What Are Per-Transaction Fees?

A per-transaction fee is an expense a business must pay each time it processes an electronic payment for a customer transaction. Per-transaction fees vary across service providers, typically costing merchants from 0.5% to 5% of the transaction amount plus certain fixed fees.

How Per-Transaction Fees Work

Per-transaction fees are required of the merchant from a few different entities in a transaction. Merchants partner with merchant acquiring banks to facilitate all of the communications in an electronic payment transaction.

Merchants also set up a merchant account with the acquirer, which serves as the merchant’s primary deposit account for funds from each transaction. A merchant who receives a lot of electronic payments will rely heavily on the merchant acquiring bank, making the terms of the merchant account agreement an important factor for a merchant.

Components of Per-Transaction Fees

Merchants pay a variety of fees related to the acceptance of electronic payments. Some fees will vary while others are fixed. Merchants have a wide range of acquiring banks they can partner with for electronic payment services. Each acquirer has different fee structures and service capabilities allowing merchants to choose the acquirer that is best for them.

The second component of a per-transaction fee is the fee paid to the network processing company. Merchants establish the types of branded cards they can accept at their store based on the processing network of their merchant acquiring bank. Payment card companies such as MasterCard, Visa, Discover, or American Express each have their per-transaction fees that will be charged to the merchant in a transaction. Payment card company fees, also called wholesale fees, are usually a fixed fee per transaction. Some acquirers may be able to negotiate lower wholesale fees through network relationships with processors.

Acquirer and processor fees are the main components of a comprehensive per-transaction fee. In some cases, other fees for a merchant may also apply. One added cost merchants might encounter is a terminal fee which is a per-transaction fee charged to a terminal provider such as Square for the use of a terminal in an electronic payment card transaction.

Per-transaction fees are the reason why some merchants impose a minimum that customers must spend if they want to pay with a credit or debit card. For example, merchants may set a $5 or $10 minimum for credit card and debit card transactions. Smaller merchants who are less able to absorb excess card fees are more likely to impose these minimums.

Merchant Account Statements

Acquirers will detail a merchant’s total monthly costs and transaction activities in a monthly statement. Generally, service provider transaction fees will be delineated in one of three categories: interchange, tiered, or subscription.

The interchange section lists the payment card company fees and service provider fees separately on the merchant’s monthly statement. The tiered section assesses different fees based on the transaction type, such as in-person versus online. Subscription fees are also assessed on a monthly or annual basis.

The Bottom Line

Per-transaction fees are charged to merchants, not consumers, but you may be affected by these fees if the merchant adjusts prices to recoup their expenses. Merchants, especially smaller businesses, may also set minimum purchase amounts if you are using a credit card so that they do not lose money on a transaction.
