What are Credit Card Processing Fees?

In a Nutshell

While no one really loves forking over money to make money, it’s important to know which credit card processing fees are relevant to your business and how much you can expect to pay per transaction. This article will go over these fees in greater detail, from how they break down and who assesses them, to how you can ultimately reduce them.

Crucial Information & Tips to Reduce Your Credit Card Processing Fees

If you accept credit cards, you can expect fees to eat up 1% to 3.5% of every transaction you submit for processing. Figuring out exactly how much you’ll pay in fees depends on a lot of factors, though.

You have to account for your payment processor’s fee structure, your line of business, and the type of cards you accept. Whether you conduct online or in-person transactions (or both) will be a big factor, too.

In this article, we take a closer look at payment processing fees. I’ll break down how those fees get calculated, and also offer a few tips and tricks that you can implement to keep your costs down.

What are Credit Card Processing Fees?

Credit Card Processing Fee

[noun]/krə • dət • kard • prä • səs • iNG • fē/

Credit card processing fees are the costs that merchants pay to process card transactions. These fees cover the operational and technological expenses associated with processing payments, including the transfer of funds between the cardholder's bank (issuing bank) and the merchant's bank (acquiring bank).

Payment processing fees are costs that you pay for the privilege of accepting credit, debit, and prepaid cards. Issuers, card networks, and payment processors all assess fees every time a transaction is processed. The fees are typically expressed as a percentage of the transaction amount.

Processing fees are sometimes stated as a single figure, but they can really be broken down into four, more specific fees:

Interchange Fees

Interchange Fees

These fees are set by the card networks, but are allocated to the issuing bank. Interchange fees may vary based on factors like card type, transaction method, and merchant industry. This usually represents the largest portion of the discount rate.

Assessment Fees

Assessment Fees

These fees are charged by the card networks (e.g., Visa, Mastercard) for the use of their infrastructure and services. Assessment fees are typically a small percentage of the overall transaction amount.

Processor Fees

Processor Fees

These fees are set and charged by the payment processor for their role in facilitating the transaction. Processor fees can include a percentage of the transaction amount, a fixed per-transaction fee, and/or a monthly fee.

Processor Fees

Acquirer Fees

Your acquiring bank may also assess fees for their services, such as account maintenance fees or additional transaction fees.

Cardholder transaction:
$100
Assessment fee:

Acquiring fee:

The merchant paid a total of $2.35 in processing fees
Merchant Discount Rate is 2.35%
Common QuestionWho Has to Pay Processing Fees?The merchant is responsible for paying card processing fees. They can pass these costs along to customers in the form of higher prices or added surcharges, making goods and services more expensive for customers. Imposing fees on customers is increasingly rare, though, as cards become the default preferred payment method.

Are Processing Fees the Same as Interchange Fees?

TL;DR

No. Interchange fees make up the majority of the fees you pay to process a transaction. But, most people use “processing fees,” to refer collectively to interchange fees, the processor markup, and card network assessment fees.

Like I mentioned above, the credit card processing fees you pay are made up of several different, specific fees assessed by different parties in the value chain. Interchange fees, which are paid to issuers, are the largest component; they make up between 70-90% of total payment processing costs.

Network assessment fees are more minor; these fees are received by card networks, and they make up 3-10% of total processing costs, on average.

The remaining 7-20% of your processing fees comes in the form of a processor markup and acquiring fees. This is any amount over and above the sum of the interchange and network assessment fees that are passed onto you. Processor markups cover the processor’s operating costs, including software development, sales, customer support, legal expenses, and margins.

How are Payment Processing Fees Structured?

Credit card processing fees vary depending on the card swiped at checkout (card brand and rewards tier), the type of transaction (online or offline), and the markup charged by your payment processor.

As a general rule of thumb, you can start by calculating the interchange fee, plus the network assessment fee. The following table is an example of how interchange fees break down across some of the largest card networks (as of this writing):

Payment NetworkLow Interchange Fee RangeHigh Interchange Fee RangeAverage Assessment Fee
Visa1.15% + $0.053.15% + $0.100.14%
Mastercard1.25% + $0.053.15% + $0.100.1375% for transactions under $1,000; 0.01% for transactions of $1,000 or more
Discover1.45% + $0.053.05% + $0.100.13%
American Express1.35% + $0.103% + $0.100.15%

Merchants pay interchange fees via their payment processor. As we’ll see in the next section, these are typically rolled into other credit card processing fees assessed by the processor and acquirer.

How are Payment Processing Fees Structured?

When you contract with a payment processor, you pay interchange fees, plus fees assessed by your processor. These providers structure fees using one of several models: interchange-plus, subscription, tiered, or flat-rate structures:

Interchange-Plus Processing

This pricing method includes the interchange rate plus a markup, which can either be a fixed amount or percentage-based.

PRO

This method can be less costly than the others, especially for businesses that process a large number of transactions.

CON

Interchange rates can vary from transaction to transaction, making it difficult to predict costs month to month.

Example:

PayJunction assesses a fee that is equal to the interchange fee, plus 0.75% + $0.07 per transaction.

Flat-Rate Processing

Flat-rate pricing ensures a single rate for all transactions through a given method, regardless of interchange rates and fees. This would mean you’d pay a set percentage on top of your transaction rate; for example, 3% of the total plus $0.25 for every transaction.

PRO

Flat rates aren’t subject to fluctuation. You know what you’re getting into.

CON

It could be more expensive than the other tiers if a company processes many transactions annually.

Example:

PayPal assesses a fee of 2.60% + $0.10 per card-present transaction. For card-not-present sales, that fee increases to 2.90% + $0.30 per transaction, or 3.5% + $0.15 per each manual entry.

Tiered-Rate Processing

Tiered pricing combines both interchange-plus and flat-rate pricing by sorting rates into grouped categories. To illustrate this, let’s say that you might pay 2% plus $0.15 for debit transactions and 3% plus $0.10 for credit card transactions. These rates and fees are variable, following a predetermined ruleset.

PRO

Tiered pricing offers predictability combined with competitive pricing.

CON

If you process a large number of payments overall, the costs associated with a tiered pricing scale could be very high.

Example:

Veem assesses fees at 2.9% per transaction or 1% of total transaction amount for US transactions, and 3.9% per transaction or 1% of total transaction amount for international transactions.

Subscription

Subscription payment processing models are membership-based. Essentially, you pay a monthly fee to the payment processor and receive rates based on your selected (or earnings warranted) tier. You may have noticed that this payment model is very similar to the interchange plus model, although the rates and monthly fees tend to be much higher in exchange for lower per-transaction fees.

Subscription models are best suited for businesses with higher sales rates (of generally $10k and up per month).

PRO

There are no earning caps for subscription-based processing, nor are there usually any excessive chargeback penalties or limitations.

CON

Compared to the other tiers, subscription processing models can be much more expensive.

Example:

Payment Depot offers Starter (up to $125k per year) pricing at $59 per month + interchange + $0.15 per transaction, while Starter Plus (over $125k per year) runs at $79 per month + interchange + $0.10 per transaction.

Other Factors Impacting Credit Card Processing Fees

We now have a better understanding of how interchange and assessment fees affect your revenue. So, let’s dig into some additional circumstances and how they might impact your total fees. 

Remember, all total fees will combine interchange and assessment fees, no matter which processor you choose. From there, several factors influence your overall payout, including:

Your Payment Processor

Payment processors take on the majority of the exchange process for you, including haggling with the credit card networks. They will likely pay your credit card processing fees directly, and expect you to simply remunerate them via processing fees.

Industry & Vertical

Some product categories pose greater risks than others. For instance, if you run a travel business, health and beauty supply, or a gas station, you might be considered a “high-risk” merchant. This would mean you’d naturally pay higher credit card processing fees per transaction and higher monthly processing fees as well.

Business Size

The volume of credit card transactions you process can also impact your credit card processing fees. If your business processes over 20k per month, like a supermarket, you may be offered a lower per-transaction rate.

Card Type

The card used plays a big role in how much you will be expected to pay. Each card network has its own way of doing things, and that includes how much they charge to process credit and debit card transactions. For instance, Visa, Mastercard, Amex, and Discover all charge different assessment rates for credit cards. Additionally, debit cards and prepaid cards typically have lower fees than credit cards.

Channel

The environment in which you accept and process payments also influence the fees you will ultimately pay per transaction. For instance, card-not-present (CNP) transactions pose a greater risk, as it is easier to verify and authenticate consumers that are standing right in front of you rather than accept payment online. So, if you mainly do business online, your credit card processing fees will be higher than those paid by brick-and mortar-sellers.

Important!

Your processor may require you to obtain proprietary equipment to process card payments. These costs can fluctuate drastically from one end of the payment spectrum to another.

Some payment providers offer basic mobile readers for free (like Square), while others run around $50. If you need in-store terminals, however, equipment costs can run anywhere from $50-1,000. Whichever model and provider you choose, don’t forget to factor these costs into your bottom line.

Other Credit Card Processing Costs to Consider

Looking at ads from companies that handle payment processing, you'll see a lot of talk about their low rates. That's fine... but, when you're choosing a service, it's smart to remember that the rate they show in the ad might not be the full story.

There are lots of other fees that could add to what you pay in the end. These can include:

  • Application Fees
  • Setup Fees
  • Gateway Integration Fees
  • Per-Transaction Gateway Fees
  • Transaction or Batch Fees
  • Software Fees
  • Statement Fees
  • Reporting Fees
  • PCI Compliance/Certification Fees
  • Ongoing or expanded Customer Support Fees
  • Refund Fees
  • Address Verification Fees
  • Monthly Minimums or Recurring Payments Fees
  • Cancellation Fees
  • Merchant Account fees

Some fees are one-time costs. Others might be recurring monthly costs, or they might be charged for each transaction.

Not every provider will assess all these fees; some might include everything in their advertised rate. The key for business owners is to ask about all the possible fees to get the full picture of what you'll be paying before you pick a service.

How to Keep Your Payment Processing Fees Low

Card processing fees are inevitable. But that doesn’t mean your current rate is.

Your processing fees are negotiable up to a certain point. However, if your goal is to reduce the overall cost of processing, there are some simple ways to do this:

Tip

Negotiate Fees With Your Payment Processor

Just because you’ve settled on a payment processor doesn’t mean you’re stuck with them forever. Shop around and explore different fee structures to see which works best for your business. If you’re asked to sign a 6- or 12-month contract, try to negotiate better terms once it comes time to renew your agreement, and don’t be afraid to get your current provider to price-match a better quote.

Tip

Incentivize In-Person Sales

Card-not-present transactions are responsible for up to 80% of all reported fraud. Part of shopping around for better-suited service providers and better rates will depend on your overall fraud rate. Although CNP transactions will continue to be a force for any multichannel business, including additional incentives for in-store shoppers could help lower your exposure to CNP fraud.

Tip

Implement Fraud Best Practices

To prevent your business from being shifted into higher-risk pricing tiers (when possible), you must limit your exposure to criminal fraud. While there is no such thing as a “one-size fits all” solution to fraud nowadays, you can dramatically reduce your overall risk with a combination of effective fraud tools at checkout. In general, the more data points you have, the more secure each transaction will be, which means lower fraud risks for your payment processor and lower fees for you.

Tip

Keep Chargebacks At Bay

The lower your chargeback ratio, the lower your fees. To qualify for the best rates, you’ll need to be eligible for standard, low-risk payment processing services. To do so, you should ideally keep your chargeback-to-transaction ratio under 0.5%. This means adopting chargeback prevention best practices, and deploying tools like chargeback alerts and network inquiries to stop disputes before they progress to chargebacks.

Tip

Consider Which Cards You’re Willing to Accept

Unless your payment processor offers a flat-rate or tiered fee structure, your payment processing costs are going to vary from card brand to card brand. For example, luxury American Express cards, like the American Express Platinum or Gold cards, are typically much more expensive to accept than run-of-the-milll Visa- or Mastercard-branded cards. Refusing these cards can be risky, though, and may cost you sales in the long run.

Did You Know?

There are many well-known companies that use selective card acceptance to cut down on processing fees. If you shop at Costco, for example, you may notice that they only accept Visa-branded cards. That’s because Visa, in exchange for this exclusive arrangement, charges the warehouse giant just 0.4% per transaction, allowing Costco to keep prices low for its members.

Processing Fees: Just One Piece of the Puzzle

Payment processing fees are a significant cost of accepting credit cards. But, they’re not the only costs you’ll encounter.

Controlling loss is crucial here. You’ll be penalized for excessive chargebacks, so it’s vital that you prioritize this issue. To fight both criminal fraud and illegitimate chargebacks, you’ll need a comprehensive fraud management strategy that addresses both concerns at once.
