Procedure of Factory Overheads Including Apportionment

The procedure for managing factory overheads, including apportionment, involves several systematic steps to ensure accurate allocation and control of indirect manufacturing costs. Here’s a detailed overview of the process:

Steps in Managing Factory Overheads

1. Identification of Overhead Costs:

   • List All Overhead Costs: Identify all indirect costs related to manufacturing, such as indirect materials, indirect labor, utilities, depreciation, rent, insurance, maintenance, and property taxes.

2. Classification of Overhead Costs:

   • Variable vs. Fixed Costs: Classify costs as variable (changing with production levels) or fixed (constant regardless of production).
   • Direct vs. Indirect Costs: Identify which costs can be directly linked to production versus those that cannot.

3. Estimation of Overhead Costs:

   • Budgeting: Estimate the total factory overhead costs for the upcoming period based on historical data, planned production levels, and expected changes in costs.
   • Consider Seasonality: Adjust estimates based on expected fluctuations in production or costs during different times of the year.

4. Determining the Cost Driver:

   • Select Appropriate Activity Base: Choose a cost driver (e.g., labor hours, machine hours, units produced) that reflects the relationship between overhead costs and production activity.
   • Calculate the Predetermined Overhead Rate:
   $$\text{Predetermined Overhead Rate} = \frac{\text{Estimated Total Overhead Costs}}{\text{Estimated Total Units of Activity}}$$

5. Apportionment of Factory Overhead:

   • Allocate Costs to Cost Centers: Distribute overhead costs among different departments or cost centers (e.g., assembly, packaging) based on relevant criteria (e.g., square footage, number of employees).
   • Use Allocation Bases: Apply appropriate allocation bases for each cost center, ensuring a fair distribution of shared costs. For instance:
     • Rent could be apportioned based on the area occupied by each department.
     • Utilities might be allocated based on machine hours used.

6. Application of Overhead Costs:

   • Calculate Applied Overhead: Once production occurs, apply the overhead costs to specific jobs or products based on the predetermined overhead rate and actual activity levels:
   $$\text{Applied Overhead} = \text{Predetermined Overhead Rate} \times \text{Actual Units of Activity}$$

7. Recording and Tracking Overhead Costs:

   • Maintain Accurate Records: Keep detailed records of actual overhead expenses incurred and compare them to applied overhead to monitor variances.
   • Journal Entries: Record factory overhead costs in the accounting system, typically under a "Factory Overhead" account.

8. Variance Analysis:

   • Compare Actual vs. Applied Overhead: Analyze any variances between actual overhead costs and applied overhead.
   • Investigate Significant Variances: Identify the causes of variances (e.g., changes in utility rates, unexpected repairs) and take corrective actions if necessary.

9. Reporting:

   • Generate Overhead Reports: Produce regular reports summarizing overhead costs, variances, and their impact on overall production costs.
   • Provide Insights for Management: Use reports to inform management decisions regarding budgeting, pricing, and operational efficiency.

Conclusion

The procedure for managing factory overheads, including apportionment, is essential for accurate product costing and effective financial management in manufacturing. By systematically identifying, classifying, estimating, apportioning, and tracking overhead costs, organizations can ensure they have a clear understanding of their manufacturing expenses. Regular variance analysis and reporting further enhance the ability to control costs and make informed decisions, ultimately contributing to improved profitability and operational efficiency.
