What network assessment fees actually are
On top of interchange (which goes to the issuing bank) and processor markup (which goes to your acquirer), every transaction pays a third bucket of fees called "assessments." These go to the card networks themselves — Visa, Mastercard, Amex, Discover. They fund the networks' operations, fraud monitoring, brand marketing, and profit.
Assessments are small per-transaction but they add up. On a $500k/mo merchant running standard CNP mix, network fees run $1,500-2,500/mo. Over a year, that's $18-30k going directly to the networks — separate from interchange, separate from processor markup.
Most merchants never see these broken out. Their statement says "Fees" or "Processing charges" as a single line. That line bundles interchange + assessments + processor markup together, which makes it impossible to know which component to negotiate.
The Visa-specific fees
Visa Assessment Fee (Acquirer Service Fee)
0.14% of every transaction in volume. Called the Acquirer Service Fee internally. Changes periodically — was 0.13% until 2019, raised to 0.14% in 2020. Applies to all Visa volume regardless of card type or transaction channel.
Visa APF (Acquirer Processing Fee)
$0.0195 per authorized transaction. Flat, per-transaction, regardless of dollar amount. Hammers low-ticket merchants — on a $5 transaction it's effectively 0.39% added to the bill.
Visa Acquirer Fixed Fee
$0.0025 per transaction. Added to APF. Small individually, real at volume.
Visa International Service Assessment (ISA)
When a US merchant processes a foreign-issued Visa card. Two-part: ISA assessment of 0.8% (domestic currency settlement) or 1.0% (cross-currency settlement). This is the cross-border fee everyone talks about.
The Mastercard-specific fees
Mastercard Assessment
0.1375% of every transaction's volume. Slightly lower than Visa's 0.14%. Applies uniformly.
Mastercard NABU (Network Access Brand Usage)
$0.0195-0.02 per transaction depending on program. Effectively Mastercard's equivalent of Visa APF.
Mastercard Cross-Border Fee
0.8-1.0% on international transactions. Similar structure to Visa ISA.
Mastercard AVS Fee
$0.0025 per AVS-checked transaction. Most CNP merchants run AVS on every transaction, so this is effectively a per-transaction fee. Small but universal.
Amex and Discover
Amex operates on a different model. Most merchants accept Amex through OptBlue (where the processor acts as a middleman) with pricing 20-60 bps higher than Visa/MC. The network fee component is ~0.15% assessment plus per-transaction fees that mirror Visa/MC. Direct Amex merchants (enterprise) pay lower.
Discover operates most similarly to Visa/MC. 0.13% assessment, per-transaction fee around $0.0185. Discover volume is typically <5% of total for most merchants so the absolute dollars are small.
Why this calculator exists
Processor statements obscure these fees. A "Fees" line that says $5,400 on a $500k merchant tells you nothing. This calculator estimates what the real network pass-through should be, given your volume and mix. Subtract the calculator's total from your actual processor statement's fees line. What's left is interchange + processor markup. Cross-reference with our interchange-plus breakdown calculator to isolate markup.
Where processors sneak margin
Inflated assessment passthrough
Some processors charge "assessments" at 0.18% instead of the true 0.14% Visa rate. The extra 4 bps is pure markup disguised as passthrough. On a $500k merchant that's $200/mo hidden in plain sight. Audit your statement against published network rates to catch this.
"NABU and APF and Assessment" as a single bundled fee
When the statement rolls multiple network fees into a single line with a made-up name ("Network Service Charge"), the merchant can't verify any component. Common at lower-tier ISOs.
Cross-border fees when no cross-border occurred
A US-issued card with an international billing address sometimes triggers cross-border fee classification even though the card is US-issued. Processors pass through what the network bills; networks occasionally err. Audit if your international % on the statement exceeds what your customer data says is international.
"Regulatory compliance fees"
Monthly flat-dollar charges for "PCI compliance," "regulatory compliance," "industry fees" that are not pass-through. These are pure processor revenue. Most are $3-30/mo and negotiable.
What to do with this total
Compare to your statement. If your statement's network fees match within 5%, your processor is honest. If your statement is 10%+ higher, there's padding. Call your rep, ask for a line-item breakdown, and renegotiate.
For multi-brand operators, run this calculator per brand. Network fees as a % of volume should be roughly consistent across brands (they're volume-based, not risk-based). If one brand has materially higher network fees, that processor is padding the passthroughs.
FAQ
Are network assessment fees negotiable?
No. Visa and Mastercard set them and they apply to every acquirer equally. Anyone claiming to negotiate "lower assessments" is either confused or lying.
Do these fees go to the processor?
No. They go to the networks. The processor is just a pass-through — collects from you, remits to Visa/MC/etc.
Why do I see different fees on different processors for the same volume?
Because some processors bundle or inflate the pass-through. The true fees should be the same across any compliant processor.
Are there fees I'm not seeing?
Likely yes. Visa has 20+ distinct network fees; this calculator captures the big ones. Tokenization fees, digital wallet fees (Apple Pay adds 0.15% visible; Google Pay 0%), fraud services, and regulatory fees add up.
Do all these fees apply to refunds?
Some are refunded back, some aren't. Per-transaction fees (APF, NABU) are not refunded on refunded transactions — you pay the fee on both the original and the refund. Percentage assessments are typically credited on refunds.
