4.2 Overhead Application and Allocation

Overhead costs are the unsung heroes of manufacturing. They're the indirect expenses that keep the factory running but can't be traced to specific products. Understanding these costs is crucial for accurate pricing and profitability analysis in job order costing systems.

Calculating and applying overhead involves estimating costs, choosing allocation bases, and using predetermined rates. This process helps distribute overhead fairly across jobs, enabling better cost control and decision-making. It's a balancing act that can impact financial statements and overall business performance.

• Overhead costs encompass indirect manufacturing expenses not directly traceable to specific jobs or products (factory rent, utilities, equipment depreciation)
• Crucial for accurate cost determination in job order costing systems allocating costs to individual jobs or products
• Enable informed pricing decisions and profitability analysis by providing comprehensive cost picture

Calculation of predetermined overhead rates

• Predetermined overhead rate formula: $\text{Estimated Total Overhead Costs} \div \text{Estimated Total Allocation Base}$
• Common allocation bases include direct labor hours, direct labor cost, machine hours, or units produced
• Process involves:
  1. Estimating total overhead costs for the period
  2. Selecting appropriate allocation base
  3. Estimating total quantity of chosen allocation base
  4. Dividing estimated overhead by estimated allocation base

Overhead Application and Analysis

Application of overhead to jobs

• Overhead applied by multiplying actual quantity of allocation base used by predetermined rate
• Applied overhead formula: $\text{Actual Quantity of Allocation Base} \times \text{Predetermined Overhead Rate}$
• Accounting entry: Debit Work in Process Inventory, Credit Manufacturing Overhead

Under-applied vs over-applied overhead

• Under-applied overhead occurs when actual overhead exceeds applied overhead, increasing cost of goods sold
• Over-applied overhead happens when applied overhead exceeds actual overhead, decreasing cost of goods sold
• Calculated as: $\text{Actual Overhead} - \text{Applied Overhead}$
• Disposition methods include prorating to Work in Process, Finished Goods, and Cost of Goods Sold or immediate write-off to Cost of Goods Sold
• Impacts financial statements by affecting inventory values on Balance Sheet and influencing gross profit and net income on Income Statement
