Which of the following is a disadvantage of single-rate method?
Calculating an accurate manufacturing cost for each product is a vital piece of information for a company’s decision-making. For example, knowing the cost to produce a unit of product affects not only how a business budgets to manufacture that product, but it is often the starting point in determining the sales price. Show
An important component in determining the total production costs of a product or job is the proper allocation of overhead. For some companies, the often less-complicated traditional method does an excellent job of allocating overhead. However, for many products, the allocation of overhead is a more complex issue, and an activity-based costing (ABC) system is more appropriate. Another factor to consider in determining which of the two major overhead allocation methods to use is the cost associated with collecting and analyzing information. When making their decision regarding which method to use, the company must consider these costs, both in time and money. Table 9.4 compares overhead in the two systems. In many cases, the ABC method is more expensive in terms of time and other costs. The difference between the traditional method (using one cost driver) and the ABC method (using multiple cost drivers) is more complex than simply the number of cost drivers. When direct labor is a large portion of the product cost, the overhead costs tend to be consistently driven by one cost driver, which is typically direct labor or machine hours; the traditional method appropriately allocates those costs. When technology is a large portion of the product cost, the overhead costs tend to be driven by multiple drivers, so using multiple cost drivers in the ABC method allows for a more precise allocation of overhead.

As shown with Musicality’s products, not only are there different costs for each product when comparing traditional allocation with an activity-based costing, but ABC showed that the Solo product creates a loss for the company. Activity-based costing is a more accurate method, because it assigns overhead based on the activities that drive the overhead costs. It can be concluded, then, that the cost and subsequent gross loss for each unit’s sales provide a more accurate picture than the overall cost and gross profit under the traditional method. Table 9.4 compares the cost per unit using the different cost systems and shows how different the costs can be depending on the method used. Advantages and Disadvantages of the Traditional Method of Calculating OverheadThe traditional allocation system assigns manufacturing overhead based on a single cost driver, such as direct labor hours, direct labor dollars, or machine hours, and is optimal when there is a relationship between the activity base and overhead. This most often occurs when direct labor is a large part of the product cost. The theory supporting the single cost driver is that the cost driver selected increases as overhead increases, and further analysis is more costly than it is valuable. Each method has its advantages and disadvantages. These are advantages of the traditional method:
Disadvantages of the traditional method include:
While ABC systems more accurately allocate the costs based on the various resources used to make the product, they cost more to use and, therefore, are not always the best method. Management needs to consider each system and how it will work within its own organization. Some advantages of activity-based costing include:
There are disadvantages to using ABC costing that management needs to consider when determining which method to use. Those disadvantages include:
The advantages and disadvantages of both methods are as previously listed, but what is the practical impact on the product cost? There are several items to consider at the product costs level:
What are the advantages of using the single rate method?A) It is the most widely used method in practice. B) It is less costly to implement. C) It avoids the expensive analysis for categorizing costs as either fixed or variable. D) It allocates fixed cost as per the budgeted usage that helps in short and long-run planning.
What is single rate method?The main difference between the single rate and dual rate method is that the single rate method allocates the rate per unit of cost allocation for both variable and fixed cost.
Which one of the following is a disadvantage of the dual rate method of allocating support department costs?Which of the following is a disadvantage of a dual-rate method? A) It allocates fixed costs on the basis of budgeted long-run usage, which may tempt some managers to underestimate their planned usage.
Which of the following describes the complete reciprocated cost?Definition: For the reciprocal method of cost accounting, a complete reciprocated cost is the budgeted amount for a service department plus any allocations from other service departments.
