What is CLTV (Customer Lifetime Value) in SaaS?
Customer Lifetime Value (CLTV) is the total revenue a SaaS company can expect to earn from a customer over the entire duration of their relationship.
It helps measure the long-term value of acquiring and retaining customers and is critical for growth planning and financial forecasting.
Why Does CLTV Matter for SaaS Companies?
CLTV is important because it:
- Determines how much can be spent to acquire a customer (CAC)
- Helps identify profitable customer segments
- Guides marketing, sales, and retention strategies
- Supports revenue forecasting and business valuation
- Measures the effectiveness of upsell, cross-sell, and retention programs
A higher CLTV indicates strong customer retention and revenue potential, while a low CLTV may signal issues with engagement or pricing.
How is CLTV Calculated in SaaS?
The basic formula for Customer Lifetime Value is:
Example:
- ARPU: $100/month
- Gross Margin: 80%
- Average Customer Lifetime: 24 months
- CLTV = 100 × 0.8 × 24 = $1,920
This means each customer is expected to generate $1,920 in gross profit over their lifetime.
What Factors Influence CLTV in SaaS?
- Subscription pricing and plan tiers
- Customer retention and churn rates
- Upsell and cross-sell effectiveness

How Can SaaS Companies Increase CLTV?

What Are Common Mistakes in Calculating CLTV?
