Amazon seller margin
Use this for early product research, listing planning, and rough FBA margin checks. Actual Amazon fees vary by category, size, weight, fulfillment method, return behavior, and seller account details.
Formula: sale price minus product cost, referral fee, fulfillment, storage, and ad cost
- Referral fee is usually category dependent.
- Fulfillment cost can represent FBA or self-fulfilled shipping.
- Ad cost per unit helps model PPC impact on margin.
