An excessive chargeback program is the card networks putting your merchant account on a clock. You are measured monthly, fined per dispute, and given a number of months to get the ratio back under the threshold. Merchants who do not get out lose the ability to accept cards.
This is the mechanism that makes chargebacks an existential problem rather than a cost of doing business, and it is the part almost every vendor selling you a chargeback product leaves out of the pitch.
Visa and Mastercard each run a monitoring program that watches the ratio of disputes to transactions at every merchant account. Cross a threshold and your acquirer is notified, you are enrolled, and a schedule of fines and remediation deadlines starts running.
Two things about this surprise most merchants. The first is that enrollment is automatic: nobody reviews your business or your intentions, the ratio crosses a line and the program starts. The second is that it is your acquirer who carries the penalty and passes it to you, which is why the pressure to fix it arrives as an ultimatum rather than a conversation.
Visa flags a merchant as excessive at a 1.5 percent ratio, reduced from 2.2 percent, effective April 2026. Merchants in the excessive bracket are charged 8 dollars per dispute and face restrictions and possible termination.
The reduction matters more than the fine. A merchant sitting comfortably under the old 2.2 percent line can be in breach at 1.5 percent without their dispute count changing at all. If nobody has recalculated your ratio against the current threshold, that is the first thing to do.
Mastercard’s Excessive Chargeback Program flags merchants at a 1 percent ratio across two consecutive months with 100 or more chargebacks, and targets 0.7 percent. The two-consecutive-months structure means a single bad month is a warning rather than an enrollment, which is the one piece of breathing room in any of this.
Both networks publish their own current program rules, and both have revised thresholds downward in recent years. Treat any threshold you were told more than a year ago as out of date.
Enrollment brings three things, in this order: per-dispute fees on top of your normal chargeback fee, a remediation deadline, and a review. Depending on how long you stay above the threshold, the consequences escalate from fees to restrictions on how you can process, and ultimately to termination of the merchant account.
Termination is not the end of it either. An account closed for excessive chargebacks can follow the business into its next application, which is why merchants who ignore the early months often find the problem has become a boarding problem rather than a pricing one.
You exit by getting the monthly ratio back under the threshold and keeping it there. Because measurement is monthly, nothing you do this week shows up until next month’s numbers close, and the programs generally require consecutive clean months rather than a single good one.
That timing is the whole argument for acting early. The tools that work fastest are the ones that stop a dispute being filed: fixing the billing descriptor, making yourself easy to contact, and using issuer alerts to refund inside the window before a chargeback is recorded. The full sequence is here.
Every dispute carries a chargeback fee from your processor, and that fee is a marked-up line like any other. Merchants in a monitoring program are paying it more often than anyone, which makes it worth knowing exactly what you are charged per dispute and what the underlying cost is.
