How to Calculate Landed Cost: The Complete Formula for Importers

What Is Landed Cost?

Landed cost is the total cost of getting a product from your supplier's factory to your warehouse or fulfillment center — everything included. It's the number that actually determines your margin, not the invoice price you paid your supplier.

Most ecommerce sellers underestimate landed cost by 20–40% because they only account for the product price and freight. They forget customs duties, the Merchandise Processing Fee, cargo insurance, drayage, and the Section 301 tariff overlay that can add 7.5% to 25% on top of the base rate for Chinese-origin goods.

If your landed cost model is wrong, your pricing is wrong. This guide gives you the complete formula.

The Landed Cost Formula

Landed cost has seven core components. Every importer needs to account for all of them:

The Full Formula

Landed Cost = Product Cost + Freight + Insurance + Customs Duties + Section 301/IEEPA Tariffs + MPF + HMF + Drayage + Broker Fee + Destination Charges

Section 301 and IEEPA: The Hidden Cost Multiplier

For importers sourcing from China, the Section 301 tariff overlay is frequently the largest single line item after the product cost itself. These tariffs — which range from 7.5% to 25% under Lists 1–4, and now up to 145% including IEEPA emergency tariffs — stack on top of the base MFN duty rate.

A product with a 3.7% base duty rate and a 25% Section 301 rate has a total effective tariff rate of 28.7%. If you're only modeling 3.7%, your landed cost is significantly understated.

See our guide to calculating import duties for the exact method to stack Section 301 rates on top of base MFN duties.

Landed Cost by Shipment Type

FCL (Full Container Load)

When you're shipping enough volume to fill a 20-foot or 40-foot container, you book FCL. Your per-unit freight cost is lower, but you bear all the fixed costs (ocean freight, customs entry, drayage) regardless of how full the container is. FCL makes sense when volume is high enough to spread those fixed costs thin.

LCL (Less than Container Load)

LCL consolidates your cargo with other shippers' goods in a shared container. You pay by cubic meter (CBM) or weight. LCL has higher per-unit freight costs than FCL, plus a consolidation/deconsolidation fee at each end. For small importers or first shipments, LCL is often the right starting point.

Air Freight

Air freight is 5–10x the cost of ocean freight per kilogram but delivers in 3–7 days vs. 20–45 days. For high-value, low-weight goods with tight lead times (or a stockout risk at Amazon FBA), air can be worth the premium. Always model the carrying cost of capital when comparing ocean vs. air timelines.

How to Build Your Landed Cost Model

Build a landed cost spreadsheet with one row per SKU and columns for each cost component. Here's the recommended structure:

• Column A: Product cost (FOB per unit)
• Column B: Freight cost per unit (total freight ÷ units per shipment)
• Column C: Insurance (0.75% × customs value per unit)
• Column D: Customs value per unit (Column A + C for FOB; A + B + C for CIF)
• Column E: Base duty (Column D × MFN duty rate from HTS)
• Column F: Section 301 / IEEPA tariff (Column D × applicable rate)
• Column G: MPF per unit (total MPF ÷ units per entry, capped at $614.35)
• Column H: HMF per unit (0.125% × Column D)
• Column I: Drayage + broker fee per unit
• Column J: Total landed cost = sum of all columns
• Column K: Landed cost as % of product cost = Column J ÷ Column A

Landed Cost Benchmarks by Product Category

As a rough sanity check, here's what total landed cost typically looks like as a percentage markup over FOB price:

How to Reduce Your Landed Cost

Once you have an accurate landed cost model, you can identify where the leverage is. Common reduction levers include:

• HTS reclassification: A lower duty rate on the correct code saves money on every future shipment. Use our free HTS lookup tool to verify your current codes.
• First sale valuation: If you buy through a middleman, you may be able to declare customs value at the factory price instead of the resale price. See our guide on the first sale rule.
• Consolidating entries: The MPF is capped at $614.35 per entry. Consolidating multiple SKUs into fewer entries maximizes the cap benefit.
• Diversifying sourcing country: Moving production out of China eliminates Section 301 and IEEPA exposure entirely — often the single largest savings available.
