The ROAS Truth
Vanity metrics kill businesses. Know your floor.
How it works
Enter your Average Order Value (AOV).
Subtract COGS (Product + Shipping).
Factor in Merchant Fees (Stripe/PayPal).
Set your desired Net Profit margin.
The remainder is your Max CPA (Cost Per Acquisition).
Why it matters
Most dropshippers and e-com founders focus on revenue. But if your ROAS floor is 3.5x and you're celebrating 2.0x, you are scaling a loss.
This tool visualizes exactly where every dollar goes, so you know your "Walk Away" number.
The Math
Max CPA = AOV - COGS - Fees - Profit
Min ROAS = AOV / Max CPA
