An allocation base should be: Multiple choice question. a cost driver. a cost object. machine hours. direct labor hours.
The correct answer and explanation is:
Correct Answer: A. a cost driver
Explanation (300 words):
An allocation base is a measure used to assign overhead costs to products or services in a systematic and reasonable manner. The most accurate allocation base is one that reflects how the overhead costs are actually incurred. That’s why the best choice is “a cost driver.”
A cost driver is a factor that directly causes or relates to the incurrence of costs. For example, if a company’s overhead costs increase with more machine usage, machine hours become the cost driver. If overheads increase as more labor is used, direct labor hours become the cost driver. The idea is to link overhead costs with activities that generate those costs.
Let’s examine the other choices:
- Cost object: This refers to anything for which cost data is desired (such as a product, department, or customer). It is what you’re trying to assign the cost to, not the basis for the assignment. So, it is not an allocation base.
- Machine hours and Direct labor hours: While both of these can serve as allocation bases, they are not always the best option. If machine hours truly drive overhead costs, then they are appropriate. But if something else (like number of setups or inspections) better explains the cost behavior, then machine hours would not be ideal. Thus, they are examples of allocation bases — but not the definition.
Therefore, the most general and accurate answer is a cost driver, because it encompasses the principle that the allocation base should reflect the true cause of the cost being allocated. Choosing the correct cost driver ensures fairer product costing, better decision-making, and more accurate profitability analysis.
