# Predetermined Overhead Rate & Total Cost

Tanner Bay Inc. has two departments, Assembly and Packaging. The company uses a job order costing system and computes a predetermined overhead rate in each department. The Assembly Department bases its rate on machine hours and the Packaging Department bases its rate on direct labor hours. At the beginning of the year, the company made the following estimates:

Assembly Packaging
Direct labor hours 3,000 4,000
Machine hours 8,500 9,900
Manufacturing Overhead cost \$144,500 \$172,000
Direct labor cost \$89,200 \$101,000

Assume also the following actual data on Job #503 which was started and completed during the year:

Assembly Packaging
Direct labor hours 23 37
Machine hours 109 142
Materials requisitioned \$8,787 \$6,566
Direct labor cost \$2,100 \$1,990

What is the predetermined overhead rate to be used in each department?

XYZ Corporation has two departments, Machining and Assembly. The company uses a job order costing system and computes a predetermined overhead rate in each department. The Machining Department bases its rate on machine hours and the assembly Department bases its rate on direct labor cost. At the beginning of the year, the company made the following estimates:

Machining Assembly
Direct labor hours 11,000 9,000
Machine hours 23,000 14,000
Manufacturing Overhead cost \$368,000 \$312,000
Direct labor cost \$102,100 \$78,000

Assume also the following actual data on Job #219 which was started and completed during the year:

Machining Assembly
Direct labor hours 104 98
Machine hours 189 290
Materials requisitioned \$33,400 \$44,200
Direct labor cost \$4,200 \$9,600

What is the total cost assigned to job #219?
