Abstract: The information processing device determines whether or not to re-lease the first vehicle after returning from the lease. The information processing device includes a control unit. The control unit is configured to acquire, for the first vehicle, a evaluation result of a state according to a predetermined evaluation method, and output that the first vehicle is to be leased again when the evaluation result indicates that the first vehicle does not require repair, and output that the first vehicle is to be sold when the evaluation result indicates that the first vehicle needs repair.

Abstract: A controller is provided which is configured to: output, as lease plans for a new vehicle, a first plan in which an initial cost is incurred but a premature cancellation fee is not incurred and a second plan in which an initial cost is not incurred but a premature cancellation fee is incurred; and output only the first plan as a lease plan for a used vehicle.
