Variable Overhead Efficiency Variance: Understanding, Calculating, and Navigating Examples
BP
Summary:
Variable Overhead Efficiency Variance is a crucial metric that measures the difference between actual and budgeted labor hours in manufacturing processes. This article delves into its definition, formula, and implications, using practical examples to illustrate its impact on business operations.
Understanding variable overhead efficiency variance
Variable Overhead Efficiency Variance plays a pivotal role in assessing the productivity of labor in a manufacturing environment. It is the difference between the actual labor hours (ALH) and the budgeted labor hours (BLH), multiplied by the hourly rate for standard variable overhead.
In numerical terms, the formula is expressed as follows:
VOEV = (ALH – BLH) × Hourly Rate
Here, if the actual labor hours are less than the budgeted hours, the variance is considered favorable; otherwise, it is unfavorable.
The components of the formula
Breaking down the formula, the hourly rate incorporates various indirect labor costs, including those for shop foremen and security. This comprehensive approach ensures that the calculation considers all relevant factors influencing labor efficiency.
Example of variable overhead efficiency variance
To better understand the practical implications of Variable Overhead Efficiency Variance, let’s consider a hypothetical example:
Consider a widget-manufacturing plant with a standard variable overhead rate of $20 per hour. The standard time to manufacture 1,000 widgets is budgeted at 2,000 hours. However, the actual time taken is 2,200 hours.
In this scenario, the unfavorable Variable Overhead Efficiency Variance can be calculated as:
(2,200 – 2,000) × $20 = $4,000
The unfavorable variance indicates that the company exceeded the budgeted time to produce the widgets, incurring additional costs.
Conversely, if the actual time taken was 1,900 hours, the variance would be favorable:
(1,900 – 2,000) × $20 = -$2,000
This time, the negative sign denotes a favorable variance, indicating that the company completed the manufacturing process more efficiently than budgeted.
