Ehsan's Insight
ROAS (Return on Ad Spend) is the most commonly reported paid marketing metric and the most commonly misinterpreted. A ROAS of 3x sounds healthy: spend $1, get $3 in revenue. But revenue is not profit. If your gross margin is 50%, that $3 in revenue produces $1.50 in gross profit. After the $1 ad spend, you have $0.50 in contribution margin. At 30% gross margin, ROAS of 3x produces $0.90 in gross profit minus $1 in ad spend = -$0.10 loss per acquisition. You are losing money on every sale. The break-even ROAS formula: 1 ÷ gross margin percentage. At 50% margin, break-even ROAS is 2.0x. At 30% margin, break-even ROAS is 3.3x. Any ROAS below your break-even point means paid ads are unprofitable before accounting for overhead.
