Lean SaaS baseline
$120 ARPU, 80% margin, 4% monthly churn
A straightforward subscription model where churn and gross margin are the main drivers of lifetime value.
Result: A sub-4-month payback and an LTV:CAC comfortably above 3:1 usually signals room to scale more confidently.
Higher-ticket service
$450 revenue with lower margin but longer retention
Useful for agencies, coaching products, or B2B tools where revenue is stronger but margins are less software-like.
Result: Higher revenue can absorb a larger CAC, but the margin assumption still matters a lot.
Fast-churn ecommerce repeat buyer
$75 revenue, 55% margin, 9% churn
A retention-sensitive scenario where even modest churn improvements can change the economics materially.
Result: Retention pressure shortens lifetime fast, so LTV:CAC can look healthy or broken with only a few points of churn difference.
