When it comes to fraud, there’s a fine but clear line between “a little” and “too much.” The problem is that if your business starts to attract a disproportionate amount of fraudulent activity, Mastercard will take it personally. In this post, let’s talk about how Mastercard calculates its fraud threshold so that you can stay in compliance. ### Recommended reading - [Chargeback Legal Process: Is There a Step After Arbitration?](https://chargebacks911.com/chargeback-legal-process/) - [How to Identify & Prevent Shipping Scams in 2026](https://chargebacks911.com/shipping-scams/) - [Chargeback Stats: All the Key Dispute Data Points for 2026](https://chargebacks911.com/chargeback-stats/) - [PlayStation Chargebacks: Why Sony Suspends PSN Accounts](https://chargebacks911.com/playstation-chargebacks/) - [Web Authentication API: WebAuthn, Passkeys & Merchant Login](https://chargebacks911.com/web-authentication/) - [NEW DATA | FI Risk Resulting From Visa VAMP Requirements](https://chargebacks911.com/vamp-acquirer-data/) ## Which Transactions Count Toward Mastercard Fraud Limit? [Like I covered in this article](https://chargebacks911.com/mastercard-chargeback-threshold/), Mastercard has a firm limit for the volume of chargebacks you’re allowed to receive each month without incurring penalties. But, Mastercard also imposes a second limit that’s specific to chargebacks issued with a “fraud” code ([reason code 4837 — *No Cardholder Authorization*](https://chargebacks911.com/chargeback-reason-codes/mastercard/4837-no-cardholder-authorization/)). Allowable Mastercard fraud limits are based on the dollar value of all [chargebacks](https://chargebacks911.com/chargebacks/ "Chargebacks 101") you receive with a “fraud” reason code, plus the total number of fraudulent transactions as a portion of overall sales, represented in basis points. [Whether or not you deployed 3-D Secure](https://chargebacks911.com/fraud-prevention/3-d-secure/) is also a factor. ## What is the Mastercard Fraud Limit? In summary, there are four criteria that define the Mastercard fraud threshold. You must meet or exceed the limit for all four at the same time. If you do, you’ll be enrolled in the Mastercard EFM program: - 1. The number of fraudulent eCommerce transactions you process each month. - 2. The dollar value of the fraudulent eCommerce transactions you process during that month. - 3. The ratio of fraudulent transactions to legitimate ones, rendered in basis points. - 4. The rate at which you use 3D Secure to validate buyers (including data-only transactions). The limits for each criteria are outlined in the table below: #### Number of eCommerce Transactions 1,000 or More #### Fraud Chargeback Amount €/$50,000 or More #### Fraud Chargeback Basis Points 50 or More #### 3DS Utilization Rate Used on <10% Transactions in Non-Regulated Countries #### 3DS Utilization Rate Used on <50% Transactions in Regulated Countries Important!You can substantially minimize your chances of breaching the Mastercard fraud threshold by deploying 3D Secure whenever possible.

Mastercard fraud thresholds are set limits within the card network’s rulesets to identify and respond to merchants with high levels of fraudulent transactions. The program is designed to protect the integrity of the Mastercard payment system by reducing fraud and ensuring that merchants take appropriate action to lower their fraud rates. Ultimately, the Mastercard fraud threshold is meant to balance consumer protection with a fair operational landscape for merchants. Adhering to these standards is about compliance and committing to the best practices that define a trusted and customer-centric eCommerce experience. If you exceed the Mastercard fraud threshold, you can face a variety of consequences. You could see financial penalties, increased scrutiny, and potential loss of processing capabilities if the situation is not fixed quickly. ## Fee Schedule for Violating the Mastercard Fraud Threshold The Mastercard EFM initiative is designed to refine enforcement procedures and enhance the speed of dialogue between acquirers and the card network. This program aims to sharpen the precision of merchant compliance and bolster responsibility in the process. Like with the Excessive Chargeback Merchant program, the fines associated with the program get higher the longer you continue to exceed the Mastercard chargeback limits: Number of Months Above EFM ThresholdsViolation Assessment102EUR/USD 5003EUR/USD 1,0004 to 6EUR/USD 5,0007 to 11EUR/USD 25,00012 to 18EUR/USD 50,00019 +EUR/USD 100,000Also like the ECM, you will incur financial penalties should you exceed these limits. These will escalate with every month you remain within the program. ## Other Penalties for Non-Compliance When your fraud ratio is close to, or in excess of Mastercard’s established limit, your financial institution will likely adopt some protective actions to protect their position. One common response involves freezing your merchant account. At minimum, this step temporarily blocks access to the working capital that your business depends on for daily operations. Remember that reducing your fraud rate below Mastercard's benchmarks doesn't automatically remove you from monitoring programs, either. You have to maintain compliant levels for *three straight months* before Mastercard will recognize your “good standing” status. Mastercard has rigorous documentation requirements, compelling banks to provide detailed monthly assessments of every merchant's performance, with fees between $50-$300 per submission. Missing these deadlines carries significant consequences; penalties can reach $1,000 per day for each overdue report.

You'll likely shoulder the financial responsibility for these additional oversight measures. Following twelve months of program participation, acquiring banks face substantial compliance violations potentially reaching $50,000 per month. Given these steep costs and associated risks, most processors will simply end the merchant relationship. When this happens, the bank has to put you on the [MATCH List](https://chargebacks911.com/high-risk/high-risk-merchants/match-list/ "MATCH List"); a database containing merchants whose accounts were closed due to excessive disputes or fraud concerns. MATCH placement creates substantial barriers to obtaining future merchant processing services through traditional channels. ## Protect Your Business Against Mastercard Chargebacks So what can you do to protect your business long-term? First, recognize that many disputes — even if they’re filed with a “fraud” reason code — can still be invalid. As many as three out of four chargebacks are probably cases of first-party (or “friendly”) fraud. This means they were filed without a valid reason. You have the right to challenge these invalid chargebacks through [the representment process](https://chargebacks911.com/representment/). If you fight a customer dispute and win, you can recapture a portion of the amount disputed. Winning a dispute won’t undo the damage to your Mastercard fraud rate. Chargeback rates are calculated using the total number of chargebacks issued, regardless of whether they get reversed later, so once the damage is done... it’s unavoidable. The same applies to your fraud-to-transaction ratio as well. That’s why it’s crucial that you do everything possible to prevent fraud before it happens. Staying below the Mastercard fraud threshold means implementing a comprehensive strategy that addresses fraud-related disputes directly at their sources.
