A chargeback ratio is a critical performance metric used by acquiring banks and payment processors to evaluate the ongoing risk level of a merchant. It represents the percentage of a merchant's total transactions that result in a chargeback—a forced reversal of funds initiated by the cardholder's issuing bank due to fraud, disputes, or non-delivery of goods.
Why Do Acquirers Monitor It?
Card networks (like Visa and Mastercard) enforce strict limits on acceptable chargeback ratios, typically around 0.9% to 1% of total transactions. If a merchant exceeds this threshold, they are placed in advanced monitoring programs and subjected to massive fines. For the acquiring bank, a merchant with a high chargeback ratio represents a direct financial liability, as the acquirer is ultimately responsible for the refunded money if the merchant goes bankrupt.
How to Calculate the Ratio
While different card networks have slight variations, the standard formula is dividing the total number of chargebacks in a given month by the total number of transactions processed in that same month.
