MasterCard Excessive Chargeback Program
MasterCard designed the Excessive Chargeback Program (ECP) to encourage each Acquirer to closely monitor, on an ongoing basis, its chargeback performance at the Merchant level and to determine promptly when a MasterCard Merchant has exceeded or is likely to exceed the defined monthly chargeback thresholds.
AcquirerA licensed member who maintains Merchant relationships, receives all payment card transactions from the Merchant, and initiates that data into an interchange system.
Chargeback-to-Transaction Ratio (CTR)The CTR is the number of MasterCard chargebacks received by the Acquirer for a Merchant in a calendar month divided by the number of the Merchant’s MasterCard sales transactions in the preceding month acquired by that Acquirer.
Chargeback-Monitored Merchant (CMM)A CMM is a Merchant that has a CTR in excess of 100 basis points and at least 100 chargebacks in a calendar month. This is effectively an early warning classification for Merchants approaching ECM thresholds.
Excessive Chargeback Merchant (ECM)A Merchant is an ECM if in each of two consecutive calendar months (the “trigger months”), the Merchant has a minimum CTR of 150 basis points and at least 100 chargebacks in each month. This designation is maintained until the ECM’s CTR is below 150 basis points for two consecutive months.
Tier 1 ECMA Merchant is a Tier 1 ECM during the first through sixth month (whether consecutive or non-consecutive) that the Merchant is identified as an ECM.
Tier 2 ECMA Merchant is a Tier 2 ECM during the seventh through twelfth month (whether consecutive or non-consecutive) that the Merchant is identified as an ECM.
AssessmentsIn addition to any applicable assessments for ECM reports or late report submissions, MasterCard may assess the Acquirer for issuer reimbursement fees and violation assessments for excessive chargebacks arising from an ECM. MasterCard calculates the issuer reimbursement fees and assessments as described below and they apply in each calendar month that the ECM exceeds a CTR of 150 basis points after the first trigger month.
For the first 12 months of a Merchant’s identification as an ECM, MasterCard will consider the Merchant’s actual chargeback volume as a factor in its determination of Acquirer liability. During this period, MasterCard will assess the Acquirer the lesser of:
- The total of the issuer reimbursement plus violation assessment amounts, calculated as described below for a given month, or
- The Merchant’s chargeback dollar volume reported by the Acquirer for that month.
ECP Assessment CalculationMasterCard determines an Acquirer’s liability for the monthly issuer reimbursement fees and assessments for each ECM as set forth below. MasterCard calculates the issuer reimbursement fees in Steps 1, 2, and 3, and calculates the violation assessment in Step 4, as outlined below.
- Step 1. Calculate the CTR for each calendar month that the ECM exceeded a CTR of 150 basis points (which may also be expressed as 1.5% or 0.015).
- Step 2. From the total number of chargebacks in the above CTR calculation, subtract the number of chargebacks that account for the first 150 basis points of the CTR. (This amount is equivalent to 1.5 percent of the number of monthly sales transactions used to calculate the CTR.) The result is the number of chargebacks above the threshold of 150 basis points.
- Step 3. Multiply the result from Step 2 by $25 USD. This is the issuer reimbursement.
- Step 4. Adjust the result in Step 3 to reflect the extent that the Acquirer has exceeded the 150 basis points threshold by multiplying the value in Step 3 by the CTR (expressed as basis points). Divide this result by 100. This amount is the violation assessment.
Repeat Steps 1–4 for each calendar month (other than the first trigger month) that the ECM exceeded a CTR of 150 basis points or 1.5 percent.
ExampleIn the following example the Acquirer for Merchant ABC acquired MasterCard sales transactions and chargebacks over a six-month period as follows:
|Month||Billed||Chargebacks||CTR in Basis Point||Chargeback %|
February and March are the trigger months, as these are two consecutive months where the CTR exceeded 150 basis points. At the end of July, Merchant ABC was no longer an ECM as its CTR was below 150 basis points for two consecutive months. MasterCard calculates assessments and Issuer reimbursements for each of the months March through July.
For example, the assessment for April (using March sales transactions and April chargeback volumes) is calculated as follows:
- The CTR = April chargebacks/March sales transactions = 1,556/95,561 = 0.01628 or 163 basis points (rounded)
- The number of chargebacks in excess of the 150 basis points is determined by subtracting 1.5 percent of the March sales transactions from the number of April chargebacks. 1.5 percent of the March sales transactions (95,561 x 0.015) is 1,433. 1,556 – 1,433 = 123 chargebacks
- The issuer reimbursement for April is 123 x $25 = $3,075
- The violation assessment is ($3,075 x 163)/100 or 501,225/100 = $5,012.25
Using this methodology, the issuer reimbursement fees and assessments for the Acquirer for Merchant ABC are as follows:
|Febuary (first trigger month)||$0.00||$0.00||$0.00|
|March (second trigger month)||$5,075.00||$8,678.25||$13,753.25|
Example: For the month of March, the Acquirer reported Merchant ABC chargeback volume of 1,635 chargebacks totaling $12,145. This amount is less than the calculated amount of the issuer reimbursement plus violation assessment total of $13,753.25, as shown above for March. Therefore, MasterCard will assess the Acquirer the lesser chargeback volume amount rather than the greater calculated amount.
