Frequently asked questions

What is MRR?

MRR stands for Monthly Recurring Revenue, the predictable revenue a business earns each month from subscriptions or recurring payments.

How is ARPU calculated?

ARPU is total revenue divided by the number of customers in a given period. For MRR, use the average monthly revenue per customer.

Should I include one-time fees in MRR?

No, MRR should only include recurring revenue. One-time fees are excluded to keep the metric predictable.
