ABC Company sells 10,000 widgets. The company has no beginning or ending inventory. Using the absorption approach (GAAP) the net income of the company is as follows:

Sales (10,000 @ \$20) \$200,000
Cost of goods sold (10,000 @ \$12) 120,000
Gross profit \$ 80,000
Expenses 20,000
Net income \$ 60,000
Using the contribution margin approach the net income of the company is as follows:
Sales (10,000 @ \$20) \$200,000
Variable cost of goods sold (10,000 @ \$8) 80,000
Contribution margin \$120,000
Fixed expenses 60,000
Net income \$ 60,000
