How is this calculated?
Referral fee = Selling price × referral % ÷ 100
Amazon fees = Referral + FBA fee + Storage + Other Amazon fee
Total cost = Product + Amazon fees + Inbound + Prep + Advertising + Other
Net profit = Selling price − Total cost
ROI = Net profit ÷ your outlay (product + inbound + prep + other) × 100
Break-even price = the selling price where net profit is zero, solved to account for the percentage referral fee
Understanding FBA profitability
FBA profit is what remains after Amazon's fees and all of your own costs. Because the referral fee is a percentage and the FBA fee is fixed, small changes in price or product cost can swing a product from profitable to not.
Referral fee vs. FBA fee
The referral fee is a percentage commission on the sale; the FBA fulfillment fee is a fixed charge per unit for picking, packing, and shipping. Entering both, along with storage, gives a realistic view of what Amazon keeps.
Margin and ROI together
Margin shows profit as a share of the sale price; ROI shows it against the cash you put in to source the unit. Sellers often look at both — a healthy margin with weak ROI (or the reverse) tells you where to focus.
Use your own numbers
The accuracy of the result depends entirely on the fees you enter. Pull your current referral percentage and FBA fee from Seller Central rather than relying on the example defaults.
Frequently asked questions
What is an Amazon FBA profit calculator?
It works out your net profit, margin, ROI, and break-even price on an Amazon FBA product after the referral fee, FBA fulfillment fee, and your own costs. You enter your fees, so it stays accurate to your account.
What fees do Amazon FBA sellers pay?
The main ones are the referral fee (a percentage of the sale price), the FBA fulfillment fee (a fixed amount per unit based on size and weight), and storage fees. On top of Amazon's fees you also pay for the product, inbound shipping, prep, and advertising.
How do I calculate Amazon FBA profit?
Start with the selling price, subtract the referral fee and FBA fee, then subtract your product cost, inbound shipping, prep, advertising, and any other costs. What remains is your net profit per unit.
What is the Amazon referral fee?
The referral fee is Amazon's commission on each sale, charged as a percentage of the selling price. The exact percentage depends on the product category, so enter the rate that applies to yours.
Where do I find my exact FBA fees?
Your current referral percentage, FBA fulfillment fee, and storage fees are shown in Amazon Seller Central and in Amazon's published fee schedules. This calculator does not fetch them — enter the figures from your own account for an accurate result.
What is a good FBA margin or ROI?
There is no universal number — it depends on your category, price point, and how much you reinvest in advertising. Use the break-even price and ROI here to compare products, rather than aiming for a fixed benchmark.
How is the break-even price calculated?
It is the selling price at which net profit is zero. Because the referral fee is a percentage of the price, the calculator solves for it rather than simply summing costs, so the percentage fee is handled correctly.
