Breaking down MRR
MRR (Monthly Recurring Revenue) is the predictable revenue your SaaS business generates each month. Tracking the components — new, expansion, churned, and reactivation — helps you understand where your growth is coming from and where you are losing revenue.
Net new MRR (new + expansion + reactivation - churned) is the key growth metric. A healthy SaaS business grows net new MRR by at least 10-20% month over month in the early stages.
