Common questions

Is ARR the same as annual revenue?

No. It's a run rate of current subscriptions; recognised revenue for the year can differ.

How do annual plans count?

Divide each annual fee by 12 for MRR first, or add annual fees directly to ARR. Check the formula, example, and limitations on this page before using the result for a real sales decision.

Include trials?

No — only paying recurring contracts. Check the formula, example, and limitations on this page before using the result for a real sales decision.
