SaaS LTV:CAC Ratio Calculator formula
Estimated LTV = Monthly ARPA × Gross Margin ÷ Monthly Churn Rate; LTV:CAC = LTV ÷ CAC
Example
$150 ARPA at 80% gross margin and 3% monthly churn produces a simplified LTV estimate of $4,000 before comparing it with CAC.
How to use the result
This is a simplified steady-state LTV model. Cohort retention, expansion, contracts, onboarding cost, and changing churn can materially alter true lifetime economics.
