Drempels voor terugboekingen in 2026: Visa VAMP- en Mastercard ECM-limieten

A chargeback threshold is the maximum chargeback-to-transaction ratio a card network permits before it flags your account, enrolls you in a monitoring program, and starts applying fines. In 2026 the two limits that matter most are Visa's VAMP ratio of 1.5% and Mastercard's ECM trigger of a 1.5% ratio combined with 100+ chargebacks in a month. Stay under both and you avoid penalties.

The numbers moved in 2026. Visa's Acquirer Monitoring Program (VAMP) reached its final, stricter enforcement stage on April 1, 2026, and Mastercard's excessive-chargeback tiers remain in force. If you sell online, understanding these thresholds is the difference between a healthy merchant account and one facing fees, reserves, or termination.

What Is a Chargeback Threshold?

A chargeback threshold is a predetermined limit, set by card networks such as Visa and Mastercard, that defines the maximum allowable chargeback ratio for a merchant. The ratio is calculated by dividing your chargebacks (and, under Visa's newer methodology, fraud reports) by your total processed transactions, expressed as a percentage.

Zodra u een drempel overschrijdt, wordt u door het netwerk ingeschreven in een toezichtsprogramma. Dat houdt in: kosten per geschil, maandelijkse boetes, verplichte herstelplannen en hogere doorlopende reserves die door uw acquirer worden aangehouden. Aanhoudende overtredingen kunnen leiden tot beëindiging van uw account en plaatsing op de MATCH-lijst, waardoor het tot wel vijf jaar lang uiterst moeilijk wordt om een nieuwe merchant-account te openen.

Thresholds exist because chargebacks signal risk to issuers, acquirers, and the networks themselves. A rising ratio usually points to fraud, poor fulfillment, unclear billing, or weak dispute handling, so tightening fraud screening is often the fastest way to bring VAMP and ECM numbers back down. If you are already over a line, our 30/60/90-day plan to reduce chargebacks orders the fixes by speed of impact. Keeping your ratio low is not just about avoiding fines. It protects your processing relationships and your reputation. For a broader primer, see our guide on how to avoid chargebacks.

What is the Visa VAMP threshold in 2026?

Het Visa Acquirer Monitoring Program (VAMP) verving de oudere VDMP- en VFMP-programma’s van Visa en ging op 1 april 2025 van start met een gefaseerde invoering. Tijdens de beginperiode bedroeg de VAMP-ratio op handelaarsniveau 2,2%. Op 1 april 2026 daalde dat plafond voor de meeste regio’s naar 1,5% (Centraal- en Oost-Europa, het Midden-Oosten en Afrika behouden voorlopig 2,2%).

What makes VAMP different is its methodology. The VAMP ratio combines fraud reports (TC40) and disputes (TC15) in the numerator, divided by settled transactions (TC05). Older programs counted only chargebacks, so many merchants who felt safe before now find themselves closer to the line. An account is only considered for VAMP enrollment once it reaches a minimum of roughly 1,500 combined dispute and fraud transactions per month, so this count applies alongside the ratio thresholds. A fraud alert that is not refunded quickly enough can count separately from the resulting chargeback.

Visa hanteert tevens een enumeratieverhouding om het testen van kaarten tegen te gaan. Handelaars moeten onder een enumeratieverhouding van 20% blijven (bevestigde geënumereerde transacties gedeeld door afgewikkelde transacties). Wanneer u de VAMP-drempel overschrijdt, brengen acquirers doorgaans kosten in rekening van ongeveer $8 per geschil voor elke maand dat u boven de drempel zit.

What is Mastercard ECM in 2026?

Mastercard's Excessive Chargeback Merchant (ECM) program is the equivalent limit on the Mastercard network. A merchant is designated ECM when they hit both a chargeback ratio of 1.5% or higher AND 100 or more chargebacks in a single calendar month, sustained for two consecutive months before Mastercard formally applies the designation. Visa runs a similar buffer: a first-time VAMP breach within a rolling 12-month period qualifies for a three-month grace period before enrollment.

Mastercard also runs a higher tier, the High Excessive Chargeback Merchant (HECM), which triggers at a 3% ratio AND 300+ chargebacks. Fines start around $1,000 in the early months and escalate each month you remain in the program, climbing into the tens or hundreds of thousands of dollars for prolonged HECM status, plus an Issuer Recovery Assessment on chargebacks above 300. Exiting requires three consecutive months below the threshold. For the full ratio comparison across Visa, Mastercard, Amex, and Discover, plus the platform-level limits set by PayPal, Stripe, and Shopify, see our complete chargeback threshold guide. Mastercard also runs a separate merchant audit initiative, the Mastercard GMAP, which is not ratio-based like ECM.

In de onderstaande tabel staan de huidige drempels waarbinnen handelaren moeten blijven, samen met de gevolgen van het overschrijden van elke drempel.

VAMP versus ECM: hoe verhouden deze twee programma’s zich tot elkaar?

Handelaren gaan er vaak vanuit dat Visa en Mastercard risico’s op dezelfde manier inschatten. Dat is echter niet het geval. In de onderstaande vergelijking worden de belangrijkste verschillen belicht, zodat u elk netwerk op de juiste manier kunt volgen.

How is a chargeback ratio calculated?

The classic formula is simple: divide the number of chargebacks in a month by the number of transactions, then multiply by 100. If you processed 10,000 transactions and received 90 chargebacks, your ratio is 0.9%.

De VAMP-methodologie van Visa neemt fraudemeldingen mee in de teller, waardoor dezelfde handelaar een aanzienlijk hogere VAMP-ratio zou kunnen laten zien dan zijn ruwe chargeback-ratio. Sommige verwerkers berekenen de ratio op basis van het aantal transacties van de huidige maand, anderen gebruiken de vorige maand, wat de ratio’s tijdens een periode van snelle groei kan vertekenen. Controleer altijd welke methode uw acquirer hanteert en houd de indicator wekelijks in de gaten in plaats van te wachten tot het einde van de maand.

Do AI Agent Purchases Count Toward These Thresholds?

Yes. Whether a dispute stems from a human checkout or an autonomous shopping agent completing a purchase on a cardholder's behalf, it still counts against the same VAMP and ECM ratios described above; the networks measure the transaction outcome, not who initiated it. As agentic commerce grows, merchants accepting agent-initiated orders should treat those disputes as fully exposed to every threshold on this page. See AI agent chargeback liability for where responsibility currently sits when an agent completes an unauthorized purchase.

What chargeback ratio is considered safe?

Across the industry, an acceptable chargeback rate is generally anything under 0.9%. To build a buffer, aim for 0.65% or below, which keeps you clear of Visa's early-warning territory and comfortably under both VAMP and ECM. Most acquirers begin scrutinizing accounts that approach 1%, and many will terminate merchants that sustain a rate above that level.

High-risk verticals such as subscriptions, travel, and digital goods face tighter internal limits from their processors even when network thresholds are the same. If you operate in one of these categories, treat 0.5% as your working target. Your payment service provider can also set its own internal cap below any network minimum, so confirm that limit directly rather than assuming VAMP or ECM is the first line you'll hit.
