Premier Products Contribution Margin and Overhead Allocation
This paper examines the contribution margin analysis for Premier Products, a manufacturer facing two production constraints that limit combined output across product lines. The analysis reveals that allocating overhead by direct labor hours significantly distorts the apparent profitability of each product, making Product A appear far less viable than it actually is. By comparing pro forma income statements under different production scenarios, the paper demonstrates that maximizing contribution margin alone does not guarantee overall profitability, and that the opportunity cost of producing one unit of Product A versus Product B is fundamentally misrepresented by the current allocation methodology.

What makes this paper effective
- Uses a concrete numerical example (pro forma income statements) to ground an abstract accounting concept, making the argument immediately verifiable.
- Identifies a specific, real flaw in the allocation methodology — misalignment between labor-hour-based overhead and actual production constraints — rather than making a generic critique.
- Clearly connects the allocation distortion to decision-making consequences: the wrong product appears most profitable, leading the firm toward a loss-generating strategy.
Key academic technique demonstrated
The paper demonstrates comparative scenario analysis: it constructs multiple pro forma income statements (All A, All B, All C, All D) and contrasts their outcomes to reveal that contribution margin rankings and actual profitability rankings diverge. This technique shows students how to use quantitative comparisons as evidence for a qualitative argument about methodology flaws.
Structure breakdown
The paper opens by defining the contribution margin and identifying the cost inputs. It then states the production constraints and the naive optimization conclusion. A pro forma comparison follows, showing that the naive approach produces losses. The paper then diagnoses the root cause — overhead allocation by labor hours — and quantifies the distortion at the unit level ($53 vs. $28.50). It closes by extending the logic to the C/D machine and briefly noting demand-side uncertainty if products are discontinued.
Introduction and Contribution Margin Framework
The contribution margin is revenue less variable costs. For Premier Products, the price of each product is known, as are the variable material costs and the direct labor rate of $5 per hour. The primary remaining question is how to allocate overhead, which the company assigns on the basis of direct labor hours. Understanding these inputs is essential before evaluating which products the company should prioritize.
Production Constraints and Profit Maximization
Premier Products faces two distinct production constraints. One machine can only be used to produce Product A or Product B; the other machine can only produce Product C or Product D. Given these constraints, a straightforward contribution margin analysis would suggest that the company should produce the product with the highest contribution margin on each machine — in this case, Product B on the first machine and Product D on the second, as both carry the highest contribution margin figures within their respective groups.
Pro Forma Income Statement Comparison
To assess the true impact on profits, the current profitability must be compared against the profitability that would result from the proposed product-mix change. A pro forma income statement provides this comparison. Assuming the company can sell everything it produces, the following scenarios emerge:
| All A | All B | All C | All D | |
|---|---|---|---|---|
| Revenue | $196,000 | $77,000 | $119,000 | $98,000 |
| Variable Costs | $90,000 | $20,000 | $50,000 | $30,000 |
| Contribution | $106,000 | $57,000 | $69,000 | $68,000 |
| Fixed Costs | $80,000 | $80,000 | $80,000 | $80,000 |
| EBITDA | $26,000 | –$23,000 | –$11,000 | –$12,000 |
What becomes immediately apparent is that optimizing solely for contribution margin leads the company to choose Product B and Product D — yet both of those scenarios produce a net loss. Only maximizing Product A results in a positive EBITDA. This outcome reveals a fundamental problem with relying on the contribution margin calculation as currently constructed.
The reason is that Product A is the only product that, when maximized, actually covers the company's fixed overhead. Product A is priced significantly higher than the others, so 2,000 units of Product A generate far more revenue than 2,000 units of any competing product. Since A and B are produced on the same machine — with total capacity fixed at 2,000 units — choosing B over A sacrifices a substantial amount of revenue for a product that cannot cover overhead on its own.
