1. Dr. Mohamed A. Hamada Lecturer of Accounting Information Systems 1-1 Chapter 3 Job-order costing systems

2. 2 JOB-ORDER COSTING: Definition An accounting system that assigns costs to products that are produced for specific jobs.

3. 3 JOB-ORDER COSTING The key feature of job-order costing is that the cost of 1 job differs from that of another and must be tracked separately.

4. 4 PROCESS COSTING: Definition An accounting system that assigns costs to products that are produced in a series of processes.

5. 5 PROCESS COSTING The key feature of process costing is that the products produced are homogeneous and therefore have the same cost.

6. 6 How do you calculate costs for a job-order cost system? Combine direct materials + direct labor + overhead Costs.

7. 7 Job 001 Materials cost $1,780 Direct labor $300 (20 hours x $15) Overhead $240 (20 hours x $12) Job 001 Materials.......... $1,780 Labor............. 300 Overhead.......... 240 Total.............. $2,320 Unit cost ($2,320/200) $11.60

8. So, Job-Order Costing Job-order costing systems are used when: 1.Many different products are produced each period. 2.Products are manufactured to order. 3.The unique nature of each order requires tracing or allocating costs to each job, and maintaining cost records for each job.

9. Job-Order Costing: Examples of companies that would use job-order costing include: 1.Boeing (aircraft manufacturing) 2.Bechtel International (large scale construction) 3.Walt Disney Studios (movie production) Examples of companies that would use job-order costing include: 1.Boeing (aircraft manufacturing) 2.Bechtel International (large scale construction) 3.Walt Disney Studios (movie production)

10. Job No. 1 Job No. 2 Job No. 3 Charge direct material and direct labor costs to each job as work is performed. Job-Order Costing – An Example Direct Materials Direct Labor

11. Manufacturing Overhead, including indirect materials and indirect labor, are allocated to all jobs rather than directly traced to each job. Job-Order Costing – An Example Direct Materials Direct Labor Job No. 1 Job No. 2 Job No. 3 Manufacturing Overhead Allocation Base

17. Why Use an Allocation Base? An allocation base, such as direct labor hours, direct labor dollars, or machine hours, is used to assign manufacturing overhead to individual jobs. We use an allocation base because: a.It is impossible or difficult to trace overhead costs to particular jobs. b.Manufacturing overhead consists of many different items ranging from the grease used in machines to the production manager’s salary. c.Many types of manufacturing overhead costs are fixed even though output are changed during the period.

18. The predetermined overhead rate (POHR) used to apply overhead to jobs is determined before the period begins. Manufacturing Overhead Application

19. Using a predetermined rate makes it possible to estimate total job costs sooner. Actual overhead for the period is not known until the end of the period. The Need for a POHR

20. Computing Predetermined Overhead Rates The predetermined overhead rate is computed before the period begins using a four-step process. 1.Estimate the total amount of the allocation base that will be required for next period’s estimated level of production. 2.Estimate the total fixed manufacturing overhead cost for the coming period and the variable manufacturing overhead cost per unit of the allocation base.

21. Computing Predetermined Overhead Rates 3- Use the following equation to estimate the total amount of manufacturing overhead: 4- Compute the predetermined overhead rate. Y = a + bX Where, Y = The estimated total manufacturing overhead cost a = The estimated total fixed manufacturing overhead cost b = The estimated variable manufacturing overhead cost per unit of the allocation base X = The estimated total amount of the allocation base.

22. Overhead Application Rate AB-Co estimates that it will require 160,000 direct labor-hours to meet the coming period’s estimated production level. In addition, the company estimates total fixed manufacturing overhead at $200,000, and variable manufacturing overhead costs of $2.75 per direct labor hour. Estimate POHR Solution

23. Overhead Application Rate POHR = $4.00 per direct labor-hour $640,000 estimated total manufacturing overhead 160,000 estimated direct labor hours (DLH) POHR = Y = a + bX Y = $200,000 + ($2.75 per direct labor-hour × 160,000 direct labor-hours) Y = $200,000 + $440,000 Y = $640,000 Y Estimated total manufacturing overhead cost for the coming period
