This calculator reveals your true cost per customer, profit per marketing dollar, and shows exactly where you stand against top performers in your market.
Enter your current lead generation spending, lead volume, close rate, and average job details. The calculator will show your complete customer acquisition picture and identify the biggest opportunities to improve profitability.

Methodology & Assumptions
This calculator accounts for the complex reality of contractor lead generation by factoring response time impact on close rates (leads contacted within 5 minutes close at 100% baseline rate, while those contacted after 24 hours close at only 15%), seasonal demand fluctuations specific to construction, and lifetime customer value including referral multiplication effects. It calculates true profitability by using net margins rather than gross revenue.
Assumptions:
- Response time directly impacts close rates based on Harvard Business Review lead response study
- Seasonal factors affect both lead quality and close rates for construction trades
- Referrals generate additional lifetime value at 80% the rate of the referral percentage
- Profit margins are calculated after all direct costs including labor, materials, and overhead
- Customer acquisition costs should be recovered within first job for sustainable growth
Limitations:
- Does not account for lead source quality differences (Google vs Facebook vs Home Advisor)
- Assumes consistent monthly performance without major market changes
- Referral value calculation is simplified and may vary based on referral program structure

monthlyLeads = Raw lead volume generated
closeRate = Base close rate percentage
avgJobValue = Average project revenue
profitMargin = Net profit margin percentage
responseTime = Lead response speed (affects close rate)
seasonalFactor = Seasonal demand adjustment
referralRate = Customer referral generation rate
