How to read your FBA numbers
- Referral fee — Amazon's commission, usually ~15% of the sale price (varies by category).
- FBA fulfilment fee — the per-unit pick/pack/ship cost based on size and weight.
- Margin = profit ÷ selling price; ROI = profit ÷ product cost — both matter when sourcing.
Amazon referral and FBA fees vary by category, size and weight, and change over time. Use this as an estimate and confirm current fees in Seller Central.
