Formula and method

ROAS = Revenue ÷ Ad spend Break-even ROAS = 1 ÷ Margin

Worked example

With revenue from ads = $6,000, ad spend = $1,500, gross margin = 40 %, the ROAS Calculator returns roas: 4.00×; roas as percent: 400.00%; profit after ad spend: $900.00.

Tips for better results

  • Track LTV:CAC — a ratio of 3:1 or higher is a common healthy benchmark.
  • ROAS must exceed 1 ÷ margin to be profitable, not just exceed 1.
  • Ad revenue varies widely by niche, country and season — use your own historical RPM when you have it.

⚠️ Revenue estimates depend on your traffic quality, niche and ad network policies; actual earnings will differ.
