Definition

ARR (Annual Recurring Revenue) is the annualized run-rate of your recurring subscription revenue. It is a snapshot of current recurring momentum, not a promise of what you'll recognize over the next 12 months.

Formula

ARR = MRR * 12

Example

If your MRR is $200,000, your ARR is $2,400,000. With annual prepaid plans, cash can spike while ARR moves based on recurring run-rate.

Common mistakes

  • Treating ARR as recognized revenue for the next year.
  • Including one-time fees or services revenue in ARR.
  • Comparing bookings to ARR without normalizing one-time items and term length.

Why this matters

This term matters because small changes compound in SaaS metrics. Use consistent definitions by cohort and segment so you can diagnose retention, payback, and growth quality.

Practical checklist

  • Write a 1-line definition for "ARR (Annual Recurring Revenue)" that your team will use consistently.
  • Keep the time window consistent (weekly/monthly/quarterly) when comparing trends.
  • Segment results (channel/plan/cohort) before drawing big conclusions from blended averages.
  • Use a calculator that references this term (e.g., ARR Calculator) to sanity-check assumptions.
  • Read the related guide (e.g., Bookings vs ARR: what ARR means (and what it doesn't)) for context and common pitfalls.
