How to Apportion Overhead Costs





Overhead Costs: An Overview


Overhead costs are indirect expenses that support the overall operations of a business but cannot be directly attributed to specific products or services. These costs are essential for running a business, but they don't directly contribute to generating revenue.


Common Examples of Overhead Costs


  • Administrative salaries: Salaries of administrative staff, such as human resources, accounting, and legal personnel.

  • Rent and utilities: Costs associated with the physical space of the business, including rent, electricity, water, and heating.

  • Insurance: Business insurance premiums, such as liability, property, and workers' compensation.

  • Depreciation and amortization: Costs associated with the wear and tear of fixed assets (like equipment) and the gradual reduction in the value of intangible assets (like patents).

  • Property taxes: Taxes levied on the business's real estate.

  • Legal and professional fees: Costs related to legal advice, accounting services, and other professional services.

  • Advertising and marketing: Costs associated with promoting the business and its products or services.

  • Travel and entertainment: Expenses related to business travel, conferences, and client entertainment.

  • Office supplies: Costs of stationery, printing, and other office consumables.


Why Overhead Costs Matter


Understanding and managing overhead costs is crucial for several reasons:


  • Profitability: High overhead costs can significantly reduce a business's profitability.

  • Pricing: Overhead costs must be considered when setting product or service prices to ensure adequate profit margins.

  • Cost control: Effective overhead management can help businesses identify areas for cost reduction and improve overall efficiency.

  • Decision-making: Overhead costs are essential for making informed decisions about resource allocation, investments, and business strategy.


Apportioning Overhead Costs


To accurately determine the cost of products or services, businesses must apportion overhead costs to those items. This involves allocating a portion of the total overhead costs to each product or service based on a specific basis, such as direct labor hours, machine hours, or revenue.


What is Meant by Apportionment of Overhead


Apportionment of overhead is the process of allocating indirect costs, also known as overhead costs, to different departments, products, or services within a business. These indirect costs are expenses that cannot be directly traced to specific products or services, such as rent, utilities, salaries of administrative staff, and depreciation of fixed assets.


By apportioning overhead costs, businesses can:


  • Determine product costs: This is crucial for pricing decisions and profitability analysis.

  • Evaluate departmental performance: Apportioned overhead costs can be used to assess the efficiency and effectiveness of different departments.

  • Make informed decisions: Understanding the distribution of overhead costs can help businesses make better decisions regarding resource allocation and cost management.


There are several methods for apportioning overhead costs, including:


  • Direct labor hours: Allocates overhead based on the number of direct labor hours worked by each department.

  • Direct labor costs: Allocates overhead based on the total direct labor costs incurred by each department.

  • Machine hours: Allocates overhead based on the number of machine hours used by each department.

  • Square footage: Allocates overhead based on the amount of floor space occupied by each department.

  • Revenue: Allocates overhead based on the revenue generated by each department.


The choice of method depends on the specific circumstances of the business and the nature of its overhead costs.


Apportioning Overhead Costs: A Guide


Overhead costs are indirect expenses that support the overall operations of a business but cannot be directly attributed to specific products or services. Examples include rent, utilities, salaries of administrative staff, and depreciation of fixed assets.   


To ensure accurate pricing and profitability, it's essential to allocate these costs to various departments or products. This process is known as overhead apportionment.   


Methods for Apportioning Overhead Costs


Here are some common methods used:


  1. Direct Labor Hours:


    • Basis: The number of direct labor hours worked in each department.

    • Best for: Businesses where labor is a significant driver of overhead costs.


  2. Direct Labor Costs:


    • Basis: The total direct labor costs incurred by each department.

    • Best for: Businesses where labor costs vary significantly across departments.


  3. Machine Hours:


    • Basis: The number of machine hours used by each department.   

    • Best for: Manufacturing businesses where machinery is a major factor in overhead costs.   


  4. Square Footage:


    • Basis: The amount of floor space occupied by each department.

    • Best for: Businesses where overhead costs are primarily related to the physical space occupied by departments (e.g., rent, utilities).


  5. Revenue:


    • Basis: The revenue generated by each department.

    • Best for: Service-based businesses where revenue is a good indicator of resource consumption.


Steps to Apportion Overhead Costs


  1. Identify Overhead Costs: Determine the total overhead costs for the period.

  2. Select a Basis: Choose the most appropriate basis for apportionment based on your business's specific circumstances.

  3. Gather Data: Collect the necessary data for each department (e.g., direct labor hours, machine hours, square footage, revenue).

  4. Calculate Apportionment Rates: Divide the total overhead costs by the total of the chosen basis (e.g., total direct labor hours).

  5. Allocate Overhead: Multiply the apportionment rate by the relevant data for each department to determine its share of overhead costs.


Example: Direct Labor Hours


Scenario: A manufacturing company has two departments: Production and Administration. The total overhead costs for the period are $100,000. The Production department worked 10,000 direct labor hours, and the Administration department worked 2,000 direct labor hours.


Calculation:


  • Apportionment rate = Total overhead costs / Total direct labor hours = $100,000 / 12,000 hours = $8.33 per direct labor hour

  • Production department overhead = 10,000 hours * $8.33/hour = $83,300

  • Administration department overhead = 2,000 hours * $8.33/hour = $16,700


Note: It's important to review and adjust your apportionment methods regularly to ensure they accurately reflect your business's changing circumstances.


What is an example of basis of apportionment?


A basis of apportionment is the criteria used to allocate overhead costs to different departments, products, or services within a business. It's essentially the metric or measure that determines how much overhead each unit should bear.


Here are some common examples of bases of apportionment:


  • Direct labor hours: This is often used in manufacturing businesses where the amount of labor involved in producing a product is a significant factor in overhead costs.

  • Direct labor costs: Similar to direct labor hours, this basis considers the total cost of direct labor used for a product.

  • Machine hours: In businesses that rely heavily on machinery, the number of machine hours used to produce a product can be a suitable basis.

  • Square footage: For departments or products that occupy different amounts of physical space, the square footage they use can be used as a basis.

  • Revenue: This is often used in service-based businesses where the amount of revenue generated by a product or service is a good indicator of the resources consumed.


Example: A manufacturing company produces two products, A and B. Product A requires 10 direct labor hours to produce, while Product B requires 5 direct labor hours. If the company's total overhead costs for the period are $100,000 and the total direct labor hours are 1,000, the overhead apportionment rate would be $100 per direct labor hour ($100,000 / 1,000 hours).


  • Product A's overhead cost would be 10 hours * $100/hour = $1,000.

  • Product B's overhead cost would be 5 hours * $100/hour = $500.


In this case, direct labor hours is the basis of apportionment.
