Plain definition
Monthly recurring revenue, or MRR, is the normalised monthly value of active recurring subscription commitments. It is usually built from subscription records, adjusted for recurring upgrades, downgrades, and cancellations. MRR is a run-rate metric: it is not automatically recognised revenue under accounting rules, cash collected, bookings, or the total contract value signed in the month.
A useful MRR bridge separates starting MRR, new subscriptions, expansion from existing customers, contraction, and churn. It should use consistent rules for discounts, usage-based charges, annual contracts, pauses, refunds, and the date on which a subscription becomes active.
Illustrative example
Monetary examples use Saudi riyals (SAR). The same principles apply in other currencies.
Suppose a company begins a month with of MRR. Existing customers add of recurring subscriptions, while cancellations remove . Ending MRR is . The bridge describes the active monthly run rate; it does not mean was collected in cash or recognised as revenue in that month.
Management can see whether growth came from new logos or existing customers, then investigate retention and sales action instead of relying on an ending total alone.

Do not annualise non-recurring setup fees, one-time services, or uncertain usage estimates into MRR.
Why it matters
MRR gives a timely view of subscription momentum, but poor definitions can make it rise while customer economics or cash deteriorate. A transparent bridge makes the metric auditable.
Practical consequence
Document which contracts and adjustments qualify as recurring, the monthly normalisation method, and the active-date rule. Reconcile the MRR bridge to subscription records, preserve movements by customer cohort, and compare the metric with invoicing, cash, and revenue recognition without treating them as interchangeable.
