how it's calculated
Simple arithmetic, shown so you can check it.
- Clicks = budget ÷ cost per click
- Conversions = clicks × conversion rate
- Cost per conversion = budget ÷ conversions
- ROAS = conversion value ÷ budget
- Profit after ad spend = conversion value × margin − budget
- Max cost per conversion = value per conversion × margin
- Max cost per click = value per conversion × margin × conversion rate
- Minimum ROAS = 1 ÷ margin
These are estimates, not forecasts. Real cost per click and conversion rates vary by keyword, season and competition, and new campaigns usually need a few weeks of data before they settle. The profit figure excludes management fees and other costs. Your inputs stay in your browser; the page URL keeps them so you can share a scenario.
