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

Standard (2.9% + €0.30)
