How it's calculated

MRR = paying customers × average monthly revenue per customer

Worked example
30 customers on a $99/mo plan = $2,970. 10 customers paying $900/yr, normalized to a monthly figure = $750. Total MRR = $3,720. ARR = $44,640.
What doesn't count as MRR
One-time setup fees, lifetime deals (LTDs), non-recurring consulting or implementation revenue, and one-off upsells. Mixing these in inflates MRR and makes your growth rate meaningless — a $10K lifetime deal is not $10K of recurring revenue.
FAQ

Common questions about MRR & ARR

Monthly Recurring Revenue — the predictable subscription revenue you can count on next month. It's paying customers × average monthly revenue per customer. It does not include one-time fees, setup charges, lifetime deals, or non-recurring consulting work.
