What this tool estimates
Landed cost spreads shipment-level costs across the units in the shipment: product cost plus freight, customs duty, insurance, and other receiving fees, divided by units. It answers what one unit truly costs once it is in your warehouse, which is the cost figure your margin and pricing decisions should use.
Inputs to verify
Match the freight figure to your actual freight basis (FOB, CIF, and similar terms differ). Confirm the duty basis your customs regime uses; percentage mode here applies duty to goods value only. Include one-off receiving and brokerage fees in the other-fees field so they are not forgotten.
Costs that are per shipment, not per unit
Freight, duty, insurance, and receiving fees are usually incurred per shipment. A small top-up order carries the same shipment costs over fewer units, which raises landed cost — compare order sizes before splitting a shipment.
