Consider a SaaS company with the following metrics: Average Revenue Per User (ARPU) of $100 per month, gross margin of 80%, and average customer lifespan of 24 months. Using the gross margin-adjusted method:
LTV = (Monthly ARPU × Gross Margin %) × Average Customer Lifespan LTV = ($100 × 0.80) × 24 months = $80 × 24 = $1,920
This calculation reveals that each customer generates $1,920 in lifetime value after accounting for direct costs. If the company's CAC is $600, the LTV:CAC ratio would be 3.2:1, indicating healthy unit economics with reasonable payback periods.
