Answer :
Answer: a.fixed factory overhead volume variance.
Explanation:
Fixed overhead costs are the costs that are incurred by an organization that doesn't change even when the lre is a change in the volume of production activity. The fixed overhead costs are vital in order for the effective operation of the company.
When the standard fixed overhead rate is based on full capacity, the cost of available but unused productive capacity is indicated by the a.fixed factory overhead volume variance.
Variance is the data analysis tool that helps in measuring the gap between the actual and budgeted or the standard data. The standards are set based on past records and performances. There are various types of variances such as cost variance, efficiency variance, rate variance, volume variance, and many more.
The cost of available but unused productivity capacity is indicated by fixed factory overhead volume variance.
When the standard fixed overhead rate or can be said as the fixed overhead cost is constant and remains at full capacity irrespective of the changes in the volume of production activity.
In this case, the cost of productive capacity can be determined by using the fixed factory overhead volume variance. This is because it determines the difference between the fixed cost based upon the budgets and the production capacity.
