Frequently Asked Questions
What is MRR?
MRR (Monthly Recurring Revenue) is the predictable monthly revenue a SaaS or subscription business earns from active subscribers. It excludes one-time payments and is the primary health metric for subscription businesses. MRR = sum of (plan price × number of customers) across all active plans.
What is the difference between MRR and ARR?
MRR is your monthly recurring revenue snapshot. ARR (Annual Recurring Revenue) is simply MRR × 12 - it annualises the figure for easier comparison with annual contracts, investor benchmarks, and year-over-year growth metrics. ARR does not mean you have 12 months of revenue in the bank; it is a rate, not a balance.
What is net MRR?
Net MRR accounts for both expansion (new customers and upgrades) and contraction (churn and downgrades). It shows whether your revenue base is actually growing. Net New MRR = New MRR + Expansion MRR - Churned MRR. A healthy SaaS business has positive net MRR every month.
What is a good MRR churn rate?
For SaaS, a monthly churn rate below 2% is considered good. Under 1% is excellent. Enterprise SaaS typically achieves sub-0.5% churn due to longer contracts and higher switching costs. High churn (5%+) means you are losing customers faster than you can acquire them, which makes sustainable growth very difficult.
