The difference in how they treat fixed manufacturing overhead costs may lead to different net incomes reported under absorption costing and variable costing. When the number of units manufactured equals the number of units sold, net income under variable costing is equal to net income under absorption costing. When the number of units manufactured exceeds the number of units sold, net income under absorption costing will be greater than net income under variable costing. This is due to the fact that some of the goods manufactured during the period have not been sold. Fixed manufacturing overhead costs incurred during the period would not be expensed in entirety in the period in which they incurred. Some remain in ending inventories, which are shown in the statement of financial position.
