How to use this calculator
Enter subscribers, ARPU, monthly churn and new subscribers per month. The result shows current MRR/ARR and a 12-month projection, plus the ARR you'd gain by cutting churn.
Why churn dominates SaaS growth
Because churn compounds, retention improvements often beat acquisition spend on ROI. The scenario comparison makes the trade-off explicit.
Sources
Benchmark medians are sourced from public SaaS industry reports including ChartMogul and OpenView, versioned in the platform configuration.
Frequently asked questions
How is MRR calculated?▾
MRR = active subscribers × ARPU. ARR = MRR × 12. The 12-month projection compounds new subscribers minus churn each month.
How does churn affect ARR?▾
Churn compounds monthly, so even a 2-point reduction can add significant ARR over a year — the calculator shows the exact delta.
What is a healthy churn rate?▾
B2B SaaS medians sit near 5% monthly for SMB and far lower for enterprise. The benchmark bar compares yours to the median.
