How are non-manufacturing costs accounted for in cost accounting?

Non-manufacturing costs, including administrative and selling expenses, are accounted for separately in cost accounting to accurately allocate and track overhead beyond production. These costs cover functions like marketing, management, or distribution and are allocated based on relevant cost drivers or activity-based costing methods. Properly accounting for non-manufacturing costs ensures a comprehensive view of total expenses, aiding in better decision-making and cost control strategies.


Non-manufacturing costs, also known as operating expenses or selling, general, and administrative (SG&A) expenses, are costs not directly associated with the production of goods. Cost accounting includes these costs in the overall cost structure of a business to assess profitability accurately. Here's how non-manufacturing costs are accounted for:

  1. Categorization: Non-manufacturing costs include various expenses such as selling expenses (e.g., advertising, sales commissions), general and administrative expenses (e.g., salaries, office rent, utilities), and other operating expenses (e.g., research and development, legal fees). These costs are categorized separately from manufacturing costs.

  2. Cost Allocation: Non-manufacturing costs are allocated to cost objects using different allocation bases. For example, sales commissions might be allocated based on sales revenue, office rent based on square footage, or administrative salaries based on the number of employees.

  3. Direct Attribution: Some non-manufacturing costs are directly attributed to specific cost objects without allocation. For instance, if advertising expenses are solely for promoting a particular product, those costs can be directly assigned to that product.

  4. Activity-Based Costing (ABC): ABC can be used to allocate non-manufacturing costs more accurately by identifying activities that drive these costs. This method ensures a more precise allocation based on the consumption of resources.

  5. Period Cost Recognition: Non-manufacturing costs are typically recognized as expenses in the period they are incurred rather than being inventoried as part of the cost of goods sold. They are expensed immediately on the income statement.

  6. Integration in Cost Analysis: Non-manufacturing costs are considered in various cost analyses, such as cost-volume-profit (CVP) analysis, where they influence breakeven points, contribution margins, and overall profitability.

  7. Overhead Allocation: In some cases, non-manufacturing costs may also be allocated as part of overhead expenses, impacting the overall cost structure and pricing decisions.

  8. Reporting and Analysis: Cost accounting includes non-manufacturing costs in performance reports and analyses, allowing managers to evaluate the total cost of operations and make informed decisions regarding resource allocation, pricing strategies, and cost control measures.

Accounting for non-manufacturing costs ensures a comprehensive understanding of the total cost structure of an organization. Proper allocation and analysis of these expenses are essential for accurate financial reporting, performance evaluation, and strategic decision-making.

Accounting for Overhead Beyond Production.

Accurately accounting for overhead costs beyond production is crucial for gaining a comprehensive picture of your organization's financial health and making informed decisions. Here are some key considerations and approaches:

1. Identifying and Classifying Overhead:

  • Identify non-production overhead: These are costs incurred that don't directly contribute to the production process, such as administrative expenses, marketing costs, research and development expenses, and facility costs.
  • Classify overhead: Categorize non-production overhead based on its behavior (fixed, variable, or semi-variable) and its allocation base (e.g., number of employees, floor space, revenue generated).

2. Allocation Methods:

  • Direct allocation: Assign non-production overhead directly to the cost object (department, product, project) that benefits from it. This is suitable for easily traceable costs.
  • Indirect allocation: Distribute non-production overhead based on a predetermined allocation base. Common methods include:
    • Floor space: Allocate based on the square footage occupied by each cost object.
    • Number of employees: Allocate based on the number of employees in each cost object.
    • Revenue generated: Allocate based on the revenue generated by each cost object.
  • Activity-based costing (ABC): Identify activities that drive non-production overhead and allocate costs to cost objects based on their consumption of those activities. This provides a more accurate picture of cost drivers compared to traditional allocation methods.

3. Cost Pools and Traceability:

  • Cost pools: Group similar non-production overhead costs into pools for easier allocation.
  • Traceability: Prioritize directly allocating overhead costs that can be easily traced to specific cost objects. Use indirect allocation methods for costs that are more difficult to trace.

4. Impact on Financial Statements:

  • Cost of goods sold (COGS): Production overhead is included in COGS, while non-production overhead is expensed in the period it is incurred.
  • Gross margin: Non-production overhead affects gross margin by reducing it.
  • Profitability analysis: Understanding the allocation of non-production overhead is crucial for accurately assessing the profitability of different departments, products, or projects.

Challenges and Solutions:

  • Choosing the right allocation method: There is no single "correct" method. Consider the complexity of your operations, the nature of your overhead costs, and the level of accuracy you need.
  • Data collection and maintenance: Accurate overhead allocation requires reliable data on cost drivers and allocation bases.
  • Regular review and updates: Review and update your overhead allocation methods periodically to ensure they remain relevant and accurate.

Benefits of Effective Overhead Accounting:

  • Improved decision-making: Accurate allocation of overhead costs leads to better informed decisions about pricing, resource allocation, and product mix.
  • Increased profitability: Identifying and managing non-production overhead can help optimize costs and improve profitability.
  • Enhanced transparency and accountability: Clear allocation of overhead costs fosters transparency and accountability within the organization.

By effectively accounting for overhead beyond production, you can gain a deeper understanding of your cost structure, identify areas for improvement, and ultimately make better decisions that drive profitability and long-term success.
