The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Standard Cost Systems Chapter 23 The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Benchmarks for measuring performance. The expected level of performance. Based on carefully predetermined amounts. Used for planning labor, material and overhead requirements. Standard Costs are Standard Cost Systems The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Direct Material Type of Product Cost Amount Direct Labor Manufacturing Overhead Standard cost A standard cost variance is the amount by which an actual cost differs from the standard cost. Standard Cost Systems The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Type of Product Cost Amount This variance is unfavorable because the actual cost exceeds the standard cost. This variance is favorable because the actual cost is less than the standard cost. Standard cost Standard Cost Systems Direct Labor Manufacturing Overhead Direct Material The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Prepare standard cost performance report Conduct next periods operations Analyze variances Identify questions Receive explanations Take corrective actions Begin Variance Analysis The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Should we use normal standards or ideal standards? Engineer Managerial Accountant Establishing and Revising Standard Costs Normal standards should be set at levels that are currently attainable with reasonable and efficient effort. Production manager The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin I agree. Ideal standards, that are based on perfection, are unattainable and therefore discouraging to most employees. Human Resources Manager Establishing and Revising Standard Costs The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Are standards the same as budgets? A standard is the expected cost for one unit. A budget is the expected cost for all units. Use of Standard Costs in Developing Budgets The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Use product design specifications. Use competitive bids for the quality and quantity desired. Quantity Standards Direct Material Standards Price Standards The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin The standard material cost for one unit of product is: standard quantity standard price for of material one unit of material required for one unit of product Direct Material Standards The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Time Standards Rate Standards Direct Labor Standards Use time and motion studies for each labor operation. Use wage surveys and labor contracts. The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin The standard labor cost for one unit of product is: standard number standard wage rate of labor hours for one hour for one unit of product Setting Direct Labor Standards The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Activity Standards Rate Standards Manufacturing Overhead Standards The activity is the cost driver used to calculate the overhead rate. The rate is based on an estimate of total overhead at the normal level of activity. The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin The standard overhead cost for one unit of product is: standard variable standard number overhead rate for of activity units one unit of for one unit of activity product Manufacturing Overhead Standards The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Standard Cost Variances Quantity VariancePrice Variance A General Model for Variance Analysis The difference between the actual price and the standard price The difference between the actual quantity and the standard quantity The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Standard price is the amount that should have been paid for the resources acquired.

You purchased cheap material, so my people had to use more of it. Responsibility for Material Variances You used too much material because of poorly trained workers and poorly maintained equipment. Also, your poor scheduling sometimes requires me to rush order material at a higher price, causing unfavorable price variances. The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Lets turn our attention to labor variances. Labor Rate and Efficiency Variances The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Hanson Inc. has the following labor standard to manufacture one Zippy: 1.5 standard hours per Zippy at $8.00 per hour Payroll records last week show 1,450 hours were worked at a total labor cost of $11,890 to make 1,000 Zippies that were completed on May 15.

Production managers who make work assignments are generally responsible for rate variances. Labor Rate Variance The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Unfavorable Efficiency Variance Poorly trained workers Poor supervision of workers Poor quality materials Poorly maintained equipment Labor Efficiency Variance The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin I am not responsible for the unfavorable labor efficiency variance! You purchased cheap material, so it took more time to process it. You used too much time because of poorly trained workers and poor supervision. Responsibility for Labor Variances The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Maybe I can attribute the labor and material variances to personnel for hiring the wrong people and training them poorly. Responsibility for Labor Variances The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Lets turn our attention to manufacturing overhead Manufacturing Overhead Variances The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Recall that overhead costs are applied to products and services using a predetermined overhead rate (POHR): POHR = Applied Overhead = POHR Standard Activity Estimated total overhead costs Estimated activity Manufacturing Overhead Variances The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Overhead Rate Contains variable overhead that increases as activity increases. Contains fixed overhead that remains constant as activity changes. Function of activity level chosen to determine rate. Manufacturing Overhead Variances The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Hanson, Inc. has the following manufacturing overhead at three different levels of activity: Hanson applies overhead based on machine hour activity. Manufacturing Overhead Variances Example Zippy The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Overhead Variances Question 1 Zippy The total overhead rate for an estimated activity of 3,000 machine hours (MH) is: a. $5.00 per machine hour. b. $4.00 per machine hour. c. $3.00 per machine hour. d. $2.00 per machine hour. The total overhead rate for an estimated activity of 3,000 machine hours (MH) is: a. $5.00 per machine hour. b. $4.00 per machine hour. c. $3.00 per machine hour. d. $2.00 per machine hour.

Contains both fixed and variable costs. A controllable variance. The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Budgeted Applied Actual Overhead at Overhead at Overhead Actual Activity Standard Hours Spending Variance Volume Variance Manufacturing Overhead Variances Caused by producing at a level other than that used for computing the standard overhead rate. Contains only fixed costs. The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Hansons actual production for the period was 1,600 Zippies resulting in 3,200 standard machine hours. Actual total overhead cost for the period was $15,450. Compute the overhead spending and volume variances. Manufacturing Overhead Variances Example Zippy The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Budgeted Applied Actual Overhead at Overhead at Overhead Standard Hours Standard Hours $15,450 $9,000 fixed 3,200 hrs. + $6,400 variable $5.00 per hr. $2.00 per hr. 3,200 hrs.

Material Amounts Close by apportioning to: Disposing of Variances The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Advantages Improved cost control and performance evaluation. Better information for planning and decision making. Possible reductions in production costs. Advantages of Standard Costs The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin Disadvantages Emphasis on negative exceptions may impact morale. Emphasis on negative exceptions may lead to under-reporting. It may be difficult to determine which variances are significant. Disadvantages of Standard Costs The McGraw-Hill Companies, Inc., 2002 McGraw-Hill/Irwin JIT systems may reduce unfavorable variances. Long-term agreements with suppliers eliminate price variances. Emphasis on quality reduces material quantity variances. Well-trained flexible work force reduces labor efficiency variance.
