Vollkostenrechnung: Grundlagen und Aspekte

Definition and Purpose

• Vollkostenrechnung (full cost accounting) is a costing method that considers all costs incurred in the production of a product or service.
• It assigns both direct and indirect costs to products or services.
• The purpose is to determine the total cost of production and thus the selling price.
• It provides a comprehensive view of the costs associated with each product or service.
• It helps in decision-making regarding pricing, profitability analysis, and cost control.

Components of Vollkostenrechnung

• Direct Costs: Costs directly traceable to a specific product or service, like direct materials and direct labor.
• Indirect Costs: Costs not directly traceable to a specific product or service, allocated based on a chosen basis (e.g., machine hours, direct labor hours). Examples include factory rent, supervision salaries, and utilities.
• Fixed Costs: Costs remaining constant regardless of production level, like rent and administrative salaries.
• Variable Costs: Costs changing proportionally with production level, such as raw materials and direct labor.

Types of Vollkostenrechnung

• Absorption Costing: The most common type, including all manufacturing costs (direct and indirect, fixed and variable) in the product cost. These costs are absorbed by the product.
• Variable Costing: A variation including only variable manufacturing costs in product cost. Fixed manufacturing costs are treated as period costs.

Advantages of Vollkostenrechnung

• Comprehensive Cost Information: Provides a complete picture of all production-related costs.
• Accurate Costing: Potentially more accurate cost determination due to wider cost coverage.
• Compliance with Generally Accepted Accounting Principles (GAAP): Often required for financial reporting.

Disadvantages of Vollkostenrechnung

• Can Overstate Costs: Indirect cost allocation might not accurately reflect actual usage.
• Potential Distortion: Fixed cost allocation can distort profitability picture for different products based on sales volume and/or capacity utilization.
• Limited Use for Decision-Making: May not perfectly reflect costs directly linked to a specific decision, hindering short-term decision analysis.

Cost Allocation Methods

• Direct Method: Allocates indirect costs based on direct link to departments or products, e.g., a machine used solely for one product absorbs all its cost.
• Step-Down Method: Allocates costs prioritizing some departments, then distributes remaining costs to other departments based on relationships.
• Activity-Based Costing (ABC): Allocates costs based on activities rather than just volume, a more refined technique.

Applications of Vollkostenrechnung

• Pricing Decisions: Assessing total costs to determine a suitable selling price that covers costs and yields a profit.
• Profitability Analysis: Evaluating individual product or service profitability by comparing full costs to revenues.
• Cost Control: Identifying cost reduction areas through efficiency improvements or cheaper materials.

Relationship to other Costing Methods

• Comparison to Variable Costing: Often contrasted to variable costing.
• Integration with other Managerial Accounting Tools: Often used with other accounting methods for a holistic business performance view.

Reporting and Interpretation

• Cost Statements: Reports showing detailed cost components for each product or service.
• Profit and Loss Statement: Shows overall revenues, costs, and profits based on product or overall.
• Interpretation of Results: Analyzing cost statements and P&L to identify trends, assess profitable/unprofitable products, and support corrective actions.
