Knowing about cost allocation will help you understand the various types of costs and how they're allocated during the production process. In these lessons, we'll discuss several types of costs, how they're checked for variances, and why management needs this information. We'll also explore activity analysis and estimating costs, relevant costs and benefits, costs systems, and make-or-buy decisions. Cost allocation is a relatively simple concept, but it can also be a highly detailed and difficult task. Cost allocation involves assigning cost to cost objects, such as a customer, a product, or even a department or a divisional section of the company in a way that accurately represents a proper share of the costs. There are direct costs and indirect costs. Direct costs can be directly attributed or traced to a cost object. In a manufacturing company, this would include all costs that are directly attributed to the products manufacturer. For example, labor is a direct cost. Laborers clock in and out during their shift. And the company keeps track of the number of units produced during the period. Raw materials are another example of direct costs. When raw materials are purchased, they can be assigned a purchase order number which links the raw materials to the cost object. If the raw materials are purchased to produce a large quantity of products, then as the raw materials are used in the production process, their costs are assigned to each individual product. Indirect costs can be allocated to the production of the product, but not in an accurate or cost effective way. For example, a manufacturing company will have plant managers, shift managers and administrative staff who are involved in the manufacturing process of all of the products. But their level of input per product can't be accurately allocated. These members don't punch a time clock or track the number of hours that they spend thinking, planning or directing plant operations. Indirect costs have to be reasonably allocated per product to accurately reflect the costs associated with production. Many organizations employ cost assignment practices that help trace the indirect costs and allocate them in a cost-effective manner.
