Cost accounting provides a company with measurement and allocation techniques to compute a good’s production cost. Variable costing is one method a company may use to complete this process. Under variable costing principles, direct materials, direct labor and variable manufacturing overhead represent the product’s cost. Fixed manufacturing overhead costs are a part of a company’s period expenses listed on the income statement. Variable costing is not allowable under generally accepted accounting principles as it violates proper accounting procedures for period expenses.
