From bank fee schedules that read like a foreign language to payment card fee structures riddled with variability, many organizations find themselves flying blind when it comes to managing their payment costs. And while the complexity might seem like a good reason to push off a deep dive, the reality is this: ignoring your fees is likely costing you—significantly.

In a recent webinar hosted by Strategic Treasurer and Optimized Payments, industry experts broke down the intricacies of modern fee structures and provided actionable advice on how finance and payments leaders can regain control.

The Complexity of Fees Is Not an Accident

Whether you’re looking at bank fees or card payment fees, one of the biggest barriers to visibility is inconsistency in how fees are defined and reported. On the card side, a single transaction might carry multiple fee layers: interchange fees paid to the issuing bank, processor fees paid to the acquiring bank, and network fees from brands like Visa and Mastercard. Each of these is calculated differently and reported inconsistently across processors.

For many merchants, this means receiving a jumble of reports—none of which align. As Tom Wrigley, Payments Consultant at Optimized Payments, explained: “It’s really hard to tell what fees are coming from where and how much money is coming in and out.” Without normalization, trying to analyze fee data is like trying to read three different languages at once.

Bank fees aren’t any better. With more than 2,500 unique codes and pricing models in the U.S. alone, even seasoned treasury professionals can struggle to decipher their statements. These documents are full of figures, acronyms, and line items—many of which change without warning. A fee that made sense in last quarter’s report might look completely different in this month’s due to a quiet update in service descriptions or changes in AFP code usage.

Interchange Fees: The Largest and Least Understood Piece of the Puzzle

Interchange fees typically account for 90–95% of a merchant’s card acceptance costs. These fees go straight to the issuing bank and fund cardholder benefits like fraud protection and rewards programs. For example, when a customer earns 3% cash back at a restaurant, that perk is funded by the merchant through interchange.

In the U.S., interchange rates are among the highest in the developed world, largely due to limited regulatory intervention. In contrast, regions like the EU and Australia impose strict caps on these fees.

Not all cards are created equal. A traditional Visa credit card might carry an interchange rate of around 1.89%, while a premium Visa Signature card can reach 2.5%. Merchants can’t control what type of card a customer uses, and they can’t reject higher-cost cards at the point of sale, making this a persistent challenge.

Other uncontrollable factors include merchant category code (MCC), transaction method (card-present vs. card-not-present), and whether the transaction is one-time or recurring. However, there are areas where proactive management can make a difference.

Where You Can Make an Impact

While many fee drivers are out of a merchant’s control, others are directly influenced by internal practices and processor capabilities.

Downgrades, for example, are triggered when required data isn’t passed properly with a transaction—leading to a higher interchange rate. Ensuring the right data fields are populated (especially for commercial cards using Level 2 and 3 data) can prevent costly downgrades and reduce overall effective rates.

Routing debit transactions to lower-cost networks using PIN and PINless strategies is another powerful lever—if your processor supports it. Some processors offer robust routing options, while others don’t prioritize cost efficiency in their configurations.

Tokenization also plays a growing role. Visa, for instance, now offers interchange incentives for card-not-present transactions that are tokenized—a practice that not only improves security but can lower costs for qualifying merchants.

The Myth of Set-and-Forget Bank Fees

On the banking side, many organizations assume their fees are fixed or that their relationship manager will proactively notify them of changes. In reality, this passive approach often leads to unnecessary spend.

Kristen Safali, Director of Product Development and Analytics at Strategic Treasurer, shared that based on their decade of bank fee analysis, natural cost inflation averages around 7% annually. But that’s just the baseline. An additional 7% often stems from unused services, duplicate charges, and outdated products that no longer serve the business.

For example, it’s common to find fees for accounts that were supposed to be closed years ago, legacy fraud tools that have long been replaced, or reporting subscriptions that are now available through portals at no extra cost. Left unchecked, these small charges accumulate quickly—sometimes totaling tens of thousands of dollars per year.

“After we conduct a fee review,” Safali explained, “the average client ends up removing about 20 line items—just catching simple things like paper statements, faxes, or dormant accounts.”

The Hidden Cost of Doing Nothing

During the session, the panel shared aggregated data showing that organizations who don’t actively manage their fees often see a 6.8% “cost of inaction.” That figure includes both inflationary creep and inefficiencies like the ones above.

Stefan Ireland, Senior Director at Strategic Treasurer, summed it up well: “If you pay $200,000 in gross bank fees, that’s $16,000 a year in potential overpayment. And it’s not your bank’s fault—it’s just the way the system works if you’re not looking closely.”

The key message? You’re paying fees either way. The only real question is whether you’re paying more than you should.

Why Excel Isn’t Enough Anymore

For many companies, fee analysis still happens in Excel. And while it’s better than doing nothing, it has real limitations. Each provider structures their data differently. One might use AFP code 430 to describe a wire fee, while another uses 999 or a custom label. This makes it almost impossible to build clean benchmarks or spot discrepancies.

Analytics platforms are designed to normalize disparate data sources—standardizing interchange, processor, and acquirer fees into a single, digestible view. They allow teams to filter by location, payment method, transaction type, or processor, revealing trends and inefficiencies that would otherwise stay hidden.

More importantly, analytics tools give you the credibility and clarity to communicate with stakeholders—from your finance team to your bank partners. “It’s not just about managing fees,” Wrigley added, “It’s about being able to communicate those fees and the trends behind them to upper management.”

Empower Your Partnerships With Insight

Fee analysis isn’t about confrontation—it’s about conversation. Whether it’s your processor, acquiring bank, or treasury partner, informed dialogue is key to optimization.

As Stefan emphasized, banks are often more responsive when they know you’re paying attention. “If we see that you are tracking your fees, then maybe your banker is going to be more proactive in terms of communicating upcoming changes.”

Having a firm grasp of your fee data also helps you understand your RAROC (risk-adjusted return on capital)—which influences the rates and incentives your bank might offer. If you don’t know how your bank perceives your risk profile, you could be leaving negotiating power on the table.

Final Thoughts: Complexity Is Inevitable. Inaction Is Optional.

In today’s environment, where fees evolve constantly and each new product rollout comes with hidden costs, the only truly costly choice is inaction. Whether it’s card acceptance or treasury services, fee management can no longer be treated as an annual check-in.

By investing time—or better yet, tools—into understanding and managing your fee structures, you’re not just saving money. You’re building resilience, deepening partnerships, and creating operational clarity in one of the most opaque areas of your business.

So take the next step. Whether that means reviewing your Excel sheets with fresh eyes, asking your processor for detailed reporting, or exploring a payment analytics platform, what matters most is that you do something.

Because when it comes to fee management, waiting quietly might be the most expensive decision you make all year.
