Why These Metrics Matter
Subscription businesses live and die by a handful of core metrics. Churn rate tells you how fast you're losing customers. Lifetime value shows what each customer is worth. Retention rate measures your ability to keep them. MRR churn and net revenue retention reveal whether your revenue base is growing or shrinking — independent of new sales.
The problem is that most teams track these metrics inconsistently, if at all. A 1% improvement in monthly churn can double customer lifetime value. A 5-point increase in NRR can mean the difference between a business that compounds and one that stalls.
These free calculators give you the numbers in seconds — no spreadsheets, no guesswork. Each includes industry benchmarks so you know where you stand and practical strategies to move the needle.
