What Is Net Profit for Amazon FBA / FBM Sellers?
Net profit is selling price minus every cost: COGS, first-mile shipping, Amazon referral commission, fulfillment fee, advertising, tariff, prep, and refund losses. This is the number that actually lands in your pocket.
Hidden Costs Amazon Sellers Often Overlook
- Referral commission (varies by category, typically 8%–15%)
- FBA fulfillment fee vs FBM shipping
- Refund and return loss
- Import tariff / duty
- PPC ad spend
- Prep / labeling cost
What Is a Good Profit Margin & ROI on Amazon?
Net margins under 5% are risky. 5%–15% is healthy for most Amazon stores, and above 15% is excellent. ROI tells you how efficiently your capital is working — aim to understand both, not just margin.
FBA vs FBM Profitability
FBA often wins on conversion (Prime badge) but carries fulfillment fees and storage risk. FBM saves fees but you handle shipping and returns. Use the mode toggle to compare both scenarios manually.
Break-Even Price & ACoS Ceiling
Break-even price is the minimum selling price to cover all costs. Max acceptable ACoS is the ad-spend-to-sales ratio at which you stop losing money. Use these for product sourcing and ad decisions.
Common Mistakes When Calculating Amazon Profit
- Forgetting referral fees vary by category
- Ignoring refund rate
- Using gross margin instead of net
- Not accounting for tariff and prep
