Variable Versus Absorption Costing

The method contrasts with absorption costing, in which the fixed manufacturing overhead is allocated to products produced. In accounting frameworks such as GAAP and IFRS, variable costing cannot be used in financial reporting. For example, assume a new company has fixed overhead of $12,000 and manufactures 10,000 units.

The concept of variable costing is a cost accounting concept that excludes the fixed manufacturing overhead costs from the calculation of production cost of goods. Thus all fixed manufacturing overhead costs are expensed in the period incurred regardless of the level of sales. The only difference between absorption costing and variable costing is in the treatment of fixed manufacturing overhead. Using absorption costing, fixed manufacturing overhead is reported as a product cost. Using variable costing, fixed manufacturing overhead is reported as a period cost. Figure 6.8 “Absorption Costing Versus Variable Costing” summarizes the similarities and differences between absorption costing and variable costing.

When can you use Variable Costing in Manufacturing?

Direct materials cost is $3 per unit, direct labor is $15 per unit, and the variable manufacturing overhead is $7 per unit. Under absorption costing, the amount of fixed overhead in each unit is $1.20 ($12,000/10,000 units); variable costing does not include any fixed overhead as part of the cost of the product. Figure 6.11 shows the cost to produce the 10,000 units using absorption and variable costing. In addition, the examples assumed that selling, general, and administrative costs were not impacted by specific actions. It is now time to consider aggregated financial data and take into account shifting amounts of SG&A.

• As its name suggests, only variable production costs are assigned to inventory and cost of goods sold.
• It is not necessary that all units produced within a given period will be sold in the same period as well.
• Although absorption costing is used for external reporting, managers often prefer to use an alternative costing approach for internal reporting purposes called variable costing.
• Managers should be aware that both absorption costing and variable costing are options when reviewing their company’s COGS cost accounting process.

The key point here is that variable costing information is useful, but it should not be the sole basis for decision making. The main reason behind prohibiting variable costing in preparation of financial statements for external use is because it fails to accord with the matching principle of accounting standards. Under variable costing, expenses are not reported in the same period with respect to the revenue generated from those expenses. On the other hand, the absorption costing approach requires reporting of expenses in the same period as the revenue generated from those expenses, which adheres to the matching principle. If the entire finished goods inventory is sold, the income is the same for both the absorption and variable cost methods. The difference is that the absorption cost method includes fixed overhead as part of the cost of goods sold, while the variable cost method includes it as an administrative cost, as shown in Figure 6.12.

Which method is more useful for internal decision making? Why? As a

Under absorption costing, fixed factory overhead is allocated to the finished goods inventory account and is expensed to cost of goods sold when the product is sold. For internal accounting purposes, both can also be used to value work in progress and finished inventory. The overall difference between absorption costing and variable costing concerns how each accounts for fixed manufacturing overhead costs. Using the absorption costing method on the income statement does not easily provide data for cost-volume-profit (CVP) computations.

The variable cost per unit is $22 (the total of direct material, direct labor, and variable overhead). The absorption cost per unit is the variable cost ($22) plus the per-unit cost of $7 ($49,000/7,000 units) for the fixed overhead, for a total of $29. Explain the main conceptual issue under variable costing and absorption costing regarding the timing for the release of fixed manufacturing overhead as expense. https://turbo-tax.org/what-is-net-working-capital-and-how-to-calculate/ A downward spiral of product discontinuation decisions can ultimately destroy a business that was otherwise successful. This illustration underscores why a good manager will not rely exclusively on absorption costing data. Variable costing techniques that help identify product contribution margins (as more fully described in the following paragraphs) are essential to guiding the decision process.

Do Private Companies Need to Follow GAAP & Absorption Costing?

This is why, companies are not allowed to use the variable costing method for the preparation of external reports. Despite the good benefits that companies can derive from using the absorption costing method, it has some disadvantages. The major dark sides of this costing method include the fact that it results in the increase of net income. Because this method accounts for fixed costs, the higher the goods produced at a time, the lesser the fixed costs that will be attributable to the production of the goods, which in turn causes the net income to increase. Hence, the fixed costs accounted for in this method is less favorable compared to variable costing. Another disadvantage of absorption costing is that cost volume profit (CVP) is difficult to analyze when it is being used.

Because costs like fixed manufacturing overhead are difficult to identify with a particular unit of output does not mean that they were not a cost of that output. However valid the claims are in support of absorption costing, the method does suffer from some deficiencies as it relates to enabling sound management decisions. Absorption costing information may not always provide the best signals about how to price a product, reach conclusions about discontinuing a product, and so forth. The difference between absorption costing and variable costing is in the treatment of fixed manufacturing overhead costs. It’s important to note that, like absorption costing, variable costing does not include non-manufacturing costs, such as selling, general, and administrative expenses, in the product cost.
