FAQ

Häufige Fragen

Why does LTV:CAC matter?

It tells you whether growth is actually compounding or just buying short-term revenue.

Is 3:1 always the right goal?

No. Some businesses can scale profitably below 3:1 if payback is fast and margins are strong.

Should I use gross or net LTV?

Use the version that best matches your margin structure and decision process, and stay consistent.
