The invention discloses a rapid calculation method for an elevator balance coefficient. The rapid calculation method comprises the following steps of: A, using a clip-on ammeter to test current values when an elevator ascends and descends in a no-load mode till a lift car and a counterweight are located at the same horizontal position; B, inquiring a nameplate of an elevator traction machine to confirm rated current and rated torque of a main engine; C, for a permanent magnet synchronous traction machine, obtaining the output torque sum at the same horizontal position; and D, obtaining the balance coefficient. The rapid calculation method has the beneficial effects that the clip-on ammeter is used for measuring and recording the current when the elevator ascends and descends in a no-load mode till the lift car and the counterweight are located at the same horizontal position, and the related parameters of the elevator traction machine are combined, so that the balance coefficient can be solved and judged rapidly, a theoretical basis is provided for on-site mounting, debugging, inspection and maintenance personnel to rapidly diagnose the safety state of the elevator, and manpower, material resources and financial resources are saved.
