What Is Landed Cost?

Landed cost is the total cost to acquire one unit of inventory at your receiving dock — not just the supplier quote. It's the number every buyer should know before calculating a margin, setting a price, or approving a purchase order.

Most operators track "product cost" — the price on the invoice. But the invoice is just the starting point. By the time your product clears customs and arrives at your warehouse, you've paid for freight, insurance, duty, brokerage, and a stack of port fees. Miss any of these, and your margin math is wrong.

The formula: Landed Cost = Purchase Price + Freight + Customs Duty + Insurance + Brokerage + Port Fees

Example: You source a product at $5.00/unit from China. After freight ($0.90), 6% duty ($0.30), insurance ($0.02), brokerage ($0.40), and port fees ($0.18), your true landed cost is $6.80 — 36% higher than your supplier price. If you set your retail price at $12, you thought you had a 58% margin. Your actual margin is 43%.

Why Your Real Margin Is Lower Than You Think

Margin math done on supplier price alone will consistently overstate profitability. The gap gets worse as you move product further — China imports typically carry 25-40% overhead above product cost; Mexico truck imports run closer to 8-15%.

Freight mode matters enormously. Air freight to the US from Asia costs 4-6× more per pound than ocean LCL. If you're air-freighting to meet a stockout, your margin on those units takes a real hit — one many operators don't account for.

Hidden Costs Most Importers Miss

First-mile charges: Getting product from your factory to the export port. Often $50-200 per shipment.
ISF (Importer Security Filing): Required for ocean imports to the US. Typically $50-100 per shipment.
Destination drayage: Trucking from the port to your warehouse or 3PL. $200-600 depending on distance.
Customs examination fees: If CBP selects your shipment for exam, add $300-1,500+.
Demurrage & detention: If your container sits at port more than the free days, charges start accruing fast — $100-300/day.
FBA receiving / 3PL prep: If you ship to Amazon FBA or a 3PL, add receiving, labeling, and prep fees.
Currency risk: If you pay suppliers in RMB or EUR, exchange rate moves between PO and payment can add 1-3%.

Frequently Asked Questions

What is landed cost?

Landed cost is the total cost of a product by the time it reaches your warehouse or fulfillment center. It includes the purchase price, freight and shipping, customs duties, insurance, customs brokerage fees, and port or handling charges. Landed cost gives you the true cost of your inventory — not just the supplier price.

How do you calculate landed cost?

Landed cost = Purchase price + Freight cost + Customs duty + Insurance + Customs brokerage + Port/handling fees. Each component is calculated per unit. Freight is estimated based on weight, shipping mode, and origin/destination. Duty is calculated as duty rate × product value (FOB basis for US imports).

What is a typical customs duty rate for China imports?

US duty rates for China imports vary widely by HS code — from 0% for some raw materials to 25%+ for electronics and manufactured goods subject to Section 301 tariffs. The average for consumer goods is roughly 6-12% before Section 301 tariffs. Always verify your specific HS code at the USITC HTS database.

What is the difference between FOB and CIF for duty calculation?

FOB (Free On Board) is the product price before shipping. CIF (Cost, Insurance, Freight) includes shipping and insurance. The US calculates customs duty on the FOB value — so you pay duty on the product cost only. Other countries (including most EU and Asian nations) use CIF as the customs value, meaning you pay duty on the full shipped value including freight and insurance.

How accurate is this landed cost calculator?

This calculator provides estimates based on industry-average freight rates, typical customs brokerage fees, and standard insurance rates. Actual costs vary based on your carrier contracts, forwarder relationships, port of entry, and commodity type. Use these estimates for planning and margin analysis — always get actual quotes for large purchase decisions.

What hidden costs do most importers miss?

The most commonly missed costs are: (1) First-mile charges from supplier to export port, (2) Destination drayage from port to warehouse, (3) ISF (Importer Security Filing) fee ~$50-100, (4) Customs exam fees if your shipment is selected, (5) Storage/demurrage if your shipment sits at port, (6) FBA or 3PL receiving fees. These can add 3-8% to total landed cost.
