Percentage on Prime Cost: Absorbing Manufacturing Overhead

August 31, 2024 4 min read Accounting Finance Absorption Costing Manufacturing Overhead Prime Cost Cost Allocation Financial Planning

An essential accounting principle, the percentage on prime cost is a basis used in absorption costing for allocating manufacturing overhead into the cost units produced. Understanding this formula is crucial for accurate cost management and financial planning.

Introduction

The term “Percentage on Prime Cost” refers to a method used in absorption costing for allocating manufacturing overhead into the cost units produced. This basis is instrumental in determining the comprehensive cost of production, which includes direct materials, direct labor, and manufacturing overhead. The calculation helps companies set product prices accurately and manage costs effectively.

Historical Context

Absorption costing, also known as full costing, dates back to the early 20th century and became widely adopted as businesses sought more accurate ways to calculate product costs. The method ensures that all manufacturing costs are accounted for, providing a complete picture of product expenses.

Types/Categories

Absorption costing can be applied in different ways depending on the cost base used:

Percentage on Prime Cost: Overhead is allocated as a percentage of the prime cost.
Percentage on Direct Labor Cost: Overhead is absorbed based on direct labor expenses.
Percentage on Machine Hours: Overhead is distributed according to machine hours used.

Key Events

Key developments in absorption costing:

Early 1900s: Introduction of absorption costing methods.
1920s-1940s: Enhanced focus on cost accounting during industrial growth.
1980s: Adoption of activity-based costing as an alternative to absorption costing.

Detailed Explanations

Formula for Percentage on Prime Cost

\text{Percentage on Prime Cost} = \left( \frac{\text{Total Manufacturing Overhead}}{\text{Total Prime Cost}} \right) \times 100

Where:

Total Manufacturing Overhead includes all indirect costs of production.
Total Prime Cost comprises direct materials and direct labor costs.

Calculation Example

Suppose a manufacturing company has the following costs for a period:

Total Manufacturing Overhead: $50,000
Total Direct Materials Cost: $150,000
Total Direct Labor Cost: $100,000

\text{Total Prime Cost} = \text{Direct Materials Cost} + \text{Direct Labor Cost}

\text{Total Prime Cost} = \$150,000 + \$100,000 = \$250,000

\text{Percentage on Prime Cost} = \left( \frac{50,000}{250,000} \right) \times 100 = 20\%

This percentage (20%) is then applied to individual products’ prime costs to absorb the overhead.

Importance

Understanding and applying the percentage on prime cost is vital for several reasons:

Accurate Product Costing: Ensures all costs are included in product pricing.
Cost Control: Helps in identifying and managing manufacturing overheads.
Financial Reporting: Essential for compliance with accounting standards.

Applicability

The percentage on prime cost is applicable in various manufacturing and production environments where accurate cost allocation is essential. It helps businesses in:

Price setting
Cost analysis
Budgeting and forecasting

Considerations

When using the percentage on prime cost method:

Consistency: Apply the method consistently across periods for comparability.
Accuracy of Data: Ensure accurate collection of cost data.
Relevance: Regularly review the percentage to reflect changes in production processes or overhead costs.

Absorption Costing: A method that allocates all manufacturing costs to products.
Prime Cost: Sum of direct materials and direct labor costs.
Manufacturing Overhead: Indirect costs associated with production.

Comparisons

Absorption Costing vs. Variable Costing: Absorption costing includes fixed manufacturing overheads in product costs, while variable costing only includes variable costs.
Percentage on Prime Cost vs. Activity-Based Costing: Activity-based costing allocates overheads based on activities, offering more precise cost distribution.

Interesting Facts

Absorption costing is required by Generally Accepted Accounting Principles (GAAP) for external reporting.
Many companies initially resisted absorption costing due to its complexity compared to simpler methods.

Inspirational Stories

Many businesses have significantly improved their cost management and pricing strategies by adopting the percentage on prime cost. For instance, a small manufacturing company doubled its profit margins within two years by switching to absorption costing.

Famous Quotes

“Cost is more important than quality but quality is the best way to reduce cost.” — Genichi Taguchi

Proverbs and Clichés

“Cut your coat according to your cloth.”
“You get what you pay for.”

Expressions, Jargon, and Slang

Fixed Overhead: Costs that do not change with production levels.
Variable Overhead: Costs that vary directly with production levels.
Cost Pool: A grouping of individual costs from which cost allocations are made later.

FAQs

What is the main advantage of using the percentage on prime cost?

The primary advantage is that it provides a straightforward method to allocate overhead costs, ensuring all production costs are considered in pricing and financial analysis.

How often should the percentage on prime cost be reviewed?

It should be reviewed periodically, ideally annually, or whenever significant changes in production or cost structure occur.
