Know your real number before you spend a cent on ads.

This calculator tells you exactly what you can afford to pay per customer — the one number that should drive every ad decision you make, and the one most people skip entirely.

What's inside:

• Auto-calculates true break-even price, margin %, and Max Ad Spend Per Sale
• Built-in guardrails so you never accidentally advertise a product you can't actually afford to sell
• Feeds directly into your ad targets — know your ceiling before you hit "publish"

Enter your costs once. Know exactly where you stand.
