Is Amazon FBA worth it? The real fees, a worked example, and who it suits

Fulfilled by Amazon (FBA) sounds like a dream business: send your products to Amazon's warehouses, and Amazon stores them, ships them, handles returns and puts them in front of millions of shoppers. You just collect the money. Some people really have built big businesses this way. Many more have lost money on stock that never sold.

So is Amazon FBA worth it? Here are the real fees, a worked example of profit on one sale, the risks that catch beginners, and who it actually suits.

How Amazon FBA works

You buy products (often your own branded version of an existing product, called private label), ship them to Amazon's fulfilment centres, and list them on Amazon. When a customer orders, Amazon picks, packs, ships and handles customer service. You pay Amazon fees for selling and for fulfilment.

The fees you'll pay

Fee	What it is
Professional selling plan	$39.99 a month
Referral fee	A percentage of each sale, 15% in many categories
FBA fulfilment fee	Per unit, based on size, weight and price
Storage fees	Monthly, higher in the busy season and for slow stock
Advertising	Optional, but most new products need it

Amazon lists these on its selling pricing page. For 2026, Amazon kept referral fees unchanged and raised FBA fees by an average of $0.08 per unit, according to its 2026 fee update.

Is Amazon FBA worth it? The math on one sale

Here's an illustrative example of a small, light product selling for $25. Your real numbers will differ, but the shape is typical.

Item	Amount
Customer pays	$25.00
Product cost, including shipping to Amazon	minus $6.00
Referral fee (15%)	minus $3.75
FBA fulfilment fee (small standard item)	minus about $4.00
Storage and returns, per unit	minus about $0.75
Advertising cost per sale	minus $5.00
Profit per unit	About $5.50

That's a healthy product. Sell 300 a month and you'd make around $1,650 before the monthly plan and other costs. But notice how much depends on two lines you don't fully control: advertising cost and how fast the stock sells.

The risks that catch beginners

• Upfront inventory. You typically buy hundreds of units before selling one. If they don't sell, that money is stuck in a warehouse, paying storage fees.
• Competition and copycats. Successful products attract competitors, which pushes prices down and advertising costs up.
• Supplier problems. Quality issues, delays and defects become your reviews and returns.
• Account health. Amazon can suspend listings or accounts over complaints, policy issues or paperwork.
• Cash flow. Amazon pays out on a schedule while you're already paying for the next order of stock.

The "automation" trap

A whole industry sells "done for you" Amazon stores and automation programs. In September 2024, the FTC's Operation AI Comply included action against FBA Machine, a scheme that, according to the FTC, promised AI-powered online stores would earn passive income and took more than $15 million from consumers. If someone offers to run an Amazon store for you in exchange for a large upfront fee, walk away.

What makes a good first FBA product

• Small and light, so fulfilment and storage fees stay low.
• Not fragile, to avoid damage and returns.
• Steady demand all year, not a short fad or a single holiday.
• Room to improve on existing listings, based on what their negative reviews complain about.
• No heavy regulation, like supplements, children's products or electronics that need certification, until you have experience.

Who Amazon FBA suits

• People with several thousand dollars they can afford to risk.
• People who enjoy product research, sourcing and numbers.
• People willing to treat it as a business for a year or more before judging it.
• People with a product idea they understand better than competitors.

Lower-risk ways to start

If you're curious but cautious, start where you risk less: resell discounted branded items in small quantities, or learn selling skills with no inventory at all. Flipping secondhand items teaches pricing and product selection; see how to flip items on Facebook Marketplace. Digital products avoid inventory entirely; see how to sell digital products on Etsy. And if you want to earn from Amazon without selling at all, our next guide covers ways to make money with Amazon. Compare it with dropshipping, which avoids inventory but brings thinner margins.
