Frequently Asked Questions

• What is MRR? ▼
  Monthly Recurring Revenue (MRR) is the predictable monthly revenue from active subscriptions. Basic formula: MRR = Number of Customers × ARPU (Average Revenue Per User per month).
• What is Net New MRR? ▼
  Net New MRR = New MRR + Expansion MRR − Churned MRR − Contraction MRR. It shows how much your recurring revenue grew (or shrank) in a month.
• How is ARR different from MRR? ▼
  ARR (Annual Recurring Revenue) = MRR × 12. ARR is used for annual financial planning and investor reporting; MRR is used for monthly operational tracking.
• What is expansion MRR? ▼
  Expansion MRR is additional revenue from existing customers — upgrades, add-ons, and seat expansions. Healthy SaaS companies have expansion MRR that partially or fully offsets churn.
• What is a healthy MRR growth rate? ▼
  Early-stage startups often target 10–20% monthly MRR growth. At $1M ARR, 5–10% monthly is strong. At $10M+ ARR, 3–5% monthly (50–100%+ annually) is considered excellent.
