What Are Pass-Through Fees in Processing?
What pass-through fees mean
Pass-through fees are the underlying card-processing costs your provider bills to you at cost, rather than creating them itself. In plain language, these are charges set outside the processor and then passed through to the merchant on the monthly statement.
The two main parts are interchange and card-network assessments. Interchange is set by the card networks and paid to the cardholder’s issuing bank. Assessments and network fees are charged by the card brands themselves, such as Visa, Mastercard, Discover, and American Express. That distinction matters because pass-through fees are generally not the part of pricing a processor can freely change.
What is included in pass-through fees
Interchange is usually the largest pass-through cost. It can vary based on factors like card type, whether the card is present, how the transaction is entered, the business category, and whether required transaction data is submitted correctly. On many statements, interchange appears as many separate line items rather than one simple fee.
Assessments and network fees are the other major pass-through component. These can include brand-level charges applied per transaction, by volume, or for specific network services. Typical examples may include items such as [VERIFY: network assessment fees], [VERIFY: per-transaction network access fees], and other brand charges that change over time.
You may also see related line items that feel similar to pass-through costs but are not always true pass-through items. Statement formatting varies a lot, which is why many businesses struggle to tell what is fixed, what is bundled, and what is negotiable.

Why processors charge pass-through fees
Processors collect these costs because they must pay the banks and card networks involved in moving each transaction. In that sense, pass-through fees are part of the basic plumbing of card acceptance. If your business accepts cards, some version of these costs is typically unavoidable.
The key point is that pass-through fees are largely the same no matter which processor you choose, because the networks and issuing banks set them. What usually differs from one provider to another is the processor’s own markup, plus account fees, gateway charges, and other service-related pricing.
That is why two offers can sound very different while the underlying pass-through costs remain similar. A provider may lower its markup, bundle costs into simplified pricing, or add extra fees, but it usually does not control the core interchange and assessment structure itself.
How pass-through fees appear under different pricing models
With interchange-plus pricing, pass-through fees are separated from the processor’s markup. This is often the clearest structure because you can see the interchange and network costs, then a stated markup added on top, such as [VERIFY: a per-transaction markup] and [VERIFY: a percentage markup]. That visibility makes comparison easier.
With tiered pricing, pass-through costs are grouped into buckets like qualified, mid-qualified, and non-qualified. That can make pricing simpler to read at first, but it also hides the true split between actual pass-through expense and processor markup. A flat-rate model can do something similar by wrapping many underlying costs into one blended price.
If you want to understand which model gives you the clearest view of your real costs, read tiered vs. interchange-plus pricing. For many businesses, transparency matters more than simplicity because hidden bundling can make it harder to spot negotiable charges.
Typical amounts and why they vary
There is no single pass-through fee for every merchant. Interchange categories can differ widely based on card brand, rewards level, business type, acceptance method, and data quality. Assessment and network charges also change from time to time. As a general guide, interchange often ranges from [VERIFY: a low debit-card category] to [VERIFY: a higher premium or card-not-present category], while network assessments are usually much smaller per item but still add up over volume.
What matters more than memorizing any one figure is understanding that pass-through costs are dynamic and transaction-specific. Your statement may show dozens of interchange categories in a single month. It may also include network charges expressed as [VERIFY: a small percentage of volume], [VERIFY: a per-transaction amount], or both.
Because these amounts can change, businesses should verify current schedules before relying on any published figures. If you want a rough way to estimate how processing costs affect your margins, the processing fee calculator can be a useful starting point.
Can pass-through fees be reduced or avoided?
Usually, the rates themselves cannot be negotiated directly with your processor because the core pass-through schedules come from the networks and issuing banks. But that does not mean your total cost is fixed. A business can often reduce how expensive its transactions qualify by improving acceptance practices.
For example, a merchant may lower total costs by:
- Submitting transactions promptly to avoid downgrades
- Using the correct card-present setup when cards are accepted in person
- Making sure address and verification data is captured properly for keyed or online sales
- Routing eligible debit transactions correctly when system settings allow
- Providing enhanced data on qualifying B2B or government purchases
For B2B companies, Level 2 and Level 3 data can sometimes help certain transactions qualify for better interchange treatment when supported by the card type and gateway setup. Learn more in Level 2 & 3 data for B2B savings.
The more negotiable piece is usually your processor’s markup. If your provider charges a higher markup, monthly fee, gateway fee, or added service fee, those are the areas that may be reviewed and negotiated. Looking at your effective cost over time can also help; see what is a good effective rate?.
How RatesNegotiator helps
RatesNegotiator reviews merchant statements to separate true pass-through costs from the provider’s markup and extra fees. That matters because many statements make everything look equally unavoidable when it is not.
A careful review can show whether you are on a transparent pricing model, whether avoidable downgrades may be happening, and whether negotiable charges appear higher than they should be for your business profile. The goal is not to claim that all processing costs can be removed, but to identify which parts are fixed and which parts may be improved.

Frequently Asked Questions
What are pass through fees in credit card processing?
Pass through fees are charges a processor bills to the merchant at cost from the card ecosystem, mainly interchange and network assessments. They are different from the processor’s own markup and service fees.
Are pass-through fees the same with every processor?
The underlying interchange and network charges are generally similar across processors because the card networks and issuing banks set them. What often changes is the processor’s markup and any extra account fees.
Can I negotiate pass through fees?
Usually, the core pass-through schedules themselves are not directly negotiable with your processor. You may still lower total costs by reducing downgrades, improving transaction data, and negotiating the processor markup.
Why do pass-through fees look different on my statement?
Processors format statements in different ways, and some pricing models bundle costs instead of showing them separately. Interchange-plus pricing usually gives the clearest view of true pass-through charges versus markup.
Are there rules about how pass-through fees can be disclosed?
There can be card-network requirements, contract terms, and state-law issues related to disclosures and billing practices. This is general information, not legal advice, and you should confirm current network rules and applicable law with a licensed professional.
