Price → COGS → FBA → Referral → PPC = Real Net Profit
Stop thinking gross revenue is profit. This tool exposes your true margin after every Amazon fee, your cost of goods, and ad spend — with a health scorecard, ACoS target, and inventory ROI built in.
Amazon no longer offers FBA labeling, poly bagging, or bubble wrap services. Every unit must arrive 100% compliant or face defect fees.
💸
FBA Fees Increased (avg +$0.08/unit)
Small standard ($10–$50): +$0.25. Over $50: +$0.51. Extra-Large: −$2.08 (reduced). Low-Price under $10: $0.86 discount vs standard.
⚠️
New Inbound Defect Fee: $0.60/unit
Labeling errors or routing mistakes now trigger a $0.60/unit defect fee — consolidated from multiple 2025 penalties. Zero if always compliant.
🏗️
New Size Tiers: Small Bulky + Large Bulky
Amazon split the old "Large Bulky" tier. SIPP discount removed for bulky items. Overmax surcharge added for items exceeding 96" on longest side.
