2 Methods of Tracking Product Costs Process Costing Job Costing  Homogeneous products manufactured  Costs are traced or allocated to each process  Examples: Dog food, cereal, canned vegetables, bottles of beer  Manufactured to order  Costs are traced or allocated to jobs  Separate cost records for each distinct ‘job’ or batch  Examples: Patients, printing, buildings, patients, clients Operation Costing  For products with differing materials and similar processes  Material costs are traced while conversion costs are allocated Flow of costs is the same under all methods: RM → WIP → FG → CGS Flow of costs is the same under all methods: RM → WIP → FG → CGS

3 Overview of Job Costing  Also called job order costing  Appropriate for production of  Tangible items—ships, bridges, cabinets, etc.  Services—tax returns, lawn care, divorce cases, etc.  Involves costs accumulated by ‘job’ usually for a particular order or batch Normal costing used to apply MOH –Applied using a predetermined OH rate based on actual activity

Job Costing Accounting  General ledger  One WIP ‘control’ account  Subsidiary ledger  Used with job costing systems to track the individual job costs  Consists of multiple job cost sheets  One account/job cost sheet for each job  Used to track/capture costs of a job  Reconcile at end of period 4 Totals of all costs posted to each 'job' in the subsidiary ledger Total amounts posted to the control account in the general ledger =

Subsidiary Ledger  Individual costs are posted to each job in the WIP subsidiary ledger.  The total of direct material, direct labor, and overhead applied is posted to the WIP control account. 6 WIP Control WIP - Job 27 WIP - Job 28 WIP - Job 30 WIP - Job 31 1, , , , ,687 2,180 2, ,  The balance of the WIP control account must equal the balance of the jobs in the WIP subsidiary ledger.

Job Cost Example Direct labor cost14,800 $14.60 per hour Factory overhead$248,492 Machine hours8,875 machine hours 7 Direct materials requisitioned$400 Direct labor hours 70 $15.20 per hour Machine-hours42 machine hours Sanja Enterprises uses job costing and applies overhead based on machine hours. Sanja’s budgeted annual information follows: Actual data for Job #178 Actual direct labor cost for all jobs for the entire year totaled $220,200. Actual annual manufacturing overhead cost was $247,000. Actual machine hours for all jobs for the entire year totaled 96,050. Show the calculation of the total cost of Job 178. POHR = $248,492 8,875 = $28.00 per machine hour DM$ 400 DL (70 x $15.20) 1,064 MOH ($28 x 42) 1,176 Total job cost$2,640
