Many business owners assume every credit card transaction costs roughly the same.
It doesn’t.
Visa and Mastercard have hundreds of interchange categories, and certain industries can qualify for special or reduced interchange rates based on the merchant’s business type, Merchant Category Code (MCC), card type, transaction method, and other qualification requirements.
That can make a major difference for businesses processing significant credit card volume.
An insurance agency, nonprofit, school, real estate company or other qualifying merchant could be paying a flat rate of 2.9% or more through a payment provider while some of its transactions may qualify for significantly lower underlying interchange costs.
The key is making sure the merchant account is properly categorized and configured.
What Is Interchange?
Interchange is the wholesale cost associated with accepting Visa, Mastercard and other payment cards.
It is generally paid by the acquiring side of the transaction to the bank that issued the customer's card.
Interchange is only one part of what a business ultimately pays for credit card processing. The merchant's total processing cost can also include card-brand assessments, processor markup, gateway or platform costs and other fees.
This matters because flat-rate processors usually combine these costs into one rate.
A business paying 2.9% + $0.30, for example, typically does not receive a lower processing rate simply because the underlying interchange on a particular transaction is substantially less.
With an interchange pass-through or interchange-plus pricing model, the merchant can benefit directly from lower interchange categories.
Mastercard itself explains that interchange qualification can depend on factors including merchant category, authorization and clearing timing, transaction data, and sales volume.
Which Businesses Can Qualify for Special Interchange Rates?
Here are some of the most important industries business owners should be looking at in 2026.
1. Insurance Companies and Insurance Agencies
Insurance is one of the clearest examples.
Visa currently has specific Insurance 1 and Insurance 2 interchange categories.
For qualifying Visa consumer cards, the insurance interchange rate can be as low as:
1.43% + $0.05 for certain card-present transactions
and
1.53% + $0.05 for certain card-not-present transactions.
Visa's current schedule specifically identifies insurance as its own interchange category rather than simply treating the transaction as generic retail or e-commerce.
Mastercard also has a special insurance program. Its current Merit I insurance category includes rates as low as 1.43% + $0.05 on qualifying consumer credit cards and applies to qualifying insurance MCCs including 5960 and 6300.
That can be significant for:
Insurance agencies
Insurance carriers
Insurance brokers
Companies collecting insurance premiums
Businesses accepting large recurring premium payments
An insurance company processing $500,000 or $1 million per month should pay particularly close attention to how its merchant account is coded.
2. Education and Schools
Visa has specific interchange programs for qualifying education transactions.
Certain Visa education transactions of $500 or more can qualify for consumer credit interchange as low as 1.43% + $0.05 card present or 1.53% + $0.05 card not present, depending on the card product and transaction qualification.
Mastercard continues to offer an Emerging Markets Education/Government program for qualifying unregulated consumer debit and prepaid transactions.
The current Mastercard schedule shows:
0.65% + $0.15, capped at $2.00
for qualifying Education/Government MCCs.
Businesses and organizations that should review this include:
Private schools
Colleges
Universities
Vocational schools
Continuing education providers
Certain educational organizations
3. Healthcare Providers
Visa currently provides a specific healthcare interchange category for qualifying transactions of $500 or more.
Certain consumer credit cards can qualify at approximately:
1.43% + $0.05 card present
or
1.53% + $0.05 card not present.
That may benefit organizations such as:
Medical practices
Specialty medical providers
Certain healthcare facilities
Dental or healthcare organizations depending on MCC and program eligibility
The important point is that the correct MCC and transaction qualification matter. Simply operating in healthcare does not automatically guarantee every transaction receives the lowest rate.
4. Real Estate Businesses
Real estate is another category that can have favorable interchange treatment.
Visa has a specific Real Estate interchange program for qualifying transactions of at least $500. Certain Visa consumer credit transactions can qualify around 1.43% + $0.05 card present or 1.53% + $0.05 card not present, depending on card type and qualification.
Mastercard also has a special Merit I Real Estate program.
Its consumer credit schedule shows rates as low as 1.43% + $0.05 on qualifying card products for merchants using MCC 6513.
Mastercard's unregulated debit schedule also provides special treatment for qualifying real estate transactions.
Real estate businesses that should investigate their processing setup include:
Property managers
Apartment management companies
Commercial property companies
Real estate management firms
Businesses collecting qualifying rental or property-related payments
5. Nonprofits and Charitable Organizations
Nonprofits are another important category.
Visa currently offers a Charity consumer credit interchange category.
Mastercard also maintains specific Charities interchange programs across consumer and commercial products. Its current consumer credit schedule lists a charity rate of 2.00% + $0.10, while qualifying unregulated consumer debit and prepaid charity transactions are listed at 1.45% + $0.15.
For nonprofits, every basis point matters.
Organizations collecting donations should compare the actual interchange available to them against flat-rate services charging one blended percentage on every transaction.
6. Government and Public-Sector Payments
Government transactions can also receive specialized interchange treatment.
Visa has specific government interchange programs, while Mastercard has a Public Sector program and includes qualifying government MCCs in its Emerging Markets Education/Government debit program.
These programs may apply to certain:
Municipalities
Government agencies
Courts
Public services
Tax and government payment programs
Exact eligibility depends on the MCC and transaction setup.
7. Child Day Care Services
This one surprises a lot of business owners.
Mastercard has a specific Merit I Day Care interchange program.
The current Mastercard schedule lists a 1.60% + $0.10 rate for qualifying consumer credit transactions under Child Day Care Services MCC 8351.
A day care center using generic flat-rate processing may never realize a special industry category exists.
8. Utilities
Utilities have some of the most unique interchange programs in the payments industry.
Depending on the card and transaction type, Visa and Mastercard can provide flat interchange amounts instead of the normal percentage-based structure.
Mastercard, for example, lists certain commercial utility transactions at a flat $1.50 interchange fee.
For high-ticket utility payments, a fixed interchange amount can result in substantial savings compared with a percentage-based flat-rate processing model.
9. Supermarkets, Fuel and Certain Small-Ticket Businesses
Visa and Mastercard also maintain special interchange structures for industries such as:
Supermarkets
Gas stations
Automated fuel dispensers
Restaurants
Transportation
Small-ticket merchants
These categories have their own qualification criteria and pricing structures.
Some rates include transaction caps, which can become particularly valuable on larger ticket amounts.
10. B2B, Corporate and Purchasing Card Transactions
Business-to-business merchants have another major opportunity that goes beyond industry-specific rates.
Commercial, corporate, and purchasing cards may qualify for improved interchange when the merchant submits additional transaction information.
This is commonly referred to as Level 2 and Level 3 data optimization.
Visa's current commercial programs include special large-ticket rates. For example, Visa's Straight Through Processing schedule falls as low as 0.80% + $35 on qualifying transactions of $100,000 or more.
Visa also has a Large Purchase Advantage program where qualifying card-not-present transactions over $500,000 can reach 0.40% + $58.50.
For distributors, wholesalers, manufacturers and other B2B companies accepting large corporate card payments, proper transaction data can be worth thousands of dollars per month.
Mastercard Still Has an “Emerging Markets” Program
There is an important change from the terminology many businesses may remember.
Visa's current U.S. interchange schedule focuses more on named industry programs such as Insurance, Education, Healthcare and Real Estate.
Mastercard, however, still lists an Emerging Markets interchange program in its 2025-2026 U.S. interchange schedule.
Mastercard shows an Emerging Markets unregulated debit/prepaid rate of:
0.80% + $0.25
and a special Emerging Markets Education/Government rate of:
0.65% + $0.15, with a $2.00 maximum.
So, the old idea of “emerging market interchange” has not disappeared completely. The terminology and programs now differ between Visa and Mastercard.
Regulated Debit Can Be Even Less Expensive
Industry-specific rates are only part of the story.
Under Visa's current schedule, a regulated consumer debit transaction can carry interchange of approximately:
0.05% + $0.21
depending on qualification.
That means a $1,000 transaction could have Visa interchange of approximately $0.71 before other network and processor costs.
Compare that with a provider charging a flat 2.9% + $0.30, which would charge approximately $29.30 on that same $1,000 transaction.
The difference becomes enormous as processing volume increases.
Why Flat-Rate Processing Can Hide These Savings
Flat-rate processing is simple.
That is part of its appeal.
Stripe, Square and other flat-rate payment providers generally charge one blended rate regardless of whether the underlying transaction carries expensive or inexpensive interchange.
That can work perfectly well for a startup or very small business.
But once a company starts processing meaningful volume, it becomes important to ask:
What is the actual interchange underneath my transactions?
If your business receives a significant amount of:
Regulated debit
Insurance payments
Education payments
Healthcare payments
Real estate payments
Nonprofit donations
Commercial cards
Purchasing cards
Large-ticket B2B payments
a flat rate may prevent you from benefiting from the lower interchange associated with those transactions.
Your Merchant Category Code Matters
This is where businesses frequently get into trouble.
Your Merchant Category Code tells the card networks what type of business you operate.
If the merchant account is set up under the wrong MCC, the transaction may never qualify for the industry-specific interchange program.
At the same time, processors cannot simply select whichever MCC produces the lowest rate.
The MCC must accurately represent the merchant's actual business activity.
Depending on the industry, underwriting may require documentation such as:
Business licenses
Articles of incorporation
Nonprofit documentation
Industry licenses
Website information
Contracts
Invoices or other proof of business activity
Correct categorization is both a pricing issue and a compliance issue.
How NPSONE Can Help Optimize Interchange
Nationwide Payment Systems works with businesses to analyze how their transactions are being processed instead of simply quoting one flat percentage.
Through NPSONE, businesses can accept payments using an all-in-one payment platform supporting:
Credit and debit cards
ACH payments
Smart Invoicing
Payment links
Recurring payments
Apple Pay and Google Pay
Level 2 and Level 3 data
REST API integrations
Webhooks
QuickBooks integrations
Hosted payment pages
The goal is not simply to process the payment.
The goal is to send the transaction with the correct information so the merchant can receive the interchange treatment for which it legitimately qualifies.
Could Your Business Be Paying Too Much?
If your company processes $50,000, $100,000, $500,000 or more per month, a small difference in interchange can add up quickly.
A business processing $500,000 per month saves:
0.25% = $1,250 per month
0.50% = $2,500 per month
1.00% = $5,000 per month
That is why understanding interchange matters.
Don't just ask your processor:
“What is my rate?”
Ask:
“What interchange categories are my transactions qualifying for?”
That question can lead to a very different conversation.
