Assumptions and estimates

  • Simplified recurring-customer gross-profit LTV assumes constant revenue, margin and monthly churn; excludes discounting, expansion and retention costs. No universal ratio guarantees business health.
  • Method: CAC = acquisition spend ÷ new customers. Gross-profit LTV = monthly revenue × gross margin × estimated lifetime.
  • Constant churn and margin are assumptions. The ratio is a diagnostic, not a guarantee of a healthy business.
