How to Know When to Cut an Unprofitable Amazon SKU

The hardest decision in Q1 is knowing when to kill a SKU that "feels" like it is working. Revenue looks solid, units move daily and your listing ranks on page one.

But when you audit the P&L, the SKU bleeds margin on every sale.This happens when brands optimize for vanity metrics instead of profit.

They track sales velocity and ROAS. But they ignore the real math, like contribution margin and storage costs.

Here are the warning signs you need to look for:
‍

• The ACoS Gap: Your ACoS is 35% while your break-even is 22%. You are scaling losses instead of profit.
  ‍
• ‍Storage Creep: Storage fees grow faster than sales. The inventory moves too slowly despite appearing active.
  ‍
• ‍The Return Drain: Returns exceed 15%. This destroys unit economics through replacement and disposal costs.

Every dollar spent defending a losing SKU is a dollar not invested in your winners. Portfolio discipline means cutting aggressively even when it hurts.
‍

This is how top operators handle the audit:
‍

• Check every SKU quarterly.
  ‍
• The 60-Day Rule: Cut ad spend immediately if margin targets aren't met within 60 days.
  ‍
• The 90-Day Rule: If it still underperforms after 90 days, liquidate inventory and move on.
  ‍

This isn't just about cleaning up the catalog. It is about realizing that revenue without profit isn't growth. It is expensive noise.
