How it is calculated
CPL = ad spend ÷ number of leads. A lead is early-stage interest (a form submission, a contact, a demo request), not a sale itself — it still needs to be qualified and closed into a deal.
CPL is always lower than CAC (customer acquisition cost), because CAC divides by customers who actually bought, not everyone who submitted a form — some share of leads never convert. The ratio between CPL and CAC gives an indirect read on how efficiently sales turns leads into customers.
Cheap leads aren't automatically a win: if a lower CPL comes from a less targeted audience, lead-to-sale conversion can drop enough that the resulting CAC actually rises, even though CPL itself went down. CPL is best read alongside lead-to-sale conversion, not on its own.
