What is customer lifetime value?

LTV is the total revenue a customer generates over their entire relationship with your business. For SaaS, it equals ARPU divided by monthly churn rate.

What is a good LTV-to-CAC ratio?

A 3:1 ratio is the benchmark. If your LTV is $300, your CAC should be under $100. Below 1:1 means you are losing money on every customer.

How do I increase LTV?

Reduce churn, increase ARPU through upselling, and extend customer lifetime through better onboarding and support.
