Free Amazon Profit Margin Calculator

Three steps.
Zero friction.
- 01
Enter your selling price and unit cost (COGS landed in your warehouse).
- 02
Add the FBA fulfillment fee (use our FBA calculator if unknown) and category referral % (8-15%).
- 03
Add average PPC spend per unit and units sold per month for a monthly profit estimate.
The four numbers that decide whether your Amazon product survives
Most Amazon sellers know their COGS and referral fee, but underestimate FBA fulfillment and PPC spend per unit. Both compound: as you raise rank with ads, PPC eats your margin until organic sales catch up.
A healthy private-label product nets 20-30% margin after all four costs. Below 15% per unit you can't afford ads, returns, or a reorder cycle. This calculator runs the math so you can pressure-test pricing before launch — or decide whether to raise price now.
