What is a good ROAS?

ROAS (Return On Ad Spend) measures how much revenue each euro of advertising brings. Formula: ROAS = revenue ÷ ad spend. A "good" ROAS depends on your margin, not a magic number. The real benchmark is your break-even = 1 ÷ gross margin. At 60% margin you're profitable from 1.67×.

⚠️ Most tools compute ROAS on pixel-declared conversions, not revenue actually collected — an inflated number that doesn't match your cash.
