Amazon FBA example at 15% referral
Many US categories cluster near a 15% referral fee. For a $29.99 sale: 15% × 29.99 = $4.4985 → $4.50 (above the $0.30 minimum).
If FBA fulfillment is $5.41 (user-supplied from fee preview) and landed product cost is $8.50:
- Amazon fees ≈ 4.50 + 5.41 = $9.91
- Net ≈ 29.99 − 9.91 − 8.50 = $11.58 (~38.6% margin)
This ignores PPC, storage, returns, and inbound freight. Use Seller Central for authoritative fees, then sketch with our Amazon FBA calculator.
