What is Net New MRR?
The total change in Monthly Recurring Revenue over a period, combining new customer MRR, expansion MRR, contraction MRR, and churned MRR into a single growth metric.
Understanding the Details
Net New MRR shows the complete picture of MRR movement. It's calculated as: New MRR (from new customers) + Expansion MRR (upsells, cross-sells, added seats) - Contraction MRR (downgrades) - Churned MRR (cancellations). This single number tells you whether your recurring revenue base is growing or shrinking and by how much. Breaking it into components reveals what's driving growth or decline. If net new MRR is positive but declining, the components show whether you have a growth problem (less new MRR), a retention problem (more churn), or both. Tracking these components monthly creates the trend data needed for reliable forecasting and strategic planning.

Net new MRR is just new customer revenue. Actually, it includes expansion, contraction, and churn — the complete revenue picture.
