Answer:
Manufacturing overhead volume variance= $1,200 unfavorable
Step-by-step explanation:
First, we need to calculate the predetermined overhead rate:
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Fixed Predetermined manufacturing overhead rate= 1,200,000/240,000
Fixed Predetermined manufacturing overhead rate= $5 per machine hour
Now, to calculate the fixed manufacturing overhead volume variance, we need to use the following formula:
Manufacturing overhead volume variance = Actual Factory Overhead - Budgeted Allowance Based on Standard Hours
Manufacturing overhead volume variance= (101,200) - (5*20,000)
Manufacturing overhead volume variance= $1,200 unfavorable
