Payment gateway fees vary widely depending on your business type, sales volume, and the processor you choose — but most small businesses pay between 2.2% and 3.5% per transaction, plus a monthly fee of $0 to $30.
The cost you pay is not one number. It is a combination of three separate charges: a percentage of each sale (called the discount rate), a flat fee per transaction, and often a monthly account fee. A coffee shop processing a $5 card payment might pay 15 cents in fees. An online retailer processing a $200 order might pay $6. The difference comes down to your industry, how you accept cards, and which processor you use.
Understanding what you are actually paying for matters because the difference between two processors can cost you hundreds or thousands of dollars per year. A business processing $50,000 in monthly sales could pay anywhere from $1,100 to $2,000 per month depending on which gateway they choose — that is a real difference in profit.
Key Takeaways
- Most payment gateways charge a percentage of each sale (2.2% to 3.5%), a per-transaction fee ($0.20 to $0.30), and sometimes a monthly account fee ($0 to $30).
- In-person card payments (swiped or inserted) usually cost less than online payments because fraud risk is lower.
- Your monthly sales volume matters — processors often lower rates for businesses processing more than $10,000 per month.
- Comparing total monthly cost across three processors is more useful than comparing a single rate, because each processor bundles fees differently.
- Some gateways charge extra for features like invoicing, recurring billing, or chargebacks, so read the full fee schedule before signing up.
The three fees that make up your total cost
Every payment gateway charges you in the same basic way, but they package it differently. The discount rate is a percentage of each sale — usually 2.2% to 3.5% — that goes to the processor, the card network (Visa or Mastercard), and your bank. This is the largest fee for most businesses.
The per-transaction fee is a flat amount charged on top of the percentage — typically $0.20 to $0.30 per card payment. This covers the cost of routing the transaction through the payment network. A business processing many small sales (like a coffee shop) feels this fee more than a business processing fewer large sales (like a consulting firm).
The monthly account fee ranges from $0 to $30 and covers the cost of maintaining your account. Some processors waive this if you process a minimum amount each month. Others charge it no matter what. A few charge nothing monthly but make up the difference with higher per-transaction fees.
How your business type affects what you pay
Payment processors charge different rates depending on how risky they think your business is. In-person payments (where the customer shows up with a card) are considered lower risk because the card is physically present and the customer is right there. These usually cost 1.5% to 2.2% plus a per-transaction fee.
Online payments (where you never see the card) are considered higher risk because fraud is easier. These usually cost 2.9% to 3.5% plus a per-transaction fee. Mail order and phone order payments fall somewhere in between.
Certain industries pay more because they have higher fraud rates or higher chargeback rates (when a customer disputes a charge). Travel, subscription services, and high-ticket items often cost 3% to 4% or more. Nonprofits and educational institutions sometimes get discounts and may pay 1.5% to 2.5%.
What changes your rate based on volume
Most processors offer lower rates once you reach certain sales thresholds. A business processing $5,000 per month might pay 2.9% plus $0.30 per transaction. The same business processing $50,000 per month might negotiate down to 2.4% plus $0.25 per transaction. The difference is that high-volume businesses are more valuable to the processor and represent less risk per dollar processed.
You do not usually have to ask for a lower rate — many processors automatically adjust your rate based on your monthly volume. Others require you to call and negotiate. If you are processing more than $10,000 per month, it is worth calling three processors and asking what rate they would offer you based on your actual numbers.
Hidden fees that add up quickly
Beyond the basic transaction fees, most gateways charge for specific features or situations. A chargeback fee (usually $15 to $100) is charged when a customer disputes a charge with their bank. A monthly minimum fee applies if you do not process enough volume — some gateways charge $25 to $50 if your monthly fees fall below that amount. A PCI compliance fee ($5 to $15 per month) covers the cost of keeping your account find.
Some gateways charge extra for invoicing, recurring billing, or reporting features that other gateways include for free. A few charge a fee to close your account or transfer your data to another processor. Read the full fee schedule on the processor's website before you sign up — the headline rate is never the whole story.
How to compare what you will actually pay
The best way to compare processors is to calculate your total monthly cost with each one, using your actual sales numbers. Take your average monthly sales and multiply by the discount rate, then add (number of transactions × per-transaction fee), then add the monthly account fee. Do this for three processors you are considering.
For example: if you process $30,000 per month in 300 transactions, Processor A at 2.9% plus $0.30 per transaction plus $10 monthly would cost you $870 plus $90 plus $10 = $970 per month. Processor B at 2.7% plus $0.25 per transaction plus $0 monthly would cost you $810 plus $75 plus $0 = $885 per month. That $85 difference per month is $1,020 per year — real money.
Call the sales team at each processor and give them your actual numbers. Ask them to quote you a rate based on your business type, sales volume, and how you accept payments. Get the quote in writing. Then do the math yourself to verify it.
When to negotiate or switch processors
If you have been with the same processor for a year and your sales have grown, your rate may not have dropped automatically. Call and ask if you may have access to for a lower rate based on your current volume. Many processors will lower your rate to keep you as a customer rather than lose you to a competitor.
If you are paying significantly more than the range for your industry (2.2% to 3.5% for most online businesses), it is worth getting quotes from competitors. Switching processors takes a few days of setup work but can save you hundreds of dollars per year. The cost of switching is usually just the time it takes to update your website and accounting software.
Before you switch, check whether your current processor charges a termination fee. Most do not, but some charge $50 to $300 to close your account. Factor that into your decision — if switching saves you $100 per month but costs $300 to leave, you break even after three months.
Frequently Asked Questions
Is there a standard rate I should expect to pay?
Most small businesses processing online payments pay between 2.7% and 3.2% plus $0.25 to $0.30 per transaction. In-person payments usually cost 1.5% to 2.2% plus a per-transaction fee. Your actual rate depends on your industry, sales volume, and how you accept cards. Get quotes from three processors using your real numbers rather than comparing headline rates.
Why do different processors charge different amounts for the same thing?
Processors price based on their own cost structure, the risk they perceive in your business, and how much they want your business. A processor targeting high-volume retailers might offer lower rates but charge higher monthly fees. A processor targeting startups might charge higher per-transaction fees but no monthly minimum. Neither is wrong — they are just different business models.
Can I negotiate my payment gateway rate?
Yes, especially if you process more than $10,000 per month or have been with a processor for over a year. Call the sales team, give them your actual numbers, and ask what rate they can offer. Many processors will lower your rate to keep you. Get any quote in writing before you commit.
What happens if I process fewer transactions than I expected?
You still pay the per-transaction fee on every payment you process, plus the monthly account fee if your processor charges one. Some processors have a monthly minimum fee — if your transaction fees do not add up to that amount, you pay the minimum instead. Check your processor's policy before signing up.
Should I choose the processor with the lowest percentage rate?
No. The lowest percentage rate is only one part of your total cost. A processor with 2.5% but $0.50 per transaction might cost more than a processor with 2.9% but $0.20 per transaction, depending on your average transaction size. Calculate your total monthly cost with each processor using your actual numbers, then compare.
