A torque compensation apparatus for an electric power steering system may include: a temperature sensor configured to sense the initial temperature around the electric power steering system when a vehicle is started; a motor position sensor configured to sense a motor angle of the electric power steering system; a timer configured to detect an operation time of the started vehicle; and a controller configured to calculate a compensation gain when the initial temperature corresponds to a preset low-temperature state, the compensation gain reflects the increasing ambient temperature, and is based on the motor angles accumulated during steering and the accumulative operation time detected through the timer after the start of the vehicle; and the controller outputs the compensation gain to compensate for a motor output torque of the electric power steering system.
