MRR
Also called Monthly Recurring Revenue, ARR, and Annual Recurring Revenue
The predictable subscription revenue you can count on each month (MRR), or the same figure annualised (ARR). It strips out one-off payments to show the recurring core of the business.
Why it matters
For any subscription business, recurring revenue and how fast it grows is the headline number investors and you track. Its movements, new, expansion, churned, tell you exactly where growth is coming from and leaking out.
