Chapter 24—Standard Cost Systems
Financial and Managerial Accounting, 18e 24-3
Comments and Observations
Teaching Objectives for Chapter 24
1. Explain the basic purpose of a standard cost system.
2. Distinguish between ideal and normal standards and explain the significance of this
distinction to the process of developing standard costs.
3. For each of the six cost variances described in the chapter:
a. Explain the nature of the variance
b. Discuss possible causes and the manager most likely responsible
c. Review the computation of the variance
d. Illustrate the journal entry to record the variance and related standard cost
4. Discuss the merits of valuing inventory and the cost of goods sold at standard cost,
with cost variances shown separately, compared with valuing inventory and the cost
of goods sold at actual cost.
5. Describe the year-end disposition of the balances in the variance accounts.
6. Discuss the inherent limitations of a standard cost system.
General Comments
Cost control is critical to the competitive position of a business and has thus
received considerable attention in the academic and professional literature. Despite the
popularity of just-in-time approaches to the management of costs, we believe traditional
standard cost systems and control via cost variances to be relevant and of vital importance.
It is important to establish the nature of a standard cost system at the outset.
Students have difficulty appreciating that standard costing is not an alternative to job-order
or process systems, but a variant of those systems. We always spend class time
distinguishing among actual, normal, and standard costs in both job-order and process
environments.
In covering standard costs, we find that some students fail to associate standard
costs with the flow of manufacturing costs through a cost accounting system. Rather, they
view the computation of cost variances as calculations made independently of the recording
function. Problems 3 through 8 and Case 2 are designed to show that standard costs are
indeed an integral part of the cost accounting system. To reinforce this point, you may
wish to call to students’ attention the fact that the use of standard costs in a process cost
system eliminates the need for tedious calculations of cost per equivalent unit, since
standard cost is the cost per equivalent unit. Again, Problem 4 makes this point nicely.
In covering standard costs it is crucial not to focus solely upon mechanics.
Whenever we compute a variance, we believe that it is important to discuss the nature and
the probable cause of that variance. Exercises 5 and 6 and Case 1 are all designed to focus
upon the interpretation of cost variance information. Finally, we recommend an in-class
review of Exercise 7. On the surface, this exercise appears quite mechanical. Actually, it is
both conceptual and comprehensive in nature. Students able to explain their answers to
this exercise have acquired a thorough understanding of “cost variances.”
