4. Miniae Company uses departmental manufacturing overhead rates to apply overhead. Direct labor cost is used to apply manufacturing overhead in Department A and machine hours are used for Department B. Below are estimated costs for Miniae Company Direct Labor Cost Factory Overhead Direct Labor Hours Machine Hours Dept. A $66,000 $79,200 8,000 4,000 Dept. B $33,000 $60,000 9,000 | 15,000 ial costs are given below: Direct Labor Cost Factory Overhead Direct Labor Hours Machine Hours Dept. A $68,400 $78,000 8,100 4,200 Dept. B $32,000 $58,800 9,100 14,600 Calculate the predetermined overhead rate for Dept. A and for Dept. B. Predetermined Fact O/H Rate = Budget/Estimate/Predict Factory O/H Costs Budgeted/Estimated/Predicted Activity Dept. A Dept. B Calculate TOTAL Applied Overhead for both departments together. = X Applied Factory O/H Predetermined Factory O/H Rate Actual Activity Dept. A Dept. B Total Applied Overhead = -... Assume that the company uses a Plantwide rate based on Direct Labor Hours. Calculate the predetermined Plantwide rate. Predetermined Fact O/H Rate = Budget/Estimate/Predict Factory O/H Costs Budgeted/Estimated/Predicted Activity Calculate Applied Overhead using the Plantwide rate. Applied Factory O/H = Predetermined Factory O/H Rate X Actual Activity
