Definition

MRR growth rate measures how MRR changed between two points in time. It can be expressed as period growth, CMGR, or annualized growth.

Formula

MRR growth (period) = (end MRR - start MRR) / start MRR

Example

Start MRR $200k and end MRR $230k in 3 months: period growth is 15%.

How to use it

  • Use CMGR to compare growth across different horizons.
  • Use an MRR waterfall to explain drivers (new vs expansion vs churn).
  • Pair growth with retention (NRR/GRR) and payback to judge quality.
  • Track by segment to separate enterprise deal timing from core momentum.

Common mistakes

  • Comparing short periods without adjusting for seasonality or deal timing.
  • Mixing run-rate MRR with recognized revenue in growth reports.

Measured as

MRR growth (period) = (end MRR - start MRR) / start MRR

Misused when

  • Comparing short periods without adjusting for seasonality or deal timing.
  • Mixing run-rate MRR with recognized revenue in growth reports.

Operator takeaway

  • Use CMGR to compare growth across different horizons.
  • Use an MRR waterfall to explain drivers (new vs expansion vs churn).
  • Pair growth with retention (NRR/GRR) and payback to judge quality.
  • Keep MRR Growth Rate 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.
