Amazon FBA Profit Calculator
Every cost, including the ones sellers forget.
Amazon revises fee schedules at least annually and adds new surcharges more often. These defaults are a starting point — the figures in your own fee preview are the ones that describe your ASINs.
Net profit per unit

Advertising is 11.3% of the price here — for most sellers it is the second-largest line after the product itself, and the one most often left out of a first profitability check.
How the Amazon FBA Profit Calculator works
Most first profitability checks include the product cost and the two headline fees, and stop there. Advertising, inbound shipping, storage and the cost of returns are what turn an apparently healthy 25% into single digits — and they are all knowable before you order.
Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price — check the platform's current fee schedule before you price a product against it. This is not tax or business advice.
Frequently asked questions
What margin should an FBA product make?
Sellers commonly target 15% to 25% net after all fees and advertising. Below 10% there is not enough room to absorb a fee increase or a bad quarter, and Amazon raises fees most years.
Why include advertising in unit economics?
Because on Amazon it is not optional. A new listing with no rank sells almost nothing organically, and even established products spend to defend position. Treating it as marketing overhead rather than a unit cost is how sellers convince themselves a losing product works.
What does a return actually cost?
The fulfilment fee again, the return shipping, the labour to inspect, and often the unit itself if it comes back unsellable. In apparel a 30% return rate can consume the entire margin.
What is left out of most calculators?
Inbound freight to the fulfilment centre, prep, aged inventory surcharges, removals for stock that never sold, and the capital cost of holding three months of inventory before Amazon pays you.
