täyskustannuslaskentaan

Täyskustannuslaskenta, known in English as full cost accounting or absorption costing, is a method of cost accounting where all manufacturing costs, including both direct and indirect costs, are absorbed into the cost of a product. This means that all costs associated with producing a good or service, such as direct materials, direct labor, and manufacturing overhead (both variable and fixed), are included in the cost of inventory. Non-manufacturing costs, such as selling, general, and administrative expenses, are treated as period costs and are expensed in the period they are incurred, rather than being included in the cost of goods sold until the product is sold.

The primary advantage of full cost accounting is that it presents a more complete picture of the total cost of production. It adheres to generally accepted accounting principles (GAAP) and international financial reporting standards (IFRS) for external financial reporting. This method ensures that all costs are accounted for when valuing inventory on the balance sheet and when calculating the cost of goods sold on the income statement. However, it can sometimes obscure the behavior of variable costs and may not be as useful for internal decision-making, particularly when considering short-term pricing or production decisions where fixed costs are less relevant. Variable costing, which only includes variable manufacturing costs in product costs, is often preferred for internal management purposes.
