Monthly recurring revenue is the heartbeat of a subscription business, the predictable money that arrives every month. Here is the plain definition, the formula and the four moving parts that decide whether it grows.
MRR moves through four channels: new MRR from fresh customers, expansion MRR from upgrades, contraction MRR from downgrades and churned MRR from cancellations. Net new MRR is the sum of all four. Track them separately or a flat headline number can hide a business where heavy churn is quietly eating strong new sales.
The free MRR forecast tool projects how your monthly recurring revenue grows under different assumptions.
There is no good MRR number in the abstract, only a good growth rate and a healthy mix of the four components. A business adding plenty of new MRR while bleeding churned MRR is far weaker than its headline growth suggests, because the leak gets harder to outrun as the base grows.
The healthiest MRR growth comes from expansion as much as new sales. When expansion MRR outpaces contraction and churn, your base grows on its own, which is net revenue retention above 100 percent. That is the difference between filling a leaky bucket and compounding.
New customers who fit and stay are worth far more than logos that churn in a quarter. Quality of new MRR matters as much as quantity.
Upsells and seat growth add MRR with no acquisition cost. Pricing that grows with customer value is the cleanest engine of MRR growth.
Churned and contraction MRR drag the whole number down. Retention work protects the base and makes every other gain stick.
MRR is the predictable subscription money you can count on every month. It strips out one-off fees and services and normalises everything to a monthly figure, so an annual plan counts as one twelfth per month. It is the steady base that makes a subscription business predictable in a way project revenue never is.
Multiply your number of paying accounts by the average monthly revenue per account, with annual plans divided by 12 to get a true monthly run rate. Exclude one-time setup fees and professional services, since those are not recurring. The cleanest approach is to sum the normalised monthly value of every active subscription.
MRR moves through four parts: new MRR from fresh customers, expansion MRR from upgrades and seat growth, contraction MRR from downgrades and churned MRR from cancellations. The sum of all four is your net new MRR for the period. Tracking them separately shows whether growth is healthy or whether churn is hiding under strong new sales.
MRR is the monthly view and ARR is the annual one, so ARR is roughly MRR times 12. Teams selling monthly plans usually live in MRR, while those on annual contracts report ARR. They describe the same recurring revenue at different time scales and you convert between them by multiplying or dividing by 12.
Because MRR is meant to capture what is predictable and repeatable. Setup fees, one-off services and usage spikes do not recur, so including them inflates the figure and makes forecasting unreliable. Keeping MRR to pure recurring subscription revenue is what makes it a trustworthy base for growth, churn and forecasting metrics.
If new MRR is strong but the number barely moves, churn is the culprit. Book a 30-minute audit and we will trace where the MRR leaks. No sales sequence.
