FBA typically costs more per unit in fees ($3-6+ fulfillment fee) but provides Prime eligibility, higher conversion rates, and hands-off logistics. FBM has lower per-unit costs but requires managing shipping, storage, and customer service yourself. FBA is generally more profitable for products under 5 lbs selling 10+ units/month.
FBA charges fulfillment fees ($3-6+ per unit), storage fees ($0.87-2.40/cu ft), and referral fees. FBM only charges referral fees but you pay for shipping, packaging, warehouse space, labor, and customer service staff separately.
FBA is typically more cost-effective for standard-size products under 5 lbs, items selling 10+ units/month (to avoid long-term storage fees), products benefiting from Prime eligibility, and sellers who value time over per-unit cost optimization.
Consider FBM for oversized/heavy items where FBA fees are prohibitive, slow-moving inventory (to avoid storage fees), products requiring special handling, items with very thin margins, or when you have existing warehouse infrastructure.
Prime-eligible listings typically see 20-30% higher conversion rates. With FBA, all products are automatically Prime-eligible. FBM sellers can earn Prime through Seller Fulfilled Prime (SFP), but the requirements are stringent and costly to maintain.
Yes, many sellers use a hybrid approach. Send your best-selling inventory to FBA for Prime eligibility while fulfilling slower-moving SKUs or oversized items via FBM. This optimizes both costs and customer experience.
Track every fee, calculate true profit per unit, and never guess your margins again.
