Abstract: A system for calculating postal charges receives detailed information and configuration information about a bulk mail, and collects charge-calculation information on the basis of the detailed information and the configuration information. Then, the system determines discount rates for the bulk mail on the basis of the charge-calculation information, and generates charge information for the mails in consideration of the discount rates. Accordingly, the system for calculating postal charges can provide optimum charges for the mails to a client before the reception of the mails.
