Monthly Recurring Revenue and Annual Recurring Revenue compared side by side. Know when to use each and how they drive different business decisions.
MRR is the predictable, recurring revenue your business earns in a single month from active subscriptions. It is the pulse of a SaaS business and the primary day-to-day operating metric.
Granular, sensitive to change, and ideal for tracking growth momentum week-over-week and month-over-month.
ARR is MRR multiplied by 12 and represents the annualized run rate of your recurring revenue. It is the standard metric for investor reporting, valuation, and annual planning.
Smoother, less volatile, and ideal for year-over-year comparisons and enterprise deal sizing.
MRR = Sum of all recurring monthly subscription revenueExample: 100 customers at $50/month + 20 customers at $200/month = $5,000 + $4,000 = $9,000 MRR
ARR = MRR x 12Example: $9,000 MRR x 12 = $108,000 ARR. For annual contracts, ARR = Total contract value / Contract length in years.
Net New MRR = New MRR + Expansion MRR - Churned MRR - Contraction MRRBreaking MRR into components reveals growth quality: healthy companies grow through expansion, not just new customer acquisition.
| Criteria | MRR | ARR |
|---|---|---|
| Time Horizon | Monthly | Annual (run rate) |
| Relationship | MRR = ARR / 12 | ARR = MRR x 12 |
| Primary Use | Operations, sales tracking, growth monitoring | Investor reporting, valuation, annual planning |
| Volatility | High (reflects monthly changes immediately) | Smooth (small monthly changes have less impact) |
| Best Stage | Early-stage and growth companies | Series A+ and growth-to-mature companies |
| Valuation Multiple | Not standard (convert to ARR first) | Standard: 5x-15x ARR for private SaaS |
| Churn Sensitivity | Very high - shows impact in same month | Lower - impact spread over 12-month view |
| Reporting Cadence | Weekly or monthly dashboards | Quarterly board reports, investor updates |
| Common Mistake | Including one-time fees or services revenue | Treating ARR as actual cash received (it is a run rate) |
Tracking MRR in aggregate is good. Tracking its components is great. The four MRR movement types reveal the quality and sustainability of your growth.
New MRR
Revenue from brand new customers acquired this month. The purest signal of new customer acquisition effectiveness.
Expansion MRR
Revenue from existing customers upgrading their plan or purchasing add-ons. The healthiest growth signal for product-led companies.
Contraction MRR
Revenue lost from existing customers downgrading. A warning signal that customers are not getting enough value to justify their current plan.
Churned MRR
Revenue lost from customers who canceled their subscriptions entirely. High churned MRR signals product-market fit or retention issues.
Including non-recurring revenue in MRR
Setup fees, professional services, and one-time charges are not recurring. Including them inflates MRR and creates misleading month-to-month comparisons.
Confusing ARR with actual cash collected
ARR is a run-rate metric, not a cash flow statement. A company with $1M ARR has not necessarily collected $1M in cash. Annual contracts paid upfront affect cash flow separately from ARR.
Counting trials or freemium users in MRR
Free trials and freemium accounts generate no revenue. Only include customers who are actively paying for a subscription.
Using TCV instead of ACV for ARR
Total Contract Value (TCV) for a 3-year deal is not the same as ARR. ARR should reflect the annual recurring value, not the full contract sum.

MRR (Monthly Recurring Revenue) is the predictable recurring revenue your business earns in a single month. ARR (Annual Recurring Revenue) is simply MRR multiplied by 12, representing the annualized run rate of that recurring revenue. They measure the same underlying business health at different time scales. MRR is more granular and useful for spotting trends month-over-month, while ARR provides a smoother, higher-level view that is easier to benchmark against annual targets.
Use MRR for day-to-day and month-to-month operational decisions: tracking churn impact, measuring the effect of new feature launches, or monitoring sales team performance. Use ARR for strategic conversations, investor reporting, and annual planning. Early-stage companies often focus on MRR because it reflects weekly and monthly momentum more clearly. Growth-stage and later-stage companies shift toward ARR as the primary headline metric because it aligns with annual budgeting and enterprise deal sizes.
Investors typically want to see ARR as the headline metric for Series A and beyond because it is comparable across companies and aligns with standard valuation multiples (e.g., 10x ARR). However, sophisticated investors will always dig into MRR trends to understand growth velocity, churn patterns, and new bookings composition. For seed-stage companies and early-stage startups, MRR is often more appropriate because ARR can make small businesses appear larger than they are, and monthly granularity is more meaningful at that stage.
ARR = MRR x 12. This is a straightforward multiplication. Important: ARR is a run-rate metric, not an actual annual total. It represents what your revenue would be over 12 months if your current MRR stayed constant. It does not account for future growth or churn. If your company earns $83,333 in MRR, your ARR is $1,000,000. One common mistake is including one-time fees or non-recurring revenue in MRR/ARR calculations. Both metrics should only include truly recurring, contractually committed revenue.
