Understanding MRR and ARR
What it does
Calculates your total Monthly Recurring Revenue (MRR), net new MRR from new customers and expansions minus churn, month-over-month growth rate, and annualized run rate (ARR).
Why it matters
MRR is the single most important metric for SaaS businesses. It reflects predictable, recurring revenue and is a leading indicator of company health and growth trajectory.
Definition
Net New MRR = New MRR + Expansion MRR - Churned MRR. Total MRR = Previous Month MRR + Net New MRR. ARR = MRR × 12.
Assumptions
- •MRR includes only contracted recurring revenue, not one-time fees.
- •Expansion MRR includes upsells, add-ons, and seat expansions.
- •Churn is calculated at the revenue level, not customer count.
How to interpret your results
10% MoM growth is a strong SaaS target. 5-7% is healthy. Below 3% suggests slow growth. Strong companies maintain 10-20%+ growth in early stages, then normalize to 3-7% as they mature.
How to improve
Increase new MRR
Scale sales and marketing to acquire more customers. Each new customer adds predictable recurring revenue.
Expand existing customers
Upsell seat additions, premium tiers, or add-on features. Expansion MRR is often more efficient than new customer acquisition.
Reduce churn
Improve onboarding, support, and feature releases. A 1% reduction in churn rate can increase MRR growth by 2-3%.
