The Biggest Fee on Every Card Sale (Interchange)
- What you actually pay, blended: about 0.89% + $0.158 card-present and 1.36% + $0.152 online on a typical US card mix. That's the site's own derived blend, and the arithmetic is published
- What one card costs: anywhere from 0.05% + $0.21 on regulated debit to 3.15% + $0.10 on a non-qualified penalty rate. Two different questions, two different numbers
- No US merchant's blend starts at 1.5%. Debit is 63% of US card transactions by count. Most of it's federally capped at about 24 cents on a $46 sale. Any page quoting "1.5% to 3.5%" is quoting the credit sub-range and dropping most of your transactions
- You can't negotiate interchange directly, but you can influence which rate applies: card type, data quality (Level 2/3), authorization method, and settlement timing all affect your rate
- A rewards or commercial card costs 1 to 3 points more than a regulated debit card on the same sale. On a $50 sale that's about $0.24 versus about $1.60. Your customer picks which one you get
- Interchange downgrades are the most common source of overpayment. That's when you're charged a higher rate than you expected. Look for "non-qualified" or "downgraded" line items on your statement
Interchange is the fee your bank pays the cardholder's bank every time someone pays you by card. It's the largest component of card processing costs. Card networks set it, and acquirers pay it to issuers. It gets passed through to you on your bill. You can't negotiate interchange directly, but you can influence which rates apply.
Know how interchange works and you'll spot where you're overpaying. You'll also see what you actually control.
What Is Interchange?
Interchange is a fee your bank pays the cardholder's bank. That's the acquirer paying the issuer, on every card transaction. It compensates issuers for:
- Float: Issuer pays merchant before collecting from cardholder
- Credit risk: Cardholder might not pay their bill
- Fraud risk: Unauthorized transactions
- Rewards programs: Cash back, miles, points
- Operating costs: Card issuance, customer service, fraud monitoring
Who Sets Interchange?
Card networks (Visa, Mastercard, etc.) publish interchange schedules. Individual issuers don't negotiate rates. The network sets categories based on:
- Card type (debit, credit, rewards, commercial)
- Merchant category (MCC)
- Transaction type (card-present vs card-not-present)
- Data quality (AVS, CVV, Level 2/3)
- Processing method (chip, swipe, keyed)
Your Total Processing Cost
Total Cost = Interchange + Assessments + Processor Markup
| Component | Typical cost | Who Sets It | Negotiable? |
|---|---|---|---|
| Interchange | 0.89% + $0.158 in person, 1.36% + $0.152 online (blended) | Networks | No |
| Assessments | Not published. Assumed 0.14% + $0.02 | Networks | No |
| Processor markup | 0.1-0.5%+ | Processor | Yes |
That interchange row is a blend covering a normal US card mix, not any one card's rate. It's built off Visa's US schedule of 18 April 2026 and Mastercard's of 17 April 2026, with Federal Reserve transaction counts setting the weights. Change a weight in the full derivation and rerun it.
Interchange is the biggest single line, but it isn't 90% of your bill. Take a $50 card-present ticket on interchange-plus pricing and it's about 62% of what you pay: $0.60 interchange, $0.09 assessments, $0.28 markup. On flat-rate pricing the share is lower because your processor keeps more of the spread. Optimize here first anyway, since it's the biggest line.
Interchange Rate Categories
By Card Type
This is the spread that "interchange is 1.5% to 3.5%" was reaching for, and the real one is much wider than that. US domestic only, Visa and Mastercard only.
| Card Type | Card-present | Online | Why |
|---|---|---|---|
| Regulated debit | 0.05% + $0.21 | 0.05% + $0.21 | A federal cap, not a network price. Identical on both networks |
| Exempt debit | 0.70-0.80% + $0.15 | 1.65% + $0.15 | Issuers under $10 billion in assets aren't capped |
| Credit, no rewards | 1.51% + $0.10 | 1.89% + $0.10 | The floor for consumer credit |
| Credit, rewards | 1.65-2.10% + $0.10 | 2.05-2.50% + $0.10 | Rewards get funded out of interchange |
| Credit, premium | 2.30% + $0.10 | 2.60% + $0.10 | Visa Infinite and Mastercard World Elite. Both networks publish the same number |
| Small business | around 2.10% + $0.10 | 2.79% + $0.10 | Visa Business Product 2 and its Mastercard equivalents |
| Commercial, corporate, purchasing | 2.50-3.00% + $0.10 | 2.50-3.00% + $0.10 | The B2B band. Level 2/3 data is worth real money here |
| Non-qualified | 3.15% + $0.10 | 3.15% + $0.10 | A penalty for failing qualification. Not a price to budget for |

Four caveats.
- The regulated debit line is $0.21, plus a penny. Regulation II sets it at $0.21 + 0.05% of the sale. Add a $0.01 fraud-prevention adjustment for issuers that certify. Not every issuer does. That's why you'll see $0.21 and $0.22 quoted for the same thing.
- Small-business cards aren't commercial cards. Visa's small-business Product 2 tier sits around 2.10% card-present. That's well below the corporate and purchasing band. Don't budget one at the other's rate.
- 3.15% is a punishment, not a price. It's what you pay when a transaction fails qualification. Treating it as the top of a normal range is how "up to 3.5%" gets into circulation.
- There's no International row here, and the 1.80-2.40% you'll find elsewhere isn't sourced from these schedules. US domestic tables don't cover cross-border interchange at all. That lives in Visa's separate interregional guide, so any cross-border figure quoted alongside domestic ones has come from somewhere else.
3.5% appears nowhere in either network's published US schedule. Above 3.00%, Visa tops out at 3.15% + $0.10 and Mastercard at 3.30% + $0.10, on small business Standard at Level 5. Nothing either network publishes reaches 3.5%.
3.5% is a processor's keyed-entry price. Clover publishes 3.5% + 10c keyed and Square publishes 3.5% + 15c keyed, so somebody copied a merchant discount rate into an interchange table and it spread from there. It's a fast test for whether a fee-comparison page did any primary research.
Which number is yours
Card type is the dominant variable. Most fee articles hide it. Find yourself here:
| If your volume is mostly | Read this as your interchange | Because |
|---|---|---|
| Debit, retail, small tickets | Well under 1% | Regulated debit is 24 cents on a $46 sale, whatever the percentage says |
| Consumer credit, in person | 1.51% to 2.30% + $0.10 | This is the range "1.5% to 2.5%" was actually describing |
| Consumer credit, online | 1.89% to 2.60% + $0.10 | Online runs 0.4 to 0.5 points above card-present on the same card |
| B2B, commercial and purchasing cards | 2.50% to 3.00% + $0.10 | And Level 2/3 data is worth real money to you. See below |
| A normal mix of all of it | 0.89% + $0.158 in person, 1.36% + $0.152 online | That's the blend, and it's the number most SMBs should budget on |
The same $50 sale costs about $0.24 on regulated debit and about $1.60 on a commercial card, so a debit-heavy coffee shop doesn't pay what a B2B supplier pays. No single number describes both.
By Transaction Type
| Transaction Type | Rate Impact | Why |
|---|---|---|
| Card-present (chip) | Lowest | Most secure |
| Card-present (contactless) | Low | Secure, fast |
| Card-present (swipe) | Medium | Less secure than chip |
| Card-not-present | Highest | Highest fraud risk |
| Keyed/manual | Highest | No card verification |
By Merchant Category (MCC)
| Category | Typical Rate | Why |
|---|---|---|
| Grocery | Lower | Thin margins, high volume |
| Gas stations | Lower | Competitive market |
| Utilities | Lower | Essential services |
| Retail | Medium | Standard risk |
| Restaurants | Medium | Standard risk |
| E-commerce | Higher | Higher fraud |
| High-risk MCCs | Highest | Elevated fraud/chargebacks |
Interchange Qualification
Transactions "qualify" for different interchange tiers based on how they're processed, and missing the requirements means higher rates. This is the cheapest money on the page. AVS, CVV and a same-day batch cost you nothing, and they close three of the five downgrade causes below.
Qualification Levels
| Level | Rate | Requirements |
|---|---|---|
| Qualified | Lowest | All requirements met |
| Mid-qualified | Medium | Most requirements met |
| Non-qualified | Highest | Requirements not met |
What Causes Downgrades
| Issue | Downgrade Impact | Fix |
|---|---|---|
| Missing AVS data | +0.3-0.5% | Always submit address |
| Missing CVV | +0.2-0.4% | Always collect CVV |
| Late settlement | +0.3-0.5% | Batch same day |
| Wrong transaction type | Varies | Use correct codes |
| Missing Level 2/3 data | +0.75% on commercial cards | Submit enhanced data |
Qualification Checklist
For every transaction:
- Submit billing address for AVS
- Submit CVV for CNP transactions
- Batch within 24 hours of authorization
- Use correct transaction type indicators
- Include tax amount (for Level 2)
Level 2 and Level 3 Processing
Enhanced data levels reduce interchange on B2B transactions.
Level 2 Data
Required fields:
- Tax amount
- Customer code/PO number
- Merchant postal code
Savings: 0.75 points on a small business credit card. Mastercard prices Data Rate I at 2.65% + $0.10 and Data Rate II at 1.90% + $0.10. Visa's Business Product 1 and 2 match it exactly. The gap holds at every card tier. Full tables
Level 3 Data
All Level 2 plus:
- Line item details (description, quantity, unit cost)
- Product codes
- Freight/shipping amounts
- Duty amounts
Savings: 0.80 to 0.95 points vs Level 1, on corporate and purchasing cards only. Visa moves those from 2.70% to 1.75%. Small business credit has no Level 3 rate at either network
Who Benefits from Level 2/3?
| Business Type | Level 2/3 Value |
|---|---|
| B2B sellers | High (commercial cards common) |
| Government vendors | High (purchasing cards) |
| Wholesalers | High |
| Consumer retail | Low (few commercial cards) |
| Consumer e-commerce | Low |
Implementation
Most processors support Level 2/3 data. Check:
- Does your processor accept Level 2/3?
- Can your POS/gateway transmit the fields?
- What % of your transactions are commercial cards?
ROI calculation:
Annual B2B volume × Commercial card % × 0.5% savings = Annual savings
Example: $1M × 40% × 0.5% = $2,000/year
Interchange Optimization Strategies
1. Encourage Debit
Regulated debit costs 0.05% + $0.21. Consumer credit runs 1.51% to 2.30% + $0.10 in person, and 1.89% to 2.60% + $0.10 online.
| $100 card-present sale | Rate | Interchange | Versus regulated debit |
|---|---|---|---|
| Regulated debit | 0.05% + $0.21 | $0.26 | - |
| Exempt debit | 0.80% + $0.15 | $0.95 | +$0.69 |
| Rewards credit | 1.65% + $0.10 | $1.75 | +$1.49 |
| Premium credit | 2.30% + $0.10 | $2.40 | +$2.14 |
Tactics:
- PIN debit option at checkout
- Debit-first button order
- Cash discount programs
2. Reduce Card-Not-Present Rates
CNP transactions pay higher interchange, so convert to card-present wherever the business allows it:
| Channel | Rate Premium |
|---|---|
| Card-present chip | Baseline |
| Card-not-present | +0.3-0.5% |
| Keyed entry | +0.5-1.0% |
Tactics:
- In-store pickup with card-present payment
- Mobile POS for service businesses
- Payment terminals for recurring (where compliant)
3. Qualify All Transactions
Ensure no unnecessary downgrades:
- Always submit AVS/CVV
- Batch daily (not weekly)
- Use correct MCC
- Include tax amounts
4. Implement Level 2/3 for B2B
If more than 20% of volume is commercial cards:
- Enable Level 2 data (low effort)
- Consider Level 3 for large B2B volume
5. Review Card Mix
Understand your card mix:
| Card Type | % of transactions (example) | Card-present rate |
|---|---|---|
| Regulated debit | 25% | 0.05% + $0.21 |
| Exempt debit | 15% | 0.80% + $0.15 |
| Credit, no rewards | 5% | 1.51% + $0.10 |
| Rewards credit | 40% | 1.65% + $0.10 |
| Premium credit | 10% | 2.30% + $0.10 |
| Commercial | 5% | 2.50% + $0.10 |
Weight by transaction count, not by dollars. Weighting by dollar value over-weights credit, which carries bigger tickets, and it mishandles the fixed cent component, because a $0.21 debit fee is charged per transaction, not per dollar.
A rewards-heavy or commercial-heavy mix costs you more, and you mostly can't shift it. Your customer picks the card, so budget on the mix you actually have rather than the one you'd prefer.
Interchange-Plus Pricing
What It Is
Processor passes through exact interchange + adds fixed markup.
Your cost = Interchange (varies by card) + Markup (fixed)
Example, card-present blend: 0.89% + $0.158 interchange + 0.40% + $0.08 markup
= 1.29% + $0.238
Why It's Better
| Pricing Model | Transparency | Best For |
|---|---|---|
| Interchange-plus | Full | Most merchants |
| Tiered/bundled | Low | Processor (not you) |
| Flat rate | Simple | Very small volume |
Interchange-plus is what makes the markup visible, and a visible markup is the only kind you can negotiate. At very small volume the simplicity of a flat rate is worth the spread. Tiered isn't a third option. It's the one to walk away from.
What to Ask Your Processor
- "Can you show me exact interchange on my statement?"
- "What is your markup over interchange?"
- "Are there any other fees beyond interchange + markup?"
Reading Your Interchange Statement
What to Look For
| Line Item | What It Means |
|---|---|
| VS CPS RETAIL DEBIT | Visa card-present retail debit rate |
| VS CPS E-COMMERCE | Visa card-not-present rate |
| MC MERIT III | Mastercard high-qualification rate |
| EIRF | Electronic interchange reimbursement fee (downgraded) |
| Standard | Non-qualified rate (worst) |
Red Flags
- High percentage of "Standard" or "EIRF" transactions
- Downgrades you can't explain
- Interchange categories you don't recognize
Monthly Interchange Audit
- Pull interchange breakdown from processor
- Calculate average rate by card type
- Identify highest-cost categories
- Check for unexpected downgrades
- Calculate effective rate (total fees / total volume)
Network-Specific Notes
Visa
- Publishes rates semi-annually (April, October)
- CPS (Custom Payment Service) rates for qualified transactions
- EIRF (Electronic Interchange Reimbursement Fee) for downgrades
Mastercard
- Publishes rates semi-annually
- Merit rates for qualified transactions
- Standard rates for non-qualified
American Express
- Different model (often direct acquiring)
- Rates not publicly published
- OptBlue program for third-party acquiring
- Generally higher than Visa/MC
Discover
- Similar structure to Visa/MC
- Smaller market share
- Competitive rates to gain acceptance
Interchange by Country
The interchange rates on this page are US rates. Interchange varies significantly by country and region.
Key Differences
| Region | Consumer Credit Cap | Consumer Debit Cap | Who Sets It |
|---|---|---|---|
| United States | No cap. Published 1.51-3.15% + $0.10 by card type; typical blend under 1.5% | Durbin: 0.05% + $0.21 (regulated banks) | Card networks (Visa, MC) |
| Canada | No cap (market rates: ~1.4-2.0%) | Interac in-store: ~$0.05-0.10 flat; Visa/MC debit: market rates | Card networks + Interac |
| European Union | Capped at 0.30% | Capped at 0.20% | EU Interchange Fee Regulation (2015) |
| United Kingdom | Capped at 0.30% (domestic) | Capped at 0.20% (domestic) | Retained EU law (PSR enforces) |
| Australia | Capped at 0.50% (weighted avg) | Varies | Reserve Bank of Australia |
Why This Matters
- EU merchants pay much less interchange than US merchants. A US merchant pays 1.65% on a consumer rewards credit card. In the EU the same card type is 0.30%.
- Canadian merchants get Interac debit at flat per-transaction fees in store. Credit card interchange is close to US levels. Visa Debit and Mastercard Debit in Canada follow market rates. Those are similar to US rates.
- Cross-border transactions ignore domestic caps. A US merchant selling to an EU customer pays US interchange. Or worse, cross-border rates.
- Seen "1.2% processing" advertised by a global processor? Check whether that's a domestic EU rate. It won't apply to US transactions.

Scale Callout
| Volume | Focus |
|---|---|
| Under $100k/mo | Use flat-rate processor. Don't overthink interchange. |
| $100k-$500k/mo | Switch to interchange-plus. Review monthly. |
| $500k-$2M/mo | Optimize qualification. Consider Level 2. Negotiate markup. |
| Over $2M/mo | Full interchange analysis. Level 2/3. Payment consultant may help. |
Where This Breaks
-
Chasing debit when customers want credit. Forcing debit can hurt conversion, and a lost sale costs far more than the $1.49 you'd have saved on a $100 rewards-card ticket. Nudge, don't block.
-
Over-optimizing small volume. Spending 10 hours to save $50/month isn't worth it. Focus effort where volume justifies it.
-
Processor games. Some processors quote low interchange but add hidden fees elsewhere, so compare total effective rate, not just interchange.
