Frequently asked questions

How much does Amazon FBA take per sale?

Typically the 15% referral fee plus a fulfillment fee of roughly $3–$7 for standard-size items. On a $30 product that's about $4.50 referral + ~$5.40 fulfillment ≈ $10 in Amazon fees before your product and shipping costs — which is exactly what this calculator nets out.

What's a good ROI / margin on Amazon FBA?

Many FBA sellers target a net margin of 15–30% and an ROI of 50–100%+ on product cost. Thin margins get wiped out by PPC and returns, so check break-even before you launch.

How do I get my exact FBA fulfillment fee?

Look up your product (or a similar ASIN) in Amazon's FBA revenue calculator, or check the fee preview in Seller Central — then type that number into the field above for a precise result.
