How this calculator works
CPL = ad spend ÷ leads. Compare it to the value of a lead (close rate × deal value) to know whether your campaigns are profitable. Facebook lead-ad CPLs commonly range from $5 to $50.
Frequently asked questions
What's a good cost per lead on Facebook? +
It depends entirely on what a lead is worth to you. B2C CPLs of $5–$20 are common; B2B can run $30–$100+ and still be profitable.
How do I lower my cost per lead? +
Use native lead forms, sharpen your offer, test creative, and exclude low-intent audiences to focus spend on people likely to convert.
Is a low cost per lead always better? +
Not on its own. Cheap leads that rarely convert can cost more than pricier high-quality leads. Track lead-to-customer rate alongside CPL to judge true value.
How do I know if my cost per lead is profitable? +
Compare CPL to the value of a lead, which is your close rate multiplied by average deal value. As long as that value comfortably exceeds CPL, the campaign is profitable.
Do native lead forms lower cost per lead? +
Often yes. Instant forms keep users on Facebook and pre-fill fields, reducing friction and typically producing a lower CPL than sending traffic to an external landing page.
