The traditional way of determining product cost is:

1. Cost-plus pricing, which includes cost of goods sold and adds a profit margin on top
2. Market-driven pricing, which takes the market price and works backwards by reducing the margins and supply chain related costs
3. Cost-plus pricing, which adds cost of goods sold and selling, general and administration expenses, and adds a profit margin on top
4. Marginal-cost pricing, which takes cost of goods sold and adds a profit margin on top
5. None of the above are traditional ways to determine product costs
