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
and the budgeted total overhead costs based on a flexible budget; named because it refers to
activities usually under management control.
4. Analyzing overhead controllable and volume variances
a. An unfavorable volume means the company did not reach its expected operating level – a
favorable variance means the company operated at a greater than expected operating level
b. Main purpose of the volume variance to identify what portion of the total overhead variance
is cause by failing to meet the expected production level.
c. Often the reasons the failing to meet expected operating levels are due to factors (e.g.
customer demand) beyond employees’ control.
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
price.
2. Sales volume variance measures the impact of operating at a different capacity level than
predicted by the fixed budget.
B. When multiple products sold:
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.
