Mastering SaaS Metrics: The MRR Guide

What is MRR?

Monthly Recurring Revenue (MRR) is the predictable total revenue generated by your business from all active subscriptions in a single month. It is the lifeblood of any SaaS company, providing clear visibility into financial health and scalability.

Formula for Growth

MRR = (ARPU) × (Paying Customers)

For high-growth teams, Net New MRR is the goal:
New + Expansion - Churned

Negative Churn

The holy grail of SaaS. Occurs when Expansion MRR from existing customers exceeds revenue lost from cancellations.
