Abstract: Few merchants are in a position to understand how changes to processes or procedures may alter the issuer risk and/or subsequent transaction processing costs. Merchants would prefer to be provided with estimated Interchange fees associated with a financial transaction in real-time. To provide a merchant with an estimated Interchange fee in real-time, a financial transaction request may be received from the merchant and used to determine the estimated Interchange fee. The estimated Interchange fee may then be transmitted to a merchant in real-time. The estimated Interchange fee may be representative of an actual Interchange fee associated with a financial transaction. Estimated Interchange fees may be provided as part of an authorization or settlement processing method.
