Visa and Mastercard Interchange Rates
Explained: And How to Pay Less
Credit card processing rates, the interchange fees, assessments, and markups you pay every time you accept a card, are the single largest cost most merchants never examine. This is the complete guide.
What Are Credit Card Processing Rates?
Every time your business accepts a credit or debit card, a transfer fee is paid to the bank that issued the customer’s card. This fee is called the interchange reimbursement fee, and it is set unilaterally by Visa and Mastercard, updated twice per year (April and October), and is completely non-negotiable.
Interchange fees are calculated as a percentage of the transaction amount plus a fixed per-transaction fee. For example, Visa’s CPS/Retail rate for a standard credit card is 1.51% + $0.10. On a $500 transaction, that’s $7.65, just in interchange, before any other fees are added.
Here’s what most merchants don’t understand: interchange is not one rate. Visa publishes over 300 different interchange categories. Mastercard publishes hundreds more. The rate you pay depends on three factors: the type of card used (rewards, corporate, debit), your merchant category code (retail, restaurant, ecommerce), and whether the card was physically present or keyed in.
When people talk about “credit card processing rates,” they’re usually referring to these interchange fees, the wholesale cost that makes up the bulk of what you pay. Understanding interchange is the first step to understanding what’s really happening on your merchant statement.

Where Your Processing Fees Actually Go
Your total credit card processing rate, the “merchant discount rate” on your statement, is made up of three components. Interchange is by far the largest.
Here’s the problem: merchants focus on the 2% discount rate because that’s the number their processor negotiates. But the discount rate is the smallest piece of the pie. The real money is in the other 98%, interchange that can be managed and reduced, hidden fees that shouldn’t exist, and assessments that are often inflated.
What are these hidden fees? They’re the made-up charges buried on pages 3 through 10 of your statement, fees with names like “Network & Processor Access Fee,” “Interchange Clearing Fee,” “Risk Assessment Fee,” “Regulatory Compliance Fee,” and dozens of others. Some are legitimate pass-through costs. Many are completely fabricated by your processor. Without a forensic audit comparing each line item against actual Visa and Mastercard published rates, there’s no way to tell the difference. We find that these hidden fees typically account for 21% of a merchant’s total processing cost, and they are 100% removable.
Credit Card Processing Is an Unregulated Industry
Most business owners assume there’s a government body overseeing what credit card processors charge. There isn’t. The processing industry operates with virtually no regulatory oversight, which means processors can (and do) create fees from thin air.
Senator Durbin’s words were spoken in 2011. Over a decade later, nothing has changed. Two of the world’s largest processors recently settled for $52 million over allegations of over-inflating interchange. The average markup we find in our audits? 0.65% above actual interchange, hidden in plain sight on your statement.
This means you can have the lowest discount rate your processor offers, your transactions can clear at the lowest interchange fees available, and you can still have one of the worst deals in the industry. Because the discount rate is only 12% of the story. The other 88% is where the real money is being taken.
How You Can Have the Lowest Rate and the Worst Deal
Credit card processors know that merchants look at two things: (1) discount rates and (2) transaction fees. So they make those numbers look great, while padding everything else.
An average merchant statement runs four to ten pages per location and contains dozens of fees, more importantly, dozens of unregulated fees. These unregulated fees mean everything in the merchant processing world.
Here’s how the trap works: Your processor gives you a discount rate of 0.05%. Looks fantastic, right? But behind the scenes, they’re inflating the interchange they pass through by 0.65%. So your real discount rate is 0.70%, and you’d never know it by looking at the rate they quoted you.
Then come the fees with names you’ve never heard of: “Network & Processor Access Fee,” “Interchange Clearing Fee,” “Risk Assessment Fee.” Some are legitimate. Many are completely fabricated. Without a forensic audit, it’s impossible to tell the difference.
Why the Card Type Determines Your Processing Rate
Rewards cards, the ones customers love, cost you more. A Visa Infinite card carries an interchange rate of 2.30% + $0.10 at retail, compared to 1.51% + $0.10 for a standard card. That’s a 52% difference on the same transaction. The banks fund those airline miles and cash back rewards with your money.
Debit cards are divided into two categories: Regulated (issued by banks with $10B+ in assets, capped at 0.05% + $0.21 by the Durbin Amendment) and Exempt (issued by smaller banks, with higher rates like 0.80% + $0.15 at retail). The card-issuing bank’s asset size determines which rate applies.
Why B2B Transactions Cost You More, And How to Fix It
If your business accepts corporate purchasing cards, you’re likely paying 25–40% more in interchange than you need to. Business-to-business transactions are automatically downgraded to the highest rate categories unless you submit enhanced data, known as Level II and Level III processing.
Level I (standard) sends only the transaction amount and date. Level II adds tax amount, customer code, and merchant postal code. Level III adds full line-item detail, SKUs, descriptions, quantities, unit prices. Each level of data you send qualifies you for lower interchange rates.
Starting April 2026, Visa is sunsetting the Level II program entirely in favor of its new Commercial Enhanced Data Program (CEDP). Merchants who don’t upgrade to Level III-quality data will see their B2B rates increase significantly.
The difference between a Standard (non-qualified) corporate card rate of 3.15% + $0.10 and a Level III rate of 1.75% + $0.10 is massive. On $1 million in B2B volume, that’s $14,000 in annual savings, just by sending better data.
Common Causes of Interchange Downgrades
A “downgrade” happens when a transaction fails to meet qualification criteria and gets bumped to a higher-cost interchange category. Here are the most common triggers:
Each downgrade can add 0.50% to 1.50% to the interchange rate on that transaction. Over a year, downgrades on just 10% of your volume can cost tens of thousands of dollars.

Quoted Rate vs. Actual Cost: A Real Example
Here’s a real-world breakdown of what a mid-size retailer processing $100,000 per month was quoted versus what they were actually being charged, before we audited their statement.
| Fee Category | What They Were Quoted | What They Were Charged |
|---|---|---|
| Interchange (pass-through) | $1,800 (1.80%) | $2,070 (2.07%) |
| Dues & Assessments | $130 (0.13%) | $210 (0.21%) |
| Processor Markup (Discount Rate) | $100 (0.10%) | $100 (0.10%) |
| Hidden / Junk Fees | $0 | $870 |
| Total Monthly Cost | $2,030 (2.03%) | $3,250 (3.25%) |
The processor honored their quoted discount rate of 0.10%. That part was accurate. Everything else was inflated. Interchange was padded by $270/month. Assessments were inflated by $80/month. And $870/month in hidden fees appeared nowhere in the original agreement. Total overbilling: $1,220 per month, $14,640 per year.
This is not an outlier. This is the average. We find this pattern on 99% of all the audits we perform.
What Each Swipe Really Costs You
Every other guide tells you processing costs “1.5% to 3.5% per transaction.” Here’s what that looks like in real dollars, and what it actually looks like after hidden fees.
| Transaction Size | Quoted Fee (2.5%) | Actual Fee (3.8%) | You’re Losing |
|---|---|---|---|
| $25 (coffee shop) | $0.63 | $0.95 | $0.33 per swipe |
| $75 (retail sale) | $1.88 | $2.85 | $0.98 per swipe |
| $250 (restaurant tab) | $6.25 | $9.50 | $3.25 per swipe |
| $1,000 (service invoice) | $25.00 | $38.00 | $13.00 per swipe |
| $5,000 (B2B order) | $125.00 | $190.00 | $65.00 per swipe |
| $25,000 (large B2B) | $625.00 | $950.00 | $325.00 per swipe |
Multiply these numbers by the hundreds or thousands of transactions you process each month. For a B2B company processing 200 transactions at an average of $2,500, the overpayment is $6,500 per month, $78,000 per year, going straight from your bank account to your processor’s bottom line.
Why Your Processing Cost Is So High
Credit card processing is the single largest unregulated cost most businesses pay. There is no government agency that audits processor billing. There are no consumer protection laws that require processors to charge the actual interchange rate. There is no law preventing a processor from inventing a fee and putting it on your statement.
Here’s why that matters: You give your processor unrestricted ACH access to your business bank account. Every month, they withdraw whatever they want. Most merchants assume these withdrawals are regulated, that someone, somewhere, is making sure the numbers are right. Nobody is.
The result is an industry built on information asymmetry. There are over 1,000 interchange rate categories across Visa and Mastercard combined. The rate schedules are updated every April and October. Processors use this complexity as cover, inflating a fee by a few basis points here, adding a new line item there, knowing that the overwhelming majority of merchants will never check.
Multiple class-action lawsuits have been filed against major processors for inflating interchange fees. In several cases, processors settled for tens of millions of dollars, and then stated publicly that they would continue conducting business the same way. That should tell you everything you need to know.

How to Actually Reduce Your Processing Cost
Most advice on reducing processing costs focuses on negotiating your discount rate. This is the equivalent of arguing about the price of the cup while ignoring the ocean it’s floating in. Your discount rate is 2% of your total processing cost. The other 98% is where the money is.
Here’s what actually works:
1. Get a forensic audit. Not a “free analysis” from a competing processor who wants to switch you. A line-by-line forensic comparison of every charge on your statement against official Visa and Mastercard published rate schedules. This is the only way to identify inflated interchange, hidden fees, and fabricated charges.
2. Optimize your interchange. Many transactions settle at higher interchange rates than necessary because of missing data fields, incorrect MCC codes, or improper transaction routing. For B2B merchants, the difference between Level I and Level III data can reduce interchange by 0.70% to 1.00%, on every transaction.
3. Remove hidden fees. Once identified, hidden and fabricated fees can be eliminated. This typically represents the single largest cost reduction, 21% of total processing cost on average.
4. Monitor monthly. Processors add new fees over time. Interchange rates change every April and October. Without ongoing monitoring, the overbilling comes back. We perform monthly audits to ensure the savings stick.
You don’t have to switch processors. You don’t have to change anything about how you accept payments. You just need someone to verify that every dollar your processor takes out of your bank account is legitimate.
