Tiered vs Interchange-Plus: Which Is Better?
The Two Most Common Pricing Models Explained
When it comes to credit card processing fees, how you are charged matters just as much as what you are charged. The two most common pricing structures are Tiered Pricing and Interchange-Plus Pricing. Understanding the difference can save you thousands of dollars per year.
What Are Credit Card Interchange Fees?
Before comparing pricing models, it helps to have interchange fees explained in plain terms. Interchange is the fee the card networks (Visa, Mastercard, Discover) set and collect on every transaction — your processor passes it through and adds a markup on top. That is the simplest interchange fees meaning to remember, and it is also the key difference between credit card processing fees and interchange fees: interchange goes to the card-issuing bank, while your processor's markup is the negotiable part. Interchange rates for credit cards vary by card type, with the average interchange fee on premium rewards and business cards running meaningfully higher than on a basic consumer card — which is why your card mix has such a big effect on your overall rate. You cannot eliminate credit card interchange fees, but the right pricing model and a few good habits show you how to reduce interchange fees you actually pay on each interchange credit card transaction.
Tiered Pricing: The "Simplified" Trap
How It Works
Tiered pricing groups all credit card transactions into three buckets. The tiered rates meaning is simple on the surface — three price levels — but which bucket each sale lands in is decided by the processor:
- Qualified: The lowest rate, typically 1.5%-2.0%
- Mid-Qualified: A middle rate, typically 2.0%-2.5%
- Non-Qualified: The highest rate, typically 2.5%-3.5%
Processors market this as "simple" pricing because you only have three rates to understand.
The Problem
The problem is that your processor decides which bucket each transaction falls into — and surprise, most transactions end up in the more expensive buckets.
That "low" qualified rate you were promised? It often only applies to basic debit cards swiped in person with signature. Rewards cards, corporate cards, keyed transactions, and international cards all get "downgraded" to higher tiers.
Real-world example: A restaurant processing $30,000/month was quoted a 1.69% qualified rate. Sounds great, right? But their actual effective rate was 3.2% because 70% of their transactions were classified as mid-qualified or non-qualified.
Who Benefits from Tiered Pricing?
Processors. That is it. Tiered pricing gives processors maximum flexibility to pad their margins while keeping merchants confused.
Interchange-Plus: The Transparent Alternative
How It Works
Interchange-Plus pricing separates the actual cost of processing (interchange) from the processor's markup:
- Interchange: The non-negotiable fee set by Visa/Mastercard (varies by card type)
- Plus: Your processor's markup (typically 0.1%-0.5% + $0.05-$0.15 per transaction)
You pay the true interchange cost for each card type, plus a consistent markup from your processor. These interchange plus rates are the most transparent structure in merchant services, breaking your credit card merchant charges into a clear cost-plus-markup instead of one blended merchant service fee — interchange plus pricing in merchant services simply means cost passed through plus a fixed markup that never changes.
Why It is Better
- Transparency: You can see exactly what you are paying and why
- Consistency: The processor's margin stays the same regardless of card type
- Fairness: You benefit when customers use lower-cost cards (like debit)
- Verifiable: You can check interchange rates against published Visa/Mastercard tables
Real-world example: The same restaurant switched to Interchange-Plus at IC + 0.25% + $0.10. Their effective rate dropped to 2.4%, saving over $2,400 per year.
The Verdict: Interchange-Plus Pricing vs Tiered Pricing
In the head-to-head of interchange plus pricing vs tiered pricing, Interchange-Plus wins, hands down. It is the only pricing model that aligns your processor's interests with yours.
If your processor will not offer Interchange-Plus pricing, ask why. If they claim it is "too complicated," that is code for "we make more money keeping you confused."
What About Flat-Rate Pricing?
You might have heard of flat-rate pricing from companies like Square (2.6% + $0.10 for every transaction). While simple, it is usually not the best deal for businesses processing more than $10,000/month. You end up overpaying on low-cost transactions to subsidize the simplicity.
How to Switch
Already stuck with tiered pricing? You do not necessarily need to switch processors. We can often negotiate with your current provider to convert you to Interchange-Plus pricing — keeping your existing setup while lowering your card processing fee totals and overall payment processing costs.
