What monthly recurring revenue tells you

Monthly recurring revenue, or MRR, normalizes subscription revenue into one monthly number. It gives SaaS founders a consistent baseline for measuring growth, forecasting cash inflows, comparing periods, and understanding whether new and expanding accounts are outpacing churn.

Only predictable recurring charges belong in MRR. Exclude setup fees, professional services, hardware sales, taxes, and other one-time revenue. Annual contracts should be divided by twelve so the metric remains comparable from month to month.

MRR formula(Active customers × monthly ARPA) + expansion MRR − churned MRR

How to calculate MRR correctly

Use a consistent cutoff date and revenue policy so changes reflect the business rather than accounting noise.

01

Normalize subscriptions

Convert weekly, quarterly, and annual recurring contracts into monthly values.

02

Separate movements

Track new, expansion, contraction, and churned MRR as different components.

03

Compare cohorts

Review MRR by plan, customer segment, geography, or acquisition channel.

MRR calculator FAQ

What is the difference between revenue and MRR?

Revenue includes every recognized sale, while MRR includes normalized recurring subscription charges only.

How do annual subscriptions affect MRR?

Divide the recurring annual contract value by twelve. A $1,200 annual subscription contributes $100 to MRR.

Can MRR be negative?

Total MRR should not be negative, but net new MRR can be negative when churn and contraction exceed new and expansion revenue.
