How the landed cost calculator works
Freight and customs fees are divided by the number of units; duty and tariffs are applied to the supplier price; the four pieces are added to give your true per-unit cost. Add a planned selling price to see the gross margin and markup that cost leaves you before marketplace fees.
Frequently asked questions
What is included in landed cost?
Product price, international freight, insurance, import duty and tariffs, customs brokerage, and any port or handling charges — everything up to your door. Marketplace fees and domestic fulfilment come after.
Is duty charged on freight too?
In the US duty is normally assessed on the customs value of the goods (usually the FOB price), not on freight. The EU and UK include freight and insurance (CIF) in the dutiable value — raise the duty rate slightly to approximate that.
Why does my supplier's price look nothing like my real cost?
Because freight, duty, and fees often add 30–60%. A $4.20 unit can easily land at $6.50, which is why pricing from the invoice alone overstates margin.
