Ehsan's Insight
Most LTV calculations are dangerously wrong because they assume constant churn rate and no expansion revenue. Reality is messier: churn rate decreases over time (customers who survive the first 90 days are 3-5x less likely to churn), and expansion revenue (upsells, cross-sells) can increase ARPU 50-100% over a customer's lifetime. A cohort-based LTV that accounts for both effects can be 2-3x higher than a naive calculation. This matters enormously for CAC decisions: if your real LTV is $3,000 instead of $1,000, you can afford to spend $750 on acquisition instead of $250. Underestimating LTV is as dangerous as overestimating it — you underspend on growth and lose market share to competitors who calculated correctly.
