Net Profit = Sale Price - Product Cost - Amazon Referral Fee (15%) - FBA Pick & Pack Fee - Inbound ShippingDeducts category referral fees (typically 8% to 15%) and weight-tiered FBA fulfillment fees to calculate net per-unit profit.

- Product Size & Weight Tier: Small standard, large standard, or oversize weight bracket.
$34.99 Retail Price, $8.00 COGS, Standard 1.2 lb Size Item
Calculating Amazon FBA fees and net profit margin.
- Amazon Referral Fee (15%): $34.99 × 0.15 = $5.25.
- FBA Fulfillment Fee (Standard 1.2 lb): ~$4.75.
- Total Amazon Fees: $5.25 + $4.75 = $10.00 (28.6% of sale price).
- Net Profit per Unit: $34.99 - $8.00 - $1.20 - $10.00 = $15.79.
- Net Margin %: ($15.79 / $34.99) × 100 = 45.1%.
