CMRR (Committed MRR)
MRR adjusted for what you already know is coming — signed contracts not yet live, and churn already given notice.
What is it?
Committed MRR is headline MRR adjusted for the future you already know about: add signed contracts that haven't gone live yet, subtract customers who have given notice or whose non-renewal is confirmed. It converts MRR from a snapshot of the present into the most defensible forecast of the near future.
The gap between MRR and CMRR is information. CMRR below MRR means known churn outweighs signed backlog — the headline number is coasting on revenue that has already announced its departure. CMRR above MRR means booked momentum the snapshot hasn't caught up with.
How to calculate?
Start with current MRR, add the monthly value of signed-but-not-live contracts, and subtract the MRR of every subscription with a known end: notices given, non-renewals confirmed, downgrades scheduled. A $25,000 MRR with $500 of signed backlog and $3,000 of noticed churn is a $22,500 CMRR.
The discipline is in the word committed: only contractual facts count. Pipeline deals at 90% and at-risk accounts the CSM worries about belong in a forecast, not in CMRR — the metric's whole value is that nothing in it is a judgement call.
When to use CMRR over MRR?
Plan spending against CMRR, report growth against MRR. Hiring plans and cash models built on headline MRR quietly assume the noticed churn won't happen; CMRR removes the wishful thinking. Enterprise businesses with long notice periods and delayed go-lives get the most from it — the same mechanics that make their MRR stable also make it stale.
CMRR pairs naturally with durable MRR: durable MRR discounts the base statistically by expected churn, CMRR adjusts it contractually by known churn. When the two tell different stories, the difference is churn you should have seen coming.
