What is Net New MRR?

Net new MRR is the real change in your monthly recurring revenue in a period — new and expansion revenue minus contraction and churn. It shows whether you're actually growing.

Net new MRR = new + expansion − contraction − churned

How to read your result

  • New and expansion MRR add to the total; contraction and churn subtract.
  • A positive number means growth; negative means you're shrinking.
  • Expansion often matters more than new sales at scale.
  • Track the mix, not just the total, to see what's driving movement.
