How this tool works
ROAS = attributed revenue ÷ ad spend. Profit estimate = attributed revenue × contribution margin − ad spend − other campaign costs. Break-even revenue = (ad spend + other costs) ÷ margin. It excludes fixed overheads, VAT/taxes, delayed conversions and attribution errors.
Practical tip
A ROAS of 4× is not automatically profitable: at a 20% contribution margin, ignoring other costs, you need 5× to cover ad spend.
