Complete breakdown of Amazon FBA fees in 2026 — referral fees, fulfillment fees, storage fees, and hidden costs. With real examples and a free margin calculator.
Amazon FBA Fees Explained: Every Cost You Need to Know in 2026
Most new sellers underestimate Amazon's cut. They run a quick margin calculation based on supplier price and selling price, decide the numbers look good, and place the order. Then the first month of sales arrives and the actual payout is 15–20% lower than expected. The reason is almost always fees that were not fully accounted for. This article lays out every cost with real numbers so you can build an accurate margin model before committing to inventory.
The 4 Main FBA Fees
1. Referral Fee
The referral fee is the percentage of your selling price that Amazon charges for connecting your listing to the buyer. It applies to every sale, regardless of whether you use FBA or fulfill yourself.
The rate depends on category, not product type. Most home goods pay 15%. Electronics pay as little as 8%. Clothing pays the highest rate.
| Category | Referral Fee Rate |
|---|---|
| Home & Kitchen | 15% |
| Clothing & Accessories | 17% |
| Electronics | 8% |
| Health & Personal Care | 8% |
| Grocery & Gourmet Food | 8% |
| Beauty | 8% |
| Toys & Games | 15% |
| Sports & Outdoors | 15% |
| Pet Supplies | 15% |
| Office Products | 15% |
Minimum referral fee: $0.30 per item. For very low-priced products, Amazon charges whichever is higher — the percentage or $0.30.
If you are selling a $29.99 Home & Kitchen product, the referral fee is $4.50 (15% of $29.99). That is a fixed cost on every unit sold, whether you run ads or not.
2. FBA Fulfillment Fee
The fulfillment fee covers Amazon picking, packing, shipping, and customer service for every order. It is calculated per unit based on the product's size tier and shipping weight.
Size tier definitions:
- Small Standard: Up to 15" x 12" x 0.75", up to 16 oz.
- Large Standard: Up to 18" x 14" x 8", up to 20 lbs.
- Large Bulky and beyond: Anything larger triggers significantly higher fees.
Most private label products land in the Large Standard tier. Here are the 2026 rates for standard-size items:
| Size Tier | Unit Weight | FBA Fee |
|---|---|---|
| Small Standard | 2 oz or less | $3.06 |
| Small Standard | 2+ to 4 oz | $3.15 |
| Small Standard | 4+ to 6 oz | $3.24 |
| Small Standard | 6+ to 8 oz | $3.33 |
| Small Standard | 8+ to 12 oz | $3.43 |
| Small Standard | 12+ to 16 oz | $3.53 |
| Large Standard | 4 oz or less | $3.68 |
| Large Standard | 4+ to 8 oz | $3.90 |
| Large Standard | 8+ to 12 oz | $4.15 |
| Large Standard | 12+ to 16 oz | $4.45 |
| Large Standard | 1+ to 1.5 lbs | $5.05 |
| Large Standard | 1.5+ to 2 lbs | $5.49 |
| Large Standard | 2+ to 3 lbs | $5.99 |
| Large Standard | 3+ to 20 lbs | $6.10 + $0.08/lb above 3 lbs |
A 12 oz Large Standard product — typical for a kitchen gadget or small home accessory — costs $4.45 per unit to fulfill. That number does not change based on your selling price. It is the same whether you sell at $19.99 or $49.99, which is why selling price is one of the most important levers in your margin model.
3. Monthly Inventory Storage Fee
Amazon charges you for the space your inventory occupies in their fulfillment centers. The rate is calculated per cubic foot per month and varies by season.
| Period | Storage Rate (per cubic foot/month) |
|---|---|
| January – September | $0.78 |
| October – December | $2.40 |
The Q4 rate is more than three times the standard rate. Sellers who over-order heading into Q4 and fail to sell through can see storage costs eat deeply into margins.
Example calculation:
A typical product with dimensions 10" x 6" x 3" has a volume of:
- 10 × 6 × 3 = 180 cubic inches
- 180 ÷ 1,728 (cubic inches per cubic foot) = 0.104 cubic feet
At the standard rate: 0.104 × $0.78 = $0.08 per unit per month
That is negligible for fast-moving inventory. At the Q4 rate, the same unit costs $0.25/month. The danger is slow-moving or stranded inventory sitting for multiple months — those costs compound.
4. Professional Seller Account Fee
A Professional Selling Plan costs $39.99 per month, flat. It gives you access to bulk listing tools, advertising, the Buy Box, and category approvals that Individual accounts cannot access.
The Individual plan has no monthly fee but charges $0.99 per item sold. The math is straightforward: if you plan to sell more than 40 units per month, the Professional plan costs less per unit and gives you substantially more capability.
For any serious product launch, start with Professional. The $39.99 is a fixed overhead cost that drops to negligible on a per-unit basis once you have meaningful sales volume.
Other Fees to Know
These fees do not apply to every seller every month, but ignoring them will cost you at some point:
- Long-term storage fee: Units stored for 365+ days are charged $6.90 per cubic foot or $0.15 per unit (whichever is greater), assessed monthly. Avoid this entirely with disciplined inventory management.
- Returns processing fee: When a customer returns an item in certain categories (like Apparel), Amazon charges you a returns processing fee equal to the original fulfillment fee. Budget a return rate of 3–8% depending on category.
- Removal order fee: If you want Amazon to send your inventory back to you or dispose of it, the fee is $0.97–$1.89 per standard-size unit depending on weight. Run removals before items hit 365-day storage thresholds.
- High-volume listing fee: $0.005 per eligible ASIN per month for sellers with more than 1.5 million non-media ASINs. This does not apply to most new sellers.
- Inbound placement service fee: When sending inventory to Amazon's fulfillment network, Amazon may charge a fee to distribute your units to multiple warehouses. Sending to a single location incurs a higher fee per unit; opting into Amazon's distributed placement reduces or eliminates it.
Real Example: Calculating Margin on a $29.99 Home Product
Here is a full fee walkthrough for a 12 oz Large Standard kitchen accessory selling at $29.99.
| Line Item | Amount |
|---|---|
| Selling Price | $29.99 |
| Referral Fee (15%) | -$4.50 |
| FBA Fulfillment Fee (12 oz Large Standard) | -$4.45 |
| Monthly Storage (0.1 cu ft, Jan–Sep) | -$0.08 |
| Product Cost (landed, including freight) | -$8.00 |
| Net Profit per Unit | $12.96 |
| Margin | 43% |
On paper, 43% looks healthy. But this calculation has not touched advertising yet.
A new listing with no reviews needs PPC to generate its first sales. A reasonable early-launch assumption for a competitive home product is $4–7 in ad spend per unit sold, depending on your ACoS and category competition. At $5 in PPC, that 43% margin drops to 26%. At $7, it drops to 20%.
This is why the 30% margin threshold matters — it is not a target for your pre-PPC margin, it is a floor. You need enough margin headroom so that after advertising costs settle to a sustainable level, you are still profitable.
The Margin Threshold Most Sellers Use
Target a minimum of 30% net margin after all fees, before PPC. That cushion absorbs:
- Early-launch PPC at higher-than-steady-state ACoS
- Return rates that vary by category
- Occasional storage surcharges
- Price adjustments to win the Buy Box during competitive periods
- Freight cost fluctuations
If your pre-PPC margin is below 25%, the product is difficult to make work unless you have exceptional organic ranking or very low return rates. Products below 20% pre-PPC are generally not worth launching as a first product — the margin for error is too thin.

From Margin to Margin Protection
Knowing your margin is viable is step one. Protecting that margin through the launch is where most sellers fall short.
The most common way new sellers erode margin in the first 60 days is poor keyword targeting and overspending on PPC before their listing has enough conversion data to optimize against. High bids on broad keywords with weak listing copy produce clicks that do not convert, and those sunk costs pull directly from your margin.
Launch Fast builds your keyword strategy and listing structure before you go live, so your listing is already optimized for conversion when your first PPC campaign starts. That means your initial ad spend converts at a higher rate from day one, which lowers your effective cost per unit sold and preserves more of the margin you calculated above.
