Profit Margin Calculator / Amazon FBA

Profit Margin Calculator for Amazon FBA Sellers

Amazon FBA sellers face a complex fee structure that makes margin calculation essential. Beyond product cost, FBA fees include referral fees (8-15% of sale price), fulfillment fees ($3-5+ per unit), monthly storage fees, and advertising costs. A product that appears to have a 60% gross margin before fees can easily drop to 15-20% net after Amazon takes its cut.

Margin Tips for Amazon FBA

✓Use the Amazon FBA Revenue Calculator before sourcing — a product needs at least 3x landed cost to work after all fees
✓Keep your product light and small: FBA fulfillment fees jump dramatically at size tier breakpoints (standard → oversize)
✓Long-term storage fees (charged quarterly) can destroy margins — maintain 60-90 days of inventory max
✓Aim for a minimum $10 profit per unit after all fees and ad spend — lower and one bad month wipes out profits
✓PPC advertising costs are rising 15-20% year-over-year on Amazon — factor in $3-5 ad spend per sale when calculating margin
