More than postage. Your true fulfillment cost includes the carrier or postage charge, packaging materials (box, mailer, tape, filler, labels), and the labor time to pick, pack, and dispatch. Add them up and the real number is often well above the postage alone — which is why some sellers quietly lose money on 'free shipping'.
Only if the cost is built into your price. 'Free' shipping isn't free — you absorb the full fulfillment cost, so your product margin must cover it. This calculator shows your true per-order cost so you can decide whether to charge for shipping, raise prices to bake it in, or set a free-shipping threshold that protects your margin.
A ready-to-use spreadsheet (Excel & Google Sheets): true per-order shipping cost from postage, packaging, and labor, net profit or loss on shipping, and option comparisons — delivered instantly after checkout. AI-assisted, human-built; not financial advice.
