Shipping Margin Calculator
Calculate rough product margin after shipping and packaging.
Margin after shipping and packaging
A product looks profitable until shipping and packaging quietly eat the margin. This calculator works out your rough margin after those costs, so you price with the true cost of fulfillment in view rather than just the product cost.
Seeing the real number prevents the classic e-commerce trap of selling at a loss on “free shipping.” Enter the price, product cost, and shipping and packaging, and get the margin — adjust the price or find cheaper fulfillment from there.
Private and instant
Everything runs locally in your browser using standard web APIs — nothing is uploaded, logged, or stored on any server — so the tool works offline, responds instantly, and keeps whatever you paste in on your own device. That makes it safe to use even for confidential, client, or internal data you would never send to an unknown website.
