Cost Per Lead Calculator

Marketing cost-per-lead calculator using campaign spend, leads, and customers to estimate CPL, lead conversion, and CAC.

Cost per lead (CPL) divides campaign spend by generated leads. Add customer count to estimate lead-to-customer conversion and acquisition cost.

Use consistent attribution and include the costs relevant to the decision. Ad spend alone can understate cost when creative, software, agency, and sales labor are material.

Frequently asked questions

What counts as a lead?

Use a documented definition, such as a completed qualified inquiry, consistently across campaigns.

Is cost per lead the same as CAC?

No. CPL measures generated leads; customer acquisition cost divides cost by customers acquired.

Which costs should I include?

Match the cost scope to the decision and use it consistently across comparisons.
