ROAS and CPA calculator
Work backwards from margin, revenue and qualified conversions. ROAS and CPA or CPL decide whether the traffic is commercially viable; max CPC is only a guardrail because better clicks often cost more.
ROAS calculator FAQ
Is this mainly a max CPC calculator?
No. Max CPC is only a guardrail. ROAS, CPA or CPL, contribution after ad spend and customer quality matter more because better clicks often cost more.
Why include CPA or CPL on a ROAS calculator?
ROAS can hide weak acquisition quality. CPA or CPL helps you understand whether the cost of each order, lead or qualified enquiry is commercially acceptable.
What should I do if the calculator says the account is not viable?
Check tracking first. If revenue, lead quality or conversion value is wrong, the calculator will only make the wrong answer look precise.
ROAS and CPA only work when the revenue is trustworthy
If GA4, Google Ads and your actual order or lead data disagree, fix the measurement layer before scaling spend.
