The concept of Variable Overhead Expenditure Variance (VOEV) emerged alongside the development of standard costing systems in the early 20th century. Standard costing became popular during the industrial revolution, offering businesses a way to control costs and manage budgets effectively.
Definition and Explanation
Variable Overhead Expenditure Variance is a measure used in standard costing to identify the difference between the budgeted variable overhead costs and the actual variable overhead costs incurred. This variance helps businesses to assess the efficiency and effectiveness of their variable overhead cost management.
Key Elements
Types/Categories
- Favorable Variance (F): Occurs when actual variable overhead costs are less than budgeted costs.
- Unfavorable Variance (U): Occurs when actual variable overhead costs are more than budgeted costs.
Key Events
- Budget Preparation: Setting standard costs for variable overheads.
- Actual Cost Incurrence: Recording the actual variable overhead costs.
- Variance Analysis: Comparing budgeted and actual costs to calculate the variance.
Detailed Explanation
Formula
The formula to calculate VOEV is:
Example Calculation
Given Data:
- Budgeted variable overhead cost per unit: $5
- Actual variable overhead cost per unit: $6
- Units produced: 1,000

Importance
VOEV is crucial for:
- Identifying cost control effectiveness.
- Detecting inefficiencies in resource usage.
- Enhancing budgetary discipline and cost management.
Applicability
- Manufacturing Companies: For analyzing production cost variances.
- Service Industries: For managing variable costs like utilities.
- Project Management: For monitoring project overhead costs.
Considerations
- Accuracy in budgeting and recording costs.
- Periodic review to ensure reliable variance analysis.
- Effective communication of variance findings to stakeholders.
Related Terms
- Fixed Overhead Expenditure Variance: Difference between budgeted and actual fixed overhead costs.
- Standard Costing: Method of cost accounting that compares standard costs to actual costs.
- Budget Variance: Overall difference between budgeted and actual performance.
Comparisons
- VOEV vs. FOEV: VOEV deals with variable costs, while FOEV deals with fixed costs.
- VOEV vs. Sales Variance: VOEV analyzes cost variances, whereas sales variance analyzes revenue variances.
Interesting Facts
- Standard costing and variance analysis helped companies manage during the World Wars by controlling expenses.
- Businesses can use VOEV insights to negotiate better rates with suppliers.

- “Cost creep”: Gradual increases in budgeted costs.
FAQs
Q: How often should VOEV be calculated? A: Ideally, VOEV should be calculated monthly or quarterly to provide timely insights.
Q: What causes an unfavorable VOEV? A: Factors may include inefficient use of resources, increased utility rates, or unexpected operational changes.
Q: How can companies reduce unfavorable VOEV? A: By improving process efficiency, renegotiating supplier contracts, and implementing stricter budget controls.
