Solar Lead Generation ROI Calculator - Measure Your Lead Spend
Are you spending $75 per lead without knowing if it's profitable?
Solar installation requires significant lead investment, but with average job values of $25,000+, even small improvements in lead ROI can add tens of thousands to your annual profit. This calculator reveals your true cost per customer, profit per lead dollar spent, and identifies the exact metrics to optimize for maximum growth.
Enter your current lead generation spend, lead volume, close rates, and job values. The calculator will show your true ROI, benchmark your performance against top solar installers, and reveal which metric to improve first for maximum profit impact.
Your Numbers
Total monthly spend on ads, lead services, and lead generation tools
Total qualified leads received per month from all sources
Percentage of leads that convert to signed contracts
Average contract value including panels, installation, and add-ons
Net profit margin after all costs (materials, labor, overhead)
How quickly you typically respond to new leads
Current seasonal period affecting lead quality and close rates
Percentage of customers who refer new business
Cost Per Lead
$0
Outstanding CPL for solar leads. Scale up ad spend immediately - you have significant room before diminishing returns. Focus on increasing lead volume while maintaining quality.
Cost Per Customer
$0
Outstanding customer acquisition cost. You're converting leads efficiently - increase ad spend to capture more market share before competitors catch up.
Monthly Lead ROI
0.0%
Lead spend is unprofitable. Stop all paid advertising immediately. Focus on referrals, improve close rates, or find cheaper lead sources before resuming paid campaigns.
LTV:CAC Ratio
0
LTV:CAC ratio below 3:1 is unsustainable for solar. Customer value doesn't justify acquisition cost. Focus on increasing job value through add-ons (batteries, EV chargers) or reducing acquisition costs.
Impact of 5% Better Close Rate
$0
A 5% close rate improvement adds modest monthly profit. Focus on faster response times and better lead qualification to achieve this easily.

Methodology & Assumptions
This calculator measures true lead generation ROI by accounting for response time impact on close rates (5-minute response converts 40% better than 1-hour response), seasonal variations in solar lead quality, lifetime customer value including maintenance contracts and referrals, and total customer acquisition cost versus lifetime profit generated.
Assumptions:
- Response time directly impacts close rate based on solar industry studies
- Seasonal factors affect lead quality and conversion rates
- Average 8% repeat business rate for maintenance and upgrades
- Referrals generate 1.5x higher lifetime value customers
- Profit margins remain consistent across different lead sources
Limitations:
- Does not account for lead source quality variations
- Assumes consistent sales team performance
- Regional market differences not factored in calculation
How the Calculation Works
Calculates true lead generation ROI by factoring in response time impact on close rates, seasonal adjustments, lifetime value including repeat business and referrals, and total customer acquisition cost versus profit generated
monthlyAdSpend = Total monthly investment in lead generation
monthlyLeads = Number of qualified leads generated monthly
closeRate = Base close rate percentage
avgJobValue = Average contract value per customer
profitMargin = Net profit margin after all expenses
responseTime = Speed of lead follow-up affecting close rate
seasonalFactor = Seasonal adjustment for close rate optimization
referralRate = Customer referral rate for lifetime value calculation
