Amazon FBA fees explained: every fee broken down for 2026
Amazon FBA fees are the #1 reason new sellers overestimate their margins. Understanding the complete FBA fee structure for 2026, including hidden fees most Amazon seller guides skip, is essential before you source your first product. Most people account for the referral fee and fulfillment fee, then get surprised by storage fees, long-term storage surcharges, removal fees, and return processing. Here's every Amazon FBA fee broken down, what it actually costs, and how to calculate your real profit per unit.
- Short answer: Amazon FBA fees typically consume 30-35% of your selling price on a standard-size product.
- The three main fees: referral fees (8-17%, usually 15%), fulfillment fees ($3.22 to $150+ by size and weight), and monthly storage ($0.87/cu ft standard, $2.40 in Q4).
- The silent killer: inventory over 181 days gets a long-term storage surcharge of $6.90/cu ft or $0.15/unit, whichever is greater. Start with 300-500 units.
- Bottom line: always calculate true net margin per unit before sourcing; the referral and fulfillment fees are unavoidable, storage fees are not.
The five fee categories
1. Referral fee (Amazon's commission)
Amazon charges a percentage of every sale as their commission for access to 300+ million active buyers. The rate depends on your product category:
| Category | Referral fee |
|---|---|
| Most categories (home, kitchen, toys, beauty, etc.) | 15% |
| Clothing & accessories | 17% |
| Electronics | 8% |
| Grocery & gourmet | 8-15% |
| Jewelry | 20% (first $250), 5% (above) |
| Amazon device accessories | 45% |
On a $25 product in the Home category, the referral fee is $3.75.
2. FBA fulfillment fee (pick, pack, ship)
This is what you pay Amazon to store, pack, and ship your product to the customer. It depends on size and weight:
| Size tier | Weight | Fulfillment fee |
|---|---|---|
| Small standard | 6 oz or less | $3.06 |
| Small standard | 6-12 oz | $3.15 |
| Large standard | 12 oz - 1.5 lb | $4.47 |
| Large standard | 1.5 - 3 lb | $5.44 |
| Small oversize | up to 70 lb | $9.73 + $0.42/lb above 1st lb |
| Large oversize | up to 150 lb | $89.98 + $0.83/lb above 90 lb |
Rates are approximate 2025/2026 figures. Amazon adjusts annually, check Seller Central for current rates.
3. Monthly storage fees
Amazon charges for warehouse space by the cubic foot:
- January-September: $0.87 per cubic foot, per Amazon's FBA monthly storage fee schedule in Seller Central
- October-December: $2.40 per cubic foot (Q4 premium, Amazon needs the space)
A product measuring 10"×8"×4" takes 0.185 cubic feet. Monthly cost: $0.16 in normal months, $0.44 in Q4. Seems trivial, until you have 2,000 units sitting for 4 months.
4. Long-term storage fees (the silent killer)
Amazon's 10-K filings show warehouse and fulfillment costs as one of its largest operating expense lines, which is why inventory sitting in Amazon's warehouse for over 181 days gets hit with a surcharge of $6.90 per cubic foot or $0.15 per unit (whichever is greater), charged monthly. Inventory over 365 days is even worse.
This is the fee that destroys new sellers who overorder. If you send 2,000 units and only sell 500 in 6 months, the remaining 1,500 start accumulating surcharges that eat your entire margin.
New sellers often order 1,000+ units to get a lower per-unit cost from their supplier, then can't sell through fast enough. The long-term storage fees wipe out the manufacturing savings. Start with 300-500 units. Reorder when you have 30 days of inventory left.
5. Other fees most sellers forget
- Return processing fee: Equal to the fulfillment fee. If a customer returns your $25 product, you lose ~$3.50 in fulfillment + the return processing fee + potentially a damaged/unsellable unit.
- Removal/disposal fee: $0.97-1.04 per unit to get unsold inventory shipped back to you, or $0.32-0.39 to have Amazon destroy it.
- Inbound placement fee: Introduced 2024, Amazon may charge $0.21-1.58 per unit if you don't split shipments across multiple fulfillment centers.
- Labeling fee: $0.55 per unit if Amazon applies FNSKU labels for you.
- Prep service fee: $1.00-2.20 per unit if Amazon bags, wraps, or preps your items.
Real example: true profit on a $25 product
| Line item | Amount |
|---|---|
| Selling price | $25.00 |
| Referral fee (15%) | −$3.75 |
| FBA fulfillment (12 oz item) | −$3.15 |
| Monthly storage (avg) | −$0.20 |
| Product cost (landed from China) | −$4.50 |
| PPC advertising (~15% of revenue) | −$3.75 |
| Photography/listing (amortized) | −$0.30 |
| Net profit | $9.35 (37.4%) |
That's a healthy margin. But if your product costs $8 landed instead of $4.50, or your PPC is 25% instead of 15%, profit drops to $3-4 per unit. Always run the numbers before sourcing. Our step-by-step FBA profit calculator guide walks through the math on a real product.
