At-a-Glance
Visa tightened its Visa Acquirer Monitoring Program (VAMP) “Excessive” merchant threshold from 2.2% to 1.5%, effective April 1, 2026. The ratio counts fraud reports plus disputes against total settled card-not-present transactions — which means the holiday season, when both sales volume and fraud attempts spike together, is exactly when a retailer is most likely to cross it. With clear monitoring, the right authentication tools, and a plan before Black Friday, most merchants can stay comfortably under the new line.
Why This Matters Now
If you sell online, you’ve probably heard chargebacks are a cost of doing business. What’s changed is how closely the card networks are watching. Visa’s VAMP threshold — the ratio that determines whether a merchant gets flagged as “excessive” — dropped from 2.2% to 1.5% this year. That’s a meaningful tightening, and it lands right before the quarter when card-not-present volume, and fraud attempts, both climb fastest.
Industry chargeback data backs up why this timing matters: U.S. chargeback volume is projected to reach roughly 146 million transactions in 2026, and card-not-present fraud losses are estimated to climb toward $28 billion for the year. None of that is evenly distributed across the calendar — it concentrates hard in November and December.
What the VAMP Ratio Actually Counts
The VAMP ratio isn’t just chargebacks. It combines:
- Fraud reports — transactions flagged as fraudulent by the cardholder’s bank
- Disputes — chargebacks filed for any reason, including “friendly fraud” where a legitimate customer disputes a real purchase
Both get counted against your total settled card-not-present transaction volume for the period. That means a spike in either fraud attempts or return-driven disputes during the holidays can push your ratio up fast — even if your actual fraud losses feel manageable in dollar terms.
Why Holiday Season Is the Riskiest Window
Two things happen at once during Q4:
- Transaction volume surges. More card-not-present sales means more opportunities for both fraud and disputes.
- Friendly fraud rises. Gift purchases, “I didn’t recognize this charge” confusion, and buyer’s remorse after big-ticket holiday spending all tend to push dispute rates up — separate from actual criminal fraud.
Practical Steps Before Black Friday
- Know your current ratio. Ask your processor for your VAMP-relevant fraud and dispute rate now, not in November.
- Tighten authentication on card-not-present sales. Address verification (AVS) and CVV checks catch a meaningful share of fraud attempts before they become chargebacks.
- Use dispute alerts. Many processors offer early-warning systems that flag a dispute before it escalates to a full chargeback — giving you a chance to refund or resolve it first.
- Communicate clearly at checkout and on statements. A large share of “friendly fraud” disputes happen simply because a customer didn’t recognize the charge description on their statement. Clear, recognizable billing descriptors reduce this category significantly.
- Watch your refund process. Making refunds easy and fast reduces the temptation for customers to skip straight to a dispute.
The Bottom Line
The 1.5% threshold isn’t a reason to panic, but it is a reason to check your numbers before your busiest quarter, not after. A little preparation in September saves a difficult conversation with your processor in January.

FAQ
What happens if I go over the VAMP threshold?
Processors and card networks can apply monitoring fees, require a remediation plan, or in persistent cases restrict processing. It’s best addressed before it happens.
Does this apply to in-person retail sales?
The VAMP ratio is specific to card-not-present transactions — online, phone, and keyed-in sales. In-person EMV and tap transactions carry a different, much lower average fraud rate.
Can Media Payments Group help me check my current ratio?
Yes — our team can review your processing statements and flag where your fraud and dispute rate currently stands relative to the new threshold.
