Cost Per Lead (CPL)
What you paid to generate one lead
In Simple Words (Zero Jargon):
What you paid to generate one lead
Official Mathematical Equation
Total Ad Spend ÷ Number of Leads Generated
Why It Is Critical
CPL is the primary efficiency metric for B2B marketing, lead generation campaigns, and any business model where the sale happens offline or after a follow-up process. The critical caveat: a low CPL is meaningless without tracking what percentage of those leads actually convert to customers (lead quality).
Strategic Rules of Thumb & Execution Playbook
- Always track CPL alongside lead-to-close rate. A ₹200 CPL with a 2% close rate costs ₹10,000 per customer. A ₹600 CPL with a 15% close rate costs ₹4,000 per customer.
- Optimising purely for low CPL often produces high volume of low-quality leads - a trap that frustrates sales teams.
What You Get: The efficiency metric for lead-focused campaigns - most meaningful when paired with lead quality and conversion-to-customer data.
