Marketing calculator
Google Ads Budget Calculator
Set a target job count and funnel rates - see the monthly Google Ads budget required.
How the formula works
Required spend = Target jobs × CPC ÷ (Landing CVR × Lead → appt × Show rate × Close rate). Example: 3 jobs at $30 CPC with a 9% → 45% → 80% → 35% funnel ≈ $7,900/mo in ad spend.
Frequently asked questions
How does the Google Ads budget calculator work?
It reverses the funnel: target jobs → required leads → required clicks → required spend at your CPC and conversion rates.
What if my funnel rates are low?
Small improvements in lead → appointment or close rate dramatically reduce the budget needed for the same job count.
Are the default numbers realistic?
Defaults reflect typical home service Google Ads ($25-$40 CPC, 7-12% landing CVR). Your market and trade will differ - plug in your own data from Google Ads and your CRM.
