Rozumienie Ekonomii Jednostkowej SaaS

Kluczowe metryki: LTV = ARPU × Marża brutto / Churn. CAC = Wydatki marketingowe / Nowi klienci. LTV/CAC ≥3 — zdrowy SaaS. Cel zwrotu CAC — poniżej 12 miesięcy.

FAQ

Jaki jest dobry stosunek LTV/CAC dla SaaS?

Zdrowy stosunek LTV/CAC to 3:1 lub wyżej. Poniżej 3:1 koszt pozyskania jest zbyt wysoki. Powyżej 5:1 może wskazywać na niedoinwestowanie w wzrost.
