.58%+$0.10 | 2.30%+$0.10 | 1.56%+$0.10 |
Consumer Debit | 0.80%+$0.15 | 0.80%+$0.15 | — | 1.35%+$0.15 |
Rewards Credit | 1.95%+$0.10 | 1.90%+$0.10 | 2.40%+$0.10 | 1.71%+$0.10 |
Corporate | 2.20%+$0.10 | 2.35%+$0.10 | 2.50%+$0.10 | 2.30%+$0.10 |
Card Not Present | 1.80%+$0.10 | 1.73%+$0.10 | 2.40%+$0.10 | 1.65%+$0.10 |
High-Risk MCC | 2.40–2.80% | 2.25–2.65% | 2.70%+ | 2.40%+ |
Note: These are interchange rates only. Your total cost also includes assessment fees and processor markup. Rates current as of 2026 — Visa and Mastercard update interchange tables in April and October each year.
Your Merchant Category Code (MCC) determines which interchange category you fall into. A misclassified MCC can put you in a higher-cost category. See our guide on how your MCC affects your processing costs.
Pricing Models Compared: Flat-Rate vs. Interchange-Plus vs. Tiered
How your processor charges you matters as much as what the interchange rates are. The pricing model determines your total credit card processing charges.
Flat-Rate Pricing
One rate for everything. Stripe charges 2.9% + $0.30. Square charges 2.6% + $0.10 for in-person. PayPal charges 2.99% + $0.49.
Pros: Simple and predictable. No surprises on your statement.
Cons: You’re overpaying on every debit card transaction (where interchange is only 0.80%) and subsidizing rewards card transactions. The simplicity costs you money at scale.
Best for: New businesses under $10,000/month in volume, or businesses that want a backup processor.
Interchange-Plus Pricing
Your processor charges the actual interchange rate plus a fixed markup. Example: interchange + 0.20% + $0.10 per transaction.
Pros: The cheapest option for most established businesses. Full transparency — you can see exactly what interchange is costing you and what the processor is charging.
Cons: Statements are more complex. Monthly costs vary because interchange rates differ by card type.
Best for: Any business processing over $10,000–$15,000/month. The savings over flat-rate are typically 15–30%.
For a detailed comparison, see our guide on interchange-plus vs. tiered vs. flat-rate pricing.
Tiered Pricing
Transactions are grouped into “qualified,” “mid-qualified,” and “non-qualified” tiers, each with a different rate.
Pros: None, really. This is the pricing model that benefits the processor, not you.
Cons: The processor defines which tier each transaction falls into, and the qualification criteria are buried in fine print. The advertised “qualified” rate looks great but most transactions end up in the more expensive tiers.
Best for: No one. If you’re on tiered pricing, switching to interchange-plus will almost certainly save you money.
What Credit Card Processing Fees Actually Look Like by Business Type
This is DPN’s perspective that no other processing fees article provides — what do fees actually look like for different types of businesses?
Business Type | Volume/Mo | Eff. Rate | Monthly Cost | Notes |
Low-risk retailer (in-person) | $50K | 1.8–2.2% | $900–$1,100 | Mostly debit + chip, lowest rates |
E-commerce (low-risk) | $50K | 2.2–2.8% | $1,100–$1,400 | Card-not-present adds ~0.3% |
SaaS / Subscriptions | $50K | 2.5–3.0% | $1,250–$1,500 | Recurring billing, mixed card types |
Supplements / Nutra | $50K | 3.0–4.5% | $1,500–$2,250 | High-risk MCC, higher markups |
CBD / Cannabis | $50K | 4.0–6.0% | $2,000–$3,000 | Very high-risk, limited processors |
Travel / Ticketing | $50K | 3.5–5.0% | $1,750–$2,500 | Advance purchase risk, high chargebacks |
Adult / Gaming | $50K | 4.0–7.0% | $2,000–$3,500 | Highest risk category |
Effective rates include interchange + assessments + processor markup. Ranges reflect typical pricing across multiple processors. Your actual rate depends on your specific processor, chargeback history, and processing history.
If you’re in a high-risk industry and paying above these ranges, you may be overpaying. See DirectPayNet’s high-risk merchant account fees guide for what you should expect.
How to Lower Your Credit Card Processing Fees
1. Switch to Interchange-Plus Pricing
If you’re on flat-rate or tiered pricing and processing over $15K/month, switch. The savings are immediate and significant. A business processing $50K/month at Stripe’s 2.9% pays $1,450/month. The same volume on interchange-plus at an effective rate of 2.2% pays $1,100. That’s $350/month or $4,200/year saved.
2. Verify Your MCC
A misclassified MCC means you’re paying interchange rates for a category that isn’t yours. Contact your processor and confirm your MCC. If it’s wrong, get it changed. See our guide on Merchant Category Codes.
3. Negotiate Your Processor’s Markup
Interchange and assessment fees are fixed. But your processor’s markup — the percentage and per-transaction fee they charge on top — is fully negotiable. If you’ve been processing for 6+ months with a clean chargeback history, you have leverage. Ask for a lower markup. See our guide on avoiding merchant account fee rip-offs.
4. Add ACH as a Payment Option
ACH bank transfers cost $0.25–$1.00 per transaction regardless of amount. For a $1,000 sale, that’s $1.00 via ACH vs. $29.30 via Stripe. For high-ticket items and recurring billing, ACH saves dramatically. See our full guide on ACH payment processing.
5. Reduce Chargebacks
High chargeback rates directly increase your processing costs. Processors add surcharges, impose rolling reserves, and raise markups for merchants with chargeback rates above 0.5%. Keeping your chargeback ratio under 0.5% protects your rates. See our guide on how to dispute chargebacks as a merchant.
6. Avoid “Free” or Zero-Fee Processing
Zero-fee processing sounds attractive but it shifts costs to customers through surcharges. This increases chargebacks (customers dispute unexpected fees), damages customer trust, and creates compliance headaches with state surcharge laws that vary widely.
Credit Card Processing Fees for High-Risk Merchants
If you’re in a high-risk industry — supplements, CBD, travel, adult, gambling, subscription services, or any category on Stripe’s restricted list — your processing fees are higher than the averages above. Here’s why and what you can do about it.
Why high-risk fees are higher: Higher interchange categories for risky MCCs, larger processor markups to compensate for chargeback risk, rolling reserves (typically 5–10% held for 180 days), monthly monitoring fees, and chargeback fees ($25–$100 per dispute).
What you can control: Your processor’s markup (shop around — high-risk processors vary dramatically), your chargeback ratio (lower ratio = lower fees), your MCC (correct classification matters even more at high-risk rates), and adding ACH to reduce the volume going through expensive card processing.
DirectPayNet specializes in high-risk merchant accountswith competitive interchange-plus pricing. If you’re paying over 4% on a merchant account, we can likely do better. See what high-risk merchant account fees should actually look like.
Credit Card Terminal and Machine Fees
Beyond per-transaction fees, merchants using physical credit card terminals or credit card machines pay additional costs:
- Terminal purchase or lease: $200–$1,000 to buy, or $20–$50/month to lease
- Monthly gateway fee: $10–$25/month for online payment gateway access
- PCI compliance fee: $80–$120/year (or monthly equivalent)
- Statement fee: $5–$10/month
- Batch fee: $0.10–$0.30 per daily batch settlement
Always buy your terminal outright rather than leasing. A terminal lease can cost $1,200–$2,400 over a 48-month contract for a device worth $300. See our guide on optimizing your processing statement to identify and eliminate unnecessary fees.
Frequently Asked Questions
The average credit card processing fee is 1.5–3.5% per transaction, depending on the card type, card network, transaction method, and your pricing model. Debit cards are cheapest (~0.80% + $0.15). Rewards credit cards are most expensive (~1.95% + $0.10 at interchange alone). Your processor’s markup adds another 0.15–1.0% on top.
Most merchants pay an effective rate of 2.0–3.0% across all transactions. A business processing $50,000/month at a 2.5% effective rate pays $1,250/month in credit card payment processing fees. High-risk merchants may pay 3.5–5.0%+ depending on their industry and processor.
Partially. Interchange fees and assessment fees are set by the card networks and cannot be negotiated. Your processor’s markup — the percentage and per-transaction fee they charge on top of interchange — is fully negotiable. If you’ve been processing for 6+ months with low chargebacks, ask for a rate review.
Interchange is the fee paid to the customer’s issuing bank. It’s set by the card networks and non-negotiable. Markup is the fee your processor charges on top of interchange for their services. Interchange is the same regardless of which processor you use. Markup is where processors compete — and where you can save money by shopping around.
Mastercard charges assessment fees of 0.1275% of volume plus $0.0195 per transaction. On top of that, Mastercard’s interchange rates range from 0.80% for consumer debit to 2.65% for high-risk categories. The Mastercard processing fee you actually pay also includes your processor’s markup on top of these base costs.
The most common reasons: you’re on flat-rate or tiered pricing instead of interchange-plus, your MCC is misclassified, you’re processing mostly rewards or corporate cards (higher interchange), you’re in a high-risk industry, or your processor’s markup is above market rate. See our guide on lowering your credit card processing fees.
Small businesses typically pay 2.5–3.5% per transaction because they’re often on flat-rate pricing (Stripe, Square, PayPal) and lack the volume to negotiate lower markups. Once you hit $10,000–$15,000/month in processing volume, switching to a dedicated merchant account with interchange-plus pricing usually saves 15–30%.
Get the Right Rate for Your Business
Credit card processing fees don’t have to eat your margins. The difference between the wrong processor and the right one can be $5,000–$15,000 per year for a mid-volume business.
DirectPayNet helps merchants — especially high-risk businesses — get competitive interchange-plus pricing, verify their MCC, and add ACH to reduce costs on high-ticket transactions. Whether you’re on Stripe paying 2.9% or on a high-risk processor paying 5%, we can help you pay less.
