Ans :
Because overhead is not easily traceable back to a job, overhead must be divided among
the different jobs or products during the year. Dividing or allocating overhead to various
jobs is called overhead application. Three additional reasons to allocate overhead are
(1) the amount of overhead actually incurred may not be known at the time a job is
being worked on, (2) some overhead costs are seasonal and should be spread over
production for the entire year, and (3) fixed manufacturing overhead costs are not
related to the number of units products and should be spread among all units produced.
Overhead is applied using a predetermined overhead rate. The rate is calculated by
dividing the estimated overhead costs for the period by the total estimated application
base. Reasons why overhead does not equal actual overhead might be that the estimated
overhead failed to include some items that would be incurred or included some items
that should not be incurred, the application base was not appropriate (did not drive
overhead costs), or that unexpected actual overhead occurred. If manufacturing
overhead is over-applied or under-applied, the balance is closed at the end of the period
by increasing or decreasing Cost of Goods Sold if the amount is insignificant and
pro-rated among Work-in-Process, Finished Goods and Cost of Goods Sold if the
amount is large.
