MRR (Monthly Recurring Revenue)
Monthly Recurring Revenue (MRR) is the normalized monthly value of all active subscription revenue, providing a real-time view of a SaaS business's revenue run rate. MRR standardizes subscriptions of varying lengths and billing frequencies into a consistent monthly figure — annual contracts are divided by 12, quarterly by 3. MRR is the operational heartbeat of subscription businesses, used for monthly performance tracking, churn detection, and short-term forecasting where ARR is too coarse a measure.
Key Details
- Formula: MRR = sum of monthly-normalized values of all active subscriptions; annual contracts contribute (annual value / 12) per month
- MRR movement categories: new MRR (new customers), expansion MRR (upgrades/add-ons), contraction MRR (downgrades), and churned MRR (cancellations)
- Net MRR growth rate = (new + expansion - contraction - churn) / beginning MRR — the single metric that shows business momentum
- MRR differs from recognized revenue: MRR is a management metric; recognized revenue follows ASC 606 rules with potential timing differences
- Quick ratio = (new MRR + expansion MRR) / (contraction MRR + churned MRR) — measures growth efficiency; >4 indicates healthy SaaS
- MRR reconciliation compares CRM/billing system MRR calculations against actual invoiced amounts to catch pricing errors and missed cancellations
- Cohort-based MRR analysis tracks revenue retention by customer signup month, revealing long-term retention trends invisible in aggregate numbers
