The formula
Lifetime in months = 1 / Monthly churn rate; Gross-profit LTV = Monthly revenue × Gross margin × Lifetime. Convert percentages to decimals.
Worked example
₹1,500 monthly revenue at 80% margin and 5% monthly churn gives a modeled lifetime of 20 months and ₹24,000 LTV, or ₹18,000 after ₹6,000 acquisition cost.
