Mastercard Chargeback Thresholds and Keep Up with Them
Chargebacks can significantly impact a business, especially when they surpass Mastercard’s established thresholds. Not only do excessive chargebacks result in hefty fines, but they can also jeopardize your ability to process payments. Staying on top of Mastercard’s chargeback limits and implementing proactive measures is essential to avoid these risks. In this post, we’ll dive into Mastercard’s chargeback thresholds, the potential penalties for noncompliance, and effective strategies to keep your chargeback rate in check and protect your business from costly disruptions.
Fraud & Chargeback Ratios Explained
Fraud and chargeback ratios are key metrics used by financial institutions, payment processors, and merchants to assess the prevalence of fraudulent transactions and customer chargebacks within a given period. These ratios help in identifying potential risks, maintaining compliance with regulatory standards, and ensuring the integrity of payment systems.
Fraud Ratio
The fraud ratio measures the proportion of total transactions that are identified as fraudulent. It is usually calculated using the following formula:
Fraud Ratio=(Total Fraudulent Transactions/Total Transactions Processed)×100
A high fraud ratio indicates a significant occurrence of unauthorized or deceitful transactions, which may result from identity theft, card-not-present fraud, or other illicit activities. Payment networks and regulatory bodies, such as Mastercard, often set threshold limits for acceptable fraud ratios, and exceeding these limits can lead to penalties or additional security measures for merchants.
Chargeback Ratio
The chargeback ratio, also referred to as the chargeback ratio, represents the percentage of transactions that customers contest due to unauthorized charges, service dissatisfaction, or unfulfilled orders. It is calculated as follows:
Chargeback Ratio=(Total Disputed Transactions/Total Transactions Processed)×100
A high chargeback ratio may indicate issues such as poor customer service, misleading product descriptions, or fraudulent chargebacks (also known as friendly fraud). Businesses that maintain a low chargeback ratio enhance customer trust and reduce financial liabilities associated with chargeback fees and lost revenue.
Mastercard Chargeback Thresholds
Mastercard chargeback thresholds are predefined limits set by Mastercard to regulate the number of chargebacks a merchant can incur before facing penalties or additional oversight. These thresholds serve as a risk management measure to ensure that merchants maintain responsible business practices and minimize transaction chargebacks.
Thus, Mastercard operates two key monitoring programs for merchants that exceed acceptable chargeback levels:
- Excessive Chargeback Merchant (ECM) Program. Merchants are flagged when they exceed 100 chargebacks in a month and have a chargeback ratio of 1.5% or higher.
- High Excessive Chargeback Merchant (HECM) Program. Merchants enter this category if they exceed 300 chargebacks per month and have a chargeback ratio of 3% or higher.
Each program has distinct thresholds based on the chargeback-to-transaction ratio and the absolute number of chargebacks received within a given month. Not complying with these thresholds leads to penalties and fines.
Mastercard Fraud Thresholds
Mastercard fraud thresholds are predefined limits established by Mastercard to monitor and control fraudulent transaction activity among merchants and financial institutions. These thresholds help maintain the security of the payment ecosystem by ensuring that businesses take appropriate measures to prevent fraud and unauthorized transactions.
Therefore, Mastercard oversees fraud levels through structured monitoring programs designed to identify and mitigate excessive fraudulent activity. The primary programs include:
- Excessive Fraud Merchant (EFM) Program. Merchants are identified if they exceed $50,000 in fraudulent transactions and maintain a fraud ratio of 0.50% or higher within a given month.
- High-Risk Excessive Fraud Merchant (HREFM) Program. Merchants fall into this category if they exceed $500,000 in fraudulent transactions and have a fraud ratio of 1% or higher.
Compliance with these thresholds is of crucial importance for merchants since violating them inevitably leads to penalties and fees.

Consequences of Noncompliance with Mastercard Thresholds
Failure to comply with Mastercard’s chargeback and fraud thresholds results in severe penalties, including fines, operational restrictions, and potential termination of payment processing privileges. Therefore, the key consequences include the following:
- Enrollment in monitoring programs. Merchants exceeding thresholds are placed in Mastercard’s monitoring programs (ECM, HECM, EFM, HREFM) and must take corrective action.
- Financial penalties. Noncompliance leads to escalating fines, higher processing fees, and remediation costs.
- Mandatory corrective measures. Merchants must adopt fraud prevention tools, improve customer service, and submit compliance reports to acquirers.
- Increased bank scrutiny. Acquiring banks may impose stricter underwriting, higher reserve requirements, or limit transaction processing.
- Merchant account termination. Continued noncompliance may lead to account closure, inability to process Mastercard payments, and placement on the MATCH list, making it difficult to secure future payment processing.
To avoid these risks, merchants must proactively monitor chargeback and fraud ratios, implement security measures, and adhere to industry best practices. One of the best ways to stay within chargeback and fraud thresholds is by means of using chargeback prevention alerts and fraud protection services like the one available within MidArmor.
Penalties & Fines
Mastercard imposes strict penalties on merchants who exceed chargeback thresholds, ensuring compliance with industry standards and minimizing financial risks. These penalties escalate based on the duration and severity of noncompliance, with fees increasing the longer a merchant remains in a monitoring program. The table below outlines the key fines and penalties associated with Mastercard chargeback violations.
Months Above Thresholds | ECM Program | HECM Program | |
---|---|---|---|
Violation Assessment | Violation Assessment | Issuer Recovery Assessment | |
1 month | 0 | 0 | - |
2 months | EUR/USD 1,000 | EUR/USD 1,000 | - |
3 months | EUR/USD 1,000 | EUR/USD 2,000 | - |
4-6 months | EUR/USD 5,000 | EUR/USD 10,000 | + |
7-11 months | EUR/USD 25,000 | EUR/USD 50,000 | + |
12-18 months | EUR/USD 50,000 | EUR/USD 100,000 | + |
Over 19 months | EUR/USD 100,000 | EUR/USD 200,000 | + |
At the same time, to maintain a secure payment ecosystem, Mastercard enforces strict fraud thresholds, penalizing merchants who exceed acceptable fraud levels. These penalties escalate based on the severity and duration of noncompliance, with fines increasing the longer a merchant remains in a fraud monitoring program. The table below provides an overview of Mastercard’s fraud threshold penalties and associated fines.
Months Above EFM Thresholds | Violation Assessment |
---|---|
1 month | 0 |
2 months | EUR/USD 500 |
3 months | EUR/USD 1,000 |
4-6 months | EUR/USD 5,000 |
7-11 months | EUR/USD 25,000 |
12-18 months | EUR/USD 50,000 |
Over 19 months | EUR/USD 100,000 |
As you can see, the penalties for noncompliance with Mastercard fraud and chargeback thresholds are pretty severe, which is why it is in the best interests of merchants to prevent excessive chargebacks and fraud by means of special software.
How to Comply with Mastercard Thresholds
To avoid penalties and maintain secure transactions, merchants must proactively manage chargebacks and fraud. Thus, key compliance strategies include:
- Monitor chargeback & fraud ratios. Regularly track transaction reports, set alerts for rising rates, and collaborate with acquiring banks.
- Enhance fraud prevention. Use 3D Secure, AI fraud detection, AVS, CVV, tokenization, and encryption to prevent unauthorized transactions.
- Improve customer service. Provide clear product details, transparent policies, and responsive support to prevent chargebacks.
- Manage chargebacks effectively. Respond promptly with strong evidence, use chargeback alerts, and leverage chargeback management services.
- Stay updated on Mastercard guidelines. Review policy changes, participate in fraud prevention programs, and implement best practices.
By following these measures, merchants can minimize chargebacks and fraud, ensuring compliance and financial stability.
