Cost Versus Price Categories that make up list price –Direct Costs - costs directly related to making the product. Includes labor, scrap, warranty (typically adds 25% to 40% to component cost) –Gross Margin - overhead that cannot be billed to one product. Includes R&D, marketing, sales, manufacturing equipment maintenance, building rental, cost of financing, pretax profits, and taxes (typically 45% to 65% of average selling price)
Cost Versus Price (continued) Cost * (1 + Direct costs) (1 - Average discount) * (1 - Gross margin) List price =

Sustainability Maintains functionality and user satisfaction over an extended life cycle Compatible with existing and emerging standards Tracks positive pricing and availability trends in technology (e.g., design includes new, innovative IC’s that are likely to be produced competitively in volume)
Sustainability (continued) Position in market evolves by freely encompassing new technology (design is resistant to being outdated by competing, incompatible technology) Design is low maintenance (service costs are controlled) Quality control in part supported by design for test features
