What is a Merchant Account Monthly Minimum Fee?

A merchant account monthly minimum fee is a charge that some payment processors impose when a merchant’s total processing fees for the month fall below a predetermined threshold. Rather than being an additional fee on top of regular processing costs, the monthly minimum is a guarantee that the processor will receive at least a certain amount of fee revenue each month from the merchant’s account. If the merchant’s actual processing fees exceed the minimum, no additional charge applies. If the fees fall short, the merchant pays the difference. In 2026, monthly minimums are still common among traditional merchant account providers, though many modern processors have eliminated them entirely.

How Monthly Minimum Fees Work

A monthly minimum fee is typically set between $15 and $25, though it can vary by processor and agreement. The fee applies to the processor’s markup portion of your processing costs—not to the total amount you pay including interchange fees and network assessments. For example, if your monthly minimum is $25 and your processor’s markup fees for the month total $18, you would be charged an additional $7 to bring the total up to $25. If your markup fees for the month total $30 or more, the monthly minimum does not apply.

It is important to understand that the monthly minimum is not an extra fee charged on top of your processing costs. It is the minimum amount of processing fees the processor expects to collect from your account each month. The additional charge only applies during months when your actual fees do not reach the threshold—typically during slow months or if your business is seasonal.

Impact on Small and Seasonal Businesses

Monthly minimum fees have the greatest impact on small businesses with low transaction volumes and seasonal businesses that experience significant fluctuations in sales throughout the year. For a business that processes very few card transactions during certain months—such as a seasonal retailer, a new startup that is still building its customer base, or a business that primarily handles cash transactions—the monthly minimum can become a noticeable fixed cost that applies regardless of actual sales activity.

For example, a small business that only processes $500 in card transactions during a slow month might generate only $10 to $15 in processor markup fees. If the monthly minimum is $25, the business would pay an additional $10 to $15 to meet the minimum. While these amounts are relatively small, they add up over time and represent an expense that does not correspond to actual processing activity.

Avoiding or Minimizing Monthly Minimums

In 2026, many payment processors and payment facilitators—including popular platforms like Square, Stripe, and PayPal—do not charge monthly minimum fees. These providers use pay-as-you-go pricing models where merchants only pay fees on the transactions they actually process, with no minimum thresholds or monthly charges. This makes them particularly attractive for small businesses, startups, and seasonal operations that cannot guarantee consistent monthly processing volumes.

For businesses that choose a traditional merchant account with a monthly minimum, it is worth negotiating the terms. Some processors will lower or waive the monthly minimum for merchants who commit to a certain monthly volume or who have a strong processing history. Merchants should also compare the total cost of a traditional merchant account with a monthly minimum against the per-transaction costs of pay-as-you-go processors, as higher-volume businesses often find that the traditional account with a monthly minimum still provides lower overall costs due to more competitive per-transaction rates and interchange-plus pricing.

About The Author

Phillip Parker

CPO Creator & Founder

Since 2009, I have researched over 1,000 merchant services providers and published hundreds of payment education-related articles. This work has received national recognition, and my expertise in payments is regularly sought by large media outlets such as CNN, MSN, and INC Magazine, among dozens of others.

Shortly after graduating from college, I was recruited into a sales role with a credit card processor. Only later did I realize that the so-called "training" centered on selling expensive processing agreements... layered with hidden fees and long-term contracts. In my earliest transactions, I unknowingly steered friends and family into costly arrangements after they trusted my recommendation. When I fully understood the structure of what I had been selling, I resigned immediately and committed myself to exposing those practices. That commitment became the foundation of this website.
