Methodology and assumptions
Monthly gross profit m = revenue × gross margin. With monthly churn c and monthly discount r = (1 + annual rate)^(1/12) − 1, survival-discount factor q = (1 − c) ÷ (1 + r). LTV = m × (1 − q^H) ÷ (1 − q) for a horizon of H months, or m ÷ (1 − q) uncapped; with no discount this is the familiar m ÷ c. Average lifetime = 1 ÷ c. CAC payback = CAC ÷ m. This is a steady-state model, not a cohort forecast; zero churn with no cap has no finite LTV.
