Visible Math Breakdown
- installs_per_month = leads_purchased_per_month × close_rate = 1200 × 0.080 = 96.0
- cost_per_install = cost_per_lead ÷ close_rate = 12 ÷ 0.080 = 150.00
- monthly_lead_spend = cost_per_lead × leads_purchased_per_month = $14,400
- gross_margin_total = installs_per_month × avg_system_gross_margin = $940,800
- net_profit_after_sales = gross_margin_total - monthly_lead_spend - monthly_sales_cost = $908,400
- appointments = leads_purchased_per_month × appointment_rate = 264.0

How to Use This Solar ROI Calculator
This tool is built for operators running real acquisition budgets, not vanity forecasting. Start with your current lead cost and close rate, then pressure-test how small conversion changes affect cost per install and monthly profit.
Install Economics Over Lead Volume
MarketPulseMaps is built as solar acquisition infrastructure: territory intelligence, install-eligible homeowner targeting, and API delivery workflows. The core objective is predictable install volume, not random list volume.
