The present invention relates to an assist torque compensation apparatus for a vehicle and a method for the same. The assist torque compensation apparatus for a vehicle comprises: an assist torque calculation unit calculating assist torque corresponding to a vehicle speed according to an analysis result after analyzing steering characteristics of a vehicle on steering by using a yaw rate, a steering angular speed and the vehicle speed; a rapid steering assist torque calculation unit calculating rapid steering assist torque by reflecting column torque and a lateral accelerator on the assist torque calculated by the assist torque calculation unit; and a final assist torque calculation unit calculating final assist torque by reflecting the rapid steering assist torque on basic assist torque calculated by an MDPS system. The present invention outputs assist torque suitable for the steering characteristics by classifying the steering characteristics according to the vehicle speed.
