Committed Monthly Recurring Revenue (CMRR)

Committed monthly recurring revenue, or CMRR, is your current recurring revenue adjusted for changes you already know are coming. You take today's MRR, add signed contracts that have not yet started billing, and subtract revenue from customers who have given notice to cancel or downgrade. The result is a forward-looking figure that reflects what your recurring revenue will actually be once known events play out.

Plain MRR only shows where you are right now; CMRR shows where you are heading based on commitments already in hand. For a founder this is a sharper planning number. It stops you from celebrating a strong month when two big accounts have already given notice, and it lets you count a signed annual deal that starts next quarter. Used well, CMRR gives you a more honest base for forecasting cash, runway and hiring, because it builds in the changes you can already see rather than waiting for them to hit the books.
