3. To help identify factors causing the total overhead cost variance managers will analyze the
variance separately for volume and controllable variances.
a. The controllable variance is the difference between the actual total overhead costs incurred
4. Analyzing overhead controllable and volume variances
a. An unfavorable volume means the company did not reach its expected operating level – a
5. Overhead Variance Reports
a. Help managers isolate the reasons for a controllable variance.
b. Shows specific overhead costs and how they differ from budgeted amounts
VIII. Decision Analysis⎯Sales Variances⎯Similar to computation and analysis of cost variances.
A. Sales price variance and sales volume variance can be computed. Managers use sales variances for
planning and control purposes.
1. Sales price variance measures the impact of the actual sales price differing from the expected
IX. Expanded Overhead Variances
A. Computing Overhead Cost Variances⎯assume predetermined rate is based on relation between
standard overhead and standard labor hours.
1. Framework uses classifications of overhead costs as either variable or fixed
2. Exhibit 21A.1 shows that the variable overhead spending and efficiency variances and the fixed
overhead spending variance are combined to get the controllable variance.
