Max MRR is the revenue ceiling where new MRR equals churned MRR.

How can I increase Max MRR?

Reduce churn, increase expansion revenue, and improve retention.

What is a good churn rate?

Many SaaS teams target under three percent monthly churn for steady growth.

Does NRR above 100 percent change the model?

Yes. Strong expansion revenue can break the ceiling and push growth higher.
