How Amazon Fees Affect Your Real Profit
Amazon takes a cut at every stage. Here is exactly what you pay and how each fee chips away at your bottom line.
The Fee Stack Every Seller Faces
Amazon does not charge a single, simple commission. Instead, fees come from multiple sources and vary by category, product size, time of year, and fulfillment method. Understanding each layer is critical because together they can consume 30–45% of your selling price before you even account for your own product costs.
Fee Types at a Glance
| Fee Type | How Calculated | Example on a $29.99 Item |
|---|---|---|
| Referral Fee | % of total sale price; rate set by product category | $4.50 (15% — Home & Kitchen) |
| FBA Fulfillment Fee | Fixed per-unit rate based on size tier and shipping weight | $4.25 (large standard, ~12 oz) |
| Monthly Storage Fee | Per cubic foot charged on the 15th of each month | ~$0.22 / month (0.25 cu ft, off-peak) |
| Aged Inventory Surcharge | Extra per-cubic-foot charge once inventory exceeds 181 days in FBA | $0.50+ per cu ft (181–210 days) |
| Return Processing Fee | Approximately equal to the original fulfillment fee; applies in free-returns categories (clothing, shoes, jewelry) | ~$4.25 per returned unit |
| Inbound Placement Fee | Per-unit charge if you ship to a single FC instead of Amazon distributed locations | $0.27 – $1.58 per unit |
| Removal / Disposal Fee | Per-unit fee to retrieve or discard unsold FBA inventory | $0.97 per standard-size unit |
| Unplanned Service Fee | Per-unit charge when Amazon corrects missing labels or prep on arrival | $0.55 labeling; $1.00+ bagging |
Referral Fees by Category
The referral fee is a percentage of the total sale price (including shipping charged to the customer). Amazon applies this to every item sold, regardless of whether you use FBA or fulfill orders yourself. The most common rates:
- Most categories (Home, Kitchen, Sports, Toys, etc.): 15%
- Clothing and Accessories: 17%
- Electronics: 8%
- Personal Computers: 6%
- Grocery and Gourmet Food: 8% for items over $15, 15% for items $15 and under
- Jewelry: 20% on the first $250, 5% on anything above
- Amazon Device Accessories: 45%
For a $25 product in a 15% category, the referral fee alone is $3.75. That is money off the top before any other cost is considered.
FBA Fulfillment Fees
If you use Fulfillment by Amazon, you pay a per-unit fee every time an order ships. Amazon determines the fee based on the item's size tier and shipping weight.
Standard-Size Items
- Small standard (6 oz or less): ~$3.06
- Small standard (6–16 oz): ~$3.22
- Large standard (6 oz or less): ~$3.68
- Large standard (6–16 oz): ~$4.25
- Large standard (1–2 lb): ~$5.40
- Large standard (2–3 lb): ~$6.10
Oversize Items
- Small oversize (70 lb or less): ~$9.73 + $0.42/lb above first 2 lb
- Medium oversize: ~$19.05 + $0.42/lb above first 2 lb
- Large oversize: ~$89.98 + $0.83/lb above first 90 lb
These fees add up fast. A 1.5 lb product at $5.40 per unit in FBA fees means Amazon takes over 20% of a $25 selling price just for fulfillment.
Monthly Storage Fees
Amazon charges for every cubic foot of warehouse space your inventory occupies, measured on the 15th of each month.
- January – September (standard size): $0.87 per cubic foot
- October – December (standard size): $2.40 per cubic foot
- January – September (oversize): $0.56 per cubic foot
- October – December (oversize): $1.40 per cubic foot
A product that takes up 0.25 cubic feet costs about $0.22/month in storage during off-peak. But send in 2,000 units and let 500 sit through Q4, and you are paying $300+ in storage for those slow movers during the most expensive quarter.
Aged Inventory Surcharge
If inventory has been in Amazon's warehouses for more than 181 days, you face an additional surcharge. For items aged 181–210 days, the surcharge is approximately $0.50 per cubic foot on top of regular storage. Items sitting beyond 271 days can incur surcharges of $1.50 per cubic foot or more. At 365+ days, the penalties increase further. This is designed to discourage sellers from using Amazon as cheap long-term warehousing.
Other Fees That Catch Sellers Off Guard
Return Processing Fee
In categories with free customer returns (clothing, shoes, jewelry), Amazon charges you a return processing fee roughly equal to the original fulfillment fee. If 8% of your clothing items get returned, you are paying double fulfillment on those units.
Removal and Disposal Fees
If you need to pull inventory out of FBA, Amazon charges $0.97 per standard-size unit for removal and $0.34 per unit for disposal. If you have 500 units of a failed product, getting them shipped back costs nearly $500.
Unplanned Service Fees
If your products arrive at Amazon without proper labeling or preparation, Amazon will do it for you and charge $0.55 per unit for labeling and $1.00+ per unit for bagging or bubble wrapping. These add up quickly on large shipments.
FBA Inbound Placement Service Fee
Amazon may charge an inbound placement fee if you want your inventory sent to a single fulfillment center instead of being distributed across multiple locations. This fee varies by size and weight but can add $0.27–$1.58 per unit for standard-size items.
Putting It All Together: Example
Selling a $24.99 kitchen item in the 15% referral category:
- Referral fee: $3.75 (15%)
- FBA fee: $4.25 (large standard, 12 oz)
- Storage: $0.18 per unit/month
Amazon's total take: $8.18, which is 32.7% of your selling price before you pay for the product itself, shipping, or advertising.
If your COGS is $5.00, inbound shipping is $1.00, and advertising is $2.50 per unit, your remaining profit is $8.31 per unit or a 33.3% net margin. Change the referral fee to 17% (clothing) and the margin drops to 31.3%. Move to an oversize product and the FBA fee alone can erase half your margin.
How to Protect Your Margins
- Know your fees before sourcing. Run the numbers at the product research stage, not after you have 1,000 units in a warehouse.
- Optimize product size and weight. Shaving half an inch off packaging dimensions can drop you into a cheaper size tier and save $1–2 per unit.
- Manage inventory velocity. Send smaller, more frequent shipments to avoid aged inventory surcharges.
- Watch for fee changes. Amazon updates its fee schedule at least once a year, typically in January. Recalculate your margins whenever changes are announced.
