FAQ
What is MRR?
Monthly Recurring Revenue. Add starting MRR + new MRR + expansion MRR, subtract churned MRR + contraction MRR.
Good LTV:CAC ratio?
3:1 or higher is healthy. Below 1:1 is unsustainable.
What is the SaaS Quick Ratio?
Compares new + expansion MRR to churned + contraction MRR. Above 4 is very healthy.
How is LTV calculated?
ARPU × Average Customer Lifespan × Gross Margin. Average lifespan = 1 / monthly churn rate.
What is NRR?
Net Revenue Retention. Above 100% means existing customers grow faster than you lose them.
Healthy CAC payback?
