Mastercard excessive chargeback program
What is Mastercard excessive chargeback program?
Mastercard Excessive Chargeback Program (ECP) is a compliance program run by Mastercard that identifies and monitors merchants whose volumes rise above the network's acceptable limits. Merchants flagged under the program face heightened monitoring and escalating penalties until they bring their chargeback rates back within range.
The program protects the from the financial and reputational risk that excessive chargebacks create. Mastercard tracks each merchant's activity through its , and once a merchant crosses a defined tier, the acquirer is notified and the merchant enters a remediation timeline with fixed deadlines.
The trigger is a pattern, not a single dispute. A merchant lands in the program when its chargeback rate stays above the network's limit across a monitoring month, which is why the program targets structural problems, such as unclear billing descriptors or weak fraud screening, rather than isolated incidents.
Key facts
- Also known as: Excessive Chargeback Program (ECP)
- Run by: Mastercard, enforced through the merchant's acquirer
- Measured by: the merchant's monthly - chargebacks as a share of transactions
- Tiers: two escalating levels, the Excessive Chargeback Merchant (ECM) tier and the more severe High Excessive Chargeback Merchant (HECM) tier
- Applies to: any merchant processing Mastercard-branded transactions
How the program works
- Monitoring. Mastercard tracks each merchant's chargeback-to-transaction ratio month over month, reported through the acquirer.
- Classification. When a merchant exceeds the program's limit, it's placed into a tier - the standard ECM level, or the HECM level for higher, sustained volumes.
- Notification. The acquirer is notified and passes the program's requirements and deadlines to the merchant.
- Remediation. The merchant works to reduce chargebacks within the set timeframe, often by tightening fraud controls and addressing the driving the volume.
- Escalation. Continued breaches move the merchant to the higher tier, increase the fines, and can end in loss of Mastercard processing.
Who it applies to
The program applies to any merchant that accepts Mastercard payments, but the risk concentrates in card-not-present, subscription, and high-risk verticals, where dispute rates and run higher. Recurring billing adds exposure because a single unrecognized rebill can generate a chargeback every cycle until the underlying issue is fixed.
Mastercard runs a parallel track, the , that monitors fraud rather than chargeback volume, so a merchant can be assessed against either or both at the same time.
Penalties for non-compliance
Penalties escalate the longer a merchant stays in the program:
- Monthly assessments that increase at each tier and for each month spent above the limit
- Issuer recovery, where the is reimbursed for qualifying chargeback amounts
- Higher processing costs and reserves imposed by the acquirer to cover exposure
- Account termination and placement on the industry's terminated-merchant file if the rate isn't corrected
Bringing the chargeback rate below the threshold and holding it there for the required period exits the merchant from the program.
