Understanding credit card processing fees is the first step to reducing them.

This comprehensive guide breaks down every fee you'll encounter, what's reasonable, and how to minimize your costs.

The Three Components of Processing Fees

Every credit card transaction involves three types of fees.

1. Interchange Fees (70-80% of your cost)

Who gets it: Card-issuing banks (Chase, Citi, etc.)

What it costs: 1.15% - 3.25% depending on card type

Can you negotiate? No - these are fixed by Visa/Mastercard

2. Assessment Fees (5-10% of your cost)

Who gets it: Card networks (Visa, Mastercard, Amex)

What it costs: 0.13% - 0.15%

Can you negotiate? No - these are fixed

3. Processor Markup (15-25% of your cost)

Who gets it: Your payment processor

What it costs: 0.10% - 1.00%+

Can you negotiate? YES! This is where you save money.

How to Calculate Your True Cost

Step 1: Find your total monthly fees

Step 2: Find your total monthly sales volume

Step 3: Calculate: Total Fees ÷ Total Volume × 100 = Effective Rate

Is your rate good?

• Below 2.0%: Excellent

• 2.0-2.5%: Good

• 2.5-3.0%: Average

• Above 3.0%: You're overpaying

Frequently asked questions

What's a good effective rate for my business?

For most businesses, a healthy effective rate is 2.0-2.5%. Restaurants and e-commerce may run slightly higher (2.3-2.8%) due to card type mix. Anything above 3.0% means you're likely overpaying.

Why do rewards cards cost more to process?

Banks fund cardholder rewards (cashback, points) through higher interchange fees. A 2% cashback card costs merchants about 0.4% more to process than a basic card.

How much can I realistically save?

PayPro clients save an average of 24% on processing costs, or about $847/month. Businesses processing over $50,000/month typically save $500-3,000+ monthly.
