Q6. Using the information in Exhibit 4, calculate the cost of the five orders (A - E) under the “new” costing system. In order to calculate of the five orders under the new system, we need to calculate the cost of order processing and special components. Meanwhile, the cost of order processing is driven by the number of orders and special components cost is driven by the number of times processed. As Q5 shown, the cost of each order processed is $210.29 and the cost of per special processed is $60.00.

In the new costing system of SEMW, the support-related overhead includes in the cost of base motor and cost of special motor. We calculate the support cost of each order according to the order processing rate and special components rate. As illustrated in the Table 1 above, the cost of order increasing with more types of special components are needed. It is because not only higher cost of manufacturing those special components but also higher cost of spending in calling from special components from inventory or initiate special component production (e.g. design of special components). The increasing of total cost of each order mainly results from the increasing work loading on the production support department. Additionally, as Table 2 shown, more motors in an order would result in less support costs of special components for each motor. Only when base motor cost and special motor cost change, more motors are product in an order. What is more, the order processing cost and special components cost change when more types of special components are needed. Therefore, the more motors are produced in an order, the more profitable it will be. On the other hand, just 74% of the order accepted for production by EMW after the change in strategy was for less than five motors. Thus, the support cost is crucial for managers to decide whether accept the order or not.
