Direct material cost is the cost of the raw materials and components used to create a product. The materials must be easily identifiable with the resulting product (otherwise they are considered to be joint costs).The direct material cost is one of the few variable costs involved in the production process; as such, it is used in the derivation of throughput from production processes.Throughput is sales minus all totally variable expenses. Examples of direct materials are: 1  The timber used to construct a house.hen assign a standard cost to each item, based on recent prices paid for them (including freight and sales taxes), and add a reasonable allowance for scrap and spoilage. The total is the direct material cost of the product.
