Frequently Asked Questions
What is Amazon's referral fee?▼
Amazon charges a referral fee of 8-15% depending on the product category. Most categories (Home, Toys, Sports, etc.) charge 15%. Consumer electronics are 8%, personal computers 6%, and some categories have minimum per-item fees of $0.30.
How are FBA fulfillment fees calculated?▼
FBA fees are based on product size tier and weight. Small standard items (≤15oz, ≤15x12x0.75in) start at $3.22. Large standard items start at $3.86. Oversize items start at $9.73. Additional per-pound fees apply for heavier items.
What are Amazon FBA storage fees?▼
Monthly storage fees are $0.87 per cubic foot from January-September and $2.40 per cubic foot from October-December (peak season). There are also aged inventory surcharges for items stored over 181 days.
Is FBA worth the fees?▼
For many sellers, yes. FBA provides Prime eligibility (higher sales velocity), handles shipping/returns, and builds buyer trust. Products typically sell 20-30% more units with FBA vs FBM. However, profitability depends on your margins.
How do I calculate my Amazon profit margin?▼
Profit = Sale Price - Referral Fee - FBA Fee - Storage Fee - Cost of Goods. For a $25 product (15% category) with $5 COGS and $3.86 FBA fee: $25 - $3.75 - $3.86 - $0.15 - $5.00 = $12.24 profit (49% margin).
What is the minimum profit margin for Amazon FBA?▼
Most successful FBA sellers target at least a 30% profit margin after all fees. Products with margins below 20% are risky because unexpected costs (returns, PPC advertising, price drops) can quickly eliminate profits.
