Amazon FBA Fees Breakdown: What You Actually Pay to Sell on Amazon
Complete guide to Amazon FBA fees including referral fees, fulfillment fees, storage fees, and hidden costs that eat into your margins.
What Is Amazon FBA?
Fulfillment by Amazon (FBA) means you send your inventory to Amazon’s warehouses, and they handle storage, packing, shipping, and customer service. In exchange, Amazon charges several layers of fees that every seller must understand before committing to the program.
The Core Amazon FBA Fees
1. Referral Fee
Amazon charges a referral fee on every sale, calculated as a percentage of the total price (item + shipping). The rate depends on the product category:
- Most categories: 15%
- Clothing & Accessories: 17%
- Electronics: 8%
- Grocery: 8-15%
- Jewelry: 20% (on items up to $250)
- Media (books, DVDs): 15%
There is also a minimum referral fee of $0.30 per item in most categories.
2. FBA Fulfillment Fee
This per-unit fee covers picking, packing, and shipping your order. It is based on the item’s size tier and weight:
| Size Tier | Weight | Approx. Fee |
|---|---|---|
| Small standard | Up to 12 oz | $3.22 |
| Large standard | Up to 1 lb | $3.86 |
| Large standard | 1-2 lb | $4.08 - $5.16 |
| Small oversize | Up to 2 lb | $9.73 |
| Large oversize | Up to 90 lb | $89.98+ |
These fees change annually, so always verify current rates in Seller Central.
3. Monthly Storage Fee
Amazon charges for warehouse space based on cubic feet:
- January - September: $0.87 per cubic foot
- October - December: $2.40 per cubic foot (peak season surcharge)
Slow-moving inventory gets hit hardest. If your product sits for over 181 days, you face aged inventory surcharges that can reach $6.90 per cubic foot or more.
4. Selling Plan Fee
- Individual plan: $0.99 per item sold (no monthly subscription)
- Professional plan: $39.99/month (unlimited listings)
If you sell more than 40 items per month, the Professional plan is cheaper.
Example: True Cost of Selling a $25 Product
Suppose you sell a small kitchen gadget for $25 that weighs 10 ounces:
| Fee Type | Amount |
|---|---|
| Referral fee (15%) | $3.75 |
| FBA fulfillment | $3.22 |
| Monthly storage (est.) | $0.15 |
| Total Amazon fees | $7.12 |
That is 28.5% of your selling price going to Amazon. Your landed product cost, shipping to Amazon, and any advertising spend come on top of that.
Fees Most Sellers Forget About
- Inbound placement fee: Amazon may charge to distribute your inventory across multiple warehouses
- Removal/disposal fees: Getting unsold inventory back costs $0.97+ per unit
- Return processing fee: For categories with free returns, Amazon charges a return processing fee equal to the fulfillment fee
- Labeling fee: $0.55 per unit if Amazon labels your products for you
- FBA prep fee: $0.70+ per unit if Amazon preps (bagging, bubble wrapping) your items
FBA vs. FBM: When to Fulfill Yourself
Fulfillment by Merchant (FBM) eliminates FBA fulfillment and storage fees, but you lose the Prime badge, which significantly impacts conversion rates. FBM makes more sense when:
- Your items are oversized and FBA fees are disproportionately high
- You sell slow-moving inventory that would rack up storage fees
- You have your own efficient fulfillment operation
- Your margins are too thin to absorb FBA costs
How to Reduce Your Amazon FBA Costs
- Optimize packaging — Smaller, lighter packaging means a lower size tier and lower fulfillment fees
- Monitor inventory health — Remove slow sellers before aged inventory surcharges kick in
- Ship during non-peak — Storage fees from October to December are nearly three times higher
- Use Amazon’s Revenue Calculator — Model your fees before sourcing any product
- Negotiate inbound shipping — Use Amazon’s partnered carrier rates or consolidate shipments to reduce per-unit inbound costs
