Frequently Asked Questions
What is ROAS?
Return On Ad Spend (ROAS) measures revenue generated for every dollar spent on advertising. Formula: Revenue ÷ Ad Spend. A ROAS of 4x means you earned $4 for every $1 spent.
What is a good ROAS?
Google recommends a minimum of 4x as a starting target. However, your break-even ROAS depends on your gross margin — at 25% gross margin, break-even ROAS is 4x. Higher margins allow profitable campaigns at lower ROAS.
ROAS vs ROI — what's the difference?
ROAS only accounts for ad spend. ROI accounts for all costs including COGS, overhead, and fulfillment. ROAS of 4x can still be unprofitable if your margins are thin. Use our Break-Even ROAS calculator to find your true floor.
