Methodology & Assumptions
This calculator provides a comprehensive view of lead generation ROI by factoring in real-world variables that most contractors ignore. It adjusts close rates based on response time (studies show 5-minute responses convert 9x better than 30-minute responses), seasonal patterns typical in construction, and includes referral value to calculate true customer lifetime worth. The tool reveals not just whether you're profitable, but which specific improvements would have the biggest impact on your bottom line.
Assumptions:
- Response time significantly impacts close rates based on Lead Connect studies showing dramatic conversion decay
- Seasonal adjustments reflect typical construction industry demand patterns with 15% boost in peak season
- Referral value calculation assumes 80% of referrals close at standard profit margins
- Profit margins include all business overhead and owner compensation
- Lead quality remains consistent across all lead sources and seasons
Limitations:
- Does not account for varying lead quality between different sources (Google Ads vs. Home Advisor vs. referrals)
- Seasonal adjustments are industry averages and may not reflect your specific market conditions
- Assumes consistent sales process and team performance across all leads
How the Calculation Works
Calculates comprehensive lead generation ROI factoring in response time impact, seasonal adjustments, referral value, and true customer acquisition costs. Response time dramatically affects close rates (5-minute responses close at 100% baseline, while 4+ hour responses close at only 30%). Seasonal factors adjust for typical construction industry patterns.
