Amazon FBA Cost Guide
Most new Amazon sellers dramatically underestimate what FBA actually costs. Fees typically eat 30–45% of the selling price across at least eight different categories. This guide breaks down every one in 2026 so you know your real cost before you buy inventory.
The Amazon FBA fee landscape
Amazon FBA fees fall into a few buckets: account fees ($39.99/month Professional plan), per-sale fees (referral and fulfillment), monthly storage, conditional fees (placement, returns, low-inventory, fuel surcharge), and your own costs (COGS, freight, ads, software). Together they usually consume 30–45% of the selling price.
Referral fees
Amazon's commission on every sale. Most categories are 15% (range 8–45%), calculated on the total sale price including any shipping you charge. Most categories carry a $0.30 minimum. Referral rates were unchanged for 2026.
Fulfillment fees
Per-unit pick, pack, ship, and customer-service fee based on size tier and weight, not price. Small standard items run roughly $3.06–$3.50; large standard $3.70–$11+; oversize $8.70 up to $75+. Fees rose about $0.08 per unit on January 15, 2026, and a 3.5% fuel surcharge applies from April 17, 2026. Products under $10 qualify for Low-Price FBA rates that average $0.86 less.
Storage and long-term storage fees
Monthly storage runs about $0.78/cu ft for standard items January–September and roughly $2.40/cu ft October–December. Aged-inventory surcharges start at 181 days and escalate sharply with age — the single biggest hidden killer of FBA profitability.
Conditional fees you can't ignore
Inbound placement ($0.21–$1.58 per unit, often avoidable with optimized splits), returns processing on high-return categories, Low Inventory Level fee (threshold raised to 35 days of supply in January 2026), and removal/disposal fees. Stacked together they can add $0.30–$4 per unit.
Advertising and software
Sponsored Products PPC is paid per click and measured by ACoS (ad spend ÷ ad revenue); most sellers target 15–30%, higher at launch. Research suites like Helium 10 or Jungle Scout run roughly $30–$300+ per month.
Worked examples: $10, $25, $50, $100
$10 product: ~$4.86 Amazon fees (48.6%), $3 COGS, ~15% ads → about $0.64 net profit (6.4%).
$25 product: ~$8.04 fees (32.2%), healthy net margin near 29% after ads — the classic FBA sweet spot.
$50 product: ~$13.44 fees (26.9%), net margin around 34%.
$100 product: ~$23.20 fees (23.2%), net margin near 37%.
The pricing rule that follows
Because the fulfillment fee is roughly a fixed dollar amount, it eats a much bigger percentage of cheap products. Target $20–$70 price points and aim for 25–35% net margin after every fee and ad cost. Always run the full fee waterfall before sourcing — guessing is what makes inventory unprofitable.
Frequently asked questions
- How much does Amazon FBA cost in total?
- Typically 30–45% of the selling price once you add referral (~15%), fulfillment ($3–$12+), storage, and conditional fees. Your COGS, ads, and software sit on top of that.
- What is the 2026 Amazon fuel surcharge?
- A 3.5% surcharge on the FBA fulfillment fee that took effect April 17, 2026 — about $0.17 per unit on average.
- What is Low-Price FBA?
- Products priced under $10 automatically receive lower fulfillment rates averaging $0.86 less than standard, helping budget items remain viable.
