Calculate the net recurring-revenue movement from new business and expansion after subtracting churn and contraction, then reconcile the result to ending MRR.
Classify each recurring-revenue movement once and keep every amount on the same normalized MRR basis. This calculator uses New + Expansion - Churn - Contraction; if your system reports Reactivation MRR separately, reconcile it under your documented policy.
Net New MRR summarizes the recurring-revenue movement created by new business and expansion after churn and contraction. A positive result means included gains exceeded included losses, but the movement mix still matters: strong acquisition can mask high churn, and strong expansion can offset weak new-logo growth.
Use Ending MRR = Starting MRR + Net New MRR as a reconciliation check under the same four-part convention. If your reporting stack tracks Reactivation MRR, FX adjustments or other movement types separately, document that policy before comparing the calculator with a billing or analytics dashboard.
Net New MRR is a SaaS movement metric for explaining how recurring revenue changed during a period. Keep the opening MRR balance and every movement on one normalized recurring-revenue basis so the bridge can be reproduced from billing, finance or subscription analytics data.
The SolveIndex convention is Net New MRR = New MRR + Expansion MRR - Churned MRR - Contraction MRR; Ending MRR = Starting MRR + Net New MRR; MRR Growth Rate = Net New MRR / Starting MRR x 100. New business means newly paying customers, while expansion means existing active customers paying more.
Use the gains and losses outputs to diagnose the headline result. Two companies can report the same Net New MRR with very different operating quality if one has low churn and steady expansion while the other replaces large recurring-revenue losses with expensive acquisition.
Movement definitions matter. ChartMogul-style reporting can track Reactivation MRR as a separate movement, while other Net New MRR formulas use only New, Expansion, Churn and Contraction. Apply one documented convention consistently rather than mixing categories from different systems.
