📖 What is MRR?
MRR (Monthly Recurring Revenue) is the most important financial metric in SaaS. Net New MRR = New Customer MRR + Expansion MRR - Contraction MRR - Churned MRR. Positive net new MRR means the business is growing. ARR (Annual Run Rate) = Net New MRR × 12, used to forecast annual revenue. Investors typically value SaaS companies at 10-20× ARR. Tracking these metrics helps identify growth drivers and potential risks before they become problems.
