Processing Rates by Volume: What Actually Changes

Why there is no table to publish

Visa states the position in the introduction to its own rate document: merchants do not pay interchange reimbursement fees; merchants pay “merchant discount” to their financial institution. It goes on to say this is an important distinction, because merchants buy a variety of processing services from financial institutions, and all these services may be included in their merchant discount rate, which is typically a percentage rate per transaction. Interchange is therefore an input to your price, published and identical for everyone whose sale lands in the same fee program, while the rest of your rate is set by your provider and is not published anywhere. Any article offering an effective rate for “$50,000 a month” is quoting the second part, which nobody publishes, as if it were the first. Visa's own answer to the question is to contact your financial institution about which interchange rates you are eligible for.

Where volume does appear in the schedule

It appears twice. The first is a ceiling rather than a discount. Visa publishes a Small Merchant Category Volume Maximum of $280,000 in gross Visa consumer credit sales, based on 12 months of Visa system activity ending 30 September 2024, and notes that a small merchant transaction that disqualifies for the Small Merchant Fee Program will be assessed at the next applicable rate. Crossing that line moves you out of a set of programs, not into a better one. The second is at the other extreme. Visa's credit performance threshold criteria, effective 18 April 2026 and based on 12 months of activity ending 30 September 2025, set minimums for retail, recurring telecommunications and cable, and supermarket merchants. The lowest published retail rung, Threshold III, requires a minimum of 19.2 million transactions and $1.08 billion in volume, with a maximum dispute financials ratio of 0.020% and PCI compliance. Supermarket Tier III requires 23.4 million transactions and $1.35 billion.

Qualification moves more than size does

The gap between fee programs inside the published schedule is larger than anything most merchants negotiate. In the consumer credit tables effective 18 April 2026, Non-Qualified Consumer Credit is listed at 3.15% + $0.10 across every card product column. The card-present and card-not-present programs above it are materially lower, and which one a sale lands in depends on the transaction data, the acceptance method and the merchant category — not on the size of the business submitting it. A growing merchant that adds a phone-order channel, or keys transactions that used to be dipped, or lets a terminal batch late, moves sales down that list while its volume goes up. Our downgrade guide covers how Visa qualification works and how to find the affected transactions on a statement.

Debit is capped by the issuer's size, not yours

Regulation II limits the interchange a covered issuer may receive on a debit transaction, and the Federal Reserve publishes the lists that decide who is covered. Institutions in the exempt category were determined to have, together with their affiliates, reported assets of less than $10 billion as of 31 December 2025; those at $10 billion or more are not exempt. The lists were revised on 27 May 2026. The practical consequence is worth stating plainly: the single largest structural difference in what you pay on a debit sale is decided by which bank issued the customer's card, which no amount of growth on your side affects. Visa's schedule reflects it with a separate regulated column. Our Regulation II guide covers the cap and the exemption in detail.

What is genuinely negotiable as you grow

Four things, and none of them are interchange. First, the pricing model: a bundled or tiered rate hides the split between the published input and your provider's margin, and moving to interchange-plus makes the margin visible and therefore comparable. Second, the markup itself — processor-set, not published, and the only number two quotes can actually be compared on once the model is the same. Third, fixed monthly charges: statement fees, monthly minimums, gateway fees and annual fees do not scale with you, so their weight in your effective rate falls automatically as volume rises, which is precisely why they are easy to leave in place unexamined. Fourth, terms rather than price: funding timing, reserve conditions, chargeback fee waivers and the notice period on a rate change. Our negotiation guide covers how to run that conversation, and our effective rate guide covers how to measure the result.

An illustrative example of what to measure

Illustrative example, made-up round numbers. A retailer processes $40,000 a month and pays $120 a month in fixed charges: a statement fee, a monthly minimum and a gateway fee. Those fixed charges are 0.30% of volume. At $120,000 a month, unchanged, the same $120 is 0.10%. The effective rate falls by 0.20 percentage points without a single term being renegotiated — which is exactly why a provider can show you a lower effective rate at higher volume while nothing has been given back. Measure the markup and the fixed charges separately from interchange, compare them against a statement rather than a quote, and treat any improvement that comes only from dividing the same fixed charges by a larger number as what it is. We publish no rate bands here because the honest ones do not exist.

About the rate tables on this page: Visa is the only card network that publishes a public US merchant interchange schedule, so the rate tables on this site are Visa-only. Mastercard, American Express and Discover do not publish an equivalent US merchant schedule, and their rates are neither shown above nor implied by these figures. Ask your processor for the rates that apply to each network on your account.
