Why monthly recurring revenue (MRR) matters to a first-time founder
MRR shows the predictable revenue base your business is building, separate from one-off fees and lumpy project income. Investors use it to judge growth and to value subscription companies, and you use it to plan hiring and spending against income you can expect next month. If you mix in one-off payments or unpaid trials, the figure looks healthier than it is, and decisions based on it can shorten your runway.
Examples of monthly recurring revenue (MRR)
Forty freelancers pay €20 a month. MRR is €800. If ten leave, it falls to €600, even if a one-off setup fee arrived the same week. The setup fee is cash and it may be revenue. It is not monthly recurring revenue, because it will not happen again next month by itself.
Common misunderstanding
People multiply a good month by twelve and call it the annual figure, including trials, overdue invoices, and one-off projects. Or they think MRR and ARR are different businesses. They are the same subscriptions, seen by the month or by the year. Churn changes both.
When to use it
Track MRR from your first paying subscriber. Each month, break the change into new MRR from new customers, expansion from upgrades, and churned MRR from cancellations and downgrades. The total alone can hide a leak: €2,000 of new MRR looks good until you see €1,800 of existing MRR cancelled in the same month. Count annual plans as one twelfth per month, and exclude setup fees, trials and overdue invoices.
