A FANF fee is Visa's Fixed Acquirer Network Fee: a monthly network fee Visa bills the acquiring bank, which your processor then usually passes through as a line on your merchant statement. It is not interchange, and it is not processor markup. Visa's November 2025 proposed merchant settlement names FANF as a network fee assessed to acquirers, separate from interchange (Visa Inc. Form 8-K Exhibit 99.1, 10 Nov 2025). How large the line is depends on your Visa volume, how many outlets sit under the same taxpayer ID, and whether you take cards in person or not. You cannot negotiate the Visa table away. You can insist the fee is billed at cost, labeled as Visa, and counted when you compute your effective rate.
Cards are how most U.S. noncash payments happen. The Federal Reserve's 2025 payments study found 79 percent of noncash payments by number in 2024 were cards (Federal Reserve FRPS, 1 Jul 2026). Network fees sit on that rail. FANF is one of them.
Where FANF sits in the three layers
Every card fee you pay falls into one of three buckets. Mixing them up is how a $20 monthly line either looks like a scandal or disappears into a blended rate.
Interchange is the transfer fee between the merchant's bank and the card-issuing bank. Visa's public U.S. interchange tables, dated 18 April 2026, are explicit: merchants do not pay interchange reimbursement fees; they pay a merchant discount to their financial institution (Visa USA Interchange Reimbursement Fees, 18 Apr 2026). U.S. banks collected nearly $66 billion in those interchange fees in 2025 (Federal Reserve Bank of St. Louis, 9 Apr 2026). That is the large layer. FANF is not it.
Assessments (and other network dues) are what the card brands charge for use of the network. They are pass-through, like interchange. FANF lives here: a Visa fee, billed to the acquirer. See what assessment fees are if you want the family definition.
Processor markup is the only layer anyone competes on. Visa's fiscal 2025 10-K states that Visa sets fees to acquirers independently from any fees acquirers may charge sellers, and that acquiring clients set the merchant discount rate (Visa Inc. Form 10-K, fiscal year ended 30 Sep 2025). A provider can pass FANF through at cost, bundle it, or pad it. The first is honest. The other two are why you read the line.
Typical processing fees overall are often described as 1.5 percent to 3.5 percent of the transaction plus a per-item fee (U.S. Chamber of Commerce, "How to Calculate Credit Card Processing Fees"). Treat that as a range of total cost, not as Relyon's rate, and not as FANF. FANF is a slice of the assessment layer, not the whole bill.
Visa put FANF in place as a fixed acquirer fee. In its fiscal 2012 10-K, Visa described an acquirer pricing restructure that implemented a fixed fee and lowered some variable per-transaction fees, including the Fixed Acquirer Network Fee (Visa Inc. Form 10-K, fiscal year ended 30 Sep 2012). The name is doing real work: this is a monthly network access charge, not another interchange category on each swipe.
What actually sets the dollar amount
Visa does not publish the current FANF schedule on its public merchant site. The U.S. merchant fees page hosts interchange tables and surcharge rules; FANF is billed from Visa's acquirer fee tables, which your processor holds. Do not trust a blog's dollar grid as "what Visa charges this year." Ask for the table they used.
What you can say without inventing a schedule:
- It is monthly, not a per-transaction percentage. A slow week does not prorate it the way interchange does.
- Volume matters. More Visa sales can move you up a tier, especially if a large share is card-not-present.
- Outlets matter. Visa looks at locations under the same taxpayer identification number, not only at a single merchant ID. Two shops and a seasonal kiosk under one EIN are one FANF picture, not three unrelated ones.
- How you accept cards matters. Card-present volume, card-not-present volume, and merchant category can land in different buckets. Keyed, e-commerce, and unattended traffic often prices differently from tapped and dipped traffic.
- The mix can stack. A store that rings the register and also takes phone orders can see more than one FANF component in the same month.
That is why the line moves even when "your rate" did not. The processor's markup can sit still while Visa's table, applied to this month's volume and outlets, prints a different number.
How FANF shows up on a statement
On a clean interchange-plus statement, FANF should be its own Visa-branded line: "Visa FANF," "Fixed Acquirer Network Fee," "Visa Network Fee CP," "Visa Network Fee CNP," or a close variant. How to read your merchant statement is the walkthrough for finding it among the other network lines.
On a tiered, flat-rate, or bundled statement, FANF is often swallowed. You still pay it. You just cannot see it. That is not a reason to prefer blended pricing; it is a reason to demand an as-billed view when you compare offers.
Two audit tells:
- The label does not say Visa. "Network access," "regulatory," or "brand fee" with no scheme name is a blended bucket. Ask them to split Visa FANF from Mastercard and Discover dues, and from their own markup.
- The amount never changes. True FANF tracks activity. A perfectly flat line for a year of growing volume is either a floor they chose to bill, or it is not FANF.
If you operate under more than one MID, confirm they are rolling locations to the taxpayer ID the way Visa does. Split MIDs do not create split FANF if they share an EIN.
What FANF does to effective rate (illustrative)
Effective rate is still the only comparison number: total fees divided by card volume. FANF belongs in the numerator with interchange, assessments, markup, batch, PCI, and the rest.
Worked example, illustrative only. One month, $40,000 in card volume:
| Line | Amount |
|---|---|
| Interchange and other assessments | $920 |
| Processor markup | $240 |
| FANF | $20 |
| Other monthly (statement, batch, PCI) | $20 |
| Total fees | $1,200 |
| Effective rate | $1,200 ÷ $40,000 = 3.00% |
| FANF's slice of that rate | $20 ÷ $40,000 = 0.05% |
Five basis points will not make or break most shops. It will distort a comparison if one quote itemizes FANF and the other hides it inside "2.70% plus $0.10." Add it back on both sides, or you are not comparing the same bill. On thin-margin, low-ticket volume the monthly floor matters more than the percentage; on high volume the tier steps matter more. Either way, put the actual dollar in the effective-rate formula instead of arguing about the nickname.
What you can change, and what you cannot
You cannot shop FANF the way you shop markup. Visa sets the acquirer fee; the acquirer passes it through. Switching processors does not create a private Visa discount.
What you can do:
- Require pass-through at cost. The test is simple: same taxpayer ID, same outlets, same Visa mix should produce the same FANF at two honest acquirers. If it does not, someone is bundling.
- Keep the legal entity map clean. Extra unused MIDs, leftover seasonal locations, and a second DBA that still reports volume can inflate the outlet count Visa sees. Close what you do not use.
- Know your channel mix. Moving volume from a terminal to a virtual terminal or a website is not "the same rate plus convenience." It can change the FANF bucket. Price the whole stack, not the swipe rate.
- Do not confuse FANF with junk. A PCI program fee, a statement fee, and a monthly minimum are processor products. FANF is a Visa product. Fight the first group on value. Audit the second on the table.
What not to do: treat FANF as proof you are overpaying, or as proof you are not. Overpayment lives in markup, junk fees, and a model that does not fit the mix. FANF is a reason to read the statement, not a reason to panic.
How to audit the line this month
Pull one full statement. Circle every Visa network line. Ask your provider, in writing:
- Which Visa acquirer fee table and effective date did you bill?
- Which taxpayer ID, location count, MCC, and Visa volume did you send?
- Is any of this line your markup, a minimum, or a bundled "network" product?
If they produce the table and the inputs, you can reproduce the fee. If they cannot, you do not have a pass-through; you have a number. For a full as-billed view of the rest of the statement, run the analyzer.
FANF will still be there next month. The job is to keep it in the assessment column, at Visa's cost, and inside the effective rate, so it never masquerades as a rate you were quoted.
FAQ
What is a FANF fee? FANF is Visa's Fixed Acquirer Network Fee, a monthly network fee Visa bills the acquiring bank. Your processor usually passes it through as a statement line. It is not interchange and not processor markup.
Is FANF the same as an assessment fee? It sits in the same family: a card-network charge passed through at cost, not a markup your provider invented. Assessments are usually a small percentage of volume. FANF is a monthly Visa fee whose size depends on volume, outlets, and how you accept cards.
Can I negotiate FANF with my processor? You cannot negotiate the Visa table. You can insist the line is billed at cost, labeled as Visa FANF, and not padded. If two quotes differ on FANF for the same volume and outlets, one of them is not passing it through cleanly.
Why did my FANF change this month? FANF is recomputed from the activity Visa sees: volume, card-present versus card-not-present mix, outlets under the same taxpayer ID, and merchant category. A busier month, a new location, or more keyed and online volume can move the line even if your processor's markup did not change.
Does FANF apply only to credit cards? FANF is a Visa network fee on Visa-branded acceptance your acquirer reports. The exact products and channels in the base live in the acquirer table, not on Visa's public merchant site. Ask which Visa volume they included.
How do I know FANF is billed at cost? On an interchange-plus statement it should appear as its own Visa-branded line, not inside a blended rate. Ask for the Visa acquirer fee table they billed against and match it to your outlets, mix, and volume. If they cannot produce the table, treat the line as unaudited.
