A vehicle running resistance calculation method includes: a step in which a controller receives a rotation speed of a driving source of a vehicle and an inclination angle of a road on which the vehicle is running, which is detected by an inclination angle sensor; a step in which the controller calculates the torque of the driving source based on the rotation speed of the driving source and calculates an inclination angle of the road based on the torque of the driving source; a step in which the controller determines whether the inclination angle of the road based on the torque of the driving source exceeds the inclination angle of the road detected by the inclination angle sensor; and a step in which when the inclination angle of the road based on the torque of the driving source is less than or equal to the inclination angle of the road detected by the inclination sensor, the controller determines that there is no object towed by the vehicle, and calculates the running resistance of the vehicle based on the inclination angle of the road according to the torque of the driving source. Therefore, the present invention is capable of accurately and quickly calculating the running resistance of the vehicle in real time.
