Definition

New MRR is recurring revenue added from brand-new customers in a period (excluding expansions from existing customers).

Example

If you close 20 new customers at $500 MRR each, new MRR is $10,000.

How to use it

  • Use New MRR to measure new customer acquisition output.
  • Segment by channel and plan to learn where new customers stick.
  • Separate reactivations from true new logos for clarity.
  • Track new MRR with payback to see if growth is cash-feasible.

Common mistakes

  • Counting expansion or upgrades as new MRR.
  • Mixing one-time fees with recurring revenue.
  • Including reactivations without labeling them separately.
  • Counting full contract value when revenue ramps over time.

Measured as

Measure New MRR on the same customer segment, time window, and revenue basis each time you review it.

Misused when

  • Counting expansion or upgrades as new MRR.
  • Mixing one-time fees with recurring revenue.

Operator takeaway

  • Use New MRR to measure new customer acquisition output.
  • Segment by channel and plan to learn where new customers stick.
  • Separate reactivations from true new logos for clarity.
  • Keep New MRR consistent by cohort, segment, and period before you use it as a decision signal in planning or reporting.
  • Interpret the metric alongside retention, margin, or payback so one ratio does not hide the real operating trade-off.
