Service Department Cost Allocation for Accurate Product Costing

Steps:

• Identify purpose: Service departments provide support; their costs must be allocated to production for full cost capture.
• Evaluate reason 1: Allocation enables total overhead pooling in production for absorption rate calculation (overhead ÷ activity base).
• Evaluate reason 2: Full costs post-allocation support break-even analysis (fixed costs ÷ contribution margin per unit).
• Select combination: Reasons 1 and 2 align with allocation's role in costing and planning; reason 3 is a general objective, not allocation-specific.

Why A is correct:

• Allocation ensures comprehensive overhead for absorption rates (reason 1) and total costs for break-even computation (reason 2), per cost accounting principles.

Why the others are wrong:

• B: Reason 3 is indirect; allocation targets costing accuracy, not direct revenue coverage.
• C: Reason 2 aids planning but isn't primary; ignores key absorption role of reason 1.
• D: Reason 3 alone overlooks allocation's core function in overhead rates and analysis.

Final answer: A
