variable overhead efficiency variance formula

By using standard cost against both the actual and expected quantity, we get the variance in dollars that is attributed to quantity only. 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 results that arise from variable overhead efficiency variance is can be termed as a favorable or unfavorable variance.

  • The other variance computes whether or not actual production was above or below the expected production level.
  • Variable overhead efficiency variance is positive when standard hours allowed exceed actual hours.
  • Costs such as direct material and direct labor, on the other hand, vary directly with each unit of output.
  • The variable overhead efficiency variance is a combination of production expense data submitted by the production line and forecasted labor hours to be worked.

Understanding and managing variable overhead efficiency and spending variances is crucial for manufacturers seeking to improve their bottom line and remain competitive in today’s global market. The variance in variable overhead efficiency is significant to manufacturers as it measures the efficiency and effectiveness of their production processes. One key aspect of cost management is tracking and analyzing variable overhead efficiency variance (VOEV). For example, the labor hours required to create a certain amount of a product may deviate somewhat from the anticipated or budgeted number of hours.

Example of the Variable Overhead Efficiency Variance

The difference between actual and budgeted hours worked is the variable overhead efficiency variance, which is subsequently applied to the standard variable overhead rate per hour. When a favorable variance is achieved, it implies that the actual hours worked during the given period were less than the budgeted hours. It results in applying the standard overhead rate across fewer hours, which means that the total expenses 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.

This variance arises due to the difference in the number of working days when the actual number of working days is greater than standard working days. At Finance Strategists, we partner with financial experts to ensure the accuracy of our financial content. This variance can be caused by several factors, similar to a deficit of experienced labor, insufficient training or supervision, or poor employee morale.

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. Variable overhead spending variance is favorable if the actual costs of indirect materials — for example, paint and consumables such as oil and grease—are lower than the standard or budgeted variable overheads. The standard variable overhead rate is typically expressed in terms of the number of machine hours or labor hours depending on whether the production process is predominantly carried out manually or by automation.

By contrast, efficiency variance measures efficiency in the use of the factory (e.g., machine hours employed in costing overheads to the products). When real hours exceed the number of hours allowed by the standard, the variance is negative and unfavorable, suggesting that the manufacturing process was inefficient. By examining the factors contributing to favorable or unfavorable variance, companies can make informed decisions to boost efficiency, reduce costs, and maximize profits.

Overhead Variances FAQs

While if the actual hours worked are higher than the budgeted hours estimated by management, we called it unfavorable variance. An overhead cost variance is the difference between how much overhead was applied to the production process and how much actual overhead costs were incurred during the period. For service-oriented businesses, where labor and other inputs are higher than variable overhead costs, VOEV may not provide meaningful insights into the company’s efficiency. VOEV only considers variable overhead costs and does not account for fixed overhead costs. Before we go on to explore the variances related to fixed indirect costs (fixed manufacturing overhead), check your understanding of the variable overhead efficiency variance. Connie’s Candy used fewer direct labor hours and less variable overhead to produce 1,000 candy boxes (units).

Analyzing the variance and identifying areas for improvement can help you save funds while making your business more maintainable. Consequently, associating the root causes of both types of variance can mean the difference between success and failure in one’s competitive business. For instance, a business enterprise can also put money into a new system, provide employee training, or enhance supply chain control to reduce inefficiencies and enhance productivity. It can be performed by reading the production statistics, identifying bottlenecks inside the method, and enforcing corrective actions. While the company can control and improve internal factors, external factors are often beyond the manufacturer’s control.
