Summary
What Is Cost Per Lead?
Cost per lead (CPL) is the amount a marketer pays for each new lead acquired, calculated as total campaign spend divided by the number of leads generated. It is the core efficiency metric for lead-generation marketing — paid search, LinkedIn campaigns, content offers, and landing-page programs — where the deliverable is a qualified contact rather than a sale. CPL tells you how expensive your demand engine is, but on its own it cannot tell you whether the leads are worth buying. That requires the second half of the funnel: how many of those leads qualify, close, and become profitable customers. This calculator connects both halves so you can see the full chain from spend to revenue.
How to Use This Calculator
Enter your total marketing spend and the leads it produced for the headline CPL. The Advanced Options add funnel quality: the qualification rate is the share of leads that meet your criteria (budget, authority, need, timeline), and the close rate is the share of qualified leads that become customers. From these the calculator derives the cost per qualified lead and the cost per closed deal — the true acquisition cost — plus estimated revenue when you provide an average customer value. The gap between CPL and cost per deal is usually large: a $12 CPL with a 60% qualification rate and a 15% close rate means each customer costs $133 to acquire.
Benchmarks and Interpretation
Typical CPLs range from $5 for low-intent B2C offers to $100+ for enterprise B2B software, with paid search and LinkedIn the most expensive channels and organic and referral the cheapest. Rather than chasing a low CPL, target a cost per deal that is a small fraction of customer value — a common rule is that acquisition cost should stay below a third of first-year customer value for healthy unit economics. If your cost per deal exceeds that, either the CPL is too high, the funnel leaks too much, or the offer is not attracting qualified buyers. Use this calculator to identify exactly which stage is breaking your economics.
