Math First, Ads Second
The Trap
You launch Facebook ads because \"that's what e-commerce stores do.\" You set a budget of $50/day. You get some sales. You feel good. At the end of the month, you check your bank account and realize you lost $1,000. You were practicing \"Hope Marketing\"—spending money and hoping the algorithm performs magic.The Reality
Advertising is not a slot machine; it is an equation. If you do not know your Break-Even ROAS (Return on Ad Spend) before you launch, you are gambling. You cannot \"optimize\" an ad account if you don't know the target number.The \"Napkin Math\" You Must Do:
- Calculate Margin: Selling Price ($50) - COGS ($15) - Shipping ($10) = $25 Profit Margin.
- Calculate Break-Even CPA: You can spend up to $25 to acquire a customer to break even.
- Calculate Break-Even ROAS: Selling Price ($50) / Break-Even CPA ($25) = 2.0.
The Rule: If your ads are running at a 1.5 ROAS, you are losing money on every sale. Turn them off immediately. If you didn't know your target was 2.0, you would have kept them running, thinking \"1.5 is pretty good!\"
