Understanding MRR and ARR
Monthly Recurring Revenue (MRR) is the predictable revenue your SaaS business generates each month from subscriptions. Annual Recurring Revenue (ARR) is MRR × 12. These are the most important metrics for subscription businesses because they show recurring, predictable income.
Why Churn Matters
Churn is the percentage of customers who cancel each month. Even a 5% monthly churn rate means you lose 60% of customers per year if not replaced. Best-in-class SaaS companies maintain monthly churn under 3%. Reducing churn from 5% to 3% can double your revenue in 3 years.
ARPU (Average Revenue Per User)
ARPU shows the average monthly revenue per customer. Increasing ARPU through upsells, cross-sells, or annual plans is often easier than acquiring new customers. Track ARPU by cohort to measure pricing power and customer value expansion.
