Churn quietly decides whether you grow

This MRR calculator turns three numbers - customers, average revenue per user, and monthly churn - into the metrics investors and founders actually run on: MRR, ARR, how many customers and how much revenue you lose every single month.

The projections are deliberately honest. With no new customers added, churn compounds, so you can see exactly where MRR lands after 6 and 12 months. That gap is what your sales and onboarding have to beat just to stand still - and why a point or two of churn reduction beats almost any marketing spend.

How is MRR calculated?

Monthly recurring revenue is your paying customer count multiplied by your average revenue per user (ARPU) per month. ARR is simply MRR multiplied by 12.

What is a good churn rate for SaaS?

For small and mid-market SaaS, roughly 3 to 5 percent monthly churn is common, while best-in-class companies aim below 2 percent. Even one point of churn compounds heavily over a year, which is why the 6 and 12 month projections matter.
