TL;DR

On the Visa USA Interchange Reimbursement Fees schedule effective October 24, 2026, card-not-present consumer credit costs roughly 0.3 to 0.6 percentage points more than the same card in person, and your processor's markup, downgrades and any risk fees come on top. Many online sellers on flat-rate plans pay a single rate such as Stripe's 2.9 percent plus 30 cents on every card-not-present charge and never see the breakdown. The fix is an interchange-plus statement audit, AVS and CVV hygiene, level 2 data on the B2B portion of your volume, and a flat per-transaction processor markup instead of a percentage spread.

What this actually is

Card-not-present surcharges are the cumulative extra fees you pay on transactions where the card is not physically swiped, dipped, or tapped. The premium has three layers, and each layer is set by a different counterparty in the payment chain.

The first layer is interchange. Visa and Mastercard publish higher interchange rates for keyed, e-commerce, and mail-order transactions, which carry more fraud risk for the card-issuing bank. On the Visa USA Interchange Reimbursement Fees schedule effective October 24, 2026, a standard consumer credit card costs 1.89 percent plus 10 cents in the card-not-present Product 1 category, against 1.43 to 1.51 percent plus 10 cents for an in-person retail sale.

The second layer is processor markup. On a tiered plan, the processor classifies CNP transactions as mid-qualified or non-qualified and adds its own surcharge on top of interchange. The merchant rarely sees the underlying interchange cost, only the marked-up rate. Stripe charges 2.9 percent plus 30 cents online, and Square charges 2.9 percent plus 30 cents online on its paid plans and API, or 3.3 percent plus 30 cents on its Free plan (prices checked Oct 2026).

The third layer is downgrade risk. A CNP transaction that misses AVS, CVV, electronic clearing, or settlement timing rules can fail to qualify for its normal category. On Visa's October 2026 schedule, a consumer credit sale that does not qualify at all costs 3.15 percent plus 10 cents (Non-Qualified Consumer Credit). Some downgrades are silent: the transaction approves and settles, but at a higher rate that surfaces only on the statement weeks later.

A card-not-present surcharge is the extra fee charged by the card networks and the processor for transactions where the card is not physically swiped, dipped, or tapped at a terminal.

How it works under the hood

A card-not-present transaction lives or dies on the data your gateway submits. The interchange category, and therefore the rate, is determined by the data fields that flow through authorization and clearing.

The flow:

  1. Customer enters card data on your checkout page, mobile app, or via phone to your agent.
  2. Your gateway sends an authorization request to the acquirer, which routes it to Visa or Mastercard.
  3. The network forwards the auth to the issuing bank, which approves or declines based on available funds, fraud signals, and AVS or CVV match.
  4. Your batch settles after it closes, with clearing data attached to each transaction.
  5. The network applies an interchange category based on auth data, clearing data, merchant category code, and timing.
  6. Your acquirer charges you that interchange plus its markup, plus any network assessments, on the next monthly statement.

The CNP premium is locked in at step 5. On Visa's published interchange schedule effective October 24, 2026, the card-not-present Product 1 rates for consumer credit are 1.89 percent plus 10 cents on standard cards, 2.04 percent on Traditional Rewards, 2.05 percent on Visa Signature, 2.50 percent on Signature Preferred and up to 2.60 percent on Visa Infinite, all plus 10 cents. Visa lists card-not-present incentives of 0.05 to 0.15 points off for qualifying EMV token and Digital Commerce Authentication Program (DCAP) transactions. A consumer credit sale that fails to qualify drops to Non-Qualified Consumer Credit at 3.15 percent plus 10 cents.

Mastercard publishes its own U.S. interchange schedule with a similar split between in-person and card-not-present sales. Its site blocked our checker in Nov 2026, so we do not quote its rates here; your statement lists the Mastercard categories you actually paid.

On Visa's schedule, the gap between the in-person retail rate for a standard card (1.43 to 1.51 percent plus 10 cents) and its online Product 1 rate (1.89 percent plus 10 cents) is the network-level premium for selling online: roughly 0.4 points.

Above interchange, Visa and Mastercard charge your processor their own network fees, often shown as assessments and per-transaction network fees. These are not on Visa's public interchange schedule, so ask your processor to list each network fee it passes through and its rate. They should be the same pass-through for every merchant. Anything else above interchange and those network fees is processor margin.

Operator noteThe 1.89 percent rate is the floor for standard consumer credit online, not the ceiling. Premium cards carry higher card-not-present rates on Visa's schedule, up to 2.60 percent plus 10 cents for Visa Infinite. Your effective CNP interchange is a blended weighted average across the card mix, not a single number.

Where it goes wrong for operators

Five patterns account for the majority of CNP overcharges in the field.

Tiered pricing hides the markup. Tiered plans label CNP transactions as 'mid-qualified' or 'non-qualified' and charge a single marked-up rate. A transaction that runs at 1.89 percent interchange under interchange-plus might appear on a tiered statement as a 2.50 percent mid-qualified charge. That 61 basis point gap is processor margin, not network cost. On $300,000 monthly CNP volume, that is $1,830 per month, or $21,960 per year. Flat-rate pricing hides the split too. Our ranking engine, which assumes a typical card mix, puts Stripe's standard online pricing at an effective 3.50 percent at $250K a month, against 2.45 percent for Helcim's interchange-plus online pricing (prices checked Oct 2026).

AVS and CVV mismatches downgrade transactions. If your gateway does not pass full address verification data and the CVV result code, a transaction can fail to qualify for its normal card-not-present category. If it falls from Visa's 1.89 percent Product 1 rate to the 3.15 percent Non-Qualified Consumer Credit rate, that is 1.26 points. On $200,000 monthly volume with 10 percent of it downgraded that way, that is $252 per month, or $3,024 per year, in avoidable cost.

Late settlement costs you the qualified rate. Visa's interchange programs have timeliness requirements, and batches that settle late can fail to qualify. If a $50,000 batch fell from 1.89 percent to the 3.15 percent non-qualified rate, the extra cost would be $630. Billing engines that delay capture for retry logic are one place to look.

level 2 and level 3 data is left on the table. B2B and government commercial cards can qualify for lower interchange when extra transaction data flows through clearing. On Visa's October 2026 schedule, corporate and purchasing cards cost 2.70 percent plus 10 cents card-not-present, and 1.75 percent plus 10 cents in the Commercial Product 3 program, which needs that extra data. Most e-commerce gateways do not submit those fields by default. A merchant with 30 percent corporate and purchasing card volume on $200,000 monthly that qualified all of it for the lower rate would save about $570 per month.

Surcharging compliance gets misread. Merchants who pass a credit card surcharge to customers must follow card network rules and state law. Under the Visa Core Rules, you must notify your acquirer in writing at least 30 days before you announce or start a surcharge, keep it within your merchant discount rate for Visa credit cards and never above 3 percent, and surcharge credit only. For online sales, Visa requires the notice on the first page that references the card brands you accept and on the checkout page, in at least 10-point type, and the customer must be able to cancel after seeing the surcharge. Mastercard sets its own cap, which we could not verify, so ask your acquirer. Debit and prepaid cards cannot be surcharged under Visa's rules. Some states limit or prohibit surcharging, so check your state's current rules. Our credit card surcharging guide covers the full rules and which processors support it.

Watch outIf you surcharge a debit or prepaid card, the card-issuing bank can recover the surcharge through Visa's compliance process, and your acquirer can act under your contract. Surcharge logic must check the card type before the sale and apply only to credit. Stax, for example, says it processes Apple Pay and Google Pay sales without a surcharge because it cannot check the card type first. Test your setup before launch.

On tiered pricing, the gap between your rate and the underlying interchange is processor margin disguised as a tier label.

Worked example with real numbers

Consider a hypothetical SaaS company billing $200,000 in monthly volume across 500 transactions, average ticket of $400, on a flat rate of 2.9 percent plus 30 cents per transaction. That matches Stripe's standard online rate, though Stripe adds 1.5 percent for international cards and 0.5 percent for manually entered cards. Card mix is 70 percent consumer credit, 20 percent corporate credit, 10 percent debit. All transactions are card-not-present, processed through a hosted checkout integration.

Current cost on flat-rate:

  • Volume fee: $200,000 times 2.9 percent equals $5,800
  • Per-transaction fee: 500 times $0.30 equals $150
  • Monthly total: $5,950
  • Effective rate: 2.98 percent

Estimated true cost of acceptance (Visa rates from the October 2026 interchange schedule; card counts follow the volume split):

  • Consumer credit (70 percent of volume, 350 sales): $140,000 at an assumed blend of 2.10 percent plus 10 cents across standard and premium cards, whose Product 1 rates run 1.89 to 2.60 percent, equals $2,975
  • Corporate credit (20 percent, 100 sales): $40,000 at Commercial Card Not Present of 2.70 percent plus 10 cents equals $1,090
  • Debit (10 percent, 50 sales): $20,000 at regulated debit of 0.05 percent plus 22 cents (21 cents plus 1 cent for qualifying issuers) equals $21
  • Total interchange: $4,086
  • Network fees: we assume 0.15 percent of volume, $300, for the example; ask your processor for the actual rates it passes through
  • Estimated cost of acceptance: $4,386

Cost on interchange-plus at 0.30 percent plus 10 cents (an example markup, not a quote):

  • Interchange plus network fees: $4,386
  • Processor markup: 0.30 percent times $200,000 equals $600, plus 500 times $0.10 equals $50, total $650
  • Monthly total: $5,036
  • Effective rate: 2.52 percent

Savings: $914 per month, or $10,968 per year. Over a 60-month review window, that is about $54,840.

If the corporate card portion qualified for Visa's Commercial Product 3 rate of 1.75 percent plus 10 cents instead of 2.70 percent, that is 0.95 points on $40,000 in monthly commercial volume: another $380 per month, or $4,560 per year, on top of the interchange-plus savings.

Visa's October 2026 schedule also lists card-not-present incentives of 0.05 to 0.15 points for qualifying EMV token and DCAP transactions. If your authentication setup qualified the $140,000 of consumer credit for the 0.10 point incentive, that is $140 a month. Authentication can also shift fraud chargeback liability to the issuer; what that saves depends on your dispute history.

Hypothetical resultThe SaaS merchant above pays an effective 2.98 percent on flat-rate. Its estimated interchange plus network fees come to about 2.19 percent. The gap, about $1,564 per month, is what the flat-rate provider keeps for processing, routing and a hosted checkout. Across a 36-month review window, that is about $56,300. Interchange-plus pricing shows the same volume costing about 2.52 percent in total, including the processor's own 30 basis point markup, debit transactions, and per-transaction fees.

Operator playbook

  1. Pull your last three statements and flag every line item labeled non-qualified, mid-qualified, EIRF, Standard, or any tier label. These are your downgraded CNP transactions. Sum the dollar volume in each category and calculate what the same volume would cost at Visa's published Product 1 rate for that card type.
  2. Calculate your effective CNP rate. Divide total CNP fees, including assessments and processor surcharges, by total CNP volume. Compare it with the interchange categories listed on your statement to see how much sits above network cost. Your statement is the authoritative source.
  3. Request an interchange-plus quote from at least three processors. Ask each for a sample statement that itemizes interchange, assessments, and the processor markup as separate line items. Walk away from anyone who refuses to provide an itemized statement or who insists on tiered pricing for CNP volume.
  4. Audit AVS and CVV pass rates in your gateway dashboard. Low pass rates on domestic volume point to downgrades. Most modern gateways expose this metric in a transactions report. Fix gateway configuration before negotiating rate.
  5. Enable level 2 and level 3 data submission if you process B2B or government cards. Confirm with your gateway and processor that the line-item, tax amount, and customer code fields are populated and flowing through clearing. On Visa's October 2026 schedule, Commercial Product 3 costs 1.75 percent plus 10 cents against 2.70 percent plus 10 cents for standard commercial card-not-present sales.
  6. Negotiate a flat per-transaction markup, not a percentage spread, on the processor margin. A flat 10 cents per transaction at $200,000 monthly volume across 500 transactions is materially cheaper than 0.30 percent plus 5 cents on the same volume.
  7. Reject long early-termination terms. Some interchange-plus providers publish no contract at all; Helcim is one. Ask for month-to-month or a short term with no liquidated damages. A long term locks in future rate increases for the duration.
  8. Re-quote every 18 to 24 months. Effective rates drift up after onboarding through silent fee increases buried in monthly notices, new network fees passed at a markup, and category drift in your card mix. Compare the current effective rate to the rate at signing and renegotiate before the gap exceeds 25 basis points.
