MRR and ARR, the subscription vitals

Monthly recurring revenue is subscribers times average revenue per user. Annual recurring revenue is the yearly run rate — MRR times 12. Together they're the clearest read on a subscription business's health.

MRR = subscribers × ARPU · ARR = MRR × 12

Quick FAQ

Does ARR account for churn?

Not here — this is a run-rate snapshot. Real ARR movement comes from new, expansion, contraction, and churned revenue over the year.

How do I grow MRR?

Add subscribers, raise ARPU (upsells, tiers), or cut churn. Reducing churn compounds because every retained customer keeps paying.
