Chapter 3 Job-Order Costing
LEARNING OBJECTIVES
After studying Chapter 3 , you should be able to:
· LO1 Compute a predetermined overhead rate.
· LO2 Apply overhead cost to jobs using a predetermined overhead rate.
· LO3 Compute the total cost and average cost per unit of a job.
· LO4 Understand the flow of costs in a job-order costing system and prepare appropriate journal entries to record costs.
· LO5 Use T-accounts to show the flow of costs in a job-order costing system.
· LO6 Prepare schedules of cost of goods manufactured and cost of goods sold and an income statement.
· LO7 Compute underapplied or overapplied overhead cost and prepare the journal entry to close the balance in Manufacturing Overhead to the appropriate accounts.
· LO8 ( Appendix 3A ) Understand the implications of basing the predetermined overhead rate on activity at capacity rather than on estimated activity for the period.
· LO9 ( Appendix 3B ) Properly account for labor costs associated with idle time, overtime, and fringe benefits.
BUSINESS FOCUS: Two Former College Students Succeeding as Entrepreneurs
When the University of Dayton athletic department needed 2,000 customized T-shirts to give away at its first home basketball game of the year, it chose University Tees to provide the shirts. A larger competitor could have been chosen, but University Tees won the order because of its fast customer response time, low price, and high quality.
University Tees is a small business that was started in February 2003 by two Miami University seniors—Joe Haddad and Nick Dadas (see the company's website at www.universitytees.com ). The company creates the artwork for customized T-shirts and then relies on carefully chosen suppliers to manufacture the product.
Accurately calculating the cost of each potential customer order is critically important to University Tees because the company needs to be sure that the price exceeds the cost associated with satisfying the order. The costs include the cost of the T-shirts themselves, printing costs (which vary depending on the quantity of shirts produced and the number of colors printed per shirt), silk screen costs (which also vary depending on the number of colors included in a design), shipping costs, and the artwork needed to create a design. The company also takes into account its competitors’ pricing strategies when developing its own prices. ▪

Understanding how products and services are costed is vital to managers because the way in which these costs are determined can have a substantial impact on reported profits, as well as on key management decisions.
A managerial costing system should provide cost data to help managers plan, control, and make decisions. Nevertheless, external financial reporting and tax reporting requirements often heavily influence how costs are accumulated and summarized on managerial reports. This is true of product costing. In this chapter we use absorption costing to determine product costs. In absorption costing , all manufacturing costs, both fixed and variable, are assigned to units of product—units are said to fully absorb manufacturing costs. In later chapters we look at alternatives to absorption costing such as variable costing and activity-based costing.
Most countries—including the United States—require some form of absorption costing for both external financial reports and for tax reports. In addition, the vast majority of companies throughout the world also use absorption costing in their management reports. Because absorption costing is the most common approach to product costing throughout the world, we discuss it first and then discuss the alternatives in subsequent chapters.
Job-Order Costing—An Overview
Under absorption costing, product costs include all manufacturing costs. Some manufacturing costs, such as direct materials, can be directly traced to particular products. For example, the cost of the airbags installed in a Toyota Camry can be easily traced to that particular auto. But what about manufacturing costs like factory rent? Such costs do not change from month to month, whereas the number and variety of products made in the factory may vary dramatically from one month to the next. Because these costs remain unchanged from month to month regardless of what products are made, they are clearly not caused by—and cannot be directly traced to—any particular product. Therefore, these types of costs are assigned to products and services by averaging across time and across products. The type of production process influences how this averaging is done.
Job-order costing is used in situations where many different products are produced each period. For example, a Levi Strauss clothing factory would typically make many different types of jeans for both men and women during a month. A particular order might consist of 1,000 boot-cut men's blue denim jeans, style number A312. This order of 1,000 jeans is called a job. In a job-order costing system, costs are traced and allocated to jobs and then the costs of the job are divided by the number of units in the job to arrive at an average cost per unit.
Other examples of situations where job-order costing would be used include large-scale construction projects managed by Bechtel International, commercial aircraft produced by Boeing, greeting cards designed and printed by Hallmark, and airline meals prepared by LSG SkyChefs. All of these examples are characterized by diverse outputs. Each Bechtel project is unique and different from every other—the company may be simultaneously constructing a dam in Zaire and a bridge in Indonesia. Likewise, each airline orders a different type of meal from LSG SkyChefs’ catering service.
Job-order costing is also used extensively in service industries. For example, hospitals, law firms, movie studios, accounting firms, advertising agencies, and repair shops all use a variation of job-order costing to accumulate costs. Although the detailed example of job-order costing provided in the following section deals with a manufacturing company, the same basic concepts and procedures are used by many service organizations.
IN BUSINESS: IS THIS REALLY A JOB?
VBT Bicycling Vacations of Bristol, Vermont, offers deluxe bicycling vacations in the United States, Canada, Europe, and other locations throughout the world. For example, the company offers a 10-day tour of the Puglia region of Italy—the “heel of the boot.” The tour price includes international airfare, 10 nights of lodging, most meals, use of a bicycle, and ground transportation as needed. Each tour is led by at least two local tour leaders, one of whom rides with the guests along the tour route. The other tour leader drives a “sag wagon” that carries extra water, snacks, and bicycle repair equipment and is available for a shuttle back to the hotel or up a hill. The sag wagon also transports guests’ luggage from one hotel to another.
