Tiered vs. Interchange-Plus Pricing: Which Actually Costs Less?

Tiered plans bucket transactions into qualified, mid-qualified, and non-qualified. Your sales rep highlights the qualified rate. Many of your transactions may not land there. Rewards cards, keyed entries, and corporate cards often downgrade into pricier buckets without a clear alert at checkout.

What interchange-plus shows you

Interchange-plus lists the network cost for each category, then adds a consistent processor markup. The statement is longer, but auditable. You can see when interchange itself rises versus when markup changes. That transparency is why many merchants switch after their first honest statement review.

Neither model is free. Interchange-plus can still carry monthly line items, PCI fees, and gateway charges. The win is visibility, not magic.

When tiered sometimes looks cheaper on paper

Very small volume with a narrow card mix and almost all in-person chip transactions might stay in qualified buckets often enough that tiered math looks fine—for a while. Add ecommerce, phone orders, or B2B cards and the spread usually widens.

One number decides it: effective rate

Divide total fees by card sales for the same month. That percentage is the only comparison that matters. Run it on your current plan, then ask a transparent provider to model your statement data the same way.

• Ignore “starting at” qualified rates in proposals.
• Include every fee line, not just discount.
• Compare at least one busy month and one slow month.

Omega Bank Card uses interchange-plus pricing and walks merchants through the math before they switch. If tiered is truly cheaper for your mix, we will say so. Usually the effective rate tells a different story.

Pick pricing you can audit. Merchants who know their effective rate negotiate from strength and spot drift before it becomes a year of overpaying.
