Variable Costing—A Tool for Management Show Learning Objectives
Chapter Overview A. Overview of Variable and Absorption Costing. At least two methods can be used in manufacturing companies to value units of product for accounting purposes—absorption costing and variable costing. These methods differ only in how they treat fixed manufacturing overhead costs.
B. Comparison of Absorption and Variable Costing. When comparing absorption costing and variable costing income statements, a number of points should be noted:
C. Extended Comparison of Income Data. Exhibit 7-3 in the text presents a comparison of absorption costing and variable costing income statements over three years in which production is constant but sales vary. Exhibit 7-6 in the text also presents comparative income statements over three years but holds annual sales constant and varies annual production. From these Exhibits, several generalizations can be drawn. (All of these generalizations assume the LIFO inventory flow assumption is being used. The generalizations may not hold in some rare cases if a company uses an inventory flow assumption other than LIFO.)
D. The Matching Principle. Accountants and managers have been arguing for decades concerning the relative merits of absorption and variable costing. In practice, absorption costing is used far more than variable costing even for internal reports. The reasons for this are not entirely clear, although the perception that absorption costing is required for external reporting undoubtedly plays a key role. The argument for using absorption costing in external reports seems to be based on the matching principle.
E. Advantages of the Contribution Approach. There are a number of advantages to using variable costing (and the contribution approach) in internal reports and analysis.
F. Impact of JIT Inventory Methods. When companies use JIT methods for controlling their operations, the distortions of income that can occur under absorption costing largely (or completely) disappear.
Which accounting method variable or absorption would have produced the higher net income for?Answer and Explanation: Net operating income under absorption costing is higher than net income under variable costing due to the treatment of fixed overhead costs.
Why is net income higher absorption costing?When units produced are greater than units sold, i.e., units in inventory increase, absorption income is greater than variable costing income because absorption costing defers a portion of fixed manufacturing costs in finished goods inventory.
Which costing method is best absorption or variable?Because absorption costing includes fixed overhead costs in the cost of its products, it is unfavorable compared with variable costing when management is making internal incremental pricing decisions. This is because variable costing will only include the extra costs of producing the next incremental unit of a product.
Which costing method absorption or variable would show higher operating income and by what amount?Since all of the current fixed manufacturing overhead costs are expensed under variable costing, the net operating income reported under absorption costing will be greater than the net operating income reported under variable costing. 3.
