Process Costing Systems A job order costing system estimates the costs of manufacturing products for different jobs required for specific customer orders –Applicable in organizations that treat each individual job as a single unit of output A process costing system is applicable when all units produced during a specified time frame are treated as one unit of output –Every unit made during the time period is essentially identical

15.  2003 Prentice Hall Business Publishing, PowerPoint supplement to Management Accounting, 4rd ed., Atkinson, Kaplan, and Young, prepared by Terry M. Lease, Ph.D., CPA, Sonoma State University 3-15 Determination Of Cost Driver Rates Determining realistic cost driver rates has become increasingly important in recent years –Support costs now comprise a large portion of the total costs in many industries Many firms now recognize that several different factors may be driving support costs rather than one or even two factors, such as direct labor or machine hours –Firms are now taking greater care in identifying which support costs should relate to what cost driver

16.  2003 Prentice Hall Business Publishing, PowerPoint supplement to Management Accounting, 4rd ed., Atkinson, Kaplan, and Young, prepared by Terry M. Lease, Ph.D., CPA, Sonoma State University 3-16 Cost Driver Rates All costs associated with a cost driver, such as setup hours, are accumulated separately –Each subset of total support costs that can be associated with a distinct cost driver is referred to as a cost pool Each cost pool has a separate cost driver rate The cost driver rate is the ratio of the cost of a support activity accumulated in the cost pool to the level of the cost driver for the activity –Activity cost driver rate = Cost of support activity / Level of cost driver

Lease, Ph.D., CPA, Sonoma State University 3-17 Stable Cost Driver Rates (1of 2) The cost of the support activity is the cost of the resources committed to the particular activity The level of the activity cost driver is the long- term capacity made available by the amount of resources committed to a support activity –The cost of a support activity, therefore, excludes fluctuations in costs caused by short-term adjustments such as overtime payments –The level of the support activity cost driver also excludes short-term variations in demand as reflected in overtime or idle time

Lease, Ph.D., CPA, Sonoma State University 3-18 Stable Cost Driver Rates (2of 2) The ratio shown in the previous equation is based on costs and cost driver levels, the rate remains stable over time: –It does not fluctuate as activity levels change in the short run –It does not change simply because of short- run changes in external factors that do not affect the efficiency or price of the activity resources

19.  2003 Prentice Hall Business Publishing, PowerPoint supplement to Management Accounting, 4rd ed., Atkinson, Kaplan, and Young, prepared by Terry M. Lease, Ph.D., CPA, Sonoma State University 3-19 Fluctuating Rates For example, if the rate for machine costs is based on quarterly cost driver levels instead of the normal levels: –The rate increases as the demand for the machine activity falls –The rate decreases as the demand increases In contrast, the cost driver rate based on costs and activity levels remains fixed throughout the year –Costs depend on the machine capacity made available and not on the season

20.  2003 Prentice Hall Business Publishing, PowerPoint supplement to Management Accounting, 4rd ed., Atkinson, Kaplan, and Young, prepared by Terry M. Lease, Ph.D., CPA, Sonoma State University 3-20 Problems With Fluctuating Rates Determination of cost driver rates based on short-term usage results in higher rates during periods of lower demand –Job costs appear to be higher during time periods when demand is lower –Bid prices based on estimated job costs are likely to be higher during periods of low demand when they probably should be lower –The higher bid price can further decrease demand, which in turn leads to higher cost driver rates and even higher prices Conversely, in periods when demand is high and capacity is short, job costs will appear to be lower, and bid prices will also be low

21.  2003 Prentice Hall Business Publishing, PowerPoint supplement to Management Accounting, 4rd ed., Atkinson, Kaplan, and Young, prepared by Terry M. Lease, Ph.D., CPA, Sonoma State University 3-21 Number of Cost Pools The number of cost pools can vary –Some German firms use over 1,000 The general principle is to use separate cost pools if the cost or productivity of resources is different and if the pattern of demand varies across resources The increase in measurement costs required by a more detailed cost system must be traded off against the benefit of increased accuracy in estimating product costs –If cost and productivity differences between resources are small, having more cost pools will make little difference in the accuracy of product cost estimates

Lease, Ph.D., CPA, Sonoma State University 3-22 Recording Actual Job Costs Job order cost accounting systems record costs actually incurred on individual jobs as they are produced –This process allows comparison of actual costs with the estimated costs Copies of all materials requisition notes and worker time cards are forwarded to the accounting department, which then posts them on a job cost sheet The system calculates total costs for the portion of the job completed The structure of the job cost sheet is similar to that of the job bid sheet –The direct materials and direct labor costs on the job cost sheet represent the job’s actual costs incurred
