Capacity Usage Variance

Definition

Capacity Usage Variance (CUV) is a metric used in management accounting to analyze the efficiency of capacity utilization in relation to fixed overhead costs. It represents the deviation between the actual number of hours worked and the budgeted hours planned, multiplied by the standard overhead rate. This variance helps in understanding whether a company has overutilized or underutilized its capacity.

Formula:

\[ \text{Capacity Usage Variance} = (\text{Actual Hours Worked} - \text{Budgeted Hours}) \times \text{Standard Overhead Rate} \]

A positive variance indicates overutilization, while a negative variance signifies underutilization of capacity.

Examples

Example 1: Manufacturing Company
- Budgeted Hours: 1,000 hours
- Actual Hours Worked: 1,200 hours
- Standard Overhead Rate: $50/hour
Calculation:
- CUV = (1,200 - 1,000) × $50 = 200 × $50 = $10,000 (Positive Variance)
The positive variance indicates that the company worked 200 hours more than budgeted, resulting in $10,000 additional overhead absorption.
Example 2: Service Firm
- Budgeted Hours: 500 hours
- Actual Hours Worked: 450 hours
- Standard Overhead Rate: $100/hour
Calculation:
- CUV = (450 - 500) × $100 = -50 × $100 = -$5,000 (Negative Variance)
The negative variance indicates that the firm worked 50 hours less than budgeted, resulting in $5,000 under absorption of overheads.

Frequently Asked Questions (FAQs)

Q1: What is the significance of Capacity Usage Variance?

A: Capacity Usage Variance is significant as it helps businesses understand how effectively they are utilizing their production capacity and managing fixed overhead costs.

Q2: How can businesses reduce negative capacity usage variance?

A: To reduce negative capacity usage variance, businesses can improve demand forecasting, adjust workforce scheduling, and enhance operational efficiency.

Q3: Is a positive capacity usage variance always beneficial?

A: Not necessarily. While a positive variance indicates higher utilization, it may also signify overworking resources, which can lead to operational inefficiencies and increased maintenance costs.

Q4: How does Capacity Usage Variance relate to Fixed Overhead Capacity Variance?

A: Both variances measure the difference between actual and budgeted hours in relation to fixed overheads but from different perspectives. Fixed Overhead Capacity Variance focuses more on the budgeted capacity versus actual usage, whereas CUV delves into the rate impact of this difference.

Fixed Overhead Capacity Variance:
- Represents the difference between the budgeted fixed overheads for actual production hours and the standard hours allowed for actual output.
Efficiency Variance:
- Measures the difference between actual input required at a standard rate versus the actual amount consumed. It is often related to labor or material efficiency.
Overhead Absorption Rate (OAR):
- The rate at which overhead costs are applied to products, typically calculated based on budgeted overhead costs divided by budgeted activity levels.
Standard Costing:
- An accounting method that uses standard costs to control and manage production costs. It helps in identifying variances and taking corrective actions.
