# How To Calculate Variable Overhead Efficiency Variance?

If a firm has performance based remuneration system, then it may result in a favorable variance. Becuase the remuneration will be paid based on outcome and not on the basis of actual hours worked. In this case, two elements are contributing to the favorable outcome. For example, the standard hours that the workers should have used to complete the 1,000 units is 100 hours. Variable overhead efficiency variance is the difference between actual hours worked at standard rate/price and standard hours allowed on standard rate/price.

Usually, the level of activity is either direct labor hours or direct labor cost, but it could be machine hours or units of production. 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. 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. On the other hand when actual hours exceed standard hours allowed, the variance is negative and unfavorable implying that production process was inefficient.

• The standard overhead rate is the total budgeted overhead of \$10,000 divided by the level of activity of 2,000 hours.
• Let us now put the values in the given formula to calculate VOEV.
• The standard hours are the total number of hours required by the company’s standard hours of the specific product to complete the production target during a particular period.
• For example, the company spends 5 more hours to produce an iPhone.

There is an inherent risk of arriving at a variance that does not represent an entity’s actual performance due to a margin of error. The error can directly result from an incorrect estimation or record of the standard number of labor hours. Therefore, the validity of the underlying standard, or lack thereof, must be accounted for in investigating the variable overhead efficiency variance. The Variable Overhead Efficiency Variance is a crucial component of the total overhead variance. And, it could prove an important tool for measuring performance, especially for the companies utilizing the marginal costing approach. For instance, management can use this variance to determine how efficiently the production team is using the resources, and if they are meeting the standard hour targets or not.

## What Is Variable Overhead Efficiency Variance

The results that arise from variable overhead efficiency variance is can be termed as a favorable or unfavorable variance. For example, the company spends 5 more hours to produce an iPhone. The management should analyze in-depth for the production causing more machine-hours than expected. 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. 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. While if the actual hours worked are higher than the budgeted hours estimated by management, we called it unfavorable variance. Hence, the application rate for VFOH is \$4 per labor hour (1,320/330). Last month, XYZ produced 9,600 units and employed 29,000 direct labor hours. Figure 8.5 shows the connection between the variable overhead rate variance and variable overhead efficiency variance to total variable overhead cost variance. In a standard cost system, overhead is applied to the goods based on a standard overhead rate. This is similar to the predetermined overhead rate used previously. The standard overhead rate is calculated by dividing budgeted overhead at a given level of production by the level of activity required for that particular level of production. Variable overhead variance can be an important performance measurement tool especially for the firms using marginal costing approach.

Being incurred are reduced by a factor of the decrease in hours worked. It does not necessarily mean that, in actual terms, the company incurred a lower overhead. It simply implies that an improvement was seen in the total allocation base used to apply overhead. If a firm buys a new machine that increases the production efficiency, then also favorable variance could occur. The production expense information is submitted by the production department of the enterprise. The estimated labor hours to meet output requirements are estimated by the staff responsible for industrial engineering and production scheduling.

And that’s why the efficiency graph goes higher and in the end, the result is a favorable one. Opportunity cost is the potential loss from a missed opportunity—the result of choosing one alternative and forgoing another.

If there is no threshold, then it could get difficult to determine whether or not the variance is significant.

Connie’s Candy used fewer direct labor hours and less variable overhead to produce 1,000 candy boxes . 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.

## Calculate Variable Overhead Efficiency Variance

The production staff takes into account efficiency and equipment capacity levels to come up with the projection. 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 reduction. Variable overhead efficiency variance refers to the difference between the true time it takes to manufacture a product and the time budgeted for it, as well as the impact of that difference. Any drop in the efficiency of machines due to continuous use may lead to unfavorable variance. Use of easy to handle raw materials leading to time savings can also result in a favorable variance. Standards are used to facilitate better control and speed up the recording process. To better manage accounts, standards may be established separately for variable and fixed factory overhead.

### What is the efficiency variance?

What Is Efficiency Variance? Efficiency variance is the difference between the theoretical amount of inputs required to produce a unit of output and the actual number of inputs used to produce the unit of output. The expected inputs to produce the unit of output are based on models or past experiences.

Required to manufacture a certain number of a product and the budgeted or standard number of hours. The difference can be significant and needs to be monitored and managed. A point to note is that a favorable VOEV does not necessarily mean that a firm incurs less actual overheads. If the outcome is favorable , this means the company was more efficient than what it had anticipated for variable overhead. If the outcome is unfavorable , this means the company was less efficient than what it had anticipated for variable overhead. Suppose Blue Tech produces a product and we have the data for variable and fixed overheads as below.

If the budget allowance based on actual hours worked is less than the budget allowance based on standard hours allowed, a favorable variable overhead efficiency variance occurs. Interpretation of the variable overhead rate variance is often difficult because the cost of one overhead item, such as indirect labor, could go up, but another overhead cost, such as indirect materials, could go down. Often, explanation of this variance will need clarification from the production supervisor. Another variable overhead variance to consider is the variable overhead efficiency variance. However, this result of \$400 of favorable variable overhead efficiency variance doesn’t mean that the company ABC’s total variable overhead variance is favorable.

• Any drop in the efficiency of machines due to continuous use may lead to unfavorable variance.
• Notice that fixed overhead remains constant at each of the production levels, but variable overhead changes based on unit output.
• This is a favorable variance because the actual hours are less than the standard hours.
• On the other hand, if the standard hours are less than the actual hours, the variance is unfavorable.
• If the outcome is favorable , this means the company was more efficient than what it had anticipated for variable overhead.

Cost of goods sold is defined as the direct costs attributable to the production of the goods sold in a company. Use of such raw material that is easy to handle and transform into finished product. Variable overhead is the indirect cost of operating a business, which fluctuates with manufacturing activity. Thus, it is possible that any error in the projection may result in a variance. So, it is important that when investigating the causes of variance, the management should review the validity of projections as well. Decline in the efficiency of manufacturing machines because of continuous use or wear and tear. Change in type of material, which allows machines and labor to work faster.

## Allocation Base And Application Rate

Connie’s Candy also wants to understand what overhead cost outcomes will be at 90% capacity and 110% capacity. The following information is the flexible budget Connie’s Candy prepared to show expected overhead at each capacity level. When variable overhead efficiency variance andfixed overhead efficiency variance are combined, they equal theoverhead efficiency variance. Using low quality or unavailability of certain raw material in time may result in unfavorable variance. This is a favorable variance because the actual hours are less than the standard hours.

### How do you calculate overhead cost per hour?

Most of the time, software companies calculate overhead costs by taking the total number of billable hours in all projects in a given period and divide their total overhead costs by that number. This is how they get the overhead rate per hour.

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. Likewise, the company can calculate variable overhead efficiency with the formula of the difference between standard and actual hours multiplying with the standard variable overhead rate. If the budget allowance based on actual hours worked is more than the budget allowance based on standard hours allowed, an unfavorable variable overhead efficiency variance occurs.

Like any other variance, this variance can also be favorable or adverse . A favorable VOEV is when the actual hours worked are less than standard hours. If the actual allocation base is greater than the standard, the company used more of it than expected. If the actual base is less than the standard base, the variance is favorable. Looking at Connie’s Candies, the following table shows the variable overhead rate at each of the production capacity levels. Change in Production time can cause variable overheads to fluctuate significantly in the production process. It also performs as an indicator of efficiency in the production process.

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 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. The standard overhead rate is the total budgeted overhead of \$10,000 divided by the level of activity of 2,000 hours. Notice that fixed overhead remains constant at each of the production levels, but variable overhead changes based on unit output.

Variable Overhead Efficiency Variance is a rucial component of total overhead variance, as well as OH expenditure variance. If the management makes any error in setting standards and budgets, then also there could be an adverse variance. If the budget allocation is more than usual due to wrong calcultion or estimation, then it may result in a favorable variance as well.

For example, the company ABC, which is a manufacturing company spends 480 direct labor hours during September. 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. Variable overhead efficiency is not just a calculation of standard and actual time rate; an entity should interpret with the total inputs utilization ratio to achieve higher outputs.

## Example Calculation Of Variable Overhead Efficiency Variance

This is an important management tool used to compare the budgeted hours allowed on the standard rate with actual hours worked on the standard rate. For example, the actual hours to produce an iPhone is 15 hours. However, one should interpret this variance in combination with fixed, as well as variable overhead expenditure variances. Moreover, one should also consider other factors, such as machine hours and labor hours, when analyzing this variance. The standard hours are the total number of hours required by the company’s standard hours of the specific product to complete the production target during a particular period. There will be a favorable variance if a firm replaces a less efficient machine with a more efficient one. This variance measures the production efficiency in converting inputs to outputs. Use of substandard or low quality raw material that is difficult to process or convert into finished product. Replacement of less efficient machine with a more efficient one which is capable of reducing the time required to manufacture a unit of product.

Variable overhead efficiency variance is a measure of the difference between the actual costs to manufacture a product and the costs that the business entity budgeted for it. Thus, it can arise from a difference in productive efficiency. Hours refers to the number of machine hours or labor hours incurred in the production of output during a period. Therefore, the company established a variable overhead rate of \$10 per hour. VOEV represents the production expense particulars that the production department submits. Moreover, it also represents projected labor hours to be worked. The projected hours are on the basis of estimates from the industrial engineering and production scheduling staff.
