The Managerial Accountant Are Asked B
Due 6/3/2020 1500 words you, the managerial accountant, are asked by the CFO (Mr. Smith) of Wilson–West Manufacturing (a new company) to set up a product costing system. The following are the types of expenses that will be included: Direct labor, Direct materials, Utilities, Depreciation, Maintenance, Insurance on the equipment, Rent on the plant, Administrative salaries, Rent for the office. In a memo format, explain to Mr. Smith and the president what will be included in product costing and what is involved in a product costing system. Explain why Wilson–West Manufacturing needs to have a product costing system. Allocate the above expenses as fixed, mixed, or variable expenses. Prepare calculations for the following, and explain your computations: Variable cost: The unit rate is $0.25, and the actual hours used for manufacturing are 15,000. Mixed cost: The unit rate is $0.25, actual hours are 10,000, and the fixed cost is $5,000 per month. Total cost: Use your calculations from above. Explain this to Mr. Smith who will prepare these calculations on a monthly basis.
Paper For Above instruction
Setting up an effective product costing system is crucial for Wilson–West Manufacturing, particularly as a new company aiming to establish accurate cost management and pricing strategies. In this memo, I will delineate what constitutes product costing, why it is essential, how to classify expenses into fixed, mixed, or variable categories, and will provide detailed calculations for the specific costs involved, to assist Mr. Smith in executing accurate monthly cost analyses.
Understanding Product Costing and Its Components
Product costing involves the accumulation and analysis of all costs associated with manufacturing a product, enabling management to establish product prices that cover costs and generate desired profit margins. These costs include direct costs such as materials and labor, and allocated indirect costs, known as manufacturing overhead. Overhead includes utilities, depreciation, maintenance, insurance, rent, and administrative expenses—costs that support production but are not directly traceable to a single product.
To implement an effective product costing system, Wilson–West Manufacturing must identify, quantify, and allocate all relevant costs accurately. This system will facilitate cost control, enable pricing competitiveness, and support financial reporting and strategic decision-making.
Necessity of a Product Costing System for Wilson–West Manufacturing

As a new manufacturing entity, Wilson–West needs a well-structured product costing system to determine the true cost of each product, improve profitability, and ensure sustainability. Such a system provides insights into cost drivers, highlights areas where efficiencies can be achieved, and supports budgeting and financial planning. Additionally, precise product costing aids in competitive bidding, inventory valuation, and identifying the most profitable product lines. Without a systematic approach, the company risks underpricing products or incurring unforeseen costs that erode margins.
Classification of Expenses: Fixed, Mixed, or Variable
Direct Materials and Direct Labor:
These are variable costs that fluctuate directly with production volume. As production increases or decreases, materials purchased and labor hours vary proportionally.
Utilities:
Usually variable, as utility consumption increases with increased production activity.
Depreciation:
Typically fixed, since depreciation expense remains constant regardless of production volume.
Maintenance:
Often mixed; part of maintenance costs are fixed based on scheduled maintenance, while some costs are variable depending on production levels.
Insurance on Equipment:
Usually fixed, with premiums often not changing with production volume.
Rent on the Plant:
Fixed, as rent payments are generally constant regardless of production fluctuations.
Administrative Salaries and Rent for the Office:
Fixed, as these costs do not vary with production output.
Cost Calculations and Explanations
1. Variable Cost Calculation

The variable cost per unit is $0.25. With actual manufacturing hours totaling 15,000, the total variable manufacturing cost is computed as:
Total Variable Cost = Variable Cost per Hour × Number of Hours
= $0.25 × 15,000 = $3,750
This cost reflects expenses that change directly in proportion to production activity, such as direct materials and direct labor.
2. Mixed Cost Calculation
The mixed cost includes a fixed component and a variable component. Given a fixed cost of $5,000 per month and a variable cost rate of $0.25 per hour for 10,000 hours, the total cost is calculated as:
Total Mixed Cost = Fixed Cost + (Variable Rate × Actual Hours)
= $5,000 + ($0.25 × 10,000)
= $5,000 + $2,500 = $7,500
This blended cost pattern captures expenses like maintenance, which have both fixed and variable characteristics.
3. Total Cost Computation
The total cost for manufacturing combines the variable and fixed components calculated above. Summing the two yields:
Total Cost = Total Variable Cost + Total Mixed Cost
= $3,750 + $7,500
= $11,250
This total encompasses all relevant manufacturing and overhead costs associated with the production period.
Implementation and Monthly Reporting

Mr. Smith will utilize these calculations monthly to monitor cost trends, evaluate efficiency, and inform pricing strategies. Accurate records of hours worked, cost components, and expense classifications will ensure reliable financial insights. Regular review and adjustment of cost rates are recommended to account for changes in input prices, overhead allocations, and operational efficiencies.
Conclusion
Establishing a comprehensive product costing system allows Wilson–West Manufacturing to accurately capture manufacturing expenses, support strategic decision-making, and maintain competitive advantages. Clear classification of expenses, precise cost calculations, and ongoing monitoring are essential components of this system. With these measures in place, Mr. Smith will be well equipped to prepare accurate monthly cost reports, enabling the company to achieve its financial goals.
