Understanding Monthly Recurring Revenue (MRR)
Monthly Recurring Revenue (MRR) is the single most vital health metric for software-as-a-service (SaaS) and subscription businesses. Measuring your MRR breakdown allows founders and investors to track expansion, churn rates, and unit economics compounding.
Frequently Asked Questions
What is Monthly Recurring Revenue (MRR)?
MRR is the predictable total revenue a subscription-based SaaS business expects to receive every single month.
What is Net New MRR?
Net New MRR measures month-over-month recurring revenue growth. The formula is: Net New MRR = New MRR + Expansion MRR + Reactivation MRR - Contraction MRR - Churned MRR.
What is Expansion MRR?
Expansion MRR is additional recurring revenue generated from existing customers upgrading their subscription plans or purchasing add-ons.
Why is Churn MRR critical for SaaS startups?
Churn MRR represents lost recurring revenue from canceled subscriptions. High churn erodes customer acquisition ROI and limits long-term compounding growth.
How do annual subscriptions factor into MRR calculations?
For annual upfront subscriptions, divide the total annual contract value (ACV) by 12 to calculate the monthly MRR contribution.
