MRR — Monthly Recurring Revenue
What it actually means
Monthly Recurring Revenue is the foundational SaaS metric. Calculated as the sum of all active subscription rates normalized to monthly. Annual subscriptions divided by 12. Quarterly divided by 3. One-time setup fees explicitly EXCLUDED — MRR is the recurring portion only. MRR breaks down into: New MRR (this month's new customers), Expansion MRR (existing customers upgrading), Churn MRR (customers canceling), Contraction MRR (existing customers downgrading). Net New MRR = New + Expansion - Churn - Contraction.
MRR ≠ revenue. Revenue includes one-time setup fees, professional services, etc. MRR is specifically the recurring subscription rate. Cadence Founding Coach at $39/mo + $199 setup contributes $39 to MRR (the setup is one-time revenue but not MRR). At 25 founding coaches, Cadence MRR = $975/mo from founding tier alone.
