ROI Calculator / Google Ads

ROI Calculator for Google Ads & PPC

Google Ads ROI (or ROAS — Return on Ad Spend) measures how much revenue each dollar of ad spend generates. The average Google Ads ROAS across industries is around 2:1, but well-optimized campaigns in high-intent verticals (legal, home services, SaaS) regularly achieve 4:1 to 8:1. The key variables are click-through rate, cost per click, conversion rate, and average order value. Improving any one of these by 20% has a multiplicative effect on your ROI.

ROI Tips for Google Ads

✓Target a minimum 3:1 ROAS (300% ROI) to remain profitable after product costs, overhead, and management fees
✓Focus on high-intent keywords — "buy X" and "X near me" convert 2-3x better than informational queries
✓Include management costs in your ROI calculation: agency fees (15-20% of spend) or your own time managing campaigns
✓Track conversions at the keyword level, not just campaign level — 20% of keywords typically drive 80% of conversions
✓Use negative keywords aggressively — most accounts waste 20-30% of budget on irrelevant searches without proper negatives
