What Is MRR and How to Calculate It Correctly

MRR (Monthly Recurring Revenue) is the normalized monthly revenue from all active subscriptions. It is the single most important health metric for any subscription business — and also one of the most frequently miscalculated.

The basic formula

MRR = number of paying customers × average revenue per user per month. For annual plans, divide the annual charge by 12 and count that as one month of MRR. Never count a full annual payment as MRR in the month it is received.

Common calculation mistakes

• Including one-time fees — setup fees, consulting, one-time purchases are not MRR
• Counting trial users — if they have not paid, they are not contributing to MRR
• Forgetting to subtract churn — MRR is a net figure, not gross
• Using cash received instead of earned revenue — an annual plan paid upfront is 1/12 per month

MRR components to track separately

Break your MRR into new MRR (from new customers), expansion MRR (upgrades), contraction MRR (downgrades), and churned MRR (cancellations). This breakdown tells you far more about your business than a single top-line number.

When your MRR is pulled directly from your payment processor and verified by a neutral source, it carries significantly more weight with buyers, investors, and partners than a self-reported figure.
