Lead Generation & Prospecting
Lead quality, campaign economics, outbound reply and meeting metrics, SDR planning.
These ten calculators follow a prospect from first contact to qualified meeting: what a lead costs, how many reply, how many book and attend, and how much outreach a deal target really requires.
Each rate depends on its denominator. Count unique people rather than messages, keep the same campaign and period on both sides of the division, and remember that a cheap lead or a reply is not yet qualified demand.
