Amazon & Marketplace Selling: Margin Math

Understand ACoS, BSR, and when to kill a product.

📚 9 articles⏱️ ~2.5 hoursBeginner–Intermediate

About This Learning Path

Amazon takes a huge cut (15-45% depending on category), and FBA fees are opaque. You'll learn ACoS (advertising cost of sale — are your ads profitable?), TACoS (total advertising cost of sale — ad spend as % of revenue), BSR (best seller rank — is this product moving?), and most importantly: gross margin after FBA fees, returns, and ads. You'll understand why a product that shows 40% gross margin on paper might actually lose money, and how to calculate the true profitability that tells you whether to scale or kill a listing.
