What is MRR (Monthly Recurring Revenue)?
Definition
MRR (Monthly Recurring Revenue) is the normalized monthly value of all active subscriptions, retainers, and recurring billing relationships. For a SaaS with $99/mo and $990/yr plans, the $990/yr customer contributes $82.50 to MRR ($990 ÷ 12).
MRR is the foundation metric for any business with predictable revenue: SaaS, newsletter subscriptions, coaching retainers, hosting subscriptions. It's not the same as cash — it's a forward-looking view of contracted revenue per month.
Why it matters
- MRR × 12 gives you ARR (Annual Recurring Revenue), the benchmark investors and operators use to size a subscription business. A freelancer with $8k/mo in retainers has $96k ARR — the same language enterprise SaaS uses.
- Changes in MRR (expansions, contractions, churn, new) reveal business health far faster than revenue totals. A flat MRR total hiding 20% churn replaced by 20% new is a very different business from a stable one.
- For indie SaaS founders and creators with paid subscriptions, MRR is the primary KPI. Every product and pricing decision should have a theory about how it moves MRR.
Best practices for MRR
Track MRR components separately
Break MRR into: new MRR (new customers), expansion MRR (existing customers upgrading), contraction MRR (downgrades), and churn MRR (cancellations). Net MRR change = new + expansion − contraction − churn.
Normalize annual plans to monthly
A $1,200/yr plan contributes $100 to MRR, not $1,200. Always divide annual pricing by 12. This makes month-over-month comparisons sane and prevents apparent MRR spikes when an annual plan renews.
Watch churn more than any other component
10% monthly churn caps your business at 10× current MRR even with zero growth. 5% monthly churn caps it at 20×. 2% monthly caps it at 50×. Churn compounds more than acquisition does.
Separate MRR from non-recurring revenue
One-time fees, setup charges, and consulting add-ons aren't MRR. Tracking them together inflates the predictability of your revenue. Keep them in a separate category and report both numbers.
FAQ
How is MRR different from revenue?
MRR is the monthly rate of contracted recurring revenue. Revenue is what you actually collected in a given period, including one-time fees, setup charges, and consulting. MRR is forward-looking; revenue is backward-looking.
Does a paused subscription count in MRR?
No. Active subscriptions only. Paused users are typically tracked as a leading indicator of churn — they often come back, but when they don't, they become churned MRR.
How do I calculate MRR for variable-price subscriptions?
Use the most recent billed amount. For a customer with usage-based pricing, MRR is their most recent month's charge. Volatile customers should be flagged and tracked separately.
