Variable Overhead Efficiency Variance

What is Variable Overhead Efficiency Variance?

In the context of standard costing, the variable overhead efficiency variance is an accounting metric that quantifies the difference between the actual labor hours worked and the standard hours expected for the actual output achieved. This variance is then multiplied by the standard variable overhead absorption rate per hour.

It’s a key performance indicator that helps businesses understand how efficient they were in using their labor to support variable overheads during production.

Formula:

\[ \text{Variable Overhead Efficiency Variance} = (\text{Actual Hours Worked} - \text{Standard Hours Allowed}) \times \text{Standard Variable Overhead Rate} \]

Examples

Example 1:
- Actual Hours Worked: 1,000 hours
- Standard Hours Allowed: 900 hours
- Standard Variable Overhead Rate: $5 per hour
\[ \text{Variable Overhead Efficiency Variance} = (1,000 - 900) \times $5 = $500 \text{ Unfavorable} \]
Example 2:
- Actual Hours Worked: 800 hours
- Standard Hours Allowed: 850 hours
- Standard Variable Overhead Rate: $7 per hour
\[ \text{Variable Overhead Efficiency Variance} = (800 - 850) \times $7 = -$350 \text{ Favorable} \]

Frequently Asked Questions

What causes a variable overhead efficiency variance?
- A variance can be caused by differences in actual labor hours worked versus the expected (standard) hours needed to produce a specific quantity. Factors include inefficiencies, changes in processes, labor issues, or machine downtime.
What does a favorable variance indicate?
- A favorable variance indicates that the actual labor hours worked were less than the standard hours allowed, suggesting greater efficiency and reduced variable overhead costs.
What does an unfavorable variance signify?
- An unfavorable variance suggests that more hours were worked than what was allowed under standard costing, indicating inefficiencies that lead to higher costs.
How can a company manage overhead efficiency variances?
- Companies can manage these variances through better workforce training, optimizing production processes, or upgrading equipment to reduce downtime and increase efficiency.

Standard Costing: A system of cost accounting which uses standard costs to control and manage costs.
Overhead Efficiency Variance: A broader term that includes both fixed and variable overheads, indicating the efficiency in the use of various overhead resources.
Standard Time: The time allowed as per standards set for producing a certain quantity of goods.
Variable Overhead Rate: The expected cost of variable overheads per labor hour.
