Credit card processing fees are one of the most common — and often misunderstood expenses businesses face when accepting electronic payments. Whether a customer pays using a credit card, debit card, digital wallet, or online checkout, multiple financial institutions and payment providers work behind the scenes to authorize and complete the transaction. Each party involved typically receives a portion of the processing fee.

For many businesses, these fees can quickly add up and significantly impact profit margins over time. However, not all processing fees are the same. Costs can vary depending on the payment method, industry type, card used, pricing model, and even how the transaction is entered. Understanding how processing fees work is essential for businesses looking to better manage payment costs and avoid unnecessary expenses.

In this guide, we’ll break down what processing fees are, how they are calculated, the different types of credit card processing fees businesses may encounter, and practical ways to reduce overall payment processing costs. We’ll also explain common pricing models, industry averages, and strategies businesses use to offset or lower processing expenses.

What is a processing fee?

A processing fee is the cost businesses pay to accept electronic payments such as credit cards, debit cards, ACH transfers, digital wallets, and online payments. These fees are typically charged every time a customer completes a transaction and are used to cover the cost of securely moving money from the customer’s payment method to the merchant’s bank account.

Where do processing fees go to?

Processing fees do not go to a single company. Instead, the fee is typically divided among several parties involved in processing and securing the payment transaction.

When a customer pays with a credit card or debit card, multiple financial institutions and technology providers work together behind the scenes to authorize, route, approve, and settle the payment. Each participant receives a portion of the processing fee for their role in the transaction.

The main parties that receive portions of the processing fee include:

The Card-Issuing Bank

The issuing bank is the financial institution that provided the customer’s credit or debit card. This bank usually receives the largest portion of the processing fee through what is known as the interchange fee.

Interchange fees help cover:

• Fraud protection
• Credit risk
• Rewards progams
• Transaction authorization
• Banking infrastructure

For most transactions, interchange fees represent the biggest percentage of the total processing cost.

The Card Networks

Card networks such as Visa, Mastercard, Discover, and American Express also receive a portion of the processing fee. These are commonly called assessment fees or network fees.

Card networks are responsible for:

• Operating the payment network
• Routing transaction data
• Setting interchange rules
• Maintaining security standards
• Managing communications between banks and processors

Although assessment fees are usually smaller than interchange fees, they are charged on nearly every card transaction.

The Payment Processor or Merchant Services Provider

The payment processor or merchant services provider receives the remaining portion of the fee, commonly referred to as the processor markup.

The processor helps businesses:

• Accept card payments
• Connect payment terminals and POS systems
• Process online transactions
• Handle settlement and reporting
• Manage payment security and compliance
• Support chargeback and dispute management

Depending on the provider, the processor may also charge additional monthly or account-related fees for software, reporting tools, PCI compliance, or equipment services.

In simple terms, processing fees are shared among the financial institutions and technology providers that make electronic payments possible. Each party plays a role in securely moving funds from the customer’s payment method into the business’s bank account.

How are processing fees calculated?

Processing fees are typically calculated using a combination of:

• A percentage of the transaction amount
• A fixed per-transaction fee

In most cases, businesses pay a fee structure that looks similar to this example below:

In this example:

• Percentage fee: $2.90
• Fixed transaction fee: $0.30
• Total processing fee: $3.20

Types of Credit Card Processing Fees

Credit card processing fees are made up of several different charges that work together to process, approve, secure, and settle electronic payments. Some fees are charged on every transaction, while others are recurring account or service-related fees.

Understanding these fees can help businesses better compare payment processors and identify unnecessary costs.

Interchange Fees

Interchange fees are usually the largest part of a processing fee. These fees are paid to the customer’s card-issuing bank whenever a credit or debit card is used.

Interchange fees help cover:

• Fraud Prevention
• Payment Authorization
• Banking infrastructure
• Card rewards programs
• Transaction risk

Assessment Fees

Assessment fees are charged by card networks such as:

• Visa
• Mastercard
• Discover
• American Express

These fees help maintain the payment networks that securely route transactions between banks and processors.

Payment Processor Fees

Payment processors charge their own markup for handling the transaction and providing payment services.

Processor fees may help cover:

• Payment gateway services
• POS integrations
• Reporting tools
• Customer support
• Transaction settlement
• Fraud monitoring

Additional Fixed Fees

Some payment providers may also charge recurring or account-related fees beyond standard transaction costs.

Common examples include:

• Equipment rental fees
• Monthly processor fees
• POS software fees
• Monthly minimum fees
• Statement fees
• PCI compliance fees
• Secure card-on-file storage fees

Risk and Dispute Fees

Certain fees only occur when there is a payment dispute or account issue.

These may include:

• Chargeback fees
• Retrieval fees
• Early termination fees

Chargeback and retrieval fees are commonly charged when customers dispute transactions, while early termination fees may apply if a merchant cancels a processing contract before the agreed term ends.

Credit card processing pricing models

Payment processors use different pricing structures to determine how businesses are charged for accepting card payments. The pricing model a business chooses can significantly impact its overall processing costs, transparency, and monthly fees.

The most common credit card processing pricing models include flat-rate pricing, interchange-plus pricing, and tiered pricing.

Flat-Rate Pricing

Flat-rate pricing charges the same fixed rate for every transaction, regardless of the card type or interchange category.

For example, a processor may charge:

• 2.9% + $0.30 for online payments
• 2.6% + $0.10 for in-person payments

Flat-rate pricing is popular with small businesses because it is:

• Simple to understand
• Predicatable
• Easy to budget

However, businesses processing higher transaction volumes may sometimes pay more overall compared to other pricing models.

Interchange-Plus Pricing

Interchange-plus pricing separates the interchange fee from the processor’s markup.

Under this model, the business pays:

• The actual interchange fee set by the card networks and issuing banks
• Plus an additional processor markup

For example:

• Interchange + 0.30% + $0.10

Many businesses consider interchange-plus pricing to be one of the most transparent pricing models because it clearly shows what portion goes to the bank and what portion goes to the processor.

Tiered Pricing

Tiered pricing groups transactions into different pricing tiers, commonly:

• Qualified
• Mid-qualified
• Non-qualified

The rate charged depends on factors such as:

• Card type
• How the card was processed
• Rewards card usage
• Whether the transaction was keyed-in or in-person

While tiered pricing may appear simple at first, it can sometimes make merchant statements more difficult to understand because transactions may qualify for different rates depending on the payment details.

Average credit card processing fees by industry

Credit card processing fees can vary significantly depending on the industry, business risk level, average transaction size, and how payments are accepted. Businesses that process more online transactions or experience higher chargeback rates often pay higher processing costs than businesses primarily accepting in-person payments.

Below are common average effective processing fee ranges by industry:

Several factors can influence where a business falls within these ranges, including:

• Several factors can influence where a business falls within these ranges, including:
• Average ticket size
• Chargeback frequency
• Rewards card usage
• Debit vs credit card mix
• Pricing model used by the processor
• Industry risk classification

In general:

• In-person chip transactions usually have lower fees
• Online and manually keyed-in payments typically cost more
• Debit card transactions often carry lower interchange fees than credit cards
• Businesses with lower fraud and chargeback risk may qualify for better rates

Because pricing structures vary widely between providers, many businesses calculate their effective processing rate monthly to better understand their true payment processing costs.

How to Reduce Processing Fees

While credit card processing fees are unavoidable for most businesses, there are several ways to reduce overall payment processing costs and improve effective processing rates.

Choose the Right Pricing Model

The pricing structure used by a payment processor can significantly impact total fees. Many businesses compare:

• Flat-rate pricing
• Interchange-plus pricing
• Tiered pricing

For higher-volume businesses, interchange-plus pricing may provide greater transparency and lower overall costs compared to flat-rate or tiered models.

Encourage In-Person Payments

Card-present transactions processed through chip readers or tap-to-pay terminals generally have lower fees than online or manually keyed-in transactions because they carry lower fraud risk.

Reduce Keyed-In Transactions

Manually entering card information often results in higher interchange fees and increased fraud exposure. Using chip readers, contactless payments, or digital wallets can help reduce processing costs.

Optimize Debit Card Usage

Debit card transactions frequently carry lower processing fees than credit cards. Some businesses encourage debit payments to help lower average transaction costs.

Lower Chargebacks and Fraud

Chargebacks and fraud-related disputes can increase processing costs over time. Businesses can help reduce disputes by:

• Using EMV chip readers
• Providing clear receipts
• Maintaining accurate billing descriptors
• Improving customer service
• Using fraud prevention tools

Review Monthly Statements

Many businesses pay hidden or unnecessary fees without realizing it. Regularly reviewing merchant statements can help identify:

• Unused services
• Excessive processor markups
• Duplicate fees
• Unnecessary equipment rentals
• High-risk surcharges

Negotiate Processing Rates

Businesses with growing transaction volume may be able to negotiate lower rates or reduced markups with their payment processor. Even small rate reductions can lead to significant long-term savings.

Consider Cash Discount or Dual Pricing Programs

Some businesses offset processing costs by implementing:

• Cash discount programs
• Dual pricing programs
• Surcharging (where permitted)

These pricing strategies can help reduce or partially offset credit card processing expenses when implemented properly and in compliance with card network rules and state regulations.

Frequently Asked Questions About Processing Fees

Is it legal for merchants to charge credit card processing fees to customers?

In many states, businesses are allowed to pass certain processing costs to customers through methods such as surcharging, cash discount programs, or dual pricing. However, rules vary by state, card network, and payment processor, so businesses must follow disclosure and compliance requirements before implementing these pricing strategies.

Why do card companies charge processing fees?

Processing fees help cover the costs associated with securely authorizing, routing, processing, and settling electronic payments. These fees also support fraud prevention, payment network infrastructure, transaction risk management, and rewards programs offered by many credit cards.

What is the average credit card processing fee?

Most businesses pay an average effective processing rate between 1.5% and 3.5% per transaction. The exact rate depends on several factors, including the industry, card type, payment method, pricing model, and whether the transaction is processed online or in person.

How can I reduce or eliminate credit card processing fees?

Businesses may reduce processing costs by:

• Negotiating better rates
• Using interchange-plus pricing
• Encouraging in-person payments
• Lowering chargebacks and fraud
• Reviewing merchant statments for hidden fees
• Implementing cash discount or dual pricing programs

Some businesses use compliant pricing programs to offset a portion of their processing costs, though complete elimination of fees may not always be possible depending on the payment setup.

Why are online credit card processing fees usually higher?

Online and manually keyed-in transactions are generally considered higher risk because the physical card is not present during the transaction. Because of the increased fraud risk, card-not-present transactions often carry higher interchange and processing fees compared to in-person chip or tap payments.
