This is one of the better cost accounting variances for management to review, since it highlights changes in costs that were not expected to change when the fixed cost budget was formulated. When the actual amount budgeted for fixed overhead costs based on production volume differs from the figure that is eventually absorbed, fixed overhead volume variance occurs. For Boulevard Blanks, the budgeted fixed overhead was $13,365 (notice the level of production does not matter since fixed costs remain the same regardless of volume) and the actual fixed overhead costs were $13,485. The company can calculate fixed overhead volume variance with the formula of standard fixed overhead applied to actual production deducting the budgeted fixed overhead. Fixed overhead volume variance is the difference between the amount budgeted for fixed overhead costs based on production volume and the amount that is eventually absorbed. This variance is reviewed as part of the cost accounting reporting package at the end of a given period.
- The fixed overhead production volume variance is favorable because the company produced and sold more units than anticipated.
- Overhead variances arise when the actual overhead costs incurred differ from the expected amounts.
- To obtain the fixed overhead volume variance, calculate the actual amount as (actual volume)(assigned overhead cost) and then subtract the budgeted amount, calculated as (budgeted volume)(assigned overhead cost).
Actual production volume is the production that the company actually achieves (in hours) or produces (in units) during the period. The figure in hours here can either be labor hours or machine hours depending on which one is more suitable for the measurement in the production. On the other hand, the budgeted production volume is the production volume that the company estimates to produce or achieve during the period. It is the normal capacity that the company or the existing facility can achieve for the period. This figure is usually included in the budget of production that is planned or scheduled before the production starts.

Financial and Managerial Accounting
Figure 10.14 summarizes the similarities and differences between
variable and fixed overhead variances. Notice that the efficiency
variance is not applicable to the fixed overhead variance
analysis. Total overhead cost variance can be subdivided into budget or spending variance and efficiency variance. Connie’s Candy used fewer direct labor hours and less variable overhead to produce 1,000 candy boxes (units).
4 Compute and Evaluate Overhead Variances
It is not necessary to calculate these variances when a manager cannot influence their outcome. In other words, FOH budget variance is the amount by which the total fixed overhead calculated as per the fixed overhead application rate exceeds or falls short of the actual total fixed overhead cost incurred for the period. In its New Jersey factory, the company budgets for the allocation what is the distinction between debtor and creditor of $75,000 of fixed overhead costs to produce the tiles at a rate of $25 per unit produced. The fixed manufacturing overhead volume variance is the difference between the amount of fixed manufacturing overhead budgeted to the amount that was applied to (or absorbed by) the good output. If the amount applied is less than the amount budgeted, there is an unfavorable volume variance.
What causes an unfavorable fixed overhead budget variance?
This could be for many reasons, and the production supervisor would need to determine where the variable cost difference is occurring to better understand the variable overhead efficiency reduction. Suppose Connie’s Candy budgets capacity of production at 100% and determines expected overhead at this capacity. Connie’s Candy also wants to understand what overhead cost outcomes will be at 90% capacity and 110% capacity.
The fixed factory overhead variance represents the difference between the actual fixed overhead and the applied fixed overhead. In a standard cost system, overhead is applied to the goods based on a standard overhead rate. The standard overhead rate is calculated by dividing budgeted overhead at a given level of production (known as normal capacity) by the level of activity required for that particular level of production.
Let’s assume that in 2022 DenimWorks manufactures (has actual good output of) 5,300 large aprons and 2,600 small aprons. Let’s also assume that the actual fixed manufacturing overhead costs for the year are $8,700. As we calculated earlier, the standard fixed manufacturing overhead rate is $4 per standard direct labor hour.
If the actual production volume is higher than the budgeted production, the fixed overhead volume variance is favorable. On the other hand, if the actual production volume is lower than the budgeted one, the variance is unfavorable. However, as the name suggested, it is the fixed overhead volume variance that is more about the production volume.
However, the variable standard cost per unit is the same per unit for each level of production, but the total variable costs will change. Recall that the standard cost of a product includes not only materials and labor but also variable and fixed overhead. It is likely that the amounts determined for standard overhead costs will differ from what actually occurs. The fixed overhead production volume variance is favorable because the company produced and sold more units than anticipated.
It is important to start by noting that fixed overhead in the
master budget is the same as fixed overhead in the flexible budget
because, by definition, fixed costs do not change with changes in
units produced. Thus budgeted fixed overhead costs of $140,280
shown in Figure 10.12 will remain the same even though Jerry’s
actually produced 210,000 units instead of the master budget
expectation of 200,400 units. The company can calculate the fixed overhead budget variance with the formula of budgeted fixed overhead cost deducting the actual fixed overhead cost. To calculate this overhead variance, start with the overhead rate charged to each unit. To obtain the fixed overhead volume variance, calculate the actual amount as (actual volume)(assigned overhead cost) and then subtract the budgeted amount, calculated as (budgeted volume)(assigned overhead cost).
