Methodology & Assumptions
This calculator models realistic lead generation ROI by factoring in response time effects (leads contacted within 15 minutes close at 2x the rate), seasonal demand fluctuations, and referral chain value. It applies industry-specific close rates and job values for general contractors, then calculates true profitability after all costs.
Assumptions:
- Referrals generate 30% additional lifetime value through word-of-mouth multiplication
- Response time directly impacts close rates based on lead studies (15 min = +40%, 4+ hours = -50%)
- Seasonal factors range from 0.6x (winter) to 1.4x (spring peak)
- Profit margins include all overhead, labor, materials, and operating expenses
Limitations:
- Does not account for lead quality variations between sources
- Assumes consistent close rates across all lead types and project sizes
- Seasonal factors are averages and may vary by geographic region
How the Calculation Works
Calculates net monthly profit from lead generation by multiplying leads by close rate, job value, and profit margin, then applies seasonal adjustments, response time multipliers, and referral value before subtracting costs
monthlyLeads = Number of leads generated per month
closeRate = Percentage of leads that convert to customers
avgJobValue = Average revenue per completed project
profitMargin = Net profit percentage after all expenses
seasonFactor = Seasonal demand adjustment multiplier
referralRate = Percentage of customers who provide referrals
responseTime = Speed of lead response affecting close rates
monthlyCost = Total monthly lead generation expenses
