A mobile telephone with an accounting function enables a user to visually check a call charge through a display unit. The mobile telephone includes a display unit for displaying a call charge according to call charge data, and a controller for calculating the call charge at a predetermined time interval beginning at a time when a call success message is received from a mobile telephone switching office, and providing the call charge data to the display. The mobile telephone includes a memory for storing the call charge, and a keypad with which a user can input charge rate data, wherein the controller stores the charge rate in the memory and calculates the call charge based on the charge rate.
