Cost Per Lead Calculator

About this calculator

Cost per lead (CPL) is one of the most basic marketing efficiency metrics: total marketing spend ÷ number of leads generated. Unlike cost per click or cost per impression, CPL is tied to an actual expression of interest — a form fill, a signup, a demo request — rather than just traffic.

Marketing and demand generation teams track CPL by channel (paid search, social ads, content, events) to see where budget is being spent most efficiently, and use it alongside the lead-to-customer conversion rate to work out true customer acquisition cost — a channel with a low CPL but poor lead quality can end up costing more per customer than a pricier, higher-quality channel.
