Amazon FBA Net Profit Formula

Transparent mathematical methodology explained in plain English.

Net Profit = Sale Price - Product Cost - Amazon Referral Fee (15%) - FBA Pick & Pack Fee - Inbound Shipping

Deducts category referral fees (typically 8% to 15%) and weight-tiered FBA fulfillment fees to calculate net per-unit profit.

Variables Explained:

  • Item Sale Price ($): Retail listing price on Amazon.
  • Item Cost / COGS ($): Unit manufacturing or sourcing cost.
  • Product Size & Weight Tier: Small standard, large standard, or oversize weight bracket.
Real Project Example

$34.99 Retail Price, $8.00 COGS, Standard 1.2 lb Size Item

Calculating Amazon FBA fees and net profit margin.

Sample Project Inputs:
Sale Price:$34.99
Item COGS:$8.00
Inbound Ship:$1.20
Referral %:15%
Step-by-Step Calculation:
  1. Amazon Referral Fee (15%): $34.99 × 0.15 = $5.25.
  2. FBA Fulfillment Fee (Standard 1.2 lb): ~$4.75.
  3. Total Amazon Fees: $5.25 + $4.75 = $10.00 (28.6% of sale price).
  4. Net Profit per Unit: $34.99 - $8.00 - $1.20 - $10.00 = $15.79.
  5. Net Margin %: ($15.79 / $34.99) × 100 = 45.1%.
Calculated Answer:$15.79 net profit per unit (45.1% net margin after $10.00 Amazon fees).
