The timing difference affects the balance sheet as well because inventory on the balance sheet includes a portion of the fixed manufacturing overhead relating to the units unsold under absorption costing, while no fixed manufacturing overhead is reported as part of inventory under variable costing. Contribution margin ratio The c ontribution margin ratio is calculated by dividing the contribution margin per unit by the selling price per unit.

While managers --the internal users--need more information than what is reported externally. The process involved can be explained by referring to income statements prepared above. Key point: Net operating income is greater under absorption costing when the number of units produced exceeds the number of units sold.
Variable costing can make it more difficult to determine ideal pricing for its goods and services since it does not directly consider all of the costs the company has to cover to be profitable. 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. It is expressed as a percentage with two decimal places displayed: xx.

Ending inventory under variable costing As show in the Finished Goods inventory T-account for the year, ending inventory consists of 30 door knobs. The choice between variable and absorption costing is based on the needs of the respective users. When the number of units sold differs from the number produced during the period, a timing difference occurs due to when the fixed manufacturing overhead costs are expensed. Absorption costing is also the method that a company is required to use for calculating and filing its taxes.

For internal accounting purposes, managers use variable costing which treats only materials, labor and variable manufacturing overhead as product costs. One of the big advantages of absorption costing is that it is the method required for a company to be in compliance with. When the units are later taken out of inventory and sold, the deferred fixed costs flow through to the income statement as part of cost of goods sold.
Solution Income statement using variable costing The number of units used on the income statement for revenue and variable costs is based on the units sold for the year. So total manufacturing overhead cost is charged in the period regardless their sales volume. Instead, these costs are deferred to a future period and are carried on the balance sheet as part of the inventory account. A formal reconciliation of variable costing income to absorption costing income begins with variable costing net operating income determined on the variable costing income statement. We know that if inventory increase during the year then the net operating income is increased under absorption costing than that of viable costing net operating income statement.
Because only variable manufacturing costs are considered product costs, the entire fixed manufacturing cost appears on the income statement as a period cost. Ethical Issues Managers are able to manipulate operating income with no effect to sales revenue by producing more or fewer units of product.
