This chapter provides a comprehensive overview of standard costs, including price and quantity standards for direct materials, direct labor, and overhead. It examines the importance of setting achievable standards—both ideal and practical—and discusses management by exception. The chapter details the calculations for various variances: materials price, quantity, labor rate, efficiency, and variable overhead spending. Challenges associated with standards, such as potential impacts on morale and quality, are also highlighted. With practical homework and review suggestions, this chapter serves as a valuable resource for mastering variance analysis.

Chapter 10 Standard Costs
Standard Costs • Price standards • Direct materials • Direct labor • Overhead • Quantity standards • Direct materials • Direct labor • Overhead • Management by exception • Ideal vs. practical standards
Setting Standards • Price/rate standards • Direct materials • Price of material • Freight/shipping • Discounts • Storage/handling • Direct labor • Labor rate per hour • Overtime • Benefits • Taxes • Paid time off
Setting Standards • Quantity/hours standards • Direct materials • Amount/Quantity used • Waste and spoilage • Rejects • Direct labor • Labor hours • Breaks • Downtime • Clean up • Rejects
Materials • Materials price variance AQ x AP – AQ x SP or AQ(AP – SP) • Materials quantity variance AQ x SP – SQ x SP or SP(AQ – SQ)
Labor • Labor rate variance AH x AR – AH x SR or AH(AR – SR) • Labor efficiency/hour variance AH x SR – SH x SR or SR(AH – SH)
Variable Overhead • Variable overhead spending/rate variance AH x AR – AH x SR or AH(AR – SR) • Variable overhead efficiency/hour variance AH x SR – SH x SR or SR(AH – SH)

Problems with Standards • Variances are often reported too late to be useful. • Standards can undermine morale. • Labor efficiency standards encourage high output. This may lead to excessive work in process inventory. • A favorable quantity variance may be worse than an unfavorable quantity variance. • Quality may suffer if undue emphasis is placed on just meeting the standards. • Just meeting standards may not be sufficient; continual improvement is often necessary.
