Methodology & Assumptions
This calculator accounts for the unique dynamics of windows and doors lead generation: seasonal demand fluctuations (40% higher close rates in peak season), response time decay (leads contacted after 1 hour close at 50% the rate), referral chain value (average customer refers 1.2 additional customers over 2 years), and lifetime value including repeat business and referrals.
Assumptions:
- Response time directly impacts close rates based on home improvement lead studies
- Seasonal factors reflect actual windows/doors demand patterns with winter being 30% slower
- Referral rates include both direct referrals and repeat business for additional projects
- Profit margins account for material costs, labor, and overhead typical in window installation
- Lead quality varies by source but averages are based on mixed digital marketing channels
Limitations:
- Doesn't account for geographic variations in labor costs and market pricing
- Assumes consistent lead quality across different marketing channels
- May not reflect brand premium pricing for luxury window manufacturers
