Why ARR growth matters

ARR growth tracks recurring momentum without mixing in one-time revenue. It's useful for planning and for comparing recurring scale over time when you keep the ARR definition consistent.

Three ways to express ARR growth

  • Period growth: (end ARR - start ARR) / start ARR.
  • CMGR: compounded monthly growth over the period (useful for comparisons across horizons).
  • Annualized growth (CAGR): converts the period change into an annualized rate.

Benchmarks and context

  • ARR growth is lumpy for enterprise deals; compare trailing averages.
  • CMGR is useful for short periods; annualized growth is better for longer horizons.
  • Segment by plan or ACV band to separate true momentum from mix shifts.

ARR growth QA checklist

  • Ensure start and end ARR snapshots use the same definition.
  • Exclude one-time fees and services from ARR.
  • Reconcile movements with the ARR waterfall to confirm drivers.

Common mistakes

  • Using inconsistent ARR definitions (services/one-time items included sometimes).
  • Comparing very short windows without adjusting for seasonality and deal timing.
  • Mixing run-rate metrics (ARR) with recognized revenue (accounting).

What to pair with ARR growth

  • Retention (NRR/GRR) so growth is durable, not leaky.
  • Payback and burn multiple so growth is cash-feasible.
  • Gross margin so growth quality improves profitability, not just top-line.
