Job Order Costing and Analysis Chapter 15 Job Order Costing and Analysis We begin this chapter by describing a cost accounting system. We then explain the procedures used to determine costs using a job order costing system. We conclude with a discussion of over-and underapplied overhead.

Job Order Production Process Costing Job Costing Chapter 16 Used for production of large, unique, or high-cost items. Built to order rather than mass produced. Many costs can be directly traced to each job. Job order costing is typically used by manufacturers of custom products or providers of custom services. The jobs must be large enough in scope and value to justify the accounting effort to trace costs to the jobs. Job order production can apply to both manufacturing and service companies. 15-2

Job Order Manufacturing Process Costing Job Costing Chapter 16 Typical job order cost applications: Special-order printing Building construction Also used in service industry Hospitals Law firms Here you see some examples where job order costing is used. Another example familiar to many of us is an automobile repair shop. When you take your car in for an inexpensive job like an oil change, you expect to be charged the cost of an oil change instead of an expensive engine repair. The shop’s accounting system must be able to handle multiple jobs with differing amounts of materials and labor costs that are incurred each day. 15-3

Job Order Production Activities Direct Materials Indirect Finished Goods Inventory (Balance Sheet) Factory Overhead Allocate Goods in Process Inventory Direct materials and direct labor are traced directly to jobs in the Goods in Process Inventory account. Indirect materials and indirect labor, along with other factory overhead costs, flow through the Factory Overhead account into Goods in Process. Completed jobs are transferred from the Goods in Process Inventory account to the finished goods inventory account. When the finished jobs are delivered to customers, the cost of these jobs becomes an expense on the income statement called cost of goods sold. Cost of Goods Sold (Income Statement) Indirect Direct Labor 15-4

Job Cost Sheet C 2 A job cost sheet is a separate record maintained for each job that is used to account for material, labor, and factory overhead costs for each job. The job cost sheet may be a paper record, but most likely it is a computerized file. Here’s an example of a job cost sheet showing customer identification, job number, relevant dates, along with materials, labor, and overhead expenditures for the job. 15-5

Materials Requisition P1 C. Luther When materials are needed for a job, the production manager, C. Luther, prepares a materials requisition and sends it to the materials manager. The materials manager, M. Bateman, will not release materials from the materials storage facility without this authorization. In addition to the proper signature authorizing the transfer of materials, the job number of the job where the material is to be used is noted on the requisition. Materials requisitions are sequentially numbered just like checks in a checkbook This feature enhances the control of materials use. The requisition also contains a description of the material along with the inventory stock number. When material is transferred from the materials storage facility, an accounting entry is made to reduce the material inventory balance. The materials requisition is the source document supporting the accounting entry, which we will see in a subsequent slide. M. Bateman C. Luther 15-6

Materials Ledger Card P1 The materials ledger card is a perpetual inventory record of the material M-347. This record may be a paper record, but most likely it is a computerized file. Here we see that $225 of material M-347 has been issued on materials requisition R4705. This entry on the ledger card reduces the inventory balance from $675 to $450. 15-7

Job Cost Sheet (Materials used) P1 Here we see the summary information for the material used on job B15 entered on the job cost sheet. If additional information about this material is needed, it can be found on materials requisition R4705. 15-8

Job Cost Sheet (Direct Labor used) P2 Accumulate direct labor costs by means of a work record, such as a time ticket, for each employee. Labor cost entered on the job cost sheet is summarized from an employee’s time ticket. Let’s see one 15-9

Labor Time Ticket C. Luther Road Warriors Time Ticket No. L-3479 P2 Road Warriors Time Ticket No. L-3479 Job No. B15 Date 3/8/13 Employee Name T. Zeller Employee Number 3969 TIME AND RATE INFORMATION: Start Time 9:00 Finish Time 12:00 Elapsed Time 3.0 Hourly Rate $20.00 Total Cost $60.00 Approved By Remarks Production managers use labor time tickets to assign labor costs to individual jobs. In addition to the proper signature authorizing the labor cost assignment, the time ticket includes labor time, rate, job number, date, and employee identification. Labor time tickets are the source documents supporting the payroll accounting entries. C. Luther 15-10

Job Cost Sheet (Direct Labor Cost) P2 Here we see the summary information for the labor cost of job B15 entered on the job cost sheet. If additional information about the labor cost is needed, it can be found on time ticket L3479. This will generate an accounting entry (to be shown later). 15-11

Job Cost Sheet (Factory Overhead) P3 Overhead is an indirect manufacturing cost that includes all production costs other than direct materials and direct labor. Entries for various overhead items will be shown on a subsequent slide. Unlike labor and materials, overhead cannot be traced directly to individual jobs. We must use a predetermined overhead rate to allocate overhead to jobs. The predetermined overhead rate may be based on such production factors as direct labor hours, direct labor cost, or machine hours Allocate manufacturing overhead to jobs using a predetermined overhead rate Let’s do it 15-12

Job Cost Sheet (Factory Overhead) P3 Road Warriors assigns overhead to jobs using a predetermined overhead rate of 160% of direct labor cost. In other words, for each dollar of direct labor incurred on a job, $1.60 of overhead will be charged to the job. For job B15, the labor cost was $1,000; so multiplying $1.60 times $1,000 yields $1,600 of overhead assigned to the job. 15-13

Predetermined Overhead Allocation Rate Formula Road Warriors uses a predetermined overhead rate (POHR) based on direct labor cost to apply overhead to jobs. Estimated total manufacturing overhead cost for the coming period Estimated total direct labor costs for the coming period POHR = POHR = = 160% of direct labor $ $200,000 $125,000 The term predetermined means that the overhead rate is computed before the operating period begins. Overhead costs and labor costs are estimated for the coming period as a part of the company’s budgeting process. The activity chosen for the denominator is known as an allocation base. Overhead and the allocation base are linked such that as the allocation base increases, overhead increases. For Road Warriors, we could say that overhead supports direct labor costs, or that incurrence of direct labor costs causes additional overhead costs. 15-14

Factory Overhead Account Cost Flows and Documents P1 The materials requisition indicates the cost of direct materials to charge to jobs and the cost of indirect materials to charge to overhead. Direct materials Job Cost Sheets Factory Overhead Account Materials Ledger Cards Materials Ledger Cards Materials Ledger Cards Materials Requisition Let’s look at two flow diagrams that will help us put job order document flows into perspective. Materials used are classified as either direct or indirect. We place direct materials’ costs on the job cost sheet. We place indirect materials costs in the Factory Overhead account. Later the overhead will be applied to the job using a predetermined overhead rate. Indirect materials 15-15

Factory Overhead Account Cost Flows and Documents P3 Direct Labor Employee time tickets indicate the cost of direct labor to charge to jobs and the cost of indirect labor to charge to overhead. Job Cost Sheets Job Cost Sheets Job Cost Sheets Job Cost Sheets Employee Time Ticket Employee Time Ticket Employee Time Ticket Employee Time Ticket Labor costs are also classified as either direct or indirect. We place direct labor costs on the job cost sheet. We place indirect labor costs in the Factory Overhead account. Later, factory overhead will be applied to the job using a predetermined overhead rate. Factory Overhead Account Indirect Labor 15-16

Summary of Cost Flows Material Purchases Direct Material Dr Cr Dr Cr Material Purchases Direct Material Actual Overhead Costs Indirect Material Dr Cr T-accounts for a job order system are helpful in visualizing the cost flows. Material purchases are entered as debits (left side) in the Raw Materials Inventory account. A credit entry (right side) in the Materials Inventory account is recorded when material is withdrawn. Direct materials usage is recorded in the Goods in Process Inventory account and on the job cost sheet for an individual job. Indirect material usage is recorded in the Factory Overhead account. 15-17

/ Summary of Cost Flows = Underapplied or Overapplied Overhead Direct Labor Direct Material Incurred Indirect Labor Actual Overhead Costs Overhead Overhead Applied to Work in Process Actual Applied factory factory overhead overhead = / an adjustment is needed. We will look at how to accomplish this later. When Direct labor and applied factory overhead are the remaining product costs that we must record. Direct labor cost is recorded in the goods in process inventory account and on the job cost sheet for an individual job. Indirect labor cost is recorded in the factory overhead account. Factory overhead is applied to jobs in the goods in process inventory account using a predetermined overhead rate. Because of the estimating process used in calculating the predetermined overhead rate, the amount of overhead assigned to all jobs in an operating period may differ from the actual overhead costs incurred in the same period. When actual factory overhead is different from the applied factory overhead, an adjustment will be needed to remove the balance in the Factory Overhead account. We will look at how to do this a little later in the presentation. 15-18

Direct Material Direct Labor Overhead Summary of Cost Flows P4 Direct Material Direct Labor Overhead Cost of Goods Mfd. Cost of Goods Sold Direct material, direct labor, and factory overhead amounts are transferred to goods in process. As jobs are completed, they are transferred to finished goods and then sold (delivered to customers). The dollar amount of the transfer from the Goods in Process Inventory account to the Finished Goods Inventory account is called cost of goods manufactured. 15-19

Reasons for using a predetermined overhead rate Overhead Application P4 Reasons for using a predetermined overhead rate Overhead is not incurred uniformly during the year. Actual overhead rate might vary from month to month. Predetermined rate makes it possible to estimate job costs sooner. We cannot wait until the end of the period when all actual overhead costs are known to charge overhead costs to jobs. Jobs are completed continually during the year. Perpetual inventory records must be updated in a timely manner, not at the end of the period. Customers expect to know the total cost of jobs at the time jobs are delivered, not at the end of the period. Using a predetermined overhead rate allows us to assign overhead in a timely and consistent fashion to accomplish these objectives. 15-20

Adjusting of Overapplied and Underapplied Overhead Overhead is overapplied. Overhead applied to Work in Process (POHR × Activity) Actual overhead costs incurred When the amount of overhead applied to all jobs in a period is greater than the actual amount of overhead incurred, overhead is overapplied. 15-21

Adjusting of Overapplied and Underapplied Overhead Overhead is underapplied. Actual overhead costs incurred Overhead applied to Work in Process (POHR × Activity) When the amount of overhead applied to all jobs in a period is less than the actual amount of overhead incurred, overhead is underapplied. 15-22

Adjusting of Overapplied and Underapplied Overhead Adjusting Cost of Goods Sold for underapplied or overapplied overhead If overhead is underapplied, the cost of goods sold does not include all production costs incurred. Therefore, the end-of-period adjustment for underapplied overhead increases cost of goods sold. If overhead is overapplied, the cost of goods sold includes more costs than were incurred. The end-of-period adjustment for overapplied overhead decreases cost of goods sold. 15-23

Job Order Costing Typical Accounting Entries The following journal entries illustrate the recording process for a job order cost system. To record material purchased on account, we increase the Raw Materials Inventory account with a debit entry and we increase Accounts Payable with a credit entry. 15-24

Job Order Costing Typical Accounting Entries When direct material is used, we decrease the Raw Materials inventory account with a credit entry. If the materials used are direct materials, we increase the Goods in Process Inventory account with a debit entry. If the materials used are indirect materials, we increase Factory Overhead with a debit entry. 15-25

Job Order Costing Typical Accounting Entries When salaries and wages are paid, we record the amount in the Factory Payroll account with a debit entry and we reduce Cash with a credit entry. 15-26

Job Order Costing Typical Accounting Entries The portion of factory payroll that is classified as direct labor increases the Goods in Process Inventory account while the portion that is indirect labor increases the Factory Overhead account. We record the increases to Goods in Process and to Factory Overhead with debit entries. 15-27

Job Order Costing Typical Accounting Entries Other actual costs for factory overhead items are recorded with a debit entry to the Factory Overhead account. Prepaid Insurance is an asset account that is reduced with a credit as the insurance coverage is used. Utilities Payable is a liability account that is increased with a credit. Raw Materials Inventory is an asset account that is reduced with a credit indicating that indirect materials were requisitioned into production. Accumulated Depreciation is a contra asset account that is increased with a credit to reflect the adjusting entry for depreciation on factory buildings and equipment. 15-28

Job Order Costing Typical Accounting Entries Factory overhead is applied to jobs using a predetermined overhead rate, resulting in an increase in the Goods in Process Inventory account. 15-29

Job Order Costing Typical Accounting Entries Completed goods are transferred from the Goods in Process Inventory account to the Finished Goods Inventory account. We record the increase in finished goods with a debit entry and we record the decrease in Goods in Process with a credit entry. 15-30

Job Order Costing Typical Accounting Entries When the goods are sold, we reduce the Finished Goods Inventory account with a credit entry. Cost of Goods Sold is an expense account that is recorded with a debit entry. In addition to this, a company also needs to record the revenue generated on the sale. This would be accomplished through a debit to Cash or Accounts Receivable and a credit to Sales. 15-31

End of Chapter 15 Now that we have mastered some of the basic concepts of Job Order Cost Accounting, we are ready to move on to the next chapter. 15-32
