Using this formula of variable overhead efficiency variance in the calculation, the favorable variance or the unfavorable variance can also be determined with the result of the positive figure or the negative figure. If the result of the calculation is positive, the variance is favorable; on the other hand, if the result is negative, the variance is unfavorable. Okay, let’s talk about getting real control over those pesky variable overhead costs! Think of the Variable Overhead Efficiency Variance (VOEV) as your secret weapon. Because unlike some variances that feel like they’re influenced by the weather or the phase of the moon (supply chain issues anyone?), VOEV is often considered controllable. Tocalculate the standard rate of variable overhead per hour the budgeted totalvariable overhead expense is divided by the budgeted hours necessary forproduction.
Standard Hours (SH): Setting the Bar
Variable overhead is an indirect production expense that varies based on production. It includes variable overhead efficiency variance formula salaries and wages of factory supervisors and guards, utility bills, depreciation expenses, and others. Since the formula for this variance does not involve absorbed overhead, the basis of absorption of overhead is not a factor that influences the calculation of this variance. The only difference is the term SC(AO) being replaced by AbC in the formula using costs. Direct labor isn’t just about bodies in seats; it’s about efficiency, planning, and smart decision-making.
- It is entirely possible that an improperly-set standard number of labor hours can result in a variance that does not represent the actual performance of an entity.
- The standard variable OH rate per DLH is $0.80 (calculated previously), and the actual variable overhead for the month was $1,395 for 2,325 actual direct labor hours, giving an actual rate of $0.60.
- The company can calculate variable overhead efficiency variance with the formula of standard hours budgeted deducting the actual hours worked, then use the result to multiply with the standard variable overhead rate.
- However, the standard hours that are budgeted for the company to spend in the production process for September is 500 hours with the standard variable overhead rate of $20 per direct labor hour.
What is Variable Overhead Efficiency Variance? Definition, Formula, Explanation, And Analysis
It is entirely possible that an improperly-set standard number of labor hours can result in a variance that does not represent the actual performance of an entity. Consequently, investigation of the variable overhead efficiency variance should encompass a review of the validity of the underlying standard. On the other hand when actual hours exceed standard hours allowed, the variance is negative and unfavorable implying that production process was inefficient. Standard variable overhead rate is the rate that can be determined with the budgeted variable overhead cost dividing by the level of activity which in this case is either labor hours or machine hours.
If the variance is significant, the company must take appropriate measures to reduce such overheads to a minimum.

Budgets aren’t just dry numbers; they’re the foundation upon which we build our standards. When we’re talking about variable overhead, the budget helps us figure out what we expect to spend on things like electricity, machine maintenance, and indirect labor based on the production we plan to achieve. This expected spending becomes our benchmark, our “should be” level of variable overhead cost. Variable Overhead Efficiency Variance is the measure of impact on the standard variable overheads due to the difference between standard number of manufacturing hours and the actual hours worked during the period. So, the company ABC has a $400 favorable variable overhead efficiency variance in September.
In conclusion, budgeting sets the stage, standard costing provides the framework, and VOEV is your real-time indicator. It’s all about aligning your financial planning with your operational performance, ensuring that everyone’s rowing in the same direction. The variable overheads are based on the previous production practices, estimated working hours that will be required in the coming year, and the capacity level of the company. Change in Production time can cause variable overheads to fluctuate significantly in the production process. The Variable Overhead Efficiency Variance is the difference between the standard cost for actual output and the standard cost for actual input. Avariance in variable overheads may typically arise due to a sudden increase ininflation rate or maybe due to a change in supplier of indirect materials atthe eleventh hour.
Analysis
The variable overhead efficiency variance is used to assess how well a company has controlled its variable overhead costs. It is calculated by comparing the actual variable overhead costs incurred to the standard variable overhead costs that should have been incurred. An unfavorable variable overheadefficiency variance is when the standard hours required for production are lessthan the actual hours worked. The standard direct labor hours allowed (SH) in the above formula is calculated by multiplying standard direct labor hours per unit and actual units produced. A favorable variance occurs when the standard hours are more than the actual hours worked and signifies that the company incurred fewer variable overheads than expected. 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.
It means that instead of paying the labor a full rate for each hour saved, the company can give bonuses to the employees instead and reduce its manufacturing cost while increasing the revenue. This means you spent $1,000 more on variable overhead than you should have, because you took longer than expected. The importance of setting realistic and achievable standards cannot be overstated. The standard rate is adjusted per all price-increasing/decreasing factors (inflation rate, different suppliers, etc). Itmeans that the labor has worked inefficiently, the productivity has reduced andmore wages will be paid per hour while the revenue decreases as well due tolesser production. Ultimately, the decision of which structure to use is up to the management team of the company.
The variable overhead efficiency variance formula is calculated by multiplying the standard variable overhead rate by the difference between the actual hours worked and the standard hours allowed for the actual output produced. The variable overhead efficiency variance formula measures deviations between budgeted and actual manufacturing costs. This variance reflects the gap between standard variable overhead rates and actual overhead costs incurred per unit of production. Understanding this formula is crucial for assessing production efficiency, optimizing cost management, and identifying areas for improvement. By comparing actual costs to predetermined standards, companies can determine if their variable overhead usage is in line with expectations. However, the management should make sure to set the realistic standard or budget benchmarks taking into confidence the operations’ managers and the skilled labor.
This is due to the company ABC spends only 480 hours which is 20 hours less than the standard hours that are budgeted. By using standard cost against both the actual and expected quantity, we get the variance in dollars that is attributed to quantity only. Now, let’s get into standard costing, the system where VOEV feels right at home. A standard costing system uses these predetermined standards (like the variable overhead we just budgeted) to measure actual performance. Standard hours and actual hours can be labor hours or machine hours depending on which measurement is more suitable.
The standard variable OH rate per DLH is $0.80 (calculated previously), and the actual variable overhead for the month was $1,395 for 2,325 actual direct labor hours, giving an actual rate of $0.60. Inother words, it is the difference between standard hours and actual hoursworked at the standard variable overhead rate. Variable overheads account for an important and significant part of the total operating cost for any business, particularly in the manufacturing business. Variable overheads change with operating efficiency and contribute an integral part of total variable cost.
- An unfavorable variance indicates inefficiency in labor usage, while a favorable variance suggests efficient use of labor, impacting overall cost control within the company.
- Cost accountants using marginal costing method may be more interested in setting up lower standards I.e. higher hour rates to complete production to achieve favorable variances.
- Ultimately, the decision of which structure to use is up to the management team of the company.
Interpretation and Analysis
A favorable variance means that the actual hours worked were less than the budgeted hours, resulting in the application of the standard overhead rate across fewer hours, resulting in less expense being incurred. However, a favorable variance does not necessarily mean that a company has incurred less actual overhead, it simply means that there was an improvement in the allocation base that was used to apply overhead. A variable overhead efficiency variance is favorable when the actual hours worked by the labor are less than the standard hours required for the same production quantity. An adverse variable overhead efficiency variance suggests that more manufacturing hours were expended during the period than the standard hours required for the level of actual production. Favorable variable overhead efficiency variance indicates that fewer manufacturing hours were expended during the period than the standard hours required for the level of actual output. A favorable overhead (OH) rate variance indicated fewer hours taken to produce a product unit than expected or budgeted time.
Variable overhead efficiency variance is positive when standard hours allowed exceed actual hours. Therefore a positive value is favorable implying that production process was carried out efficiently with minimal loss of resources. The key factors that determine the variable overhead efficiency variance include the actual hours worked, the standard hours allowed for the actual output produced, and the standard variable overhead rate. The company can calculate variable overhead efficiency variance with the formula of standard hours budgeted deducting the actual hours worked, then use the result to multiply with the standard variable overhead rate. Variable overhead efficiency variance is the difference between the standard hours budgeted and the actual hours worked applying with the standard variable overhead rate.
Similarly, indirect labor salaries and wages, including factory supervisors and guards, are estimated. Such an estimate is then incorporated into the total variable overhead expense. Variable overheads are indirect production costs incurred by the company as the output varies. Since the calculation of variable overhead efficiency variance is not influenced by the method of absorption used, the value of the variance would be the same in all cases. Actual hours are the hours that the company’s workforce actually spends during the period or actually spends to complete a certain number of units of production.
The Marginal costing approach takes into account variable overhead costs that can directly be linked with variable overhead efficiency. Production managers prepare standard or budgeted Overhead (OH) efficiency rates using past data; however, many other factors may cause favorable or unfavorable variances. In the marginal costing approach, a fraction of change in variable overheads can result in a change in contribution margins. Cost accountants using marginal costing method may be more interested in setting up lower standards I.e. higher hour rates to complete production to achieve favorable variances. A variable overhead efficiency variance is one of the two contents of a total variable overhead variance. It is the difference between the actual hours worked and the standard hours required for budgeted production at the standard rate.
