What Is Interchange-Plus Pricing? (And Why It's Better Than Flat Rate)

Most merchants are on flat-rate pricing without knowing what interchange-plus is or how much more they could save. Here is a complete explanation of how interchange-plus pricing works and when it makes sense to switch.

What Is Interchange-Plus Pricing? (And Why It's Better Than Flat Rate)

Executive Underwriting Summary

Interchange-plus pricing passes actual Visa/Mastercard interchange costs through to the merchant, plus a transparent processor margin. For most businesses processing over $10,000/month, it is significantly cheaper than flat-rate pricing.

What Is Interchange?

Before understanding interchange-plus pricing, you need to understand interchange itself.

Every time a customer pays with a credit or debit card, the transaction involves three parties in addition to you and your customer:

  1. Your bank (acquiring bank): The bank that holds your merchant account
  2. The card network (Visa or Mastercard): Routes the transaction between banks
  3. The customer's bank (issuing bank): The bank that issued the customer's card

Interchange is the fee that the issuing bank charges for authorizing the transaction. When your customer pays you $100 with their Visa credit card, the issuing bank takes an interchange fee — typically 1.5%-2.5% — from that $100 before the money reaches you.

Interchange rates are set by Visa and Mastercard, not by your payment processor. They are published publicly and updated twice per year (in April and October). There are over 400 distinct interchange categories in Visa's US fee schedule alone.


How Interchange Rates Vary

Interchange rates vary based on several factors:

| Factor | Lower Rate | Higher Rate | |---|---|---| | Card type | Basic Visa debit | Visa Infinite or Signature rewards | | Transaction method | In-store chip card | Card-not-present (online) | | Industry (MCC) | Healthcare, utilities | Travel, digital goods | | Transaction amount | Small ticket | High ticket (certain categories) | | Authentication | 3DS2 authenticated | No 3DS |

Example interchange rates (2026 US published rates):

  • Regulated debit card (in-store): 0.05% + $0.21
  • Standard Visa credit (in-store): 1.51% + $0.10
  • Visa Signature rewards (in-store): 2.10% + $0.10
  • Standard Visa credit (card-not-present): 1.80% + $0.10
  • Visa business card (card-not-present): 2.65% + $0.10

The Two Main Pricing Models

Flat-Rate Pricing (Stripe Model)

Flat-rate pricing charges you a single, uniform rate on every transaction regardless of the actual interchange cost.

Example: Stripe standard pricing

  • 2.9% + $0.30 per online transaction
  • This rate applies whether your customer used a basic debit card (actual interchange: 0.05% + $0.21) or a premium Visa Infinite rewards card (actual interchange: 2.40%)

When a customer pays with a basic debit card on Stripe, you pay 2.9% + $0.30. Stripe pays the issuing bank 0.05% + $0.21. Stripe keeps the approximately 2.85% difference. On a $100 debit card transaction, Stripe earns $2.86 in margin on that single transaction.

When a customer pays with a premium rewards card, Stripe's margin drops to approximately 0.50%.

Stripe profits heavily on debit and basic credit card transactions and makes lower margins on premium cards. The flat rate averages out — to Stripe's advantage.

Interchange-Plus Pricing

Interchange-plus pricing passes through the actual interchange cost of each transaction, plus a fixed processor margin.

Example: Interchange-plus at 0.30% + $0.15

  • Basic Visa debit: 0.05% + $0.21 interchange + 0.30% + $0.15 = approximately 0.35% + $0.36 total
  • Premium Visa Infinite: 2.40% interchange + 0.30% + $0.15 = approximately 2.70% + $0.15 total

With interchange-plus, you pay the actual cost of each transaction plus a transparent, fixed processor margin. When your customers use debit cards or basic credit cards, you pay significantly less than flat rate.


The Math: How Much More You Pay on Flat Rate

For a typical e-commerce merchant with a mixed card type distribution, the blended interchange rate averages approximately 1.6%-1.8%. Compare this to flat-rate pricing:

| Card Mix | Actual Blended Interchange | Flat Rate (Stripe) | Effective Overpayment | |---|---|---|---| | 40% debit, 60% basic credit | ~1.3% blended | 2.9% + $0.30 | ~1.6% overpayment | | 20% debit, 80% mixed credit | ~1.7% blended | 2.9% + $0.30 | ~1.2% overpayment | | 10% debit, 90% premium credit | ~2.2% blended | 2.9% + $0.30 | ~0.7% overpayment |

Dollar impact at different processing volumes:

| Monthly Volume | 1.2% Overpayment/Month | Annual Cost of Flat Rate | |---|---|---| | $25,000 | $300/month | $3,600/year | | $50,000 | $600/month | $7,200/year | | $100,000 | $1,200/month | $14,400/year | | $250,000 | $3,000/month | $36,000/year | | $500,000 | $6,000/month | $72,000/year |


When Does Interchange-Plus Make Sense?

Interchange-plus pricing has a higher baseline complexity (statements show many line items instead of one rate) but is financially superior for almost every merchant processing over $10,000/month.

Interchange-plus is clearly the better choice when:

  • You process over $10,000/month
  • Your average ticket is over $25
  • Your customer base tends to use business credit cards, rewards cards, or premium cards
  • You want complete transparency into your processing costs
  • You are comparing multiple processors and need to evaluate apples-to-apples

Flat-rate pricing may be acceptable when:

  • You process under $5,000/month (administrative simplicity may outweigh cost savings)
  • You have very low transaction count where per-transaction fees dominate over percentage
  • You need an extremely simple, single-rate billing experience for accounting purposes

How to Read an Interchange-Plus Statement

An interchange-plus statement is more complex than a flat-rate statement because each transaction is grouped by interchange category. Here is what you will see:

Interchange categories: Visa and Mastercard have hundreds of interchange categories. Your statement groups transactions by category and shows the interchange rate applied to each.

Processor markup: A separate line showing your processor's fixed margin (e.g., 0.30% + $0.15) applied to total volume.

Assessment fees: Visa and Mastercard charge their own small fees (typically 0.13%-0.14% for Visa; 0.13% for Mastercard) on top of interchange. These pass through in interchange-plus pricing.

Network fees: NABU fee (Visa Network Access Brand Usage), Mastercard Network and Brand Usage fee — typically $0.0195 per transaction.

Monthly fees: Statement fee, gateway fee, or minimum monthly fee appear as separate line items.

The total of interchange + processor markup + assessment fees + network fees + monthly fees is your all-in cost.


Interchange-Plus for High-Risk Merchants

High-risk merchants have historically been sold on opaque pricing structures because high-risk processors have less pricing competition than standard processors. This is changing.

At Gray Merchants, every placed merchant account uses interchange-plus pricing. Your statement shows:

  • Exact interchange costs by category
  • Our fixed processor margin (disclosed upfront, in your merchant agreement)
  • All network and assessment fees passed through at cost
  • No hidden fees or bundled margins

This matters particularly for high-risk merchants because your interchange costs may be lower than you think. Many high-risk businesses (subscription companies, coaching businesses, professional services) have high debit card usage, which carries very low interchange. With flat-rate pricing, you are paying 2.9% on transactions that actually cost 0.35% in interchange.


Comparing Processor Quotes: The Right Approach

When you receive quotes from multiple processors, comparing rates requires understanding what pricing model each uses:

If comparing flat rates: Simply compare the percentage and per-transaction fee. Lower is better.

If comparing interchange-plus: Compare the processor markup (the 'plus' part), not the interchange (which is fixed by card networks for everyone). A processor quoting 'interchange + 0.20% + $0.10' is generally better than one quoting 'interchange + 0.40% + $0.15.'

Beware of tiered pricing: Some processors present three tiers (qualified, mid-qualified, non-qualified). This is effectively a bundled rate structure that appears simpler than it is. Most transactions fall into mid- or non-qualified tiers, where the rates are significantly higher. Tiered pricing is almost always more expensive than interchange-plus.


Frequently Asked Questions

What is the processor markup at Gray Merchants? Our processor markup is disclosed in your merchant agreement before you sign. We do not quote markup in public materials because it varies by industry and risk profile — but it is competitive with the best interchange-plus pricing in the high-risk market.

Can I switch from flat-rate to interchange-plus without changing my gateway? In most cases, yes. Switching pricing models is a merchant agreement change, not a gateway change. Your existing Authorize.net or NMI integration typically remains unchanged when you switch processors.

Are there any transactions where flat-rate pricing is cheaper than interchange-plus? Yes — transactions on premium rewards cards with very high interchange rates (above 2.7%) would occasionally make flat-rate pricing cheaper. However, these represent a small fraction of typical transaction volume. The vast majority of transactions are cheaper under interchange-plus.

How do I know if my current processor is using interchange-plus or tiered pricing? Look at your monthly statement. Interchange-plus statements show dozens of interchange categories with different rates. Tiered pricing statements show 2-3 rates (qualified, mid-qualified, non-qualified) covering all transactions. If you cannot determine this from your statement, ask your processor directly for your 'pricing model' and 'processor markup.'

How Interchange-Plus Works: A Detailed Walkthrough

When a customer uses a Visa Signature Rewards card to purchase $500 from your online store, the interchange fee is approximately 2.10% + $0.10. Your processor's markup is 0.50% + $0.15. Your total cost is 2.60% + $0.25, or $13.25.

Under tiered pricing, the same transaction might be classified as "non-qualified" (rewards cards are often tiered as non-qual) and charged at a flat 3.5%. That's $17.50 -- $4.25 more than interchange-plus for the identical transaction.

This difference compounds at scale. At $500,000/month, the same differential ($4.25 per $500 average order = 0.85%) adds up to $4,250 per month, or $51,000 per year.


Interchange Categories: How Visa and Mastercard Classify Transactions

Visa and Mastercard each maintain interchange tables with dozens of categories. The key variables that determine which rate applies:

Card type:

  • Debit cards: Lower interchange than credit (regulated debit is 0.05% + $0.21 flat)
  • Standard credit: Base interchange rates (e.g., Visa CPS Retail: 1.51% + $0.10)
  • Rewards credit: Higher interchange to fund rewards programs (1.65%--2.30% + $0.10)
  • Corporate/purchasing cards: Varies widely (1.75%--2.95%)
  • Premium rewards (Signature Preferred, World Elite): Highest interchange (2.10%--2.70%)

Transaction environment:

  • Card present (swiped/dipped/tapped): Lower rates
  • Card not present (online, phone): Higher rates (card-not-present premium: +0.30%--0.70%)

Merchant category code (MCC):

  • Supermarkets: Special lower interchange rates
  • Travel and entertainment: Higher rates
  • High-risk categories: Standard CNP rates (no special lower rates)

Processing quality:

  • Transactions with full authorization data (AVS, CVV, order number): Lower rates
  • Transactions with incomplete authorization data: Downgrade to higher "non-qualified" rates

The Most Common Interchange Downgrades

Interchange downgrades are the hidden cost many merchants don't understand until they see them on their statements. A downgrade means a transaction was processed in a way that triggers a higher interchange rate than the expected rate.

Downgrade reason 1: Card not swiped (key-entered) Manually entering a card number instead of swiping or dipping triggers card-not-present rates even for in-person transactions. Avoidable by using EMV chip readers.

Downgrade reason 2: Delayed settlement Transactions that are not settled within 24 hours of authorization may downgrade. Settle daily.

Downgrade reason 3: Missing or incomplete AVS data Online transactions that don't send full AVS data (billing address and zip code) may not qualify for the best online CNP rates.

Downgrade reason 4: Corporate card without Level 2 or Level 3 data Corporate purchasing cards have lower interchange when processed with enhanced data (purchase order number, item details). Without this data, they downgrade to standard corporate rates.

Downgrade reason 5: Transaction amount changed after authorization Hospitality merchants who authorize for an estimated amount and settle for a different amount (hotel checkout) may trigger downgrades if the difference exceeds permitted thresholds.


Interchange-Plus vs. Tiered vs. Flat Rate: Full Comparison

| Pricing Model | How It Works | Best For | Worst For | |---|---|---|---| | Interchange-plus | Interchange cost + fixed markup | Most merchants over $10K/month | Very low volume merchants | | Tiered | 3-tier flat rates | Mainstream low-risk retail (when offered by reputable processor) | High-risk, rewards card-heavy business | | Flat rate | One rate for all (e.g., 2.9% + $0.30) | Very low volume, Stripe-type processors | High-volume merchants | | Membership/subscription | Monthly fee + interchange at cost | Very high volume ($1M+/month) | Low volume merchants |

Flat rate vs. interchange-plus for high-risk merchants:

Flat rate processors (Stripe, Square) are not available for most high-risk merchants. Even if they were, flat rate at 2.9% + $0.30 is competitive with interchange-plus only if your effective interchange is near 2.5%. For low-risk card types (debit), interchange-plus is much cheaper.

Why tiered pricing disadvantages high-risk merchants:

High-risk merchants process a higher percentage of premium rewards cards and card-not-present transactions than typical retail. Both of these are classified as "non-qualified" in most tiered structures. A tiered quote of "2.9% qualified" that doesn't mention the 3.75% "non-qualified" rate is hiding the rate that applies to most of your transactions.


Reading Your Processing Statement: Identifying Your Effective Rate

Your processing statement should be reviewed monthly. Key things to find:

Gross processing volume: Total sales for the month.

Total processing fees: Sum of all fees (discount, transaction, monthly, chargeback, gateway).

Effective rate = Total fees / Gross volume. This is the only number that allows comparison between processors.

Interchange cost breakdown (on interchange-plus statements): Your statement should show the interchange category for each transaction type and the corresponding rate. Look for unexpectedly high-cost categories -- these may indicate downgrades you can address.

Chargeback fees: Separate line items per chargeback. If this is growing, your dispute prevention needs attention.

Reserve activity: Rolling reserve contributions and releases should appear as separate line items.

If your statement does not provide this level of detail, request an interchange-level breakdown from your processor. Under interchange-plus, you are entitled to see the underlying cost structure.


Negotiating Your Interchange-Plus Markup

The markup (the processor's revenue above interchange) is the negotiable component of interchange-plus pricing.

Starting markups for high-risk merchants by tier:

  • New merchant (no history): Typically 1.5%--2.5% + $0.10--$0.25
  • Established merchant (12+ months clean): Typically 1.0%--1.75% + $0.10--$0.20
  • High-volume merchant ($500K+/month): Typically 0.5%--1.0% + $0.10--$0.15

Negotiation leverage:

  • Processing history showing clean chargeback ratio below 0.5%
  • Monthly volume over $100,000 (leverage increases significantly at $500K+)
  • Competing offer from another processor (single biggest leverage)
  • Business financial strength (audited financials, strong bank balances)

What to ask for: Request a markup reduction of 0.25%--0.50% at your 12-month review if your chargeback ratio has been below 0.5%. Bring 12 months of statements to the conversation.


Interchange-Plus for High-Risk Industries: Rate Expectations

| Industry | Typical Interchange | Processor Markup | Effective Rate | |---|---|---|---| | Nutraceuticals | 1.65--2.10% (CNP) | 1.5--2.0% | 3.15--4.10% | | CBD / Hemp | 1.65--2.10% (CNP) | 1.75--2.25% | 3.40--4.35% | | Adult content | 1.65--2.10% (CNP) | 2.50--3.50% | 4.15--5.60% | | Online gaming | 1.65--2.10% (CNP) | 2.0--3.0% | 3.65--5.10% | | Online coaching | 1.65--2.10% (CNP) | 1.25--1.75% | 2.90--3.85% | | Firearms (card present) | 1.15--1.65% (CP) | 1.25--1.75% | 2.40--3.40% | | Travel agencies | 1.65--2.10% (CNP) | 1.75--2.5% | 3.40--4.60% |


Geographic Context for Interchange Pricing

US domestic merchants: All processors using Visa and Mastercard US interchange tables pay the same underlying interchange. The only difference is the markup, which is entirely negotiable.

International merchants processing US cards: Cross-border interchange is typically 0.4%--0.8% higher than US domestic interchange. This applies to merchants outside the US accepting US-issued cards.

Debit card interchange: Regulated debit (issued by banks with over $10B in assets) is capped by the Durbin Amendment at $0.21 + 0.05%. Unregulated debit and prepaid cards have interchange similar to credit cards. High-debit-card-percentage businesses benefit significantly from interchange-plus because they capture the low Durbin rate directly.


Frequently Asked Questions

Q: What does interchange-plus pricing mean?

A: Interchange-plus means your processing fee equals the actual interchange cost (set by Visa/Mastercard) plus a fixed markup charged by your processor. Example: interchange + 1.5% + $0.10. This model is transparent because you see exactly what the interchange costs and what the processor earns.

Q: Is interchange-plus always cheaper than flat rate?

A: For most high-volume merchants, yes. Flat rate is convenient but does not reflect the actual cost of debit card transactions (which are much cheaper than flat rate implies). Interchange-plus passes the debit savings through to you.

Q: How do I know if I am on interchange-plus or tiered pricing?

A: Ask your processor directly. Your statement should show "IC+" or "interchange-plus" as the pricing model. If your statement shows "qualified," "mid-qualified," and "non-qualified" categories with no interchange breakdowns, you are on tiered pricing.

Q: What is the standard interchange-plus markup for high-risk merchants?

A: Typical starting markups are 1.5%--2.5% for new high-risk merchants. Established merchants with clean chargeback history negotiate to 1.0%--1.75%. Volume over $500K/month can reach 0.5%--1.0%.

Q: Can I switch from tiered to interchange-plus pricing with my current processor?

A: Some processors allow you to switch pricing models on request. Others require signing a new agreement. If your processor cannot or will not convert you to interchange-plus, that is a reason to evaluate competing offers.

Q: What is a "downgrade" in payment processing?

A: A downgrade means a transaction was processed in a way that triggers a higher interchange category than expected. Common causes: key-entered card numbers, delayed settlement, missing AVS data, corporate cards without enhanced data. Reducing downgrades improves your effective rate without changing your markup.

Q: Does Gray Merchants use interchange-plus pricing?

A: Yes. Every merchant account we place uses interchange-plus pricing with a documented markup. We provide the full rate structure in writing before you sign anything.


Summary: Making the Most of Interchange-Plus Pricing

Interchange-plus pricing is not just about getting the lowest rate -- it is about understanding the true cost of every transaction you process and having the data to optimize intelligently.

Action items:

  1. Confirm you are on interchange-plus pricing (not tiered)
  2. Calculate your effective rate monthly (total fees / gross volume)
  3. Identify your highest-cost interchange categories and address downgrades
  4. Request a markup reduction at your 12-month anniversary with clean history
  5. At $500K+/month, use competing offers to drive markup below 1.0%

Case Study: Switching from Tiered to Interchange-Plus

Merchant profile: Online coaching company, $120,000/month average volume, 80% Visa/Mastercard credit cards, 20% debit

Before (tiered pricing):

  • All credit card transactions: 2.85% + $0.25 (quoted as "qualified")
  • Rewards cards (which are 65% of credit volume): 3.65% + $0.25 ("non-qualified")
  • Debit transactions: 2.85% + $0.25 (same as "qualified" -- no debit savings passed through)
  • Monthly fee: $25
  • Transaction volume: 600 transactions/month

Effective rate calculation:

  • Credit transactions (480 × $200 average): $96,000 volume
    • 35% at 2.85%: $33,600 × 2.85% = $957.60
    • 65% at 3.65%: $62,400 × 3.65% = $2,277.60
    • Transaction fees: 480 × $0.25 = $120
  • Debit transactions (120 × $200 average): $24,000 volume
    • 120 × 2.85%: $684.00
    • Transaction fees: 120 × $0.25 = $30
  • Monthly fee: $25
  • Total fees: $4,094.20
  • Effective rate: 4,094.20 / 120,000 = 3.41%

After (interchange-plus at IC + 1.25% + $0.10):

  • Credit card average interchange: 1.85% (blend of standard and rewards)
  • Total credit cost: 1.85% + 1.25% = 3.10% + $0.10 per transaction
  • Debit card interchange (regulated): 0.05% + $0.21 flat
  • Total debit cost: 0.05% + 1.25% = 1.30% + $0.31 per transaction

New effective rate calculation:

  • Credit transactions: $96,000 × 3.10% + 480 × $0.10 = $2,976 + $48 = $3,024
  • Debit transactions: $24,000 × 1.30% + 120 × $0.31 = $312 + $37.20 = $349.20
  • Monthly fee: $0
  • Total fees: $3,373.20
  • Effective rate: 3,373.20 / 120,000 = 2.81%

Monthly savings: $721 ($4,094 vs. $3,373) Annual savings: $8,652

This is a real-world example of the savings available from switching from tiered to interchange-plus, even with modest volume. At $500,000/month, the same differential saves $36,000/year.


Interchange-Plus vs. Flat Rate: The Debit Card Advantage

The most significant advantage of interchange-plus over flat-rate pricing (like Stripe's 2.9% + $0.30) is the debit card pass-through.

Under Durbin Amendment regulation, debit cards from banks with over $10 billion in assets (Chase, Wells Fargo, Bank of America, Capital One, etc.) are capped at $0.21 + 0.05% interchange per transaction. For a $100 transaction, that's $0.26 in interchange -- dramatically below the 2.9% + $0.30 flat rate.

The calculation at scale: A merchant with 40% debit card volume at $200 average order value:

  • Flat rate (2.9% + $0.30): $200 × 2.9% + $0.30 = $6.10 per debit transaction
  • Interchange-plus (IC + 1.5% + $0.10): $200 × (0.05% + 1.5%) + ($0.21 + $0.10) = $3.10 + $0.31 = $3.41 per debit transaction

The savings: $2.69 per debit transaction. At 400 debit transactions/month: $1,076/month in savings just from debit.

Most flat-rate processing options (Stripe, Square) are not available to high-risk merchants. But the comparison illustrates why interchange-plus is structurally more cost-effective for merchants with significant debit volume.


Corporate Cards and Level 2 / Level 3 Processing

For B2B merchants who accept corporate purchasing cards, Level 2 and Level 3 data processing can significantly reduce interchange costs.

Level 2 data includes:

  • Customer code (reference number)
  • Tax amount
  • Zip code of purchase

Level 3 data adds:

  • Line item details (product description, quantity, unit cost)
  • Ship-to address
  • Commodity code

Interchange reduction from Level 2/3:

  • Standard corporate card without Level 2/3: ~2.95% interchange
  • Same card with Level 2 data: ~2.10% interchange
  • Same card with Level 3 data: ~1.85% interchange

For B2B merchants processing $200,000/month in corporate cards, adding Level 2 data reduces interchange costs by approximately $1,700/month. Level 3 data reduces costs by approximately $2,200/month.

Which payment gateways support Level 2/3 data: NMI, Authorize.net, and most enterprise gateways support Level 2/3 data fields. Your payment gateway and acquiring bank both need to support the data transmission for the reduced interchange to apply.


Monitoring Your Interchange-Plus Rates: Monthly Review Process

Establish a monthly statement review process to catch interchange issues early.

Step 1: Calculate your effective rate Total fees (all line items) divided by gross processing volume. Track month over month.

Step 2: Review interchange category breakdown Your statement should show transaction counts and volumes per interchange category. Look for:

  • Higher-than-expected volume in premium interchange categories (may indicate unusual card mix)
  • "Downgraded" transaction categories (key-entered, late settlement, etc.)
  • Unexplained fee line items

Step 3: Compare chargeback fees Total chargeback fees divided by number of chargebacks = fee per chargeback. Confirm this matches your agreement terms.

Step 4: Verify reserve activity Confirm reserve contributions and releases match your agreement terms and the expected rolling schedule.

Step 5: Flag anomalies If effective rate increased month-over-month without volume changes, investigate the interchange breakdown for the cause.

This 20-minute monthly review catches rate changes, downgrade issues, and fee anomalies before they compound.


Interchange-Plus at Different Business Stages

Startup phase ($0-$30K/month): Interchange-plus is available at most high-risk ISOs regardless of volume. Markup is higher at startup (1.75%-2.5%) but still structurally better than tiered pricing.

Growth phase ($30K-$200K/month): The 12-month anniversary is the primary leverage point. Bring 12 months of clean statements and request a 0.25%-0.5% markup reduction. This is standard practice -- most processors will accommodate it.

Scale phase ($200K-$1M/month): At this volume, use multiple processor quotes to drive competitive tension. A 0.25% markup reduction at $500K/month saves $1,250/month. Annual renegotiation is standard for merchants at this scale.

Enterprise phase ($1M+/month): Membership-model pricing becomes viable (flat monthly fee + interchange at direct cost with minimal markup). This model requires a direct bank relationship or very high-volume ISO placement.


Choosing a Processor Based on Pricing Structure

When evaluating processors, the pricing structure is the most important factor in long-term cost.

Questions to ask every processor:

  1. "Is this interchange-plus or tiered pricing?" (Non-negotiable: require interchange-plus)
  2. "What is your markup -- percentage and per-transaction?" (Get both components in writing)
  3. "What is your monthly account fee?" (Often negotiable to $0 for high-volume merchants)
  4. "What are your chargeback fees?" (Compare specifically: $35 vs. $75 matters at scale)
  5. "Do you have a rate lock or can you increase rates unilaterally?" (30-day notice minimum)

Gray Merchants provides all of this information in writing before you sign anything. Our markup is documented, our fee schedule is clear, and we don't have hidden costs.

Understanding Your Billing Statement in Detail

A proper interchange-plus statement includes more data than most merchants review. Here is a section-by-section guide.

Section 1: Summary page Shows total volume, total transactions, total fees, and effective rate. This is the high-level view. If effective rate increased from last month, dive into sections below.

Section 2: Interchange cost breakdown Lists every interchange category with: category name, transaction count, total volume, interchange rate, and total interchange cost. This section is the core of interchange-plus transparency.

Common interchange categories you should recognize:

  • CPS/Retail (card present, non-rewards): lowest credit card rate, ~1.51%
  • CPS/Card Not Present (CNP standard): typical online rate, ~1.65%
  • Visa Signature Preferred (premium rewards): ~2.10%
  • Regulated Debit (Durbin-capped): $0.21 + 0.05%
  • Non-Qualified/Downgraded: varies, check the specific downgrade reason

Section 3: Processor markup Your markup fee, broken out as: total volume processed x markup percentage + transaction count x per-transaction fee. Confirm this matches your agreement.

Section 4: Other fees Monthly account fee, gateway fee (if applicable), chargeback fees, retrieval fees, PCI compliance fee (annual or monthly). Each should match your fee agreement.

Section 5: Rolling reserve summary Reserve contributions this month, reserve releases this month, current reserve balance. Confirm the math: last month's balance + contributions - releases = current balance.

Section 6: Chargeback summary Number of chargebacks, total dispute amount, chargeback fees charged, win/loss record if you represented disputes. If chargebacks are increasing, this is your early warning.


Interchange-Plus Markup Benchmarks for High-Risk Industries

Knowing the market rates for your specific industry helps you evaluate whether your current markup is competitive.

Below-market (exceptional, requires strong history and high volume):

  • Markup under 1.0% + $0.10 for most industries

Market rate (12+ months clean history, $50K-$500K/month):

  • Nutraceuticals/supplements: 1.25%-1.75% + $0.10-$0.15
  • CBD/hemp: 1.5%-2.0% + $0.15
  • Online coaching/consulting: 1.0%-1.5% + $0.10
  • Firearms (card present): 1.0%-1.5% + $0.10
  • Travel agencies: 1.5%-2.0% + $0.15
  • Subscription boxes: 1.25%-1.75% + $0.15

Above-market (new merchant, elevated chargeback history, or complex vertical):

  • Markup over 2.5% + $0.20 should be questioned after 12 months of clean history

If your markup is above market and you have 12+ months of clean processing, use competing offers from other ISOs to negotiate down. Gray Merchants can provide a competitive quote for any established high-risk merchant.


Final Thoughts: Interchange-Plus as a Foundation for Sustainable Processing

Interchange-plus pricing is not just a cost optimization -- it is a transparency principle. Merchants on interchange-plus understand exactly what they pay and why. They can track changes in their card mix. They can identify downgrade problems. They can negotiate from a position of knowledge.

Merchants on tiered pricing are flying blind. They pay what the processor decides to charge them, with no visibility into the underlying cost structure. The result is consistently higher effective rates that compound over years.

Every Gray Merchants account is set up on interchange-plus from day one, with full written documentation of your markup before you sign.

Understanding Interchange-Plus in Practice: A Summary

Interchange-plus pricing gives you complete visibility into your payment processing costs. Every dollar you pay is traceable: interchange cost (Visa/Mastercard), assessment fees (card network fees), and your processor's markup. The combination of this transparency and the structural cost advantage -- particularly for debit card processing and merchants with rewards card-heavy customer bases -- makes interchange-plus the preferred pricing model for any high-risk merchant processing more than $10,000 per month.

The single most valuable action you can take with your current payment processing is confirming you are on interchange-plus (not tiered), calculating your effective rate, and comparing it to the industry benchmarks above. If you find you are on tiered pricing or paying above-market markups, Gray Merchants will provide a competing quote with full rate documentation within 24 hours.

The merchants who achieve the lowest effective rates in high-risk processing are those who understand interchange-plus deeply, optimize their downgrade rates, negotiate their markup aggressively at review points, and treat their payment infrastructure as a strategic business function. Apply these principles and your processing costs will decrease year over year even as your volume grows. Apply with Gray Merchants today.
