# Absorption Cost Accounting

Variable costing is a costing system under which those costs of production that vary with output are treated as product costs. This would usually include direct materials, direct labor and variable portion of manufacturing overhead.

In absorption costing, inventory is valued at full manufacturing cost . This has the effect of carrying over fixed costs from one period to another along with the closing stock. This distorts the trading results and vitiates the cost comparison. Difference in the size or magnitude of opening and closing stocks not only affects the unit cost of production but profit also in the case of absorption costing due to the impact of fixed cost. In the case of marginal costing, however, there is no such problem with regard to the size of opening and closing stocks. These other manufacturing expenses, which are collectively known as manufacturing overhead, are not distinguished as such for purposes of product costing under the technique of absorption costing. Regardless of their differences, they are also charged to the cost unit.

This can result in costs that remain unaccounted for on a company’s income statement, temporarily increasing a company’s apparent profitability on its balance sheet. I think this table might help show the differences between the two inventory valuable methods. Notice that all the costs are included in the final inventory valuation.

It avoids the separation of costs into fixed and variable elements which cannot be done easily and accurately. Separation of costs into fixed and variable components is not needed. Absorption costing is an advantage for companies that have a constant demand for products. It provides a simple and systematic costing tool for active businesses while taking into account the fluctuating turnover as costs are already fixed to the products.

Calculating absorbed cost helps companies determine the overall cost of making and bringing to market a single product line, brand, or item—and which of these are the most profitable. Add absorption rate to one of your lists below, or create a new one. An absorption rate of 6 indicates a balanced market, while the current figure for the area of 9.2 shows that it is a buyer’s market. The absorption method shows efficient as well as inefficient utilization of resources by indicating over-absorption or under-absorption of factory overheads.

## Absorption Costing Formula:

If the absorbed amount exceeds actual overhead, the difference would be called as “overapplied overhead”. If however, it falls short of actual overhead, the difference would be called ‘Under applied overhead”. If on a job 25 hours are spent then the absorption on the hob will be of \$0.2 x 25 hours, i.e. \$5. This method should be applied where the labour is the predominant factor of production. The expenses allocated to the production department e.g., salary of the departmental head, salary of departmental foremen, cost of indirect materials issued to the department, etc.

• When sales fluctuate but production remains constant, profit increases or decreases with the level of sales whether it is absorption costing or marginal costing, assuming that costs and prices remain constant.
• Variable costing only includes the product costs that vary with output, which typically include direct material, direct labor, and variable manufacturing overhead.
• Indirect costs are costs that are not directly traceable to an activity or product.
• Absorption costing considers direct materials, direct labor, variable manufacturing overhead and fixed manufacturing overhead as product costs.

Recall that selling and administrative costs are considered period costs and are expensed in the period occurred. The absorbed cost is a part of generally accepted accounting principles , and is required when it comes to reporting your company’s financial statements to outside parties, including income tax reporting.

## Problems With Absorption Costing

Fixed overhead is treated as a period cost and does not vary as the volume of inventory changes. This results in income increasing in proportion to sales, which may not happen under absorption costing. Under absorption costing, the fixed overhead assigned to a cost changes as the volume changes. Therefore, the reported net income changes with production, since fixed costs are spread across the changing number of units.

Look how much less the variable costing method values your inventory. This could be a major problem when it comes to marketing and pricing your products.

On the other hand, certain other items of manufacturing overhead such as power, fuel, royalty, sundry supplies, etc., increase or decrease as output increases or decreases. The same is true of depreciation if it is calculated on the basis of number of units produced or machine hours worked. Absorption cost accounting (also known as the “Cost-Plus” approach), is a method that is centered upon the allocation of Manufacturing Cost to the product. This method is important for situations when a company needs to decide if it can be competitive in a market, or when the company has control over the pricing in general.

## Absorbed Costs Vs Variable Costs

As long as the company could correctly and accurately calculate the cost, there is a high chance that the company could make the correct pricing for its products. Absorption costing is also known as full absorption costing or full costing. On the downside, things can get a little tricky when it comes to making an exact calculation of absorbed costs, and knowing how much of them to include. If all of the variables are not considered carefully , it can give you misleading results. Absorption costing is the acceptable reporting method under GAAP. Costs are first apportioned to cost centres, where they are absorbed using absorption rates.

Variable overhead costs directly relating to individual cost centers such as supervision and indirect materials. You need to allocate all of this variable overhead cost to the cost center that is directly involved.

The cost units are made to bear the burden of full costs even though fixed costs are period costs and have no relevance to current operations. Under variable costing, however, only variable costs are treated as product costs. Absorption costing includes anything that is a direct cost in producing a good as the good as the cost base. Absorption costing is also called full costing as all costs including fixed overhead retained earnings charges are included as product costs. As opposed to the other alternative costing method called variable costing, every expense is allocated to products manufactured within or not they are sold. Absorption costing is a managerial accounting cost method of expensing all costs associated with manufacturing a particular product and is required for Generally Accepted Accounting Principles external reporting.

## Treatment Of Absorption Costing In Books

Absorption costing is in accordance with GAAP, because the product cost includes fixed overhead. Variable costing considers the variable overhead costs and does not consider fixed overhead as part of a product’s cost. It is not in accordance with GAAP, because fixed overhead is treated as a period cost and is not included in the cost of the product.

## Arguments In Support Of Absorption Costing

Absorption costing is useful if there is only one product, there is no inventory and overhead recovery rate is based o normal capacity instead of the actual level of activity. Two distinguishing feature absorption costing is that fixed factory expenses are included in the unit cost and inventory value. Under this technique QuickBooks of cost, the cost is made up of direct cost plus overhead costs absorbed on some suitable basis. In this technique, cost per unit remains the same only when the level of output remains the same. But when the level of output changes the cost per unit also changes in the presence of fixed cost which remains constant.

Determining the appropriate costing system and the type of information to be provided to management goes beyond providing just accounting information. The costing system should provide the organization’s management with factual and true financial information regarding the organization’s operations and the performance of the organization. Unethical business managers can game the costing system by unfairly or unscrupulously influencing the outcome of the costing system’s reports. Managers may find it easier to understand variable costing reports because overhead changes with the cost driver. The car dealership covers most of its fixed operating costs with gross profits from service and parts operations, but this 90% absorption rate is unusual in the industry. The mangers can show inflated profit and not the real one as he can easily increase the operating income of a particular period by boosting the production even if there is no actual demand for that product. The method used was the absorption costing, identifying all costs per vehicle.
