Understanding Amazon FBA Fees
Referral Fees
Amazon charges a percentage of each sale based on product category. Most categories are 15%, but some like electronics (8%) and jewelry (20%) vary. There's also a minimum fee of $0.30 per item.
FBA Fulfillment Fees
These cover picking, packing, shipping, and customer service. Fees are based on size tier (small standard, large standard, small oversize, etc.) and weight. Lighter, smaller items have lower fees.
Storage Fees
Monthly storage fees are calculated per cubic foot. Standard-size items cost $0.87/cu ft (Jan-Sep) or $2.40/cu ft (Oct-Dec peak season). Oversize items have lower rates.
Size Tiers Explained
Small Standard: ≤15" × 12" × 0.75", ≤16 oz
Large Standard: ≤18" × 14" × 8", ≤20 lb
Small Oversize: ≤60" × 30", ≤70 lb
Large Oversize: Anything bigger
Tips to Maximize FBA Profits
Optimize Product Size
Design packaging to fit within small standard tier when possible. A product at 15.1" pays significantly more than one at 14.9".
Manage Inventory Wisely
Avoid long-term storage fees by maintaining 2-3 months of inventory. Use Amazon's Inventory Performance Index to optimize.
Target 30%+ Margins
After all fees, aim for at least 30% profit margin. This provides buffer for PPC advertising, returns, and unexpected costs.
