Mellon Co. produces a single product with the following information available:
Number of units produced annually 25,000 Variable costs per unit:
Direct materials, direct labor and variable mfg. overhead 10$ Selling & administrative expenses 3$
Fixed costs per year:Mfg. overhead 150,000$Selling & administrative expenses 100,000$

Unit product cost is determined as follows:
Absorption Costing
Variable Costing
Direct materials, direct labor, and variable mfg. overhead 10$ 10$ Fixed mfg. overhead ($150,000 ÷ 25,000 units) 6 - Unit product cost 16$ 10$

Selling and administrative expenses are always treated as period expenses and
deducted from revenue.

Reconciling Income Under Reconciling Income Under Absorption and Variable CostingAbsorption and Variable Costing
We can reconcile the difference between absorption and variable net income as follows:
Variable costing net income 90,000$ Add: Fixed mfg. overhead costs deferred in inventory (5,000 units × $6 per unit) 30,000 Absorption costing net income 120,000$
Fixed mfg. overhead $150,000 Units produced 25,000
= $6.00 per unit =

Cost-Volume-Profit AnalysisCost-Volume-Profit Analysis
• CVP includes all fixed costs to compute breakeven. – Variable costing and CVP are consistent as both
treat fixed costs as a lump sum.
• Absorption costing defers fixed costs into inventory.– Absorption costing is inconsistent with CVP
because absorption costing treats fixed costs on a per unit basis.
