How to Calculate Your Amazon FBA Landed Cost from China — 2026 Formula + Worked Example
Ask five Amazon sellers how they calculate landed cost. You'll get five different answers — and at least three of them are leaving money on the table.
Some track factory price only. Some add the freight invoice. Almost nobody accounts for the Amazon inbound placement fee until it shows up on their Seller Central dashboard.
Here's the formula, the real numbers behind each line item, and a worked example you can copy for your own SKUs.
The Landed Cost Formula
Landed cost per unit is the total of every expense from the factory floor to the Amazon warehouse door — divided by the number of units in the shipment.
Landed Cost Per Unit =(Factory Cost + China Pickup + Freight + Insurance + Customs Duty+ Additional Tariffs + Bond Fee + ISF Filing + Destination Handling+ Trucking to FBA + Amazon Placement Fee) ÷ Total UnitsEach line item matters. Skip one, and your margin projection is fiction.
Line-by-Line Breakdown with July 2026 Estimates
Let's use a concrete shipment: 1,000 units of kitchen gadgets. Factory in Yiwu. Destination: Amazon ONT8 in Southern California. Carton count: 50 cartons, total 2.5 CBM, 500 kg.
| Line Item | Cost | Per Unit (÷1000) | Notes |
|---|---|---|---|
| Factory cost (EXW) | $8,000 | $8.00 | Negotiated supplier price |
| China pickup (Yiwu → port) | Free | $0.00 | CDT warehouses pickup at no charge |
| Sea freight (LCL DDP) | $210 | $0.21 | 2.5 CBM × $84/CBM |
| Cargo insurance | $24 | $0.02 | 0.3% of declared value |
| US customs duty (Section 301) | $520 | $0.52 | 6.5% on $8,000 declared value |
| Additional China tariffs | $580 | $0.58 | Current Section 301 surcharge |
| Customs bond (single entry) | $85 | $0.09 | Required for shipments over $2,500 |
| ISF filing | $35 | $0.04 | Mandatory 10+2 data |
| Destination handling + CFS | $150 | $0.15 | Unloading at LAX, document fees |
| Trucking LAX → ONT8 | $350 | $0.35 | 60 miles, shared truck |
| Amazon FBA placement fee | $120 | $0.12 | Per-unit inbound placement |
| TOTAL LANDED COST | $10,074 | $10.07 | |
| Landed cost as % of factory price | 25.9% |
That's the number most sellers don't see coming. A 25.9% uplift from factory price to Amazon-ready inventory. If you were using factory cost alone as your landed cost, you'd be underpricing by $2.07 per unit.
The Three Sellers Who Get This Wrong
Seller A only accounts for factory cost + freight invoice. His calculation: 1,500 = 10.07. He's losing 570 on this shipment.
Seller B accounts for everything except Amazon's placement fee. His 120 unaccounted.
Seller C runs the full formula. His $10.07 estimate is accurate to the cent. He prices accordingly and his margin projections hold.
How to Cut Your Landed Cost — The Levers You Control
You can't negotiate tariffs. You can't change Amazon's placement fee. But you can control three things:
Consolidation: if you're shipping 2.5 CBM from three suppliers, consolidate into one shipment at a China warehouse. Handling cost stays the same, but freight per CBM drops when volume increases.
Freight mode: at 2.5 CBM, LCL sea freight is the right call. At 12+ CBM, switching to FCL drops your per-unit freight by roughly 30%. At 500 kg, air freight is faster but costs roughly 0.21 for sea.
Forwarder selection: some forwarders consolidate the tariff line item into the freight invoice — you don't see the breakdown. A forwarder who gives you a line-by-line DDP quote lets you verify each charge. That transparency matters when you're projecting margins.
Run your own numbers. Take your factory price, your CBM, your destination — and put them through the formula above. If your forwarder can't give you a transparent line-by-line quote, send your shipment details through the contact form on this page. You'll get a real DDP landed cost breakdown in under 2 hours. No commitment, no minimum.
