When it comes to financial reporting, companies have to choose between two methods: absorption costing and variable costing. This decision can have a significant impact on the bottom line and lead to different financial ratios and metrics. Both methodologies have their pros and cons, but the question is, which one is more commonly accepted by Generally Accepted Accounting Principles (GAAP)?
Absorption costing is a traditional approach that assigns all manufacturing costs to the products, including fixed overhead expenses. This method is also known as full costing or comprehensive costing because it accounts for all expenses, not just those that vary with production levels. However, variable costing only considers direct costs, such as raw materials, labor, and variable overhead.
Although both methods are allowed under GAAP, they can lead to different results in terms of inventory valuation, net income, and cost of goods sold. Therefore, it’s crucial for businesses to understand the differences between absorption and variable costing before choosing a method that aligns with their business goals and strategies. In this article, we’ll explore the GAAP guidelines for absorption and variable costing and how they impact financial statements.
Overview of Absorption and Variable Costing
Absorption and variable costing are two different methods used in managerial accounting to allocate manufacturing costs to products. Absorption costing is a traditional method of costing where all manufacturing costs are fully absorbed into the product’s cost. On the other hand, variable costing is a modern approach that only assigns variable manufacturing costs to products.
Absorption costing is mandated by the Generally Accepted Accounting Principles (GAAP) and is required for external financial reporting. Companies using absorption costing must allocate all production costs, including direct materials, direct labor, and overhead, to their products. It means that all fixed manufacturing costs, such as rent, depreciation, insurance, and utilities, are part of the cost of goods manufactured. As a result, if a company produces more units of products, the fixed manufacturing costs are spread over more units, reducing the cost per unit.
Variable costing, also known as direct costing, is a method where only the variable costs, such as direct materials, direct labor, and variable overhead, are allocated to the product. Fixed manufacturing costs, such as rent and utilities, are considered period costs and are not assigned to the cost of goods sold. As a result, variable costing is useful for internal managerial accounting purposes, such as budgeting, planning, and decision-making.
Advantages and Disadvantages of Absorption and Variable Costing
- The biggest advantage of absorption costing is that it complies with GAAP and is necessary for external financial reporting. It also provides a comprehensive view of the costs incurred in producing a product.
- Variable costing is useful for internal managerial accounting purposes, as it provides information about the cost of manufacturing a product without allocating any of the fixed costs that may not be related to production volume.
- Absorption costing can lead to overpriced products if the production volume is low, as fixed costs are included in the product’s cost.
- Variable costing can lead to underpricing products if the production volume is not sufficient to cover the fixed costs that are not part of the product’s cost.
Difference between Absorption and Variable Costing
The main difference between absorption and variable costing is how fixed manufacturing costs are accounted for. In absorption costing, fixed manufacturing costs are part of the cost of goods sold, while in variable costing, they are considered period costs and are not assigned to the cost of goods sold. As a result, the cost per unit is different between the two methods, and the inventory valuation may also be different.
Conclusion
| Method | Advantages | Disadvantages |
|---|---|---|
| Absorption Costing | Complies with GAAP, provides a comprehensive view of costs | Can lead to overpriced products, may not be suitable for internal managerial accounting purposes |
| Variable Costing | Useful for internal managerial accounting purposes, provides information on variable costs | May lead to underpricing products, cannot be used for external financial reporting purposes |
Both absorption and variable costing have their advantages and disadvantages, and the choice of method depends on the company’s objectives and goals. Companies using absorption costing must adhere to GAAP and use the method for external financial reporting. Variable costing is suitable for internal managerial accounting purposes, such as budgeting, planning, and decision-making.
Historical Context of Costing Methods in GAAP
Costing methods have played a crucial role in the development of Generally Accepted Accounting Principles (GAAP). The need for a consistent and reliable financial reporting system arose due to the growth of modern business enterprises in the early 20th century. Prior to GAAP, accountants used various methods to calculate costs, leading to discrepancies and confusion in financial reporting. To address this issue, GAAP standardizes accounting principles, including costing methods, to ensure consistency and accuracy of financial reporting.
Traditional Costing Methods in GAAP
- Absorption Costing: Absorption costing, also known as full costing, includes all direct and indirect costs associated with production, such as direct materials, direct labor, and overhead. This method assigns a portion of indirect costs to each unit of production, creating a fixed and variable portion of cost per unit. This method is suitable for long-term planning and decision-making, as it considers all costs associated with production. Absorption costing is commonly used in GAAP financial reporting.
- Variable Costing: Variable costing, on the other hand, only includes the direct costs of production, such as direct materials and direct labor. This method does not assign indirect costs to each unit of production, but instead considers them as period costs that are expensed as incurred. Variable costing is useful for short-term decision-making, as it provides a clear picture of the costs associated with each unit of production. However, this method is not commonly used in GAAP financial reporting.
Changes in Costing Methods in GAAP
Over the years, there have been debates about the best costing method to use in financial reporting. The rise of service-oriented and knowledge-based businesses has raised questions about the relevance of traditional costing methods. As a result, GAAP has undergone several changes to incorporate more relevant costing methods, such as activity-based costing. This method assigns costs based on the activities that drive the costs, providing a more accurate allocation of indirect costs.
Conclusion
Costing methods have evolved over time in response to changes in the business landscape and advancements in accounting practices. GAAP has played a crucial role in standardizing these methods to ensure consistency and accuracy in financial reporting. While traditional costing methods continue to dominate, newer methods such as activity-based costing are gaining more traction in financial reporting. Ultimately, the choice of costing method will depend on the specific needs of a business and its stakeholders.
| Traditional Costing Methods | Activity-Based Costing |
|---|---|
| Absorption Costing | Assigns costs based on activities that drive costs |
| Variable Costing | Provides more accurate allocation of indirect costs |
As businesses continue to evolve, so will the methods of costing. It is important for accountants and financial professionals to stay updated with the latest developments in accounting practices to provide accurate and reliable financial reporting.
Advantages and Disadvantages of Absorption Costing
Absorption costing is a widely used accounting method that assigns all manufacturing costs to the cost of a product. In this method, all expenses, including direct materials, direct labor, and both variable and fixed manufacturing overheads, are allocated to each unit of production. The calculation of the product’s cost is done by dividing the total cost by the number of units produced. However, while absorption costing has several benefits and drawbacks that can affect the company’s financial health and decision-making process, it is also important to consider the different contexts in which it is applied.
Below are the several advantages and disadvantages of absorption costing:
- Advantages:
- Better reflects actual cost of products: Absorption costing takes into account all manufacturing costs, providing an accurate measurement of the product’s cost. This is important for budgeting, pricing, and decision-making purposes.
- Complies with Generally Accepted Accounting Principles (GAAP): Absorption costing is the only inventory valuation method in compliance with GAAP. Required for external financial reporting purposes, this method can help avoid legal issues and penalties for non-compliance.
- Increases profitability: Absorption costing encourages the manufacture of more units in order to lower the per unit fixed costs. This can increase profitability by improving efficiency.
- Disadvantages:
- May result in overvalued inventory: Due to the inclusion of fixed costs, such as rent, depreciation, and insurance, absorption costing can overstate the ending inventory cost. This can lead to incorrect financial statements during periods of low sales or overproduction.
- May incentivize unnecessary production: Because the absorption costing method allocates fixed overhead costs to each unit, it can encourage the production of excess inventory to absorb overhead costs. Excess inventory carries a cost of storage and maintenance, which can lower profits.
Conclusion
Despite its potential drawbacks, absorption costing remains a critical accounting method due to its alignment with GAAP compliance, suitability for external financial reporting, and the accuracy of determining a product’s actual cost. However, it is important for managers to understand the limitations and be mindful of the potential impacts of the fixed cost allocation method on their decisions using financial statements.
| Advantages | Disadvantages |
|---|---|
| Better reflects actual cost of products | May result in overvalued inventory |
| Complies with GAAP | May incentivize unnecessary production |
| Increases profitability |
Overall, while absorption costing may not be perfect for all business situations, the advantages and disadvantages highlight the important factors to consider when deciding on an inventory valuation method. Companies should evaluate the pros and cons of each method before deciding on the appropriate approach for their business operations.
Advantages and Disadvantages of Variable Costing
Variable costing is a cost accounting method where only variable manufacturing costs are included in the cost of a product. This method is different from absorption costing, which includes both variable and fixed manufacturing costs in the product cost. When deciding which method to use, it is essential to consider the advantages and disadvantages of each approach.
- Advantages of Variable Costing:
- Provides better information for internal decision-making: Variable costing provides a clearer picture of the costs and profitability of a product since it only considers variable costs. This approach helps management make better decisions in areas like pricing, product mix, and cost control.
- Reduces the impact of fixed costs on reported profits: In times of decreasing sales, absorption costing may result in low profitability since fixed overhead costs are allocated to the cost of the product. On the other hand, with variable costing, fixed costs are expensed as period costs, reducing their impact on profits and providing a better reflection of reality.
- Helpful in evaluating production efficiency: Since variable costing emphasizes variable manufacturing costs, it can provide a better understanding of the relationship between production costs and output. This information can be used to evaluate production efficiency and identify opportunities for cost savings.
- Disadvantages of Variable Costing:
- May lead to under-pricing: Since variable costing does not apply fixed production overhead to the cost of a product, the product may be under-priced, leading to low profitability or even losses.
- May not accurately reflect total production costs: Variable costing does not consider fixed production overhead in the cost of a product, which may lead to inaccurate accounting of the true cost of production.
- Not accepted for external reporting: The Generally Accepted Accounting Principles (GAAP) requires companies to use absorption costing for external reporting since it provides a more accurate reflection of total production costs.
Example of Variable Costing versus Absorption Costing:
Suppose a company produces a product, and the total costs are $100,000, with variable costs of $70,000 and fixed costs of $30,000.
| Variable Costing | Absorption Costing | |
|---|---|---|
| Variable Manufacturing Costs | $70,000 | $70,000 |
| Fixed Manufacturing Costs | $0 | $30,000 |
| Product Cost | $70,000 | $100,000 |
In this example, variable costing results in a lower product cost, only including variable costs, while absorption costing includes fixed overhead costs. This difference in the cost of the product can have implications for decision-making regarding pricing, production, and profitability.
Implementation of Absorption Costing under GAAP
GAAP (Generally Accepted Accounting Principles) allows companies to choose between two cost accounting methods: absorption costing and variable costing. In absorption costing, all manufacturing costs, including fixed overhead costs, are allocated to the units produced. In variable costing, only the variable costs directly tied to the production of the product are allocated to the units produced. Here we will discuss the key aspects of implementing absorption costing under GAAP.
- Identifying Direct and Indirect Costs: To implement absorption costing, it’s crucial to determine the direct and indirect costs to produce a product. Direct costs are those that can be easily traced back to a specific product, such as raw materials and labor. Indirect costs, also known as overhead costs, cannot be directly traced to a specific product. These costs include rent, utilities, and depreciation of equipment.
- Assigning Indirect Costs: The next step is to allocate the indirect costs to the units produced. This can be done using a predetermined overhead rate based on the estimated usage of the overhead resources. For example, if the estimated annual manufacturing overhead costs are $1,000,000 and 100,000 units are expected to be produced, then the predetermined overhead rate would be $10 per unit.
- Calculating Cost of Goods Sold: Once the indirect costs have been assigned to the units produced, the cost of goods sold can be calculated. This is done by adding the direct costs and the allocated indirect costs to determine the total production costs. The cost of goods sold is then calculated by subtracting the ending inventory from the total production costs.
While absorption costing is the preferred method under GAAP, companies may elect to use variable costing. However, they must disclose in their financial statements that they are using this method and provide a reconciliation of the cost of goods sold under variable costing to cost of goods sold under absorption costing.
It’s essential for companies to understand the requirements and implications of using absorption costing under GAAP. Proper implementation can provide valuable insights into the costs and profitability of a company’s products, while ensuring adherence to accounting standards.
| Advantages of Absorption Costing | Disadvantages of Absorption Costing |
|---|---|
| Reflects the true cost of production by including all manufacturing costs in the cost of goods sold. | Can result in overpricing of products if production volume is low and production costs are high. |
| Provides a better picture of inventory costs and the impact on profitability. | May encourage overproduction to reduce fixed overhead costs per unit, leading to excessive inventory levels. |
| Meets GAAP requirements, allowing for consistency in financial reporting and easier comparison between companies. | May not be appropriate for decision-making related to pricing and product mix due to the distortion of fixed costs over a range of production levels. |
Understanding the advantages and disadvantages of absorption costing can help companies make informed decisions about which cost accounting method to use.
Implementation of Variable Costing under GAAP
Variable costing is an accounting method where only variable manufacturing costs are included in the cost of goods sold (COGS) while fixed costs are treated as expenses of the period incurred. Unlike absorption costing, which includes all manufacturing costs in COGS, variable costing allows managers to better understand the impact of sales and production on profitability by clearly separating fixed and variable costs. However, the implementation of variable costing under GAAP requires adherence to specific guidelines.
- Variable costing can only be used for internal reporting purposes, while absorption costing is mandatory for external financial reporting under GAAP.
- Fixed manufacturing costs can be included as a period expense or capitalized as an asset if they meet certain criteria, such as being directly related to future production.
- Income statements must show variable COGS, fixed period expenses, and a reconciliation of beginning and ending inventory levels.
It is important to note that while variable costing provides a more accurate representation of the impact of production and sales decisions on profitability, it has limitations. Because fixed manufacturing costs, such as plant depreciation, are excluded from inventory, unit costs and valuation of inventory may fluctuate widely from period to period. Additionally, external financial reporting requirements necessitate the use of absorption costing, making it difficult to reconcile internal and external reports.
Overall, the implementation of variable costing under GAAP requires careful consideration of the guidelines and limitations surrounding the use of the method. While it may provide valuable insight into the true costs of production and sales, its use for internal reporting purposes only limits its utility in financial decision-making.

Industry-Specific Considerations for Costing Methods in GAAP
While absorption and variable costing methods are generally accepted in GAAP, there are industry-specific considerations that should be taken into account when determining which method to use. These considerations include:
- Manufacturing Industry: The manufacturing industry has a high level of fixed costs due to capital-intensive production processes. For this reason, absorption costing may be the preferred method as it allocates fixed costs to each unit of production, providing a more accurate picture of the true cost of each item.
- Retail Industry: In the retail industry, products are purchased from suppliers and sold directly to customers, with no production process in between. For this reason, variable costing may be the preferred method as it only includes variable costs, such as the cost of goods sold, in the calculation of profit.
- Service Industry: The service industry does not have the same level of fixed costs as the manufacturing industry. For this reason, variable costing may be the preferred method as it more accurately reflects the true cost of providing services.
Variable Costing vs Absorption Costing: Pros and Cons
Both variable costing and absorption costing have their pros and cons.
Variable costing is a simpler method that only includes variable costs in the calculation of profit. This method is easier to understand and use than absorption costing, but it can lead to distorted profit margins when fixed costs are high. Variable costing is often used in industries where fixed costs are low or where it is difficult to accurately allocate and track fixed costs.
Absorption costing is a more complicated method that includes both variable and fixed costs in the calculation of profit. This method provides a more accurate picture of the true cost of production and can help management make better decisions about pricing and product mix. However, absorption costing can also lead to distorted profit margins in industries with high levels of fixed costs.
Comparison of Variable Costing and Absorption Costing
| Variable Costing | Absorption Costing | |
|---|---|---|
| Description | Only variable costs included in cost of goods sold and calculation of profit | Both variable and fixed costs included in cost of goods sold and calculation of profit |
| Usage | Preferred method in industries with low fixed costs or where fixed costs are difficult to allocate and track | Preferred method in industries with high levels of fixed costs, such as manufacturing |
| Advantages | Simple and easy to use | Provides a more accurate picture of the true cost of production |
| Disadvantages | May distort profit margins when fixed costs are high | May distort profit margins when fixed costs are high |
When choosing between variable costing and absorption costing, it is important to take industry-specific considerations and the pros and cons of each method into account. By doing so, management can make better decisions about pricing, product mix, and resource allocation, ultimately leading to greater profitability and success for the business.
