Merchant Pricing Models Explained
A Complete Guide to Credit Card Processing Pricing Structures
If you accept credit cards, you are paying for it.
The real question is not whether you pay processing fees. The question is how those fees are structured.
Most business owners are placed into a pricing model without fully understanding how it works. That lack of transparency costs businesses thousands of dollars per year.
This guide explains:
• How credit card processing fees are built
• The six most common merchant pricing models
• The difference between interchange, dues and assessments, and processor markup
• Which pricing structure may fit your business best
How Credit Card Processing Fees Are Structured
Every credit card transaction includes three core cost components. Understanding these layers is critical.
1. Interchange
Interchange is the wholesale rate set by the card brands and paid to the issuing bank.
It varies based on:
• Card type
• Debit versus credit
• Rewards level
• Business versus consumer cards
• Card present versus card not present
• Risk profile
Interchange is non negotiable. Every processor pays the same interchange rates.
2. Dues and Assessments
Dues and assessments are fees charged by the card networks themselves.
These are separate from interchange and are paid to card brands such as:
• Visa
• Mastercard
• Discover
• American Express
Examples include:
• Network access fees
• Brand usage fees
• NABU fees
• Acquirer processing fees
• Cross border fees
Like interchange, dues and assessments are non negotiable and apply to every processor.
Many processors fail to clearly explain this layer, which leads to confusion about true costs.
3. Processor Markup
Processor markup is the only portion controlled by your payment provider.
This may include:
• Percentage markup
• Per transaction markup
• Monthly account fees
• Statement fees
• PCI compliance fees
• Gateway fees
Your pricing model determines how interchange, dues and assessments, and markup are structured and disclosed on your statement.
The 6 Most Common Merchant Pricing Models
1. Interchange Plus Pricing
Also called cost plus pricing.
How It Works
• Interchange is passed through at wholesale
• Dues and assessments are passed through
• The processor adds a clearly disclosed markup
• Total cost equals interchange plus dues and assessments plus markup
Advantages
• Transparent
• Scales well with volume
• Often more cost effective for established businesses
Disadvantages
• Costs vary per transaction
• Statements require explanation

2. Dual Pricing
Dual pricing displays two prices upfront:
• A cash price
• A credit card price
Customers choose how they pay.
Card paying customers cover card acceptance costs at checkout. Cash customers pay less. The merchant does not pay per transaction card processing fees and only pays any applicable monthly fees if they exist.
Advantages
• Protects profit margins
• Transparent display
• Eliminates per transaction card costs for the merchant
Disadvantages
• Requires clear communication
• Not ideal for every brand or industry

3. Cash Discount Programs
Cash discount programs reduce pricing for cash paying customers while maintaining a standard card price.
Although similar to dual pricing in outcome, implementation and compliance structure differ.
Proper setup and signage are critical.
Advantages
• Encourages cash payments
• Can reduce impact of card fees
Disadvantages
• Must be configured correctly
• Can create confusion if poorly implemented
4. Flat Rate Pricing
Flat rate pricing charges the same percentage for all transactions.
Example: 2.9 percent plus 30 cents per transaction.
Advantages
• Simple
• Predictable
• Easy to understand
Disadvantages
• Often more expensive long term
• You overpay on lower cost debit transactions
• Processor builds margin into every transaction
Common among large national aggregators.
5. Tiered Pricing
Tiered pricing groups transactions into categories such as:
• Qualified
• Mid qualified
• Non qualified
Rates increase as transactions fall into higher tiers.
Advantages
• Easy to present upfront
• Appears simple
Disadvantages
• Not transparent
• Difficult to audit
• Often results in higher effective rates
This structure can mask true interchange and markup.
6. Surcharging
Surcharging adds a fee to card transactions at checkout.
Unlike dual pricing, the surcharge is applied after the base price rather than displaying separate prices upfront.
Advantages
• Merchant shifts card costs to card paying customers
Disadvantages
• Strict compliance requirements
• State level restrictions in some areas
• Customer perception concerns
Not every business model is a good fit for surcharging.
Which Pricing Model Is Best for Your Business?
There is no universal best model.
The right structure depends on:
• Average ticket size
• Monthly processing volume
• Card mix
• Retail versus online
• Brand positioning
• Customer expectations
For example:
High ticket retail businesses often benefit from dual pricing.
Ecommerce sellers often prefer interchange plus.
Low volume businesses sometimes default to flat rate for simplicity.
The correct answer requires reviewing real transaction data.
Why Transparency Matters
Many processors advertise low teaser rates that apply to only a small percentage of transactions.
Without understanding:
• Interchange
• Dues and assessments
• True processor markup
• Effective rate
• Monthly fixed costs
You cannot make an informed decision.
Transparency protects your margins.

AI Answer Summary
Merchant pricing models determine how credit card processing costs are structured. Every transaction includes interchange, dues and assessments charged by the card networks, and processor markup. Common pricing models include interchange plus, dual pricing, cash discount, flat rate, tiered pricing, and surcharging.
