Final Answer:
The predetermined overhead rate for Dept. B is $2.12 per direct labor dollar, calculated by dividing the estimated manufacturing overhead by the estimated direct labor cost. This rate provides a basis for allocating overhead costs and is crucial for budgeting and cost control. Additionally, comparing the actual overhead rate, derived from the actual manufacturing overhead and direct labor cost, reveals a variance of $0.38.
Step-by-step explanation:
Calculate Predetermined Overhead Rate:
Predetermined Overhead Rate = Estimated Manufacturing Overhead / Estimated Direct Labor Cost
For Dept. B: $338,000 / $160,000 = $2.12 per direct labor dollar.
Calculate Actual Overhead Rate:
Actual Overhead Rate = Actual Manufacturing Overhead / Actual Direct Labor Cost
For Dept. B: $400,000 / $160,000 = $2.50 per direct labor dollar.
Analyze Overhead Variance:
Overhead Variance = Actual Overhead Rate - Predetermined Overhead Rate
Overhead Variance = $2.50 - $2.12 = $0.38.
So, the predetermined overhead rate per direct labor dollar for Dept. B is $2.12, and there is a positive overhead variance of $0.38.
