Get a Free QuoteHow the Amazon FBA Calculator Works
Selling on Amazon FBA means paying a referral fee (a percentage of the sale price that depends on your category) plus an FBA fulfillment fee (based on your product's size tier and weight). On top of that come your product cost, inbound shipping, prep, and monthly storage. This free calculator adds it all up to show your net profit per unit, profit margin, and return on investment (ROI), so you can price products and pick winners with confidence. Referral percentages are current US rates; FBA fulfillment fees are 2024/2025 US estimates you can edit to match your exact Seller Central fee.
Frequently Asked Questions
How is the FBA fulfillment fee calculated?
Amazon charges an FBA fulfillment fee based on your product's size tier (small standard, large standard, large bulky, etc.) and its unit weight. Enter your dimensions and weight and the tool estimates the fee — you can override it with your exact fee from Seller Central.
What is the Amazon referral fee?
The referral fee is a percentage Amazon takes from each sale, set by category — most categories are 15%, with electronics around 8% and apparel up to 17%. There's also a $0.30 minimum referral fee per item.
How accurate is this calculator?
Referral percentages are current US rates and very accurate. FBA fulfillment fees are 2024/2025 estimates by size tier — close, but always confirm your exact fee in Amazon Seller Central. Profit, margin, and ROI are computed exactly from your inputs.
