Monthly Recurring Revenue (MRR) is predictable subscription revenue per month. It is customers times average revenue per user (ARPU) or the sum of all active subscriptions. Unlike one-time sales, MRR isolates recurring health and compounds with retention. Splitting MRR into new, expansion, contraction and churned reveals quality — flat MRR despite new sales means churn is eating growth, while expansion without new logos shows monetization strength.
To use the MRR Calculator, enter paying customers and ARPU or total subscription revenue. The tool instantly shows MRR, ARR (MRR×12), churned MRR and net new MRR. Adjust churned customers or expansion MRR to forecast next month. Example: 120 customers at $49 ARPU is $5,880 MRR; losing 5 customers ($245) but adding $300 expansion yields net +$55, or $5,935 MRR. Check the worked example and FAQs to avoid mixing one-time fees with recurring.
