How to Compute Various Overhead Cost Variances Formula

The fixed overhead production volume variance is favorable because the company produced and sold more units than anticipated. If actual overhead costs amount to $11,000, the fixed overhead budget variance is $1000, meaning the company is $1000 over budget in overhead costs that month. If, for example, 1,000 units were produced that month, and $10 of overhead cost is assigned to each unit, the calculation is done against the per-unit costs of $9 and $11, respectively. Either way, this overhead variance formula compares overhead costs from budget to actual, and it highlights to management if overhead costs are changing against expectations. Fixed overhead budget variance is the difference between the budgeted cost of fixed overhead and the actual cost of the fixed overhead that occurs in the production during the period.

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. 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 fixed overhead production volume variance is favorable
because the company produced and sold more units than
anticipated.

How to Interpret the Fixed Overhead Spending Variance

The fixed overhead volume variance looks at how the budgeted overhead costs might change when compared to budgeted overhead costs. The fixed overhead volume variance looks at the overhead variance in terms of the actual volume of units produced against the budgeted number of units produced. Both types of overhead variance formulas can help capture where extra costs are coming from. Companies use an overhead variance formula because they are required to assign a portion of the fixed overhead costs to each product. On the other hand, if the budgeted fixed overhead is less than the actual cost of fixed overhead that occurs during the period, the result is unfavorable https://accounting-services.net/fixed-overhead-spending-variance-accountingtools/.

The calculation of the sub-variances also doesn’t provide a meaningful analysis of fixed production overheads. For example, if the workforce utilized fewer manufacturing hours during a period than the standard, it is hard to imagine a significant benefit of calculating a favorable fixed overhead efficiency variance. The fixed overhead costs included in this variance tend to be only those incurred during the production process, such as factory rent, equipment depreciation, staff salaries, insurance of facilities and utility fees. Therefore, these variances reflect the difference between the standard cost of overheads allowed for the actual output achieved and the actual overhead cost incurred. Calculate the fixed overhead spending and production volume variances using the format shown in Figure 10.13 “Fixed Manufacturing Overhead Variance Analysis for Jerry’s Ice Cream”. Figure 10.14 summarizes the similarities and differences between
variable and fixed overhead variances.

However, the actual number of units produced is only 2,000, resulting in a total of $50,000 fixed overhead costs. An unfavorable fixed overhead budget variance results when the actual amount spent on fixed manufacturing overhead costs exceeds the budgeted amount. The fixed overhead budget variance is also known as the fixed overhead spending variance. Because fixed overhead costs are not typically driven by
activity, Jerry’s cannot attribute any part of this variance to the
efficient (or inefficient) use of labor. Instead, Jerry’s must
review the detail of actual and budgeted costs to determine why the
favorable variance occurred.

8 Fixed Manufacturing Overhead Variance Analysis

Fixed overhead capacity variance is the difference between absorbed fixed production overheads attributable to the change in number of manufacturing hours, compared to what was budgeted. This is the portion of volume variance that is due to the difference between the budgeted output efficiency and the actual efficiency achieved. However, the actual cost of fixed overhead that incurs in the month of August is $17,500. This type of variance is calculated separately for direct variable expenses and overhead variable expenses. Similarly, if the allocated volume is down to the number of machine hours and a company outsources some or all of its production, the budgeted amount of machine hours will be much less than expected. In case of fixed overhead, the budgeted and flexible budget figures are exactly the same.

Volume variance is further sub-divided into efficiency variance and capacity variance. There are a number of reasons why this can happen, aside from simply poor forecasting. If sales on a product are seasonal, production volumes on a monthly basis can fluctuate.

Common Types of Manufacturing Costs

Because fixed overhead costs are not typically driven by activity, Jerry’s cannot attribute any part of this variance to the efficient (or inefficient) use of labor. Instead, Jerry’s must review the detail of actual and budgeted costs to determine why the favorable variance occurred. For example, factory rent, supervisor salaries, or factory insurance may have been lower than anticipated. Further investigation of detailed costs is necessary to determine the exact cause of the fixed overhead spending variance. The expectation is that 3,000 units will be produced during a time period of two months.

† $140,280 is the original budget presented in the manufacturing overhead budget shown in Chapter 9 “How Are Operating Budgets Created?”. The flexible budget amount for fixed overhead does not change with changes in production, so this amount remains the same regardless of actual production. Fixed overhead efficiency variance is the difference between absorbed fixed production overheads attributable to the change in the manufacturing efficiency during a period. If production volume relies on the labor hours of workers and a company implements new efficient practices that reduce the number of hours needed to produce a product, more units will be made than budgeted.

However, if the manufacturing process reaches a step cost trigger point where a whole new expense must be incurred, this can cause a significant unfavorable variance. Also, there may be some seasonality in fixed overhead expenditures, which may cause both favorable and unfavorable variances in individual months of a year, but which cancel each other out over the full year. Other than the two points just noted, the level of production should have no impact on this variance. Fixed Overhead Variance is the difference of standard cost of fixed overhead and the actual cost of fixed overhead.

• Actual fixed overhead is the actual cost of fixed overhead that occurs during the period.
• Additionally, the salaries of management and supervisory staff that involve in the production may also change when there is a turnover in these positions.
• For example, if the workforce utilized fewer manufacturing hours during a period than the standard, it is hard to imagine a significant benefit of calculating a favorable fixed overhead efficiency variance.
• Similarly, if the allocated volume is down to the number of machine hours and a company outsources some or all of its production, the budgeted amount of machine hours will be much less than expected.
• Fixed Overhead Variance is the difference of standard cost of fixed overhead and the actual cost of fixed overhead.

This means that the company spends more on fixed overhead than the scheduled amount that it has in the budget plan for the period. Specifically, fixed overhead variance is defined as the difference between standard cost and fixed overhead allowed for the actual output achieved and the actual fixed overhead cost incurred. This is a cost that is not directly related to output; it is a general time-related cost. Specifically, fixed overhead variance is defined as the difference between Standard Cost and fixed overhead allowed for the actual output achieved and the actual fixed overhead cost incurred.
