Percentage on Prime Cost: Detailed Definition

The Percentage on Prime Cost is a method used in absorption costing to allocate manufacturing overhead to the units produced during a specific accounting period. The prime cost consists of direct materials and direct labor—the primary costs directly attributable to manufacturing a product. The percentage on prime cost method calculates the overhead to allocate by applying a predetermined percentage to the total prime cost. This percentage is often derived from historical data or industry standards and helps in evenly distributing the overhead costs across different products.

Formula

\[ \text{Overhead Allocation} = \left( \frac{\text{Total Manufacturing Overhead}}{\text{Total Prime Cost}} \right) \times 100 \]

Examples

  1. Company A:

    • Direct Materials: $50,000
    • Direct Labor: $30,000
    • Manufacturing Overhead: $20,000
    • Total Prime Cost: $50,000 (Direct Materials) + $30,000 (Direct Labor) = $80,000
    • Overhead Allocation Percentage: \(\left( \frac{20,000}{80,000} \right) \times 100 = 25%\)

    Therefore, for every dollar of prime cost, $0.25 is allocated to overhead.

  2. Company B:

    • Direct Materials: $75,000
    • Direct Labor: $45,000
    • Manufacturing Overhead: $30,000
    • Total Prime Cost: $75,000 (Direct Materials) + $45,000 (Direct Labor) = $120,000
    • Overhead Allocation Percentage: \(\left( \frac{30,000}{120,000} \right) \times 100 = 25%\)

    Similarly, Company B applies a 25% overhead on prime costs, consistent with Company A.

Frequently Asked Questions

1. What is the primary purpose of using the percentage on prime cost for overhead allocation?

The primary purpose is to uniformly distribute manufacturing overhead costs to the units produced, ensuring that each product carries an appropriate share of the indirect costs associated with its production.

2. How is prime cost calculated?

Prime cost is calculated as the sum of direct materials and direct labor costs involved in the production of goods.

3. What are direct materials and direct labor?

Direct materials are the raw materials that can be directly traced to the finished product. Direct labor refers to the wages and other labor costs directly associated with the production of goods.

4. Why is historical data important in determining the overhead percentage?

Historical data provides a reliable basis for estimating future overhead rates, ensuring that the applied percentage reflects actual business experience and trends.

5. Can the overhead percentage change over time?

Yes, the overhead percentage can change based on fluctuations in manufacturing overhead costs, changes in production processes, and updates to direct materials and labor costs.

  • Manufacturing Overhead: Indirect factory-related costs that are incurred when producing a product, such as factory utilities, depreciation of equipment, and wages of indirect labor.

  • Prime Cost: The direct costs of production, consisting of direct materials and direct labor.
