Six calculators for planning, pacing, guardrails and growth. Choose a model, set assumptions, and stress-test outcomes before you spend.
Set max CPA/CPC and break-even ROAS guardrails from margin targets before scaling spend.
| Scenario | Break-even ROAS | Max CPA | Max CPC | Required CVR |
|---|---|---|---|---|
| Conservative | 2.35x | £34.75 | £1.00 | 5.18% |
| Base | 2.08x | £42.05 | £1.35 | 4.28% |
| Aggressive | 1.96x | £45.75 | £1.61 | 3.93% |
Guardrails tighten quickly as margin drops or refund/churn increases.
We can benchmark these assumptions against your live Google Ads structure, search terms, tracking, and spend efficiency.
