Amazon FBA Profit Calculator
Work out profit, margin and ROI for a product sold through Fulfillment by Amazon — referral fee, FBA fulfillment fee, monthly storage, inbound shipping, product cost and ads — per unit and per month.
Results are estimates for planning; real-world values vary.
How to use
- 1Enter the selling price and your product cost.
- 2Enter the FBA fulfillment fee for your size tier (from Seller Central's Revenue Calculator) and the referral fee for your category.
- 3Add storage, inbound shipping and advertising per unit to see true profit.
How it's calculated
Profit per unit = price − referral fee (price × %) − FBA fulfillment fee − storage − inbound shipping − product cost − ad spend per unit. Margin = profit ÷ price. ROI = profit ÷ (product cost + inbound shipping).
Frequently asked questions
What's the Amazon referral fee?
Usually 15% of the sale price for most categories (8% for some electronics, 17% for clothing above certain prices, with a $0.30 minimum per item). Check Amazon's current fee schedule for your category.
Where do I find the FBA fee?
It depends on the product's size tier and shipping weight, and changes periodically. Use Amazon's FBA Revenue Calculator or the fee preview in Seller Central.
What's a healthy FBA margin?
Many sellers aim for at least 25–30% net margin and 100% ROI to absorb returns, price drops and fee changes.
