Chapter Outline
2. Regardless, actual costs frequently differ from standard costs;
differences often due to more than one factor.
a. Actual quantity used (of direct labor hours or direct materials) may
differ from standard.
b. Actual price paid per unit (of direct labor or direct materials) may
differ from standard.
B. Setting Standard Costs
1. Due to inefficiencies and waste, materials may be lost as part of
process.
a. An ideal standard is the quantity of material required if process
was 100% efficient without any loss or waste.
b. A practical standard is the quantity of material required under
normal application of process; allowance for loss included in
standard.
c. Most companies use practical standards.
2. A standard cost card shows the standard costs of direct materials,
direct labor, and overhead for one unit of product or service.
.
III. Cost VariancesCost variance (or simply variance) is difference between
actual and standard costs; can be favorable (if actual cost is less than standard
cost) or unfavorable (if actual cost is more than standard cost). Note that short–
term favorable variances can lead to long-term unfavorable variances.
A. Cost Variance Analysis
1. Variances are commonly identified in performance reports.
2. Management examines circumstances to determine factors causing the
variance; analysis, evaluation, and explanation involved.
3. Results of efforts should allow assignment of responsibility for the
variance; actions can then be taken to correct problems.
4. Four steps involved in proper management of variance analysis.
a. Preparation of standard cost performance report.
b. Computation and analysis of variances.
c. Identification of questions and their explanations.
d. Corrective and strategic action.
B. Cost Variance ComputationCost variance (CV) equals difference
between actual cost (AC) and standard cost (SC).
1. Actual quantity (AQ ) Standard quantity (SQ)
x Actual price (AP) x Standard price (SP)
Actual Cost (AC) Standard Cost (SC)
2. Actual quantity is input (material or labor) used in manufacturing the
quantity of output, and Standard Quantity is the input expected for the
quantity of output.
3. Actual Price is amount paid for acquiring the input (material or labor),
and Standard Price is the expected price.
