However, estimating does not involve predicting or forecasting instead it only involves quantifying for an interval of time. Traditionally, overheads have been absorbed in the product cost based on a single basis of apportionment. For instance, in a labor-intensive environment, labor hours were used to absorb overheads. On the other hand, the machine hours were used to absorb overheads in a machine incentive environment. Predetermined overhead is an estimated rate used by the business to absorb overheads in the product cost, and it’s calculated by dividing overheads by the budgeted level of activity.

Hence, one of the major advantages of predetermined overhead rate formula is that it is useful in price setting.

Hence, this is a compromise on the accuracy of the overall allocation process. On the other hand, the ABC system is more complex and requires extensive administrative work.

A later analysis reveals that the actual amount that should have been assigned to inventory is $48,000, so the $2,000 difference is charged to the cost of goods sold. Using a predetermined overhead rate allows companies to apply manufacturing overhead costs to units produced based on an estimated rate, rather than actual overhead costs. This rate is then used throughout the period and adjusted at year-end if necessary based on actual overhead costs incurred.
