MRR vs ARR
MRR and ARR are the same revenue seen on two different time scales. People mix them up constantly, especially in investor conversations. Getting the terminology right matters because each number answers a different question about your subscription business.
MRR
MRR stands for monthly recurring revenue. It is the predictable subscription revenue your business brings in each month. It is the best number for tracking short-term growth, spotting churn, and making month-to-month operating decisions.
ARR
ARR stands for annual recurring revenue. It is simply MRR multiplied by 12. ARR gives you the yearly view of the same subscription base. Investors, boards, and valuation conversations almost always use ARR because it smooths out month-to-month noise.
MRR vs ARR: side by side
| Dimension | MRR | ARR |
|---|---|---|
| Time frame | Monthly view of subscription revenue. | Yearly view. MRR times 12. |
| Best use | Operating decisions, churn tracking, and short-term growth experiments. | Investor updates, valuation, and long-term planning. |
| What stage it suits | Early stage and day-to-day management when every month matters. | Scale stage and external reporting when you need a stable headline number. |
| What it excludes | One-time fees, setup fees, and professional services do not count. Only recurring subscription revenue counts. | Same as MRR. One-time fees and non-recurring revenue are excluded. |
Which one, when?
MRR: Track MRR for month-to-month decisions. Use it to measure trial-to-paid conversion, churn, expansion revenue, and the immediate impact of pricing changes. It is the operating metric for running the business.
ARR: Use ARR for investor and valuation conversations. It is the standard language for SaaS valuation multiples, board updates, and annual planning. When someone asks what your company is worth, they usually mean ARR.
Frequently asked questions
Is ARR just MRR times 12?
Yes, mostly. ARR is MRR multiplied by 12 for the annualized subscription run rate. The one caveat is contract length. If you sign annual contracts with upfront payments, ARR can also be calculated from committed annual contract value. But for standard month-to-month subscriptions, ARR equals MRR times 12.
When should I switch from MRR to ARR?
You do not have to choose one. Most SaaS businesses track both. Start with MRR when you are small and iterating fast. Add ARR as your default external metric once you cross roughly one million dollars in ARR or start talking to investors regularly.
Do one-time fees count toward MRR?
No. One-time fees, setup fees, professional services, and consulting revenue do not count toward MRR because they are not recurring. MRR and ARR only include revenue that repeats on a subscription basis. Counting one-time fees inflates your recurring number and misleads investors.
