3. 3-3 vs. Job Costing Process Costing Units of output are distinctive (individual jobs, special orders). Each unit has a relatively high value. Costs can be traced feasibly to the units. Units of output are distinctive (individual jobs, special orders). Each unit has a relatively high value. Costs can be traced feasibly to the units. Units of output are homogeneous (mass production). Each unit has a very low value. Not feasible to trace costs to units. Units of output are homogeneous (mass production). Each unit has a very low value. Not feasible to trace costs to units. Evaluating Major Types of Product-Costing Systems

4. 3-4 vs. Job Costing Process Costing Costs are traced or assigned to individual jobs. Costs are traced to the process. Then an average cost per unit is calculated for the process. Operation Costing is a hybrid often used for batches of similar products with different types of materials. Evaluating Major Types of Product-Costing Systems

8. 3-8 Boss, Co. began May with $1,000 of costs in Work-in-Process (WIP) Inventory and $2,000 of completed units in Finished Goods Inventory. During May, Boss incurred $68,000 of production costs. Goods costing $62,000 were sent to Finished Goods during the month. Also, during May, goods costing $60,000 were sold. Using the Cost Flow Model, compute the ending inventory amounts for WIP Inventory and Finished Goods Inventory.

16. 3-16 We can determine Direct Materials Cost and Direct Labor Cost for a Job as we do the work. But we won’t know actual Overhead Cost until the end of the accounting period, so we apply overhead to the job using a Predetermined Overhead Rate. How Production Overhead is Assigned to Jobs

19. 3-19 Budgeted total manufacturing overhead cost for the coming year Budgeted total units in the allocation base for the coming period POHR = The predetermined overhead rate (POHR) used to apply overhead to jobs is determined before the period begins. Ideally, the allocation base is a cost driver that causes overhead. Use of Predetermined Overhead Rates

38. 3-38 Let’s return to Glass Creations and see what we should do if actual and applied overhead are not equal. Overhead Variance

39. 3-39 SOLUTION Applied Overhead = POHR × Actual Direct Labor Hours Applied Overhead = $30.00 per DLH × 13,000 DLH = $390,000 SOLUTION Applied Overhead = POHR × Actual Direct Labor Hours Applied Overhead = $30.00 per DLH × 13,000 DLH = $390,000 Assume Glass Creations’ actual overhead for the year was $370,000 for a total of 13,000 direct labor hours. How much total overhead was applied to jobs during the year? Use Glass Creations’ predetermined overhead rate of $30.00 per direct labor hour. Assume Glass Creations’ actual overhead for the year was $370,000 for a total of 13,000 direct labor hours. How much total overhead was applied to jobs during the year? Use Glass Creations’ predetermined overhead rate of $30.00 per direct labor hour. Overhead Variance

40. 3-40 Assume Glass Creations’ actual overhead for the year was $370,000 for a total of 13,000 direct labor hours. How much total overhead was applied to jobs during the year? Use Glass Creations’ predetermined overhead rate of $30.00 per direct labor hour. Assume Glass Creations’ actual overhead for the year was $370,000 for a total of 13,000 direct labor hours. How much total overhead was applied to jobs during the year? Use Glass Creations’ predetermined overhead rate of $30.00 per direct labor hour. SOLUTION Applied Overhead = POHR × Actual Direct Labor Hours Applied Overhead = $30.00 per DLH × 13,000 DLH = $390,000 SOLUTION Applied Overhead = POHR × Actual Direct Labor Hours Applied Overhead = $30.00 per DLH × 13,000 DLH = $390,000 Overhead is overapplied for the year by $20,000.

45. 3-45 Actual Costing, Normal Costing and Standard Costing Actual Costing? Normal Costing? Actual direct costs (material and labor) are assigned to jobs as incurred. Manufacturing overhead is assigned to jobs when the actual overhead amounts are known. Actual direct costs (material and labor) are assigned to jobs as incurred. Manufacturing overhead is assigned to jobs when the actual overhead amounts are known. Actual direct costs (material and labor) are assigned to jobs as incurred. Manufacturing overhead is applied to jobs by using predetermined overhead rates. Actual direct costs (material and labor) are assigned to jobs as incurred. Manufacturing overhead is applied to jobs by using predetermined overhead rates. Standard Costing? Standard direct costs (material and labor) are assigned to jobs using pre- determined rates. Manufacturing overhead is applied by using predeter- mined (standard) overhead rates. Standard direct costs (material and labor) are assigned to jobs using pre- determined rates. Manufacturing overhead is applied by using predeter- mined (standard) overhead rates.

50. 3-50 Job and Project Management Complex jobs require scheduling and progress evaluations. Gantt charts are used for scheduling major activities. Progress evaluations compare: budgeted and actual costs actual time and estimated time during the life of the project.

51. 3-51 The following conditions can lead to improper job costing: Misstating the stage of completion. Charging costs to the wrong Job. Misrepresenting the cost of jobs. Cost misrepresentation in “cost- plus” contracts. The following conditions can lead to improper job costing: Misstating the stage of completion. Charging costs to the wrong Job.

52. 3-52 Recording Job-Order Costs – Typical Accounting Entries Let’s look at summary journal entries for a job- order costing system. We’ll omit the numbers in order to focus on accounts.

53. 3-53 Raw material purchases are recorded in an inventory account. Cost Flows – Material Purchases

54. 3-54 Direct materials issued to a job increase Work in Process and decrease Raw Materials. Indirect materials used are charged to Manufacturing Overhead and also decrease Raw Materials. Cost Flows – Material Usage

55. 3-55 The cost of direct labor incurred increases Work in Process and the cost of indirect labor increases Manufacturing Overhead. Cost Flows – Labor

56. 3-56 In addition to indirect materials and indirect labor, other manufacturing overhead costs are charged to the Manufacturing Overhead account as they are incurred. Cost Flows – Actual Overhead

57. 3-57 Work in Process is increased when Manufacturing Overhead is applied to jobs. Cost Flows – Overhead Applied

58. 3-58 As jobs are completed, the cost of goods manufactured is transferred to Finished Goods from Work in Process. Cost Flows – Cost of Goods Manufactured

59. 3-59 When finished goods are sold, two entries are required: (1) to record the sale; and (2) to record Cost of Goods Sold and reduce Finished Goods. Cost Flows – Sales

60. 3-60 Nonmanufacturing costs (period expenses) are charged to expense as they are incurred. Cost Flows – Period Expenses
