Amazon gives sellers access to hundreds of millions of buyers. But every sale comes with fees layered on top of fees — and unless you know what they are ahead of time, they can easily eat your margin down to almost nothing.
This guide covers the fees for selling as a third-party seller on Amazon (not Amazon Vendor Central, which is a separate program for brands selling wholesale to Amazon).
Step One: Individual vs. Professional Seller Plan
The first decision is which selling plan to use:
If you're selling more than 40 items a month, the Professional plan is cheaper than paying $0.99 per item. Most serious sellers use Professional from the start.
Referral Fees: Amazon's Cut of Every Sale
No matter which plan you're on, Amazon charges a referral fee on every item sold. This is a percentage of the total sale price (including shipping). The rate varies by product category:
FBA Fees: Fulfillment by Amazon
If you use Fulfillment by Amazon (FBA), Amazon picks, packs, and ships your orders from their warehouses. This is convenient but adds significant per-unit fees on top of the referral fee.
FBA also makes your products eligible for Amazon Prime — a significant conversion advantage. But you need high enough margins to absorb the fulfillment fees on top of everything else.
Hidden Costs That Catch Beginners Off Guard
- Sponsored Products ads: Amazon's search is pay-to-play for competitive categories. Advertising costs can range from a few cents to several dollars per click, and they add up fast.
- Returns: Amazon's return window is generous, and returned items often can't be resold as new. Plan for a return rate of 5–15% in many categories.
- Aged inventory: If your products sit unsold in FBA warehouses, you'll accumulate storage fees — and potentially long-term storage fees after a year.
- Closing fees: Some media categories (books, DVDs) have an additional variable closing fee of around $1.80 per item.
Example: What You Actually Keep from a $35 Sale
Let's say you're a Professional seller on a product in a category with a 15% referral fee, using FBA, selling for $35:
Sale price: $35.00 Referral fee (15%): $5.25 FBA fulfillment fee (small standard item): $3.75 Professional plan (at 100 sales/mo): $0.40/item Total fees: $9.40 If your product cost $10 to source, you keep: $35 – $10 – $9.40 = $15.60 That's a 44.6% margin — before advertising costs.
Add in even modest ad spend and your effective margin can drop to 25–30% or below. That's still workable, but it's important to know the real number before committing to a price.
Is Amazon Worth It for Beginners?
Amazon gives you immediate access to massive buyer traffic. You don't have to build an audience from scratch, and Prime eligibility via FBA can dramatically increase your conversion rate.
The challenge is that fee complexity is high, competition is intense, and the costs of advertising, returns, and storage can erode margins you thought you had. Amazon works best for sellers with:
- Products that have a clear cost of goods and enough margin to absorb 25–35% in total fees.
- Sufficient inventory to justify FBA storage, or a reliable fulfillment-by-merchant (FBM) operation.
- A product with differentiation — otherwise, you're competing on price alone, which rarely ends well.
Key Takeaways
- Choose Professional ($39.99/mo) if you plan to sell more than 40 items per month.
- Referral fees vary by category — typically 8–15%, sometimes higher for clothing.
- FBA adds $3–$6+ per unit in fulfillment fees, plus monthly storage costs.
- Budget for advertising — it's almost unavoidable in competitive niches.
- Total fees often land between 25–40% of your sale price on an FBA listing.
- Run your numbers at every price point before launching a new product.
