About the Cost Per Lead Calculator

Cost per lead is the first honest number in any lead-generation channel: what it actually costs to get one person to raise their hand. It sits earlier in the funnel than CAC, which is why a channel can look cheap on CPL and still lose money once the leads fail to close.

Enter what a campaign cost and how many leads it produced, and the CPL appears straight away, along with how many leads $1,000 buys at that rate. Add your lead-to-customer conversion rate and it also works out what a customer really costs through that channel — usually the figure that settles an argument about budget.
