Job Order Costing
1. Define and explain the meaning of a predetermined manufacturing overhead rate that is applied in a job-order costing system. The predetermined overhead rate is used for estimating the manufacturing overhead cost because companies cannot assign the actual overhead cost to specific job. From the case, Wall Decor uses a traditional job-order costing system.
The actual costs of direct materials and direct labor are charged to its specific jobs which are unframed prints, steel-framed with no matting prints, and wood-framed with matting prints. As mentioned, predetermined overhead rate is based on estimates rather than actual results.This is because the predetermined overhead rate is computed before the period begins and is used to apply overhead cost throughout the period. Wall Decor calculates this rate as total estimated manufacturing overhead cost divided by total estimated cost of prints. Then, companies use predetermined overhead rates to allocate manufacturing overhead costs to each unframed or framed print, based on the costs of the prints.

Manufacturing overhead is an indirect cost.This means that it is either impossible or difficult to trace these costs to a particular product. The actual overhead incurred may not relate to the cost of print for example, an unframed print would get a higher share of overhead cost due to its higher volume comparing to the framed print that require much effort but still get a lower share of overhead because its lower volume. 3.
