Direct and Indirect CostsDirect and Indirect CostsDirect costs

• Costs that can beeasily and conveniently traced to a product or department.

• Example: cost of paint in the paint department of an automobile assembly plant.

Indirect costs

• Costs that must be allocated in order to be assigned to a product or department.

• Example: cost of national advertising for an airline is indirect to a particular flight.

2-47

• A cost can be direct to the department, but indirect to units of product produced in the department.– Example: department manager’s salary.

• Tracing costs directly to departments or products helps to identify and eliminate non-value added costs.

Opportunity CostOpportunity Cost

The potential benefit that is given up when one alternative is selected over another.– Example: If you were

not attending college,you could be earning$20,000 per year. Your opportunity costof attending college for one year is $20,000.

2-51

Sunk CostsSunk Costs

All costs incurred in the past that cannot be changed by any decision made now or in the future are sunk costs. Sunk costs should not be considered in decisions.

– Example: You bought an automobile that cost $12,000 two years ago. The $12,000 cost is sunk because whether you drive it, park it, trade it, or sell it, you cannot change the $12,000 cost.

2-52

Differential CostsDifferential Costs

Costs that differ between alternatives.

Example: You can earn $1,500 per month in yourhometown or $2,000 per month in a nearby city.

Your commuting costs are $50 per month in yourhometown and $300 per month to the city.

What is your differential cost? $300 - $50 = $250

Marginal Costs and Average Marginal Costs and Average CostsCosts

The total cost toproduce a quantity

divided by thequantity produced.

Marginal and average costs arelargely a function of cost behavior
