ARR vs MRR

Published by 4NLab · Updated · Our methods

ARR and MRR describe the recurring subscription base on different time scales. Under this site’s run-rate convention, ARR is exactly twelve times MRR. The choice is mainly about reporting context; neither figure tells you how much cash has been collected or how much revenue was earned over the past year.

Key differences

QuestionARRMRR
What does it express?The recurring base on an annual scale at a reporting date.The normalized monthly recurring base at a reporting date.
When is it useful?Discussing company scale and annualized changes.Explaining monthly changes from new business, expansion, contraction, and churn.
How does annual billing enter?As an annualized recurring amount, not the full multi-year booking.Spread over the subscription’s service months, not concentrated in the payment month.

One scenario, two measures

Hypothetical worked scenario

A fictional business has 50 monthly accounts paying $200 and 10 annual accounts paying $2,400. It collects a $5,000 one-time setup fee in the same month.

MRR = (50 × $200) + (10 × $2,400 ÷ 12) = $12,000. ARR = $12,000 × 12 = $144,000. The setup fee is excluded from both.

If one annual customer renews early, the cash balance changes on the payment date, but MRR and ARR need not change. If a customer upgrades by $100 per month, MRR rises by $100 and ARR by $1,200.

Which should you use?

  • Use MRR in a monthly operating review with a movement bridge. It makes the size of each upgrade or cancellation easier to trace back to the subscription ledger.
  • Use ARR when communicating the annual scale of the same recurring base. Show the date and definition so a reader does not mistake an exit rate for revenue earned during the year.
  • When planning hiring or spending, add a separate cash forecast. Converting MRR to ARR supplies no new information about payment timing or renewal probability.

Where comparisons can mislead

  • If a company reports committed ARR including future starts, reconcile that policy before comparing it with current MRR × 12.
  • Never multiply a multi-year total contract value by twelve. Normalize the recurring service schedule first.
