The electromechanical brake force booster for a vehicle brake system comprises a drive arrangement for driving at least one actuating device which is designed for actuating a brake cylinder. The drive arrangement has at least one electric motor and a gearing for coupling the electric motor to the at least one actuating device. The gearing comprises at least one second spur gear and at least one first spur gear. Furthermore, the gearing has an intermediate gearing stage. The intermediate gearing stage couples the electric motor to the second spur gear and to the first spur gear in torque-transmitting fashion. The intermediate gearing stage drives the second spur gear directly and the first spur gear via at least one intermediate gear.
