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.
