How this calculation works
This calculator applies the stated mrr = number of customers * average revenue per account; net new mrr = new mrr + expansion mrr - churned mrr formula to the values entered above.

MRR Calculator FAQ
What is MRR?
MRR stands for monthly recurring revenue, a common way to track predictable subscription revenue.
What is net new MRR?
Net new MRR shows how recurring revenue changes after adding new, expansion, and churned MRR.
Do I need the optional fields?
No. They are only needed if you want the net new MRR result in addition to base MRR.
Can customer count or ARPA be negative?
No. The calculator prevents negative values because recurring revenue inputs cannot be negative.
