Build cost from the approved specification and named delivery point. Include material, labor, waste, overhead, export packaging, labels, testing, inspection, sample recovery, inland transport, handling, documents, bank charges, finance, commissions, and risk-based contingency. Separate costs by Incoterm so a CIF quote never uses an FOB model.
Illustrative FOB costing for 1,000 units
Assume factory cost PKR 1,800,000; packaging 120,000; testing 45,000; haulage 85,000; forwarding and documents 110,000; and finance, bank, and contingency 90,000. Total cost is PKR 2,250,000. For 12% margin on selling price, divide by 0.88: PKR 2,556,818. At an illustrative PKR 280/USD, that is about USD 9,131, or USD 9.13 per unit FOB. Replace all assumptions with current quotations; this is not a market price or forecast.
State currency, quantity, Incoterm and named place, rule edition, lead-time trigger, packing, validity, payment, inspection, and exclusions. Revalidate volatile inputs before acceptance. Margin on selling price differs from markup on cost, so label the formula.
