ROAS and Publisher Profitability FAQ
Practical answers for ROAS, break-even planning, CAC payback, and benchmark interpretation.
What is a good ROAS for ad-supported publishers?v
There is no universal number. Use break-even ROAS from your contribution margin first, then compare against your own weekly RPM trend and payback target.
Is high ROAS always profitable?v
No. High ROAS can still lose money if margins are thin or fixed costs are ignored. Always include fulfillment, platform fees, and operating costs.
How is ROAS different from CAC and MER?v
ROAS measures campaign revenue efficiency, CAC measures cost per new customer, and MER measures blended efficiency across total marketing spend.
When should I scale ad spend?v
Scale when ROAS is consistently above break-even, CAC payback is stable, and conversion quality remains healthy for multiple review cycles.
Do you store my calculator inputs?v
No. Inputs are processed in-browser and are not persisted to your account because calculators do not require user accounts.
Where can I get benchmark updates?v
Use the benchmark email signup modules on calculator and blog pages to receive weekly RPM/ROAS updates and the 2026 benchmark sheet.
