Chapter 19

Learning Goals

  • Understand basic concepts in job costing.

  • Explore information systems for job costing environments.

  • Learn how to track job costs in the corporate ledger.

  • Understand accounting for actual and applied overhead.

  • Examine job costing in service, not-for-profit, and governmental environments.

  • Develop knowledge on modern management of costs and quality.


Cost Accounting Systems

  • Job Costing: Ideal for unique/custom products or projects.

    • Examples: Custom homes, services for clients, hospitals.

  • Process Costing: Used for homogeneous products that flow through processes.

    • Examples: Beverages, petroleum products.

  • Operations Costing: A hybrid system using aspects of both job costing and process costing.

    • Examples: Auto manufacturing, clothing manufacturing.

  • Activity Based Costing (ABC): A supplemental costing system allocating costs to various activities driving costs.

Job Costing Concepts

  • Job costing is suitable when goods/services are produced based on customer orders and specifications.

  • Each job is somewhat unique; materials and labor are easily traced.

    • Example: A shipbuilder collects costs per ship produced.

Job Costing Example: Castle Electric

  • Jack Castle's company indicates various job assignments to electricians on arrival.

  • Jack’s pay is $25/hour; tasks include inspections, permits, and inventory management.

Specific Tasks on July 14

  1. Job A: Cleaning and reconnecting electrical connections.

    • Materials: 1 lamp costing $150.

  2. Job B: Replacing breakers on an electrical panel.

    • Materials: 20 breakers at $20 each.

  3. Job C: Pulling wire for a new residence.

    • Materials: 500 feet of wire at $0.14/foot.

Employee Details

  • Donnie Odom: Electrician paid $18/hour working 1 hour on Job A, 2 on Job B, 3 on Job C, and 2 on indirect tasks.

  • Additional materials: Electrical tape ($3), wire nuts (60 nuts at $0.05 each).

  • Tools and equipment also contribute to job overhead costs.

Job Costing Components

  • Direct Costs:

    • Direct labor (Donnie's time, materials).

    • Direct materials (lamp, breakers, wire).

  • Indirect Costs (Overhead):

    • Includes shop expenses, equipment, and administrative time.

Tracking Job Costs

  • Labor Costs: Tracked through time reports documenting job durations.

  • Material Costs: Tracked on materials requisition forms, indicating what was put into production.

  • Overhead Costs: Difficult to trace; usually applied at the beginning of the year using predetermined rates.

    • Example: Jack estimated $150,000 for overhead and 7,500 direct labor hours.

    • Overhead Rate Calculation: $150,000/7,500 hours = $20 per direct labor hour.

Job Cost Sheets

  • Daily time sheets and material requisitions inform job cost sheets.

  • Information compiled includes direct labor, direct materials, and calculated overhead.

Job Costing and Technologies

  • A shift to electronic databases enhances job cost tracking, reduces input errors, and facilitates report generation.

  • Unique identifiers (serial numbers, barcodes) enhance tracking of direct materials.

Cost Drivers

  • Factors that cause costs to be incurred, need careful selection for allocating overhead costs effectively.

Corporate Ledger Overview

  • Costs flow through accounting systems as:

    1. Raw Materials → Work in Process → Finished Goods → Cost of Goods Sold.

    2. Tracking of job costs includes ensuring accuracy with actual versus applied overhead.

Applying Overhead

  • Overapplied: Indicates less spending than anticipated—favorable.

  • Underapplied: Indicates more costs incurred than applied—unfavorable.

    • Underapplied overhead often requires adjustment to cost accounts.

Job Costing in Different Environments

  • Applicable across sectors, including private, non-profit, and governmental entities.

  • Overhead allocation becomes increasingly critical in less tangible jobs.

Modern Management Practices**

  • Emphasis on metrics such as quality, customer satisfaction, and employee involvement.

  • Systems like Kaizen, Lean Manufacturing, and Total Quality Management (TQM) enhance cost management and efficiency.

Kaizen method

  • An approach focusing on continuous improvement from employees for efficiency gains.

Lean Manufacturing

  • Aims to trim waste and improve response time and customer value.

Just in Time (JIT) inventory management

  • Ensures raw materials arrive as needed, minimizing stock and potential obsolescence.

Six Sigma

  • Strategy focused on achieving near-zero defects in processes and products.
