A combination weighing device includes: a storage unit that stores time-series measurement values sequentially acquired by the measurement hoppers; a time measurement unit that measures an elapsed time from a timing corresponding to supply of the products to the measurement hoppers until a timing at which the time-series measurement values enter a region considered to be stabilized when the time-series measurement values stored in the storage unit converge to the region considered to be stabilized as a stabilization time until the measurement values become stabilized; and a selection unit that acquires the stabilization times by the time measurement unit over a plurality of cycles and can select a recommended stabilization time that is the stabilization time in which a predetermined measurement accuracy can be maintained based on a standard deviation of the acquired stabilization times for the plurality of cycles.
