“Monthly Recurring Revenue.” The predictable total revenue generated by your business from all the active subscriptions in a particular month. It includes recurring charges from discounts, coupons, and recurring add-ons, but excludes one-time fees.
With MRR you can assess the present financial health of the business and project the future earnings based on the active subscriptions. To calculate MRR, multiply the number of monthly subscribers by the average revenue per user (ARPU).
