CAC calculator
What does a customer actually cost you?
Most contractors and realtors do not know their real customer acquisition cost. The number is usually higher than they think — sometimes 2-3× higher once you account for retainer plus ad spend plus tool subscriptions.

Your real numbers depend on niche, market, and current baseline. We model your specific math live in the strategy call.
How CAC math works
The numbers nobody actually does for you.
Cost per lead
Total marketing spend divided by leads generated. Most operators only count ad spend; the real number includes agency retainer + tools + opportunity cost of time spent on marketing.
CAC
Cost per acquired customer. Cost per lead divided by close rate. A $80 lead at 25% close = $320 CAC. A $40 lead at 15% close = $267 CAC. Both metrics matter.
LTV/CAC ratio
Lifetime value divided by acquisition cost. Healthy floor is 3:1; strong is 5:1+. Below 3:1 you are losing money on every customer once retention costs are factored in.
- HomeAdvisor / Yelp / Zillow Premier Agent leads typically run $200-500 per lead with 10-20% close rates — CAC commonly lands at $1,500-3,000 per customer.
- Owned-channel leads (SEO, GBP, content) typically run $20-80 per lead with 35-55% close rates — CAC lands at $50-200 per customer once compounding.
- The math difference compounds over years. Switching channels in year 1 saves 10-30%; sticking with the wrong mix for 3+ years can mean 50-80% margin destruction at scale.
