What percentage applies?
Understand the merchant-facing rate and where it changes by transaction or pricing category.

Processing pricing models
Five ways processing fees can be presented. See how each works before comparing your options.
Start with the short version. Open any model for its explanation.
Underlying interchange and network costs are shown separately from an explicit processor markup.
Eligible transactions are presented through a simplified merchant-facing rate or pricing structure.
Transactions are grouped into pricing categories such as qualified, mid-qualified, or non-qualified.
Pass-through processing costs are paired with recurring membership, subscription, or transaction fees.
A negotiated mix of percentage, per-item, fixed, or program economics.
A simpler structure does not automatically mean a lower total cost.
Two proposals can present pricing differently and still produce very different monthly results.
Understand the merchant-facing rate and where it changes by transaction or pricing category.
Small transaction fees can add up when transaction count is high.
Review applicable monthly, gateway, software, equipment, PCI, and other fixed charges.
Card type, channel, ticket size, and transaction details can affect the underlying cost.
Use these three checks when reviewing a proposal.
Total processing cost. Compare the full monthly expense, not just the headline percentage.
Effective rate. Use total processing fees divided by total card sales as a high-level comparison.
Transaction mix. Card type, acceptance channel, ticket size, and transaction count shape the result.
Statement clarity. Make sure you can understand what changed and why each month.
Business requirements. Technology, billing workflow, customer experience, and support still matter.
Tradeoffs. Simpler pricing is not automatically cheaper, and detailed pricing is not automatically better.
Interchange is one underlying component of card-processing cost and can vary with transaction details.
Turn total processing expense into one comparable percentage, then use the statement to understand why.
