Today’s proponents of capacity accounting say that it
addresses two main concerns of traditional costing systems
that derive their predetermined overhead rates
based on estimated or budgeted activity in the coming
period. First, because the predetermined overhead rate
is based on “actual” capacity, it will not fluctuate from
period to period with budgeted activity. Second, products
are only charged for the portion of the resources
they actually use; therefore, they are not unduly burdened
in the marketplace
