What is landed cost?

Your $20 tee would like a word.

Landed cost is the full cost of getting one unit into your warehouse: the factory price (FOB), plus freight, plus import duty and any added tariffs. Price from landed cost, not from the factory quote.

The formula

landed cost = FOB + freight per unit + (FOB × duty %) + (FOB × added tariff %)

Worked example

A cotton knit tee, made abroad, sold in the US at $40:

Factory price (FOB)$20.00
Ocean freight, per unit$1.60
US duty, 16.5% of $20$3.30
Landed cost$24.90

Sold at $40, that's a 38% margin, not the 50% you get from the factory price alone. Fees and discounts take it lower again.

Common mistakes

Questions

Is landed cost the same as COGS?
Close, but not quite. Landed cost is per unit, before you sell anything. Cost of goods sold (COGS) is the landed cost of the units you actually sold in a period.
Does landed cost include shipping to customers?
No. Shipping to customers is a selling cost. Landed cost stops at your warehouse door.
How do I find my duty rate?
Find your product's HTS code and its duty rate, then confirm it with a licensed customs broker. OptiSKU suggests a likely code for 111 products as a starting point.
