How do I calculate landed cost per unit?
Combine supplier value, international freight, insurance, customs duty, import tax, clearance fees, and quantity into one comparable unit cost.
Short answer
Add goods, international freight, insurance, duty, import tax, brokerage, and other destination costs, then divide the all-in landed total by the number of usable units. Keep the customs-value and import-tax bases editable because they vary by destination and product.
