What a chargeback threshold is
A chargeback threshold is the point at which a card-network monitoring program flags your business based on dispute or fraud activity. Visa and Mastercard set different program rules, so there is no single percentage that applies to every merchant. Some thresholds require both a minimum event count and a minimum rate.
The threshold is the trigger, while your chargeback ratio is a rate used to measure activity against transactions. A chargeback filed in a month can count toward a program threshold even if you later challenge it successfully. Your ratio and the applicable program threshold are related, but they are not the same measure.
A threshold is a program trigger, not a universal 1% limit. Track the count and the rate that apply to your business.
The Visa and Mastercard trigger lines
As of April 1, 2026, Visa's US VAMP excessive threshold is a 1.5% ratio and at least 1,500 combined fraud reports and disputes in a month. The VAMP ratio adds TC40 fraud reports to TC15 disputes, then divides by settled card-not-present transactions. The threshold was 2.2% from June 2025 through March 2026.
As of 2026, Mastercard's Excessive Chargeback Program has two levels. ECM requires at least 100 chargebacks and a 1.5% chargeback-to-transaction ratio in a month. HECM requires at least 300 chargebacks and a 3.0% ratio. Both the count and the ratio must meet the applicable level. These figures are program triggers, not a universal safe harbor for every acquirer.
What crossing a threshold can mean
Crossing a program threshold puts your account under formal monitoring and can lead to penalties. Continued high dispute activity can put your ability to accept cards at risk. The exact consequences and charges depend on the program and your acquiring relationship, so do not assume a single fee or penalty schedule applies to every business.
There is no standard statement line called "chargeback threshold." Look for monitoring notices, dispute counts, fraud-report counts, and any program or penalty charges listed by your acquirer. Compare the notice's month and counting method with your own settled transaction and dispute records before treating a percentage as the full picture.
What you can actually change
You cannot change the network's program thresholds, but you can reduce the disputes and fraud reports counted toward them. Track the applicable monthly count and ratio together, since meeting both conditions triggers the Visa or Mastercard levels described above.
- Review dispute and fraud counts by month, then compare them with settled card-not-present transactions and your acquirer's program notice.
- Use clear billing descriptors and make cancellation and refund steps easy to find, reducing disputes from customers who do not recognize a charge.
- Resolve eligible inquiries before they become formal chargebacks, and use fraud controls or 3-D Secure where appropriate to limit fraud-related disputes.
- Keep evidence and response deadlines organized so you can challenge disputes with records that support the transaction.
- Identify your program. Match any monitoring notice to the Visa VAMP or Mastercard ECP rules and counting period it names.
- Track both measures. Record monthly disputes, fraud reports, and settled transactions so you can calculate the relevant rate and event count.
- Fix dispute causes. Review recurring customer complaints, unclear descriptors, and fraud patterns before they generate more formal disputes.
Frequently asked questions
Is a chargeback threshold the same as a chargeback ratio?
No. Your chargeback ratio is a rate that measures disputes against transactions. A threshold is the program trigger that uses a rate, a minimum count, or both to place an account under monitoring. Visa VAMP and Mastercard ECP use distinct rules.
What is the Visa chargeback threshold in the US?
As of April 1, 2026, Visa's US VAMP excessive threshold is a 1.5% ratio with at least 1,500 combined fraud reports and disputes in a month. VAMP divides TC40 fraud reports plus TC15 disputes by settled card-not-present transactions.
What happens if your business crosses a chargeback threshold?
Your account can enter a card-network monitoring program, which can bring penalties and increased risk to your ability to process payments. The applicable program determines the consequences. Check the notice for its counting period, required action, and any stated charges.
