This free Amazon FBA profit calculator takes one product's cost, price and dimensions and returns the numbers that actually decide whether it's worth selling: landed cost per unit, Amazon's fulfilment and referral fees, net profit per sale and your margin. It runs entirely in your browser — nothing is saved and there's no login — so you can rework a product's economics as many times as you need.
Unit cost is what you pay your supplier per unit, before freight and duty. Retail price is your Amazon list price — the number buyers see. Dimensions and weight set the FBA fulfilment fee, because Amazon prices fulfilment by size tier and shipping weight; a package that crosses into the next size tier can quietly erase a chunk of margin. The calculator applies the current US fulfilment and referral fee schedules to those inputs, so the fee figures reflect what Amazon actually charges rather than a flat guess.
Use it before you source — to sanity-check that a product idea can carry Amazon's fees at a price the market will bear — and again before you place a purchase order, once you have real supplier quotes and carton dimensions. Those two moments are where a product's profitability is really decided; catching a thin margin here costs nothing, catching it after a production run is expensive.
The margin you see is only as honest as the landed cost behind it — unit cost plus freight, duty and per-unit handling, not just the supplier's quote. When you move from checking an idea to running a real order, the cartons-per-pallet calculator sizes the freight that feeds landed cost, and the full ManyMuse Launch supply-chain cockpit carries the same numbers through supplier specs, purchase orders and true landed cost — so the margin you decided on here is the margin you actually ship.
