Standard Costing (Explanation) Introduction to Standard Costing. Standard costing is an important subtopic of cost accounting. Standard costs are usually associated with a manufacturing company's costs of direct material, direct labor, and manufacturing overhead.
The total standard costs are $1.55 million because the $50,000 charge is excluded. The small manufacturer is an S corporation, therefore no taxes are paid at the corporate level. Calculate the standard margin by dividing $0.45 million by $2 million in sales for a total of 22.5 percent. Both gross profit margin and standard margins measure profitability. Gross profit margin measures top-line profitability, or profitability before selling, general and administrative expenses are included.
