What is Amazon FBA Fee Margin Calculator?

Amazon FBA sellers face a complex stack of fees — referral fees, fulfillment fees, storage fees — that can quietly erode your margins. This calculator consolidates all those costs and shows you the real profit you keep from every unit sold on Amazon.

How to Use This Tool

1. Enter your product's selling price. 2. Input your total product cost including sourcing and shipping to Amazon. 3. Add your estimated FBA fulfillment and referral fees. 4. Calculate your net profit per unit.

💡 Pro Tip: Amazon's referral fee varies by category — from 6% for electronics to 17% for jewelry. Always use your actual category rate, not a generic average, for an accurate calculation. Run this before ordering any new inventory!
