About this calculator
What percentage of revenue should go to marketing?
Commonly 5–10% for established home-service businesses, higher when growing into a new area. The right number is whatever keeps CPA below your maximum affordable figure.
Why does my cost per lead rise as I spend more?
You buy the cheapest, highest-intent inventory first. Additional budget reaches progressively less qualified audiences, so the marginal lead always costs more than the average one.
