When is variable costing used

Financial Analysis How to Value a Company. Absorption Costing vs. Variable Costing: An Overview Absorption costing includes all the costs associated with the manufacturing of a product, while variable costing only includes the variable costs directly incurred in production but not any of the fixed costs. Key Takeaways Absorption costing includes all of the direct costs associated with manufacturing a product, while variable costing can exclude some direct fixed costs.

Absorption costing, also known as full costing, entails allocating fixed overhead costs across all units produced for the period, resulting in a per-unit cost.

Variable costing includes all of the variable direct costs in COGS but excludes direct, fixed overhead costs. Article Sources.

Full Costing Definition Full costing is a managerial accounting method that describes when all fixed and variable costs are used to compute the total cost per unit.

Hence, the fixed manufacturing overheads are allocated against sales during the period in which they are incurred. Also, variable costs comprise of direct materials, direct labor, and variable manufacturing overheads.

Hence, with both methods, he arrives at the same conclusion, but the difference is in the way each method allocates the fixed manufacturing overheads on the income statement. The break-even point occurs when fixed costs equal the gross margin , resulting in no profits or loss. A company that seeks to increase its profit by decreasing variable costs may need to cut down on fluctuating costs for raw materials, direct labor, and advertising. However, the cost cut should not affect product or service quality as this would have an adverse effect on sales.

By reducing its variable costs, a business increases its gross profit margin or contribution margin. The contribution margin allows management to determine how much revenue and profit can be earned from each unit of product sold.

The contribution margin is calculated as:. Profits increase when the contribution margin increases. Common examples of variable costs include costs of goods sold COGS , raw materials and inputs to production, packaging, wages, and commissions, and certain utilities for example, electricity or gas that increases with production capacity.

Variable costs are directly related to the cost of production of goods or services, while fixed costs do not vary with the level of production. Fluctuations in sales and production levels can affect variable costs if factors such as sales commissions are included in per-unit production costs.

Meanwhile, fixed costs must still be paid even if production slows down significantly. If companies ramp up production to meet demand, their variable costs will increase as well. If these costs increase at a rate that exceeds the profits generated from new units produced, it may not make sense to expand.

A company in such a case will need to evaluate why it cannot achieve economies of scale. In economies of scale, variable costs as a percentage of overall cost per unit decrease as the scale of production ramps up. Marginal cost refers to how much it costs to produce one additional unit. The marginal cost will take into account the total cost of production, including both fixed and variable costs. Since fixed costs are static, however, the weight of fixed costs will decline as production scales up.

Finally, at the point of sale, whenever it happens, these deferred production costs, such as fixed overhead, become part of the costs of goods sold and flow through to the income statement in the period of the sale.

This treatment is based on the expense recognition principle , which is one of the cornerstones of accrual accounting and is why the absorption method follows GAAP.

The principle states that expenses should be recognized in the period in which revenues are incurred. Including fixed overhead as a cost of the product ensures the fixed overhead is expensed as part of cost of goods sold when the sale is reported. For example, assume a new company has fixed overhead of? Direct materials cost is? Under absorption costing, the amount of fixed overhead in each unit is?

Figure shows the cost to produce the 10, units using absorption and variable costing. Assume each unit is sold for? 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. When the entire inventory is sold, the total fixed cost is expensed as the cost of goods sold under the absorption method or it is expensed as an administrative cost under the variable method; net income is the same under both methods.

Now assume that 8, units are sold and 2, are still in finished goods inventory at the end of the year. The cost of the fixed overhead expensed on the income statement as cost of goods sold is? The amount of the fixed overhead paid by the company is not totally expensed, because the number of units in ending inventory has increased. Eventually, the fixed overhead cost will be expensed when the inventory is sold in the next period.

Figure shows the cost to produce the 8, units of inventory that became cost of goods sold and the 2, units that remain in ending inventory. If the 8, units are sold for? Under absorption costing, the 2, units in ending inventory include the? That cost will be expensed when the inventory is sold and accounts for the difference in net income under absorption and variable costing, as shown in Figure.

Under variable costing, the fixed overhead is not considered a product cost and would not be assigned to ending inventory. The fixed overhead would have been expensed on the income statement as a period cost. Because absorption costing defers costs, the ending inventory figure differs from that calculated using the variable costing method. As shown in Figure , the inventory figure under absorption costing considers both variable and fixed manufacturing costs, whereas under variable costing, it only includes the variable manufacturing costs.

Using the absorption costing method on the income statement does not easily provide data for cost-volume-profit CVP computations.

In the previous example, the fixed overhead cost per unit is? If the company estimated 12, units, the fixed overhead cost per unit would decrease to? This calculation is possible, but it must be done multiple times each time the volume of activity changes in order to provide accurate data, as CVP analysis makes no distinction between variable costing and absorption costing income statements. A company expects to manufacture 7, units.

Its direct material costs are? The fixed overhead is estimated at? How much would each unit cost under both the variable method and the absorption method?

The variable cost per unit is? The absorption cost per unit is the variable cost? Variable costing only includes the product costs that vary with output, which typically include direct material, direct labor, and variable manufacturing overhead. Fixed overhead is not considered a product cost under variable costing. Fixed manufacturing overhead is still expensed on the income statement, but it is treated as a period cost charged against revenue for each period.

It does not include a portion of fixed overhead costs that remains in inventory and is not expensed, as in absorption costing. If absorption costing is the method acceptable for financial reporting under GAAP, why would management prefer variable costing? Advocates of variable costing argue that the definition of fixed costs holds, and fixed manufacturing overhead costs will be incurred regardless of whether anything is actually produced.

They also argue that fixed manufacturing overhead costs are true period expenses and have no future service potential, since incurring them now has no effect on whether these costs will have to be incurred again in the future. While the variable cost method helps management make decisions, especially when the number of units in ending inventory fluctuates, there are some disadvantages:. Under the absorption costing method, all costs of production, whether fixed or variable, are considered product costs.

This means that absorption costing allocates a portion of fixed manufacturing overhead to each product. Advocates of absorption costing argue that fixed manufacturing overhead costs are essential to the production process and are an actual cost of the product. They further argue that costs should be categorized by function rather than by behavior, and these costs must be included as a product cost regardless of whether the cost is fixed or variable. While financial and tax reporting are the main advantages of absorption costing, there is one distinct disadvantage:.

An ethical and evenhanded approach to providing clear and informative financial information regarding costing is the goal of the ethical accountant. Ethical business managers understand the benefits of using the appropriate costing systems and methods. Determining the appropriate costing system and the type of information to be provided to management goes beyond providing just accounting information.
