The monthly equivalent of ARR, computed as recurring revenue commitments normalised to a one-month basis. MRR is the operative metric for high-velocity self-service subscription businesses where the monthly billing rhythm is the natural unit of measurement. The federation requires MRR to be reported with the same inclusion rules as ARR, plus monthly net new MRR, expansion MRR, contraction MRR, and churn MRR broken out under UFMS-001:3.2. The MRR roll-forward is reconciled to the customer record.
A SaaS metrics coinage of the 2000s; the monthly framing reflects the operational cadence of self-service subscription businesses.
Federation members publishing MRR break out the monthly roll-forward components and reconcile to the customer record. Methodology consistency is verified at audit. The MRR trend feeds the cohort retention analysis under MEV-Annex:4.1.
