LTV:CAC = Customer Lifetime Value / Customer Acquisition Cost

If a customer is worth $240 over time and costs $80 to acquire, the ratio is 3:1. That might be healthy if payback is also fast.

FAQ

Preguntas frecuentes

Is 3:1 always the right target?

No. The right ratio depends on margin, payback speed, and growth stage.

Does LTV:CAC replace ROAS?

No. ROAS is the short-term revenue view; LTV:CAC is the longer-term economics view.

Why is payback important?

Because a healthy ratio can still be risky if the cash comes back too slowly.
