Landed cost calculator

See what every unit on a purchase order really cost. Add the products, then freight, duty, and fees, and split the extra costs by value or by units.

Product	Invoice cost	Share of extras	Landed cost per unit

Splitting by value suits costs like duty, which grow with what the goods are worth. Splitting by units suits freight when your products are similar in size. Our landed cost guide walks through both. Posto does this on every purchase order, splits costs over what actually arrived, and can keep Shopify's cost per item up to date. See how Posto works.
