Variables
Description
What is this formula?
Overhead Volume Variance (OVV) measures the effect of operating at a production volume different from the volume used when budgeting fixed manufacturing overhead.
It indicates whether fixed overhead costs were over-absorbed or under-absorbed due to differences between actual production activity and planned capacity.
When to use it
Use this formula in standard costing systems to evaluate capacity utilization, production planning accuracy, and the allocation of fixed manufacturing overhead costs.
Example
A factory has the following data:
Standard Hours Allowed = 12,000 h
Budgeted Hours = 10,000 h
Fixed Overhead Rate = $8/h
Formula:
OVV=(SH-BH)FOH
Substitution:
OVV=(12,000-10,000)×8
OVV=16,000
Result:
Overhead Volume Variance = $16,000 favorable
Applications
Standard costing systems
Manufacturing accounting
Capacity utilization analysis
Budget control
Factory performance evaluation
Note
Overhead Volume Variance is an accounting allocation measure rather than a physical law. The interpretation depends on the costing system used and the method for allocating fixed overhead. Some organizations report favorable variances as positive values, while others use the opposite sign convention.
