Systematic and rational allocation of expenses.For example, sales commission expenses can be directly traced to product sales, and a commission expense is recorded when a sale is made.

This method is used for many costs, and the expense is recognized when a direct relationship exists. Direct relationship between the expense and the associated revenue.In accounting, there are three ways to recognize expenses: You can envision the potential problems in creating an overhead allocation rate within these circumstances.īefore demonstrating the calculation of a predetermined overhead allocation rate, let’s review the basic principles of revenue recognition and expense. Estimating overhead costs is difficult because many costs fluctuate significantly from when the overhead allocation rate is established to when its actual application occurs during the production process. Therefore, in order to estimate manufacturing overhead, management must estimate the future purchase prices of dozens, or sometimes hundreds, of individual components, such as utilities, raw materials, contract labor, or diesel fuel. Manufacturing overhead costs include all manufacturing costs except for direct materials and direct labor. Establishing the overhead allocation rate first requires management to identify which expenses they consider manufacturing overhead and then to estimate the manufacturing overhead for the next year. For example, how do you know the cost of electricity and heat for manufacturing one job? And, if you did, is it fair to say products manufactured in January are more expensive than the same product manufactured in March because of heat expense? Fundamental Characteristics of the Overhead Determination EnvironmentĪdded to these issues is the nature of establishing an overhead rate, which is often completed months before being applied to specific jobs. Unfortunately, the nature of indirect material, indirect labor, and other overhead expenses makes it impossible to determine the exact amount of overhead for each specific job. Since production consists of overhead-indirect materials, indirect labor, and other overhead-we need a methodology for applying that overhead. Job order cost systems maintain the actual direct materials and direct labor for each individual job.
