f) = No.
No. Companies use a predetermined application rate for
several reasons including the fact that manufacturing overhead is
not easily traced to jobs and products. The predetermined rate is
based on estimates of both overhead and an appropriate cost
driver, and these estimated rarely equal actual overhead incurred
or the actual cost driver activity. Under- or over-applied
overhead typically arises at year-end.

    Applying Manufacturing Overhead ApplyingManufacturing Overhead Manufacturing overhead is applied or added to each job while it is in process. There are three kinds of overhead costs consider: 1. 1. Estimated overhead cost Estimated overhead cost which is determined from the annual budget prepared before annual budget prepared before the year begins and is used only in the predetermined overhead rate calculation 2. 2. Actual overhead cost Actual overhead cost which is incurred incurred periodically periodically throughout the year and debited debited to the manufacturing overhead account 3. 3. Applied overhead cost Applied overhead cost which is added to jobs in the work-in-process inventor work-in-process inventory account throughout the year and credited credited to the manufacturing overhead account o The manufacturing overhead account is a holding account for the actual overhead costs (debits debits) and applied over costs (credits credits). 04/06/25 By Megersa H. 2023 17
