Cost Per Lead Calculator for General Contractors - CPL Benchmark
Most general contractors waste 40% of their marketing budget on leads that never convert.
As a general contractor, your average job value of $75,000 means every wasted marketing dollar costs you dearly. This calculator reveals your true cost per customer (not just lead), factors in referral chains and repeat business, and shows exactly where you're bleeding money versus industry top performers.
Enter your monthly lead generation spend, lead volume, and conversion metrics. The calculator will reveal your true customer acquisition cost, compare it to industry benchmarks, and show optimization opportunities.

Cost Per Lead
$60
Solid CPL within industry standards. Focus on improving close rate through faster response times and better sales processes to maximize ROI.
True Cost Per Customer
$2,222
2-3% of job value is acceptable but not optimal. Focus on improving response time - getting under 30 minutes could cut this cost by 30%.
Marketing ROI
406.3%
Outstanding ROI - you're in the top 10%. Scale aggressively while monitoring quality. Consider expanding to adjacent markets or services.
LTV to CAC Ratio
40.5
Extremely high LTV:CAC suggests you're under-investing in marketing. Scale up aggressively - you have massive headroom for growth.
Monthly New Customers
1.35
Under 3 customers/month limits growth potential. Your close rate or lead volume needs improvement. Focus on response time and lead quality.

Methodology & Assumptions
This calculator goes beyond simple CPL by factoring in response time decay (leads lose 50% conversion potential after 1 hour), seasonal demand variations, referral chain value, and true lifetime customer worth. It reveals your real customer acquisition cost versus just lead cost.
Assumptions:
- Response time significantly impacts close rates based on lead decay studies
- Seasonal multipliers reflect typical general contractor demand patterns
- Referral rates generate additional lifetime value beyond initial job
- Profit margins remain consistent across different job sizes
- Lead quality is consistent across different sources
Limitations:
- Does not account for varying lead quality by source
- Assumes linear scaling of results with budget changes
- Seasonal patterns may vary by geographic location
How the Calculation Works
Calculates true customer acquisition cost by factoring in response time decay, seasonal adjustments, referral multipliers, and lifetime value ratios to determine marketing ROI
monthlyAdSpend = Total marketing investment per month
monthlyLeads = Raw lead volume generated
closeRate = Base conversion rate before adjustments
responseTime = Lead response speed affecting conversion
seasonalMonth = Seasonal demand multiplier
profitMargin = Net profit percentage per job
referralRate = Customer referral generation rate
