TL;DR
MRR is the sum of all active subscription fees normalized to a monthly basis at a point in time. MRR equals ARR divided by 12. One-time fees, professional services, and uncommitted usage are excluded. Net New MRR equals New plus Expansion minus Contraction minus Churn.
Definition
MRR is the heartbeat of an early-stage SaaS company. A founder who reads MRR every Monday morning sees the growth shape of the business in a way that no annual figure will provide. A 12,000 dollar MRR figure in January that becomes 18,000 dollars in March is a 50 percent jump in two months, and the team can feel the trajectory. For founders running outbound and closing deals month by month, MRR is the number that sets the tempo.
MRR is a point-in-time snapshot, not a trailing or forward-looking figure. If a company has 240,000 dollars in MRR on 31 March, that means the sum of all live, recurring subscription fees on that date equals 240,000 dollars. It is what the current subscriber base would generate over the next month if nothing changed.
What counts toward MRR: monthly subscription fees for the core product, recurring platform fees, committed usage minimums, recurring per-seat fees, and recurring add-on modules that auto-renew. What does not count: setup and implementation fees, professional services, training, hardware, one-time customizations, true variable usage with no commit, and any revenue from a contract not yet live.
How to calculate MRR
Take every active subscription on a single date, calculate the monthly value of each, and add them. Three subscription patterns produce three calculation rules.
- Monthly subscribers: contribute the monthly fee as it stands. A customer paying 1,200 dollars per month contributes 1,200 dollars to MRR.
- Annual subscribers: contribute the annual contract value divided by 12. A customer paying 60,000 dollars per year contributes 5,000 dollars in MRR.
- Multi-year contracts: contribute the annualized value divided by 12. A 300,000 dollar three-year contract contributes 8,333 dollars to MRR.
For consumption-based pricing, only the committed minimum counts toward MRR. Variable overage is tracked separately as Consumption Revenue. The relationship between ARPA and MRR matters for operating decisions: ARPA multiplied by customer count equals MRR. When the two numbers do not reconcile, the cause is almost always a mix of subscription terms or definitional drift between systems.
MRR components
MRR movement during a month decomposes into four components. Each has a separate owner, and reporting them separately is what makes coaching and forecasting possible.
New MRR
MRR added from new logos closed in the month. Owner: new-business AE team.
Expansion MRR
MRR added from existing customers through upsells, cross-sells, or seat expansions. Owner: account management or CS.
Contraction MRR
MRR lost from existing customers who downgraded but did not churn entirely. Seat reductions, tier downgrades, or removed add-ons.
Churn MRR
MRR lost from customers who fully cancelled. Net New MRR equals New plus Expansion minus Contraction minus Churn.
MRR vs ARR
MRR is the operating metric for early-stage SaaS where most customers pay monthly. A team with 850 monthly subscribers each paying an average of 240 dollars per month has 204,000 dollars in MRR and 2.45 million dollars in ARR. As the team moves up market and contracts shift to annual, MRR becomes a less useful operating signal and ARR takes over as the headline metric on the board pack.
GAAP revenue is the accounting figure on the income statement. It includes services, one-time setup, training, and any other revenue the company recognized during the period under ASC 606 rules. MRR is always different from recognized revenue at a given point because of timing differences and the exclusion of services. Show both, with the reconciliation between them.

Frequently asked questions
What does MRR stand for?
MRR stands for Monthly Recurring Revenue. It is the predictable subscription revenue a SaaS business generates each month, normalized to a 30-day basis. MRR includes only recurring contractual subscription fees and excludes one-time charges such as setup, professional services, and hardware.
How is MRR calculated?
MRR is the sum of every active subscriber's monthly subscription fee at a point in time. For an annual subscriber paying 12,000 dollars per year, the MRR contribution is 1,000 dollars per month. For a quarterly subscriber paying 3,000 dollars per quarter, the MRR contribution is 1,000 dollars per month. MRR also equals ARR divided by 12.
What is the difference between MRR and ARR?
MRR measures recurring revenue on a monthly basis; ARR measures the same recurring revenue annualized. ARR equals MRR multiplied by 12. MRR is the operating metric for monthly-billed and early-stage SaaS, while ARR is the board and investor metric for annually-contracted SaaS.
Do setup fees count toward MRR?
No. Setup fees, implementation charges, professional services, training, and hardware sales are excluded from MRR. MRR captures only the recurring subscription revenue that renews on contract terms. Mixing one-time fees into MRR is the most common reporting error in early-stage SaaS.
What is Net New MRR?
Net New MRR is the change in MRR during a period. The formula is New MRR plus Expansion MRR minus Contraction MRR minus Churn MRR. A 40,000 dollar Net New MRR month means total MRR grew by 40,000 dollars after accounting for downgrades and cancellations.
How does usage-based pricing affect MRR?
For consumption-based pricing, only the committed minimum portion counts toward MRR. Variable overage above the commit is tracked as Consumption Revenue, not MRR. A customer with a 2,000 dollar monthly minimum and 4,500 dollars in usage contributes 2,000 dollars to MRR and 2,500 dollars to Consumption Revenue.
