Definition
Fixed Overhead Capacity Variance, also known as Capacity Usage Variance or Idle Capacity Variance, is a concept used in standard costing systems to describe the variance that occurs when there is a difference between the actual hours worked and the budgeted hours available. This variance is calculated using the standard fixed overhead absorption rate per hour. The analysis can employ either machine hours or labor hours to assess how efficiently a company is utilizing its potential productive capacity.
Interpretation and Importance
Fixed Overhead Capacity Variance serves as a critical indicator for management, highlighting inefficiencies and the cost of unutilized resources. A favorable variance suggests that a company is maximizing its resources, whereas an unfavorable variance could signal idle machinery or manpower, indicating areas where operational adjustments are necessary to enhance productivity and cost efficiency.
Calculation
The variance is typically assessed with the formula: \[ \text{Fixed Overhead Capacity Variance} = (\text{Budgeted Hours} - \text{Actual Hours}) \times \text{Standard Overhead Rate per Hour} \]
Where:
- Budgeted Hours refer to the planned hours of operation or labor that should ideally be used under normal conditions.
- Actual Hours are the real hours utilized during the operation period.
- Standard Overhead Rate per Hour is the predetermined rate expected to cover the fixed overheads per unit of time.
Strategies to Manage Capacity Variance
To manage and reduce unfavorable fixed overhead capacity variance, businesses can:
- Improve Scheduling: Enhance the accuracy of production schedules to align more closely with demand forecasts.
- Maintenance and Upkeep: Regularly maintain equipment to minimize downtime and ensure maximum availability during operating hours.
- Workforce Training: Equip workers with multiple skills to ensure they can be redeployed on different tasks as needed, minimizing idle time.

- Standard Costing: A cost accounting method that assigns expected costs to each unit of production to help managers monitor performance.
- Budgeted Capacity: The expected or planned level of capacity output for a given period.
- Idle Capacity: Unused production capabilities, usually reflected as surplus resources or unutilized labor hours.
- Idle Capacity Ratio: A metric that compares the unused capacity to the total available capacity, emphasizing the proportion of resources not generating revenue.
