"Good enough" ROAS isn't a fixed number; it depends entirely on your profit margins, Customer Lifetime Value (LTV), and industry. Calculate your breakeven ROAS first (e.g., if 25% profit margin, 4:1 ROAS is breakeven). A common healthy range is 3:1 to 5:1, but it must align with your specific business profitability.
For calculating ROAS:
Basic ROAS: (Revenue / Ad Spend) - Use this for quick, platform-specific ad optimization.
True ROAS / Marketing ROI: (Total Revenue / Total Marketing Investment) - YES, factor in all costs like creatives, agency fees, website, tech, etc. This is essential for understanding your overall marketing profitability and strategic success.
