亚马逊FBA利润计算器

Amazon FBA (Fulfillment by Amazon) lets you store products in Amazon's warehouses while they handle shipping, returns, and customer service. But the fees add up quickly. Our free Amazon FBA calculator helps you understand exactly what you'll pay.

Tips for Amazon FBA Sellers

• Target 30%+ gross margin after all Amazon fees — below 20% is risky
• Avoid oversized items — FBA fees jump dramatically for products over 18" or 20 lbs
• Monitor storage fees — aged inventory surcharges can eat your margins during slow seasons
• Compare FBA vs FBM (Fulfillment by Merchant) — FBM saves fees but you lose Prime badge
