What Are Credit Card Processing Fees?

When a customer pays with a credit card, there’s more to it than just swiping or tapping. Credit card processing fees are the behind-the-scenes costs that come with every transaction, and they’re divided among a few key players involved in the payment process.

Here’s a quick look at how it all breaks down:

  • Interchange Fees: These go to the bank that issued the customer’s card. Think of it as the bank’s cut for facilitating the transaction.
  • Assessment Fees: Card networks like Visa and Mastercard charge these fees to keep their systems running smoothly.
  • Markup Fees: This is where your payment processor or merchant service provider earns their profit.

Credit Card Processing Rates and Fees: Breaking Down the Cost

Understanding the pricing models for processing fees can save you money.

Here’s a detailed look at the common structures in 2025:

Flat-Rate Pricing

Predictable but typically higher, flat-rate pricing works well for businesses with lower transaction volumes.

Pros: Simplicity, no surprises.

Cons: Often more expensive than other models for larger businesses.

Interchange-Plus Pricing

Considered the most transparent model, you pay the interchange fee plus a small, fixed markup.

Pros: Lower costs for higher volumes.

Cons: Requires a closer look at your statements to understand costs.

Tiered Pricing

Merchants get categorized into tiers (qualified, mid-qualified, non-qualified) based on transaction types. Each tier has its own rate.

Pros: Potentially better rates for qualified transactions.

Cons: Often less transparent and can lead to hidden costs.

How to Calculate Credit Card Processing Fees (With Real Examples)

Calculating fees isn’t as complicated as it sounds if you have a formula.

Here’s a simple one to use:

Fee = Transaction Amount x (Processing Rate) + Per-Transaction Fee

Worked Examples

1. $100 Purchase (2.9% Flat Rate)

Fee = $100 x 2.9% = $2.90

2. $500 Purchase (Interchange Plus 1.8% + $0.10)

Fee = ($500 x 1.8%) + $0.10 = $9.10

3. $1,000 Purchase (Tiered, Non-Qualified Rate 3.2%)

Fee = $1,000 x 3.2% = $32.00

Clear calculations like these help businesses see the impact of fees on their bottom line.

What Is the Average Fee for Credit Card Processing?

Credit card processing fees can often feel like a mystery, but understanding the averages and how they apply to your business can help you manage costs more effectively. These fees typically fall between 1.5% and 3.5%, as noted by Capital One.

Breaking Down Credit Card Processing Fees

There are various fee models in play, but they all boil down to how much you’re charged per transaction. This includes interchange fees (paid to card issuers), assessment fees (for the card networks), and processing fees (your payment processor’s cut).

Here’s what this might look like on a $100 sale under different scenarios:

  • Flat-Rate Pricing: Your processor charges a fixed percentage plus a per-transaction fee. For example, at 2.9% + $0.30, you’d pay $3.20 in total fees. This model is common with processors like Stripe.
  • Interchange Plus Pricing: You’re charged the baseline interchange fee (say 1.8% for a Visa card) plus a markup (e.g., 0.5%). On a $100 transaction, you’d pay $2.30. This can save you money but requires a more detailed review to project costs.
  • Tiered Pricing: Rates depend on factors like card type and how the transaction is processed. For example, a “qualified” swipe might be 1.7%, while a “non-qualified” online payment with a rewards card might push toward 3.5%.

Industry Examples

The business type can significantly impact your fees:

  • Restaurants: Often incur lower rates for in-person transactions compared to online orders because of reduced fraud risk. On average, they might pay around 2% per transaction.
  • Ecommerce Businesses: Online-only businesses typically see higher rates, often between 2.3% and 3.5%, because of greater fraud risk and stricter security measures required by eCommerce payment processors.

Types of Available Credit Card Readers

Industry Benchmarks

Where your business falls in this spectrum largely depends on how you operate and your transaction size.

Here’s a quick comparison:

  • Retail vs. Online vs. Mobile: Brick-and-mortar businesses generally see lower fees (1.5%–2.4%) thanks to chip card technology. Mobile payments, such as those through Square readers, tend to hover around 2.6% + $0.10 per swipe. Online transactions face the highest rates due to fraud risks.
  • Small Business vs. Enterprise: Smaller businesses often pay more per transaction due to limited negotiating power and lower transaction volumes. For instance, a small retail shop may pay closer to 3%, whereas a large enterprise retailer processing millions annually might negotiate fees around 1.5%.

A Quick Heads-Up

While these strategies can help lower fees for credit card processing, make sure you’re familiar with your state’s laws. Some states, for instance, have strict regulations on adding surcharges or require transparency in how discounts are applied. Following the rules is key to staying compliant while saving money.

Are Credit Card Processing Fees Tax Deductible?

Yes, credit card processing fees are typically tax deductible. The IRS views these fees as a necessary business expense, making them eligible for deductions. To maximize savings, ensure you record and categorize these expenses properly during tax season.

Sales Tax on Credit Card Processing Fees

Whether these fees are subject to sales tax depends on your state. Some states, like California, don’t tax them, while others might, especially if the fees are bundled with other taxable services. It’s vital to check your state’s specific rules on sales tax on credit card processing fees to stay compliant.

Understanding the tax treatment of these fees helps you manage costs effectively while staying organized for both state and federal regulations.

The Future of Credit Card Processing Fees

Credit card processing fees are heading into a time of transformation, with technology, innovation, and regulations leading the charge.

Here’s what to keep an eye on:

AI’s Role in Fraud Prevention

AI and machine learning are making big waves in stopping fraud before it happens. These tools can reduce fraud-related costs, but the investment in such cutting-edge solutions might initially raise fees. Over time, they could streamline operations and lead to savings.

Crypto and Instant Payment Alternatives

With the rise of cryptocurrencies and instant payment platforms, businesses have more ways to accept payments with lower processing fees. Offering customers these faster, more affordable choices could reduce reliance on traditional credit card systems.

Swipe Fee Reform and Other Regulations

On the regulatory front, swipe fee reform is creating buzz. Lawmakers are debating rules that could limit interchange fees, potentially lowering the burden on merchants. Staying on top of these changes is essential for planning your payment strategies.
