JOB ORDER COST 10 SYSTEMS AND OVERHEAD ALLOCATIONS

Transcription

1 Chapter JOB ORDER COST 10 SYSTEMS AND OVERHEAD ALLOCATIONS To explain the purposes of cost accounting systems. LO Cost Accounting Systems Cost Accounting Systems Determining unit manufacturing costs Planning and control functions Evaluate and reward employee performance Disclose inventories and cost of goods sold Cost accounting systems provide information supporting decisions making the business successful Cost accounting systems are the procedures and techniques used by management Assessing the efficiency and effectiveness of operations Providing products or services to customers Manage activities that consume resources Track resources consumed by products and services

2 To identify the processes for creating goods and services that are suited to job order costing. LO Used for production of large, unique, high-cost items. Built to order rather than mass produced. Many costs can be directly traced to each job. Typical job order cost applications: Special-order printing Building construction Also used in service industry Hospitals Law firms overhead (OH) Receive orders from customers Begin production materials Applied to each job using a predetermined rate (POHR) Schedule e jobs Order Ode materials labor THE JOB

3 s Job No. 1 Job No. 2 Job No. 3 Charge direct material and direct labor costs to each job as work is performed. s Job No. 1 Job No. 2 Job No. 3 Apply overhead to each job using a predeter- mined rate Application Rates To explain the purpose and computation of overhead application rates for job order costing. The predetermined overhead rate (POHR) used to apply overhead to jobs is determined before the period begins. POHR = Estimated total manufacturing overhead cost for the coming gperiod Estimated total units in the activity base for the coming period LO3 Ideally, the activity base is a cost driver that causes overhead.

4 Application Rates Application Rates Using a predetermined rate makes it possible to estimate total job costs sooner. $ Based on estimates, and determined before the period begins. applied = POHR Actual activity Actual overhead for the period is not known until the end of the period. Actual amount of the cost driver such as units produced, direct labor hours, or machine hours incurred during the period Application Rates Compuline, Inc., applies overhead based on direct labor hours. Total estimated overhead for the year is $360,000. Total estimated labor hours are 30,000. What is Compuline s predetermined overhead rate per hour? Application Rates Estimated total manufacturing overhead cost for the coming period POHR = Estimated total units in the allocation base for the coming period $360, POHR = 30,000 direct labor hours (DLH) POHR = $12.00 per DLH For each direct labor hour worked on a job, $12.00 of manufacturing overhead will be applied to the job.

5 To describe the purpose and the content of a job cost sheet. The primary document for tracking the costs associated with a given job is the job cost sheet. LO4 Let s investigate The Job Cost Sheet The Job Cost Sheet Oak and Glass Furniture Co. Job Cost Sheet 831 Oak and Glass Furniture Co.

We will use T-accounts and start with materials. Work in Process s Inventory (Job Cost Sheet) Purchases Indirect Mfg. Indirect

Effect of Closing to Cost of Goods Sold UNDERAPPLIED (Applied OH is less than actual OH) OVERAPPLIED (Applied OH is greater than actual OH) INCREASE Cost of Goods Sold DECREASE Cost of Goods Sold Now let s complete the goods and sell them.

Sold Applied Cost of Goods Sold To define overhead-related related activity cost pools and provide several examples. Cost of Goods Sold LO Activity-Based Costing (ABC) Activity-Based Costing (ABC) One of the most difficult tasks in computing accurate unit costs lies in determining the proper amount of overhead cost to assign to each job. Assigning overhead is difficult. I agree! Plantwide Rate Departmental Rates Activity-Based Costing Allocation

10 Activity-Based Costing (ABC) Activity-Based Costing (ABC) AAAA In the ABC method, we recognize that many activities within a department drive overhead costs. Identify activity cost pools and assign indirect costs to those pools. Central idea... Products require activities. Activities consume resources. AAAA B B C B B C The Benefits of ABC Identifying Cost Drivers More detailed measures of costs. Better understanding of activities. More accurate product costs for... Pricing decisions. Product elimination decisions. Managing activities that cause costs. Benefits should always be compared to costs of implementation. Most cost drivers are related to either volume or complexity of production. Examples: machine time, machine setups, purchase orders, production orders. Three factors are considered in choosing a cost driver: Causal relationship. Benefits received. Reasonableness.
