Amazon takes a referral fee (commonly ~15%) plus an FBA fulfillment fee and monthly storage. After product cost, inbound shipping, returns, and advertising, the profit that's left can be thin — so margin and ROI matter more than revenue. The break-even price is the floor you can't go below, and max profitable ACoS is the advertising ceiling before a sale loses money.
How it’s calculated
Net = price − referral % − FBA fee − storage − product − shipping − ads − return loss. Break-even price = fixed costs ÷ (1 − referral %).

Common mistakes
- Forgetting storage, returns, and ad spend.
- Chasing revenue while the margin is razor-thin.

Frequently asked questions
What is ACoS?
Advertising Cost of Sale — ad spend as a percentage of sales. Stay below the 'max profitable ACoS' and your ads still leave a profit.
Why is ROI different from margin?
Margin is profit over price; ROI is profit over what you invested (product + shipping). ROI shows how hard your cash is working.
Are these the exact Amazon fees?
They're realistic defaults. Fees vary by category and product size — check Amazon's current fee schedule and enter your numbers.
What is the 3.5% fuel surcharge?
From April 17, 2026, Amazon applies a 3.5% fuel surcharge to FBA fulfillment fees in the U.S. It is charged on the fulfillment fee itself, not your sale price — on a $4.20 fee that's about $0.15 per unit. The calculator includes it by default; toggle it off to model pre-surcharge economics.
What are inbound placement fees?
Since 2024, Amazon charges a fee on standard-size units you send to its network — typically $0.21–$0.68 per unit depending on how many locations you split inventory to. Choosing the Amazon-optimized (multi-location) split reduces it to $0. Enter your per-unit rate or 0 in the placement field.
Which categories have the lowest Amazon fees?
Consumer Electronics, Computers, Full-Size Appliances, and Video Game Consoles pay just 8% referral. Tires pay 10%; Automotive and Industrial pay 12%. At the other end, Clothing over $20 pays 17% and Amazon Device Accessories pay 45%. Pick your category above and the calculator prices the exact tier, including the $0.30 minimum.
