Compute the predetermined overhead allocation rates using machine hours as the allocation base for the Assembly Department and direct labor hours for the Packaging Department. Begin by selecting the formula to calculate the predetermined overhead (OH) allocation rate. Then enter the amounts to compute the allocation rate for each department. (Abbreviation used: Qty = quantity. Enter the allocation rates to the nearest cent.) Predetermined OH Estimated overhead costs Estimated qty of the allocation base Assembly Packaging $ 460,000 164,000 287,500 allocation rate 1.60 410,000 0.40 How much overhead is allocated to the basic model? To the professional model? Begin by selecting the formula to allocate overhead (OH) costs. (Abbreviation used: Qty = quantity.) Predetermined OH allocation rate Actual qty of the allocation base used = Allocated mfg. overhead costs Compute the total overhead allocated to the basic model, and then compute the total overhead allocated to the professional model.
