Disclosed are a system for calculating amount of regenerative braking of a hybrid vehicle and a method thereof. The system for calculating the amount of regenerative braking of a hybrid vehicle according to an embodiment of the present invention includes: a driving information detector for collecting driving information for regenerative braking determination of the hybrid vehicle; a motor controller which controls driving and torque of a motor in accordance with an applied control signal, and stores electricity generated by the motor during regenerative braking in a battery; a dual clutch transmission (DCT) controlling gear ratio using two clutches; a transmission controller detecting hand over ratio in consideration of torque ratio between a gear step before shifting and a gear step after shifting in a torque phase of the dual clutch transmission if gear shifting is performed during regeneration; and a hybrid controller calculating the amount of regenerative braking on the basis of the motor torque and the gear ratio calculated using the hand over ratio of the torque phase section. The system of the present invention can improve fuel efficiency and driving performance of a vehicle.
