(2) Two-Stage Allocation: It can be observed that both the costing systems follow a two stage allocation procedure. In traditional costing, in the first stage, overhead costs are allocated to production departments. But in ABC, in the first stage, overhead costs are assigned to each major activity and not to departments.

Variable cost are those costs that varies according to level of production. In case of low production, it will be low and vice versa.
