Card Brand Assessment Fees: The Hidden Costs Processors Don’t Explain

Beyond interchange, every card transaction includes a layer of fees charged by the card networks themselves — Visa, Mastercard, American Express, and Discover. These assessment and scheme fees are separate from interchange and from your processor’s markup, but they show up on your merchant statement in ways that are easy to miss or misunderstand. Understanding them helps you evaluate processor pricing more accurately.

What Are Card Brand Assessment Fees?

Assessment fees (also called scheme fees) are charges levied by the card networks for using their payment rails. Every transaction — whether processed at 2.9% flat rate or IC++ — incurs these fees. On blended or flat-rate plans, assessment fees are bundled into the overall rate. On IC++ plans, they appear as a separate pass-through line item.

Visa Assessment Fees (Key Ones)

• Visa Credit Assessment: 0.13% on credit transactions
• Visa Debit Assessment: 0.13% on consumer debit transactions
• Visa Fixed Acquirer Network Fee (FANF): A monthly fee based on merchant location count and MCC — charged per physical or digital location
• Visa International Service Assessment: Additional fee on cross-border transactions (typically 0.40%–1.40% depending on currency)
• Visa Misuse of Authorization: A fee when authorizations aren’t followed by settlement within the required timeframe

Mastercard Assessment Fees (Key Ones)

• Mastercard Credit Assessment: 0.1375% on credit transactions
• Mastercard Network Access and Brand Usage (NABU): $0.0195 per transaction
• Mastercard Cross-Border Assessment: 0.40%–0.60% on international transactions
• Mastercard Digital Enablement Fee: 0.01% on ecommerce and contactless transactions

Why These Fees Change Quarterly

Visa and Mastercard update their fee schedules twice per year (April and October). Processors on IC++ pricing pass these changes through directly to merchants — meaning your processing costs can increase with no action from your processor. On flat-rate pricing, the processor absorbs network fee changes within their margin.

How Blended-Rate Processors Obscure These Fees

On a blended or flat-rate plan, assessment fees are bundled into a single rate and never appear as separate line items. This isn’t inherently deceptive — but it means merchants can’t verify whether assessment fee increases are being passed through or absorbed by the processor.
