MRR and ARR calculator
Enter your customer count and average monthly revenue to see your MRR and ARR. The numbers stay in your browser. Nothing is sent anywhere.
120 customers at $500 a month is $720,000 in ARR.
What are MRR and ARR
MRR is monthly recurring revenue. It is the total revenue you can count on each month from your paying customers, before one time fees or discounts skew the picture. ARR is annual recurring revenue, the same idea stretched across a year.
Both numbers strip out the noise of one off invoices and let you see the steady, repeating base of your business. Investors, boards, and your own team use them as the main pulse check on a subscription business.
How to calculate MRR and ARR
MRR equals your number of customers multiplied by the average monthly revenue per customer. If you have 120 customers paying 500 dollars a month on average, your MRR is 60,000 dollars. ARR is simply MRR multiplied by 12, so that same business runs at 720,000 dollars a year.
Most teams track MRR month over month to catch changes early, then report ARR to investors and in board decks since it reads as a cleaner, bigger number. Keep the customer count and average revenue clean and the two figures stay easy to trust.
How to grow MRR and ARR
There are only two levers. Add more paying customers, or raise the average revenue each one pays through upgrades, upsells, or better pricing tiers. Watching both levers separately tells you whether growth is coming from new logos or from expansion in existing accounts.
The hard part is trusting the inputs. If customer counts or billing data live in a CRM that does not match how your team actually manages accounts, MRR drifts from reality. A CRM built around your real workflow keeps the customer and revenue data clean enough to report on with confidence.
What is a good MRR growth rate
Healthy growth and retention targets shift a lot by company stage. Use these as rough orientation, not a scorecard.
| Stage | Healthy annual growth | Net revenue retention |
|---|---|---|
| Early startup (pre seed to Series A) | 100 percent or more, roughly doubling | 90 to 100 percent |
| Growth stage (Series B to C) | 40 to 100 percent | 100 to 110 percent |
| Scale (later stage, larger ARR base) | 20 to 40 percent | 110 to 120 percent or higher |
These are general ranges to orient you, not a guarantee. Your numbers depend on your market, pricing, and how you sell. Larger ARR bases naturally grow slower in percentage terms even as dollar growth stays strong.
How to grow MRR and ARR
Add new paying customers
Bring in more logos at your current price point. This is the most direct lever, but it is also the most expensive if your sales and marketing costs are high.
Raise average revenue per customer
Adjust pricing tiers, add paid features, or move new customers to a higher plan. Small increases in average revenue per customer compound across your whole base.
Cut churn
Every customer who cancels drags down MRR the next month. Fixing onboarding gaps and catching unhappy accounts early protects the revenue you already have.
Expand existing accounts
Upsell add ons, seats, or higher tiers to customers already paying you. Expansion revenue is usually cheaper to win than a brand new customer.
Keep customer and billing data clean
MRR and ARR are only as trustworthy as the records behind them. A CRM that matches how your team actually manages accounts and billing keeps the inputs accurate.
