ARR Calculator

MRR × 12—the shorthand annualized run rate investors ask for in casual updates.

Overview

Use when MRR is already trustworthy. One blowout month times twelve prints a heroic ARR—note volatility verbally when you share it.

When to use this calculator

Rule of thumb

Twelve × one frothy month of MRR prints a heroic ARR. Label volatile months when you quote it.

Terms used in this calculator

ARR
Often ARR ≈ twelve times MRR shown as a monthly run rate for planning—not the same wording finance uses on official revenue recognition.
MRR
Monthly recurring revenue: paying subscribers times the recurring monthly revenue you attach to each after any annual-to-monthly split you use.

How to interpret this result

Annualized run rate from MRR × 12—common in SaaS conversations.

Not GAAP revenue recognition and not a forecast unless MRR is stable.

Avoid annualizing a single volatile month unless you label it.

Common mistakes

  • Calling ARR “GAAP revenue” without adjustments.
  • Multiplying a non-representative single-month MRR by 12.
  • Ignoring churn occurring within the month before annualizing.

What to do next

Return to monthly MRR inputs when ARR shocks you—annualization hides monthly volatility.

How to improve this result

  • Smooth ARR quotes with three-month MRR averages when seasonality is real.
  • Strip one-time services from ARR stories unless finance truly treats them as recurring.
  • Pair ARR growth with GRR so churn does not hide inside the headline.
