Calculate all Amazon seller fees including referral, FBA, storage, and closing fees. See true profit margin. Free Amazon fee calculator.
Amazon's fee structure is one of the most complex in e-commerce — referral fees, FBA fees, monthly storage fees, aged inventory fees, closing fees for media, and advertising costs all layer on top of each other. Most Amazon sellers underestimate total fees by 20-30%. Our calculator includes every fee category so you know your true margin before listing a product.
Complete Amazon fee structure: Selling plan: Individual $0.99/unit sold or Professional $39.99/month. Referral fee: 8-15% of selling price by category — most categories 15%. FBA fulfillment fee: $3.22-$6.00+ based on size and weight. Monthly storage: $0.78/cubic foot standard, $2.40 Oct-Dec peak. Aged inventory surcharge: after 181 days surcharges begin. Returns processing fee: $2.20-$5.40 per unit. Closing fee: $1.80 for media items.
Fulfillment method cost comparison on a $25 product: FBA: $3.75 referral (15%) + $4.50 fulfillment fee = $8.25 total Amazon fees. Net after fees: $16.75 before product cost. FBM (Fulfilled by Merchant): $3.75 referral (15%) only in Amazon fees. But you pay shipping ($4-$8 typically). Net after fees and shipping: $13.25-$17.25. FBA is often cost-competitive with FBM when you factor in labor to pack and ship. FBA wins on Buy Box eligibility and Prime badge.
Amazon total fee percentage varies by product type: Standard-size product sold via FBA: total fees 25-45% of selling price. Referral fee alone: 8-15% by category. Most categories are 15%. FBA adds another $3-$8 per unit in fulfillment fees. On a $20 product in most categories: expect $7-$10 in total Amazon fees (35-50% of price). This is why Amazon products need high gross margins before listing.
Storage fee management strategies: Maintain IPI score above 450 to avoid storage limits. Review aged inventory monthly — liquidate or remove units approaching 181 days. Use Amazon's removal or disposal service for slow-moving inventory before surcharges hit. Optimize reorder quantities — 6-8 weeks of inventory balances stockout risk and storage costs. Stranded inventory creates fees without sales — review regularly in Seller Central.
Yes for the right products. Amazon remains the largest e-commerce marketplace with 300+ million customers. Worth it when: product has 30%+ net margin after all fees, you can differentiate from existing listings, private label with strong branding. Avoid when: commodity product with many competing listings, thin margin under 20%, product prone to high returns, or heavy regulation category. Most successful Amazon sellers also sell on their own website to reduce platform dependency.
