A practical guide to understanding interchange, comparing pricing models, and keeping more of what you earn.
Every time a customer swipes, dips, or taps a credit card at your business, a percentage of that transaction goes to a chain of intermediaries before the remaining funds land in your bank account. Understanding where that money goes is the first step toward reducing what you pay.
Processing fees are made up of three components:
On a typical $100 credit card transaction, you might pay $1.80 in interchange, $0.14 in assessments, and $0.30–$0.80 in processor markup — totaling $2.24–$2.74 in fees. Over a year, those percentages compound into thousands or tens of thousands of dollars.
Not all pricing structures are created equal. The model your processor uses determines how transparent your fees are — and how much you actually pay.
| Feature | Flat-Rate | Tiered | Interchange-Plus |
|---|---|---|---|
| How it works | One fixed rate for all transactions (e.g., 2.9% + $0.30) | Transactions sorted into qualified, mid-qualified, and non-qualified tiers | Actual interchange + fixed markup (e.g., interchange + 0.25% + $0.10) |
| Transparency | Simple but opaque — you can’t see interchange | Low — processors control which tier a transaction falls into | High — you see exactly what interchange costs and what the processor charges |
| Best for | Very small businesses with low volume | Rarely the best option — favors the processor | Most businesses processing $10K+/month |
| Cost at $50K/month | ~$1,450–$1,650 | ~$1,300–$1,800 (unpredictable) | ~$1,050–$1,250 |
Most business owners never read their processing statements. These documents show exactly what you’re paying in interchange, assessments, and markup — and they often reveal hidden fees like PCI non-compliance charges, batch fees, and statement fees that can be negotiated or eliminated.
Interchange and assessment fees are non-negotiable, but the processor’s markup is entirely negotiable. If you’re on interchange-plus pricing, focus on getting the markup percentage and per-transaction fee as low as possible. Processors compete aggressively on markup — use competing quotes as leverage.
Card-not-present transactions (online, phone orders) carry higher interchange rates because of increased fraud risk. Using Address Verification Service (AVS) and requiring the CVV code can qualify your transactions for lower interchange categories, saving 0.2%–0.5% per transaction.
Settling your batch within 24 hours of authorization keeps your transactions in the lowest interchange category. Waiting longer can cause transactions to “downgrade” to higher-cost tiers, adding 0.5%–1.0% per transaction.
Manually keyed transactions cost significantly more than chip-read or contactless transactions. The interchange rate for a keyed Visa credit card can be 0.5%–1.0% higher than a chip-read transaction. If you frequently key in card numbers, investing in a mobile card reader pays for itself quickly.
If you’re currently on flat-rate or tiered pricing and processing over $10K/month, switching to interchange-plus is one of the single biggest cost reductions you can make. You’ll see exactly what interchange costs and only pay a thin, transparent markup on top.
The most effective strategy for eliminating processing fees entirely is dual pricing. By displaying both a cash price and a card price, you pass the cost of card acceptance to customers who choose to pay by card — while offering a discount to cash-paying customers. This is legal in all 50 states and lets you retain 100% of every sale.
Dual pricing is fundamentally different from the other strategies above because it doesn’t just reduce fees — it eliminates them. Instead of absorbing 2–4% on every card transaction, you display a cash price (your true price) and a card price (cash price + processing cost). The customer decides how to pay.
This approach has grown rapidly since 2020, driven by rising interchange rates and broader merchant awareness. It’s especially popular in industries with thin margins: restaurants, home services, automotive repair, and retail.
