A process planning support apparatus according to an embodiment includes a setting unit (12), a first calculation unit (14), a second calculation unit (15), and an output unit (16). The setting unit (12) sets allocation of works with respect to each of work stations in an assembly line. The first calculation unit (14) calculates work times corresponding to work subjects of the work stations based on library data of each of unit works, in which each unit work is expressed by a combination of element works each having motions as constituent elements, for the works allocated to the work stations, respectively. The second calculation unit (15) calculates evaluation indexes of the work stations based on the calculated work times, respectively. The output unit (16) outputs the calculated evaluation indexes.
