Landed Cost Calculator

Last updated: 2026-10-02

What this tool does

The factory's unit price is only the beginning. By the time goods clear your local customs and reach your warehouse, you have paid for domestic freight inside China, international freight, import duty, and a handful of smaller fees — and the real per-unit cost can be 30–80% higher than the quote on the proforma invoice. This calculator adds it all up and shows you the true landed cost per unit, so you can set retail prices and evaluate supplier quotes with honest numbers. The interactive widget appears above this text.

Inputs

• Unit price (USD) — the per-unit price quoted by your supplier.
• Quantity — how many units you are buying.
• Domestic freight (USD total) — moving the goods from the factory to the port or airport inside China. Often small, but not zero.
• International freight (USD total) — the main shipping leg from China to your country. Use a forwarder quote here, or our shipping cost estimator for a rough figure.
• Duty rate (%) — the import duty percentage for your product in your country. Check your customs authority's tariff lookup by HS code for the real number.
• Other fees (USD total) — everything else: customs brokerage, port handling, insurance, inspections, warehousing. Lump them together if you don't have them itemized yet.

How the estimate works

The calculator works through the cost stack step by step, and shows you a line-by-line breakdown:

1. Goods total = unit price × quantity
2. Duty = goods total × duty rate
3. Grand total = goods total + domestic freight + international freight + duty + other fees
4. Per-unit landed cost = grand total ÷ quantity

The breakdown matters more than the final number. It shows you where the money goes — many buyers discover that freight, not duty, is what kills their margin, or that doubling the order quantity barely moves the per-unit cost because freight dominates. Seeing the stack lets you negotiate the right line: push the forwarder on freight, or the supplier on unit price, depending on which line is actually hurting you.

Disclaimer

These are estimates for planning purposes only. Actual duty depends on the correct HS classification of your product and on customs valuation rules in your country — misclassified goods can be reassessed at the border. Freight quotes move with fuel prices and seasons, and "other fees" are easy to underestimate on a first shipment. Treat the output as a starting point, then refine each line with real quotes before you commit.
