What is Cost Accounting?
Cost accounting is the branch of managerial accounting that captures, classifies, allocates, and analyzes the costs of products, services, processes, and activities. Its purpose is to provide management with the cost information needed for pricing, budgeting, cost control, performance evaluation, and strategic decisions. It does not follow GAAP/IFRS the way financial accounting does.
How It Works
- Classify costs by behavior (fixed, variable, mixed), function (production, marketing), or traceability (direct, indirect).
- Choose a costing method: job order, process, activity-based, standard, or target costing.
- Allocate overhead using appropriate cost drivers.
- Calculate unit cost and use it for pricing and profitability analysis.
- Compare actual costs to standards or budgets and investigate variances.
Saudi Context
Saudi manufacturers (petrochemicals, food, building materials), construction firms, and large F&B operators rely on cost accounting to manage margins. ZATCA may inspect cost build-ups during transfer pricing audits, particularly for related-party manufacturing arrangements within multinational groups headquartered in Saudi Arabia.
Example
A furniture manufacturer using job order costing accumulates SAR 4,500 of direct materials, SAR 2,000 of direct labor, and SAR 1,500 of allocated overhead for Job #2057. The total unit cost is SAR 8,000, used to set a selling price of SAR 12,000 (50% markup).
