Frequently Asked Questions

What is SaaS MRR?

Monthly Recurring Revenue — predictable subscription revenue billed monthly. MRR is the key metric for SaaS businesses. It excludes one-time fees, overage charges, and professional services. MRR growth rate is the #1 metric investors look at.

What is a good SaaS growth rate?

Rule of 40: Growth rate + Profit margin should exceed 40%. SaaS companies growing 40%+ annually often trade at premium valuations. 20-30% is healthy for post-PMF (product-market fit) companies.

What drives MRR growth?

New customer acquisition, expansion revenue (upgrades, seat expansion), and contraction reduction (minimizing churn). Net New MRR = New MRR + Expansion MRR - Churned MRR. Focus on all three levers.
