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.
Margin after shipping
Subtracting shipping and packaging reveals the real margin a headline price hides. The calculation runs in your browser and never uploads your figures.
Frequently asked questions
What do the three numbers mean?
Sale price per unit, units sold, and your total shipping and item costs for those units. 100 units at $49 is $4,900 of revenue; minus $1,800 of costs leaves $3,100.
What is the Signal percentage?
Your margin: what is left after costs as a share of revenue. In the default example, $3,100 of $4,900 is a 63.3% margin.
What costs should I include?
Everything it takes to deliver the order: product cost, packaging, postage, and payment processing fees. Leaving any out makes a free-shipping offer look more profitable than it is.
