The SaaS LTV Calculator estimates the Customer Lifetime Value for your SaaS business using ARPU (Average Revenue Per User), monthly churn rate, and gross margin. It shows both gross profit LTV and net LTV, plus a health rating based on your LTV:CAC ratio.

Your data never leaves your device. No uploads, no servers, no tracking.
A good LTV is typically at least 3x your Customer Acquisition Cost (CAC). An LTV:CAC ratio of 3:1 or higher means your SaaS business is healthy and growing sustainably.
Churn rate is the percentage of customers who cancel each month. A 5% monthly churn means 5 out of every 100 customers leave per month, giving an average customer lifetime of 20 months.
Gross margin is revenue minus the cost of goods sold (COGS). In SaaS, COGS typically includes hosting, infrastructure, and support costs. Most SaaS businesses target 70-80% gross margins.
Focus on onboarding, customer success, and product improvements. Even reducing churn from 5% to 3% monthly can double your LTV. Regular check-ins and feature education significantly improve retention.
