PURPOSE: A calculating method and a display device of a fuel consumption amount and an average driving fuel efficiency of a vehicle are provided to effectively calculate the fuel consumption amount and the fuel efficiency and display the fuel consumption amount and the fuel efficiency at a real time. CONSTITUTION: A display device of a fuel efficiency comprises a fuel efficiency display unit and a reset unit. The display unit displays a moment driving fuel efficiency, an accumulated average fuel efficiency, an accumulated fuel consumed amount, a running distance and so on. The display unit comprises an LED(Light Emitting Device) display unit(1) and an FND display unit(2). The LED display unit leads that a driver drives with good fuel efficiency by displaying the immediate driving fuel efficiency at a real time. The FND display unit selects one of the accumulated fuel efficiency, the accumulated fuel consumed amount, a fuel consumed amount per hour and a running distance by using a switch. A reset and a selection switch unit(3) selects the information and reset every information when the switch is pressed over 3 seconds. Thereby, the consumption of the fuel is reduced and the safe driving is performed.
