Variable Overhead Efficiency Variance Overview, Formula, Risk of Error

variable overhead efficiency variance

The standard overhead cost is usually expressed as the sum of its component parts, fixed and variable costs per unit. Note that at different levels of production, total fixed costs are the same, so the standard fixed cost per unit will change for each production level. However, the management should make sure to set the realistic standard or budget benchmarks taking into confidence the operations’ managers and the skilled labor. Most of the variable overheads correlate to the production changes, so the overhead variance should follow the same pattern.

Importance of Understanding Overhead Variance in Accounting and Business Management

In conclusion, the variable overhead rate variance can be an important factor in determining the total overhead variances, provided it is interpreted in conjunction with fixed overhead and variable overhead expenditure variances. Variable overhead variance can be an important performance measurement tool especially for the firms using marginal costing approach. Assume that the cost accounting staff of Company X has calculated that the company’s production staff works 10,000 hours per month. The company also incurs a cost of $100,000 per month as its variable overhead costs.

Therefore, these variances reflect the difference between the Standard Cost of overheads allowed for the actual output achieved and the actual overhead cost incurred. Practical applications of overhead variance analysis demonstrate its value across various industries. By regularly monitoring and analyzing overhead variances, businesses can control costs, improve efficiency, and make informed strategic decisions. Implementing effective variance analysis requires a combination of detailed budgeting, regular monitoring, and continuous improvement efforts.

A positive spending variance indicates that the actual costs were higher than the budgeted costs, suggesting overspending. Initially the actual variable overhead expense (electricity etc) would have been posted to the expense account with the usual entry of debit expense, credit accounts payable (not shown). Subsequently the journal above, allocates some of this expense (1,100) to production, this is represented by the credit entry to the expense account. Sometimes these flexible budget figures and overhead rates differ from the actual results, which produces a variance. This is the portion of volume variance that is due to the difference between the budgeted output efficiency and the actual efficiency achieved. Standards are used to facilitate better control and speed up the recording process.

Change in Production time can cause variable overheads to fluctuate significantly in the production process. Note that both approaches—the variable overhead efficiencyvariance calculation and the alternative calculation—yield the sameresult. This variance is unfavorable for Jerry’s Ice Cream becauseactual costs of $100,000 are higher than expected costs of$94,500. Understanding how your business stacks up against competitors can highlight areas for improvement and best practices.

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. For example, the number of labor hours taken to manufacture a certain amount of product may differ significantly from the standard or budgeted number of hours. Variable overhead efficiency variance is one of the two components of total variable overhead variance, the other being variable overhead spending variance. Figure 8.5 shows the connection between the variable overhead rate variance and variable overhead efficiency variance to total variable overhead cost variance.

Consider a consulting firm that budgets a standard variable overhead rate of $10 per consulting hour. However, the actual usage is 1,600 consulting hours, and the actual variable overhead costs are $16,800. Variable overhead variance refers to the difference between the actual variable overhead costs incurred and the standard or budgeted variable overhead costs for a given period.

Even though the answer is a negative number, the variance is favorable because we used less indirect materials than we budgeted. These tools can automate the calculation and reporting of variances, making it easier to identify and address discrepancies. Variable overhead is an indirect production expense that varies based on production.

With careful monitoring, the management may be able to find out idle work hours causing adverse variance to both labor rate and variable overhead rates. If an entity provide incentive to the operational managers and skilled labor for favorable variance it may motivate them to improve on the processes and low idle hours. Unavailability of raw materials, old machinery, and disruptions in the power supply are some of the uncontrollable factors that can still cause adverse variance in variable overhead rate analysis. The management should analyze in-depth for the production causing more machine-hours than expected. The production manager and skilled labor may also argue that standard machine-hours were set wrongly, as in our case if we set the standard machine hours at 0.30 then the same output measures will show a favorable overhead variance. The Standard setting is one of the main hurdles in variance analyses, as the market benchmarks for industry leaders are often unavailable or cannot be implemented for a smaller scale business.

The information given is largely based on historical and projected labor patterns. A large hospital analyzes its overhead variances to enhance financial performance and operational efficiency. By examining variable overhead variances, the hospital finds that overtime payments to variable overhead efficiency variance nursing staff are significantly higher than budgeted.

Because sometimes it’s not the hard work of the department which results in favorable variance, sometimes there are other factors also, which are not in control of the management. Thus, the production department does the same and provides an estimate of production costs that will be incurred in the following year. When variances are identified, conduct a thorough root cause analysis to understand the underlying factors.
