What is the unit product cost under absorption costing?3. What is operating income under absorption costing?

(1) $3,740

(2) $10.20

(3) $3,540

Explanation:

(1) Contribution Margin:

= Revenue - Variable expense

= (2,100 * $14) - (Direct material + Direct labor + variable overhead + variable selling expense)

= $29,400 - ($8,400 + $6,720 + $2,100 + $840)

= $29,400 - $18,060

= $11,340

Total fixed expense = Fixed overhead + Fixed Selling & Administrative expense

= $4,000 + $3,600

= $7,600

Operating income under variable costing:

= Contribution Margin - Total fixed expense

= $11,340 - $7,600

= $3,740

(2) Unit product cost under absorption costing:

= Direct material + Direct labor + Variable overhead + Fixed overhead

= $4 + $3.20 + $1 + (4,000 : 2,000)

= $4 + $3.20 + $1 + $2

= $10.20

(3) Gross margin = Revenue - cost of goods sold

= $29,400 - (2,100 * $10.20)

= $29,400 - $21,420

= $7,980

Total selling and Administrative expense:

= Variable selling + Fixed selling

= $840 + $3,600

= $4,440

Operating income under absorption costing:

= Gross margin - Total selling and Administrative expense

= $7,980 - $4,440

= $3,540
