Monthly recurring revenue (MRR)

Monthly recurring revenue (MRR) is the normalized, predictable subscription revenue a business expects each month. Annual and multi-month plans are divided down to a monthly figure so the run rate is comparable. MRR is decomposed into new, expansion, contraction, and churned components, and it deliberately excludes one-off and usage-based charges — so it is a run-rate concept, not booked or recognized revenue.

What this means

MRR is the sum of each active subscription's monthly-normalized value. An annual plan billed once is counted as one-twelfth per month; a quarterly plan as one-third. The result is a smooth monthly run rate that is comparable period to period even when customers pay on different cadences. MRR is a SaaS planning metric, not a GAAP figure, and differs from recognized revenue.

The MRR movement breakdown

Net change in MRR is conventionally split into components: new MRR (from new customers), expansion MRR (upgrades, seat additions, cross-sells), contraction MRR (downgrades), and churned MRR (cancellations). Net new MRR = new + expansion − contraction − churn. This decomposition is the point of the metric: a stable total can mask strong acquisition offset by heavy churn, and only the components show it. MRR usually excludes one-time fees and pure usage charges, which are not recurring.

How it appears in analytics and logs

An MRR figure summarizes recurring monthly revenue at a point in time. A flat headline MRR can hide large offsetting movements — new and expansion gains cancelling contraction and churn — which the component breakdown reveals.

Diagnostic use case

Use MRR as a normalized monthly run-rate for subscription revenue, and track its new/expansion/contraction/churn components to see what is driving change.

WebmasterID measures the on-site behavior of subscribers via first-party events, so signup, upgrade, and cancellation actions feeding an MRR model are captured without third-party cookies.

Privacy and accuracy notes

MRR is an aggregate revenue concept; it needs no personal identifiers. It is an educational definition, not accounting or legal advice.
