Calculate gross margin, net margin, markup, and ROI on any product — then work backwards to the selling price that hits the margin you actually want.
The calculator opens with a typical private-label example. Replace every field with your own numbers — and use landed cost for the unit cost, not the supplier invoice price.

Your current price already clears that target.
Every figure is per unit unless labelled otherwise. Results update as you type.
Where the price goes
Monthly at 500 units
This margin is only as good as your unit cost.
SupplyAutomate tracks the real cost of every purchase order — supplier price, freight, duty, and prep — so the margin you model here matches the one you actually earn.
The four numbers
Margin and markup describe the same profit against different denominators, and mixing them up is the most expensive arithmetic error in ecommerce pricing. A product costing $8.40 sold at $24.99 carries a 66.4% gross margin but a 197.5% markup. Price to the markup figure when you meant the margin and you will land well under the number you planned for.
Selling price minus the unit cost of the product, as a percentage of the price. Measures the product itself.
The same calculation after shipping, payment fees, and overhead. Measures the business.
Profit over cost rather than over price. Always a bigger number than margin, and easy to confuse with it.
Work backwards: name the margin you want and get the price that delivers it after fees.
Selling on Amazon or a Shopify store?
Referral fees, fulfilment fees, and ad spend change the picture enough to deserve their own tools. Use the Amazon profit calculator for FBA, or the dropshipping profit calculator for a DTC store. To get the unit cost right in the first place, start with the landed cost calculator or the import duty calculator.
The calculator is free. The margin is the hard part.
Every number above depends on what your unit truly costs delivered. SupplyAutomate reads your invoices, files them against the right order, and keeps that cost current as freight and duty land — so the margin you priced against is the margin you get.
