CHAPTER 11 Costing and pricing in an entity 465
resource. For example, material requisitions record the product, service, business unit or activity that
has requested the material items, and payroll records record employee costs against specific business
units or tasks. The more costs that can be directly traced increases the accuracy of the costs for the cost
object. However, the cost of a tracking system can be prohibitive and entities will only commit resources
to trace costs if such costs are deemed important to the entity or the cost of tracking is minimal. A cost/
benefit test will be used by an entity to assess the costs against the benefits of a more detailed system
of tracking cost information. If the cost does not exceed the benefit, then the cost will be directly traced
to the cost object. If the cost is greater than the benefit, the cost will be assigned to an indirect cost
category, which is discussed below.
Direct cost Cost object
F I G U R E 11. 2 Relationship of direct cost to a single cost object
Indirect costs
Indirect costs (also referred to as overheads) are those costs that are used for the benefit of multiple
cost objects. An indirect cost has a relationship to many cost objects. Figure 11.3 shows the relation-
ship between an indirect cost and the many cost objects that consume the resource. These costs may be
directly traceable to an individual cost object, but such an exercise may not always pass the cost/benefit
test. For example, what would be involved in collecting information about the number of nails used in
the construction of a particular house if the builder is constructing 20 houses at the same time, or the
amount of glue used to laminate individual office desks? Clearly, the benefits of calculating these costs
would be outweighed by the cost of doing so. The question then arises as to how these indirect costs can
be allocated to the many cost objects that have made use of the resources? We will address this issue in
the following section.
The classification of a cost as either direct or indirect will depend on the specific cost object that has
been identified as the focus for the cost analysis, as well as on a cost/benefit assessment of tracing the
cost. The total cost of a cost object is:
Total cost of a cost object = direct costs + indirect costs
Cost object A
Cost object B
Cost object C
Indirect cost

object.
