Product and Period Costs

Costs which are needed to produce a product are referred to as product costs, all other costs are known as period costs.

Product Costs

Product costs are needed to produce the product and are sometimes referred to as inventory costs as they are included in the cost of inventory of the business until the products are sold.

Product costs can be separated into direct and indirect costs.

Direct Product Cost

Direct product costs consist of those which can be easily identified and traced back to the product, they include direct materials and direct labor.

Direct Materials

Direct material cost is the cost of all the identifiable materials used in the production of a product. It must be possible to easily identify, track or count the materials to a particular unit of production. So for example, if a business manufactures bicycles, then the metal used to produce the frame would be referred to as a direct material product cost.

Direct Labor

Direct labor cost is the gross wage cost of all the labor associated with a particular job. The labor included must relate to those employees who are directly working on the item being produced. In our bicycle manufacturer example, the labor used to produce the frame would be a direct labor product cost.

Indirect Product Cost

Indirect product costs are those needed to produce the product, but which cannot be easily identified or tracked to a particular unit of production. Indirect product costs might be materials, labor or other.

In the case of the bicycle manufacturer for example, oil used in the production process is not easily identified with a particular unit of production but is still a product cost, and is therefore an indirect material product cost, which is allocated across all units of production on a predefined basis. Like wise, the factory supervisor is needed to produce the product and is therefore a product cost but cannot be identified with a particular unit of production and is therefore an indirect labor product cost.

In a manufacturing business indirect products costs are often referred to as manufacturing overhead, and are allocated to units of production on an agreed basis such as machine hours or labor hours used in the production of the product.

Treatment of Product and Period Costs in Financial Statements

It is important to separate costs into product and period costs as their treatment in the financial statements differs.

Product Costs

Product costs become part of the inventory cost of a business and are held on the balance sheet until the product is sold, at which point they are transferred to the income statement as part of the cost of goods sold expense.

Period Costs

Period costs are treated as an expense in the income statement in the period in which they are incurred.
