Question

Ontario, Inc, manufactures two products, Standard and Enhanced, and applies overhead on the basis of direct-labor hours. Anticipated overhead and direct-labor time for the upcoming accounting period are $800,000 and 25,000 hours, respectively. Information about the company's products follows. Standard: Estimated production volume, 3,000 units Direct-material cost, $25 per unit Direct labor per unit, 3 hours at $12 per hour Enhanced Estimated production volume, 4,000 units Direct-material cost, $40 per unit Direct labor per unit 4 hours at $12 per hour Ontario's overhead of $800,000 can be identified with three major activities: order processing ($150,000), machine processing ($560,000), and product inspection ($90,000). These activities are driven by number of orders processed, machine hours worked, and inspection hours, respectively. Data relevant to these activities follow. Machine Hours Worked 18,000 22,000 40.000 Orders Processed 300 200 500 Standard Enhanced Total Inspection Hours 2.000 8.000 10.000 Top management is very concerned about declining profitability despite a healthy increase in sales volume. The decrease in income is especially puzzling because the company recently undertook a massive plant renovation during which new, highly automated machinery was installed-machinery that was expected to produce significant operating efficiencies Required: 1. Assuming use of direct-labor hours to apply overhead to production, compute the unit manufacturing costs of the Standard and Enhanced products if the expected manufacturing volume is attained. tutu.hased costing, compute the unit manufacturing costs of the Standard and Enhanced products if the

Answer 1

1.

Predetermined overhead rate = Estimated overhead cost / Estimated direct labor hours

Predetermined overhead rate = $800,000 / 25,000 = $32 per hour

	Standard	Enhanced
Direct material	$75,000 (3,000*$25)	$160,000 (4,000*$40)
Direct labor	108,000 (3,000*3*$12)	192,000 (4,000*4*$12)
Applied overhead	288,000 (3,000*3*$32)	512,000 (4,000*4*$32)
Total manufacturing costs	$471,000	$864,000
Units produced	3,000	4,000
Manufacturing cost per unit	$157	$216
