Question

The Work-in-Process inventory account of a manufacturing firm shows a balance of $3,960 at the end of an accounting period. The job cost sheets of two uncompleted jobs show charges of $640 and $440 for materials, and charges of $540 and $740 for direct labor. From this information, it appears that the company is using a predetermined overhead rate, as a percentage of direct labor costs, of:

Answer 1

Answer: 125%

Step-by-step explanation:

Manufacturing overhead = Predetermined overhead rate * Direct labor

Manufacturing Overhead

= Work in process balance - Direct labor - Direct materials

= 3,960 - 640 - 440 - 540 - 740

= $1,600

The rationale behind the above is that that the Work in process account is made up of Direct labor, material and overhead. The Overhead would therefore be the balance less the Direct material and labor.

Direct Labor = 540 + 740

= $1,280

Manufacturing overhead = Predetermined overhead rate * Direct labor

1,600 = Predetermined overhead rate * 1,280

Predetermined overhead rate = 1,600/1,280

= 1.25

= 125%
