You’re Calculating Break-Even ACOS Wrong. Most Sellers Just Use Their Cogs, but If You Have Repeat Buyers? that Number Is Way Off. (I Built a Free Tool for This)
If 30% of your revenue comes from returning customers…
Then your true break-even ACOS could be 60%, 80%, even 100%+
and you’d still be profitable.
But if you’re not calculating lifetime value by SKU, you’re guessing on bids… and leaving growth on the table.
So we built a free tool to fix that:
✅ Upload your FBA shipment CSVs
✅ Analyze repeat vs new buyers per SKU
✅ Get your actual customer lifetime value
✅ Instantly calculate break-even ACOS for every product
Just real customer data → real margin clarity → real growth.
The tool is 100% free.
