Landed Cost Calculator

Supplier price alone is not the cost base you sell against. This calculator adds inbound shipping, customs duty, and other import overhead so you can see the true landed cost and the selling price needed to preserve target margin.

Calculate landed cost

Enter supplier cost, inbound shipping, duty rate, and any extra import overhead per unit. The result shows the true landed cost and the selling price needed to maintain the margin you want after the goods arrive.

Quick landed cost scenarios.

Formula

What landed cost really means

Landed cost = Supplier cost + Inbound shipping + Duty + Other import cost

Required selling price = Landed cost / (1 - Target margin / 100)

If you price from supplier cost alone, every inbound and customs layer quietly steals margin later. Landed cost pulls those layers forward so the price floor is realistic before the product starts selling.

Common mistakes

Ignoring inbound freight because it arrives in a different invoice.
Leaving duty out of the unit economics until margin already looks weak.
Using a target markup without understanding the implied margin.

Useful next step

Once landed cost is clean, use break-even ROAS and fee tools to see whether the product still has enough contribution left for traffic and platform drag.
