Shipping economics
Marketplace shipping cost guides
Check how buyer-paid shipping, seller-paid label cost, and marketplace fee treatment change payout before you decide whether to charge shipping or absorb it into the item price.
Shipping changes more than postage
A label cost is only one part of the shipping decision. Buyer-paid shipping can change fee base, seller-paid shipping can lower net payout, and free shipping can force a higher item price before the listing actually breaks even.
Use these platform pages to isolate fee treatment, then use the shipping calculator when packaging, insurance, signature confirmation, or multi-unit allocation changes the true label cost.
