Cost Driver Examples -
Introduction In activity-based costing (ABC) and traditional cost accounting, a cost driver is any factor that causes a change in the cost of an activity. Identifying the correct cost drivers is essential for accurate product costing, budgeting, and strategic decision-making. Below is a structured breakdown of common cost driver examples, categorized by business function and cost behavior. 1. Activity-Based Cost Drivers (by Business Function) These drivers link overhead costs to specific operational activities.
| | Typical Use Case | |------------|----------------------| | Direct labor hours | Labor-intensive assembly lines (e.g., apparel, handcrafted goods). | | Machine hours | Automated manufacturing (e.g., automotive parts, plastics). | | Units produced | Uniform products with identical resource consumption per unit. | | Direct material cost | Industries where raw material value drives handling and storage overhead. | | Square footage | Facility-related costs (rent, utilities, janitorial) allocated to departments. | 3. Customer & Sales Cost Drivers For analyzing profitability by customer or channel. cost driver examples
| | Example Cost Driver | Rationale | |--------------|------------------------|----------------| | Purchasing | Number of purchase orders | Each order incurs processing, shipping, and inspection costs regardless of order size. | | Production setup | Number of setups | Time and labor to reconfigure machinery before a batch run. | | Quality control | Number of inspections | Directly correlates with testing time and defect detection effort. | | Machine maintenance | Machine hours | More runtime leads to higher wear, lubricants, and technician labor. | | Customer service | Number of support calls | Each call consumes agent time and system resources. | | Packaging | Number of units packed | Direct variable relationship with materials and handling labor. | | Shipping | Weight or volume of goods | Fuel, handling, and carrier costs scale with physical measures. | | Order processing | Number of customer orders | Administrative steps (entry, verification, invoicing) per order. | 2. Volume-Based Cost Drivers (Traditional Costing) Simpler models use single, volume-based drivers—best when overhead is proportional to production quantity. | | Machine hours | Automated manufacturing (e
