Cost per lead formula
Divide campaign spend by recorded leads from the same campaign and reporting window.
Calculate cost per lead from matched campaign spend and lead volume, then model a declared target without treating leads as customers.

CPL stops at the recorded lead. Compare it with customer acquisition cost only after the same cohort has enough downstream outcomes.

3,600 ÷ 120 = 30
Divide campaign spend by recorded leads from the same campaign and reporting window.
Use one currency, channel definition, attribution window, and date range.
A target CPL can show the spend implied by current lead volume and the leads required for current spend.
A lower CPL is not automatically better when qualification or close rate changes.

Compare the result with the customer acquisition cost calculator after leads become customers.
Use one currency, channel definition, attribution window, and date range.
Do not mix billed spend from one period with leads from another.
A target CPL can show the spend implied by current lead volume and the leads required for current spend.
Use the CPC calculator to separate the cost of a click from the cost of a recorded lead.
A lower CPL is not automatically better when qualification or close rate changes.
The calculator does not claim that a lead is a customer or that spend caused every recorded lead.
Divide campaign spend by recorded leads for the same campaign and reporting period.
No. CPL stops at a lead; CAC measures the cost of acquiring a customer.
There is no universal target. Evaluate CPL against lead quality, close rate, margin, and customer value.
