Landed Cost Calculator
See what one unit actually costs after product, freight, and duty — before you place the PO. A $12 factory price on 500 units with $840 freight and 7.5% duty lands at $14.58, not $12.

One shipment is a calculation. Fifty is a spreadsheet problem.
SupplyAutomate keeps the real landed cost of every purchase order up to date as supplier costs, freight invoices, and duty land, so you are not rebuilding this by hand each time.
What landed cost actually is
Landed cost is every inbound charge that makes one unit sellable, divided by the units you can sell — not the factory price, and not the PO quantity if some of the lot is unsellable. The calculator above is the three-line version you can run before a PO: product, freight, duty. The full method, including Incoterms and sellable-unit math, is in how to calculate landed cost.
The formula this page uses
(product × qty + freight + duty on product) ÷ qty
Example: 500 × $12 = $6,000 product. 7.5% duty = $450. $840 freight. Total $7,290 ÷ 500 = $14.58 per unit. Freight is $1.68 each. If you only shipped 100 units, that same $840 freight becomes $8.40 each.
Why calculating it accurately matters
Price off the real unit, not the invoice
A $12 factory quote that lands at $14.58 is a different product. If you advertised from $12, the freight invoice is where the margin went.
Compare suppliers on the same basis
A cheaper EXW quote can lose to a dearer FOB quote once pickup, freight, and duty are in the same column.
See what a small PO actually costs
Fixed freight and entry fees do not shrink with quantity. 100 units can carry five times the freight per unit of a 500-unit lot.
Leave room before you commit
Duty, fuel, and destination charges move after the PO. Knowing cost per unit early is what lets you walk away or reprice.
Landed cost calculator FAQ
The calculation is free. Keeping it true is the work.
Your landed cost changes after you order.
Freight gets rebilled, duty differs from the estimate, and the supplier revises the invoice. SupplyAutomate keeps purchase orders, suppliers, documents, freight, and duty in one workspace, so the cost per unit above stays accurate through the whole order instead of going stale the day you export it.
