Per customerHow this works & what it assumes
The chain. Leads come from spend / CPL. Each stage multiplies by its conversion rate, so conversions land at leads * lead-to-booking * show rate * close rate. Revenue is conversions multiplied by the per-customer value for each window.
A conversion is a customer. The funnel counts conversions because not every business closes a "customer" — yours may be clients, patients, members, or signed contracts, and the booking may be a call, a demo, a consult, or a site visit. Everything downstream — CAC, LTV:CAC, revenue per customer — keeps the word customer, because those are the standard names for those metrics. Both words mean the same person.
Revenue windows are cumulative, not additive. The 90-day figure includes the first 30 days rather than stacking on top of it, and lifetime value includes everything.
Profit here is gross of delivery. Every profit figure is revenue minus ad spend only. It does not subtract fulfilment, sales commission, payroll, software, or platform fees — your true margin will be lower.
These are steady-state monthly estimates. The model assumes rates hold as you scale. In practice CPL rises as you push budget into colder audiences, so higher spend scenarios skew optimistic.
Projections are estimates based on the inputs above and are not a guarantee of results. Actual performance varies with offer, creative, audience, seasonality, and sales execution.
