Ehsan's Insight
LTV:CAC ratio is the most commonly cited SaaS metric and the most commonly miscalculated. The standard benchmark (3:1 is good, 5:1 is great) assumes correct LTV and fully-loaded CAC calculations. Most companies overestimate LTV (by using revenue instead of gross profit, ignoring discounts, or assuming infinite lifetime) and underestimate CAC (by excluding sales salaries, marketing tools, and content costs). Correct the calculation: use gross-margin-adjusted LTV with cohort-based churn curves, and fully-loaded CAC including all sales and marketing costs. The "healthy" 3:1 ratio often becomes 1.5:1 after these corrections — revealing that the business is not yet ready to scale.
