What Is Customer Lifetime Value (LTV)?

Customer lifetime value (LTV) is the total revenue or profit a customer brings over the life of the relationship. It sets the ceiling on what you can afford to spend to acquire them.

Why LTV matters

LTV tells you how much a customer is worth, which tells you how much you can invest to win and keep them.

Businesses with high LTV can afford more aggressive acquisition; low-LTV models must acquire cheaply.

How to think about LTV

At its simplest, LTV combines average revenue, margin, and how long customers stay. Retention is a huge lever.

LTV and CAC together

A healthy ratio of LTV to CAC is the core signal of a sustainable growth model.

Key takeaways

  • LTV is a customer's total value over time
  • It sets your acquisition budget ceiling
  • Retention strongly drives LTV
  • Judge LTV against CAC for sustainability

FAQ

Common questions.

How is LTV calculated?

At its simplest, average revenue times margin times average customer lifespan — retention is a major lever.

What is a healthy LTV-to-CAC ratio?

It varies by model, but the value earned should comfortably exceed the cost to acquire, within a reasonable payback window.
