MRR (Monthly Recurring Revenue) is the sum of all recurring monthly revenue from active subscriptions. It is the fundamental metric for measuring the health and growth of a subscription business.
MRR = New MRR + Expansion MRR − Churned MRR
ARR (annual) = MRR × 12
100 customers × $200/mo = MRR: $20,000
ARR = $20,000 × 12 = $240,000
