What This Calculator Tells You

Monthly recurring revenue (MRR) is the predictable subscription revenue you earn each month. It is the base number behind ARR, churn, LTV and almost every SaaS dashboard.

Enter your number of active paying customers and their average revenue per user (ARPU). The calculator returns MRR and the matching ARR.

What to Enter

Active paying customers — accounts on a paid plan today. Exclude free trials and free plans.
ARPU per month ($) — average monthly subscription revenue per paying customer, after recurring discounts. For annual plans divide the yearly price by 12.

Worked Examples

1. A single-plan product

320 customers each paying $79 a month.

Enter 320 and 79 → MRR $25,280, ARR $303,360.

2. Three pricing tiers

200 customers on $29, 80 on $99 and 12 on $299.

Total MRR = $5,800 + $7,920 + $3,588 = $17,308 across 292 customers, so ARPU is about $59.27.
Enter 292 and 59.27 to confirm, then watch how ARPU moves as you change plan mix.

3. Annual plans

A plan sold at $588 a year counts as $49 of MRR per customer.

150 annual customers at $49 plus 90 monthly customers at $59 → $7,350 + $5,310 = $12,660 MRR.

How It’s Calculated

MRR = Σ (Customers × Monthly Plan Price). Annual plans: divide annual price by 12.

How to Read Your Result

Track MRR movements, not just the total: new MRR, expansion, contraction and churned MRR explain why the number changed.
Month-over-month growth of 10–15% is strong for early SaaS; it naturally slows as the base grows.
Rising ARPU with flat customer count usually means upsells or price increases are working.
Next step: check how much of that MRR you keep with the churn rate calculator.

Common Mistakes to Avoid

Including trials or free users in the customer count, which drags ARPU down.
Booking annual payments in one month. Always normalize to a monthly amount.
Adding one-time fees such as onboarding or hardware.
Ignoring discounts. A $99 plan sold at 30% off is $69.30 of MRR.

Frequently Asked Questions

How is MRR calculated?

MRR = number of paying customers × average monthly revenue per customer. Equivalently, add up every active subscription's monthly value.

What is a good MRR growth rate?

Early-stage SaaS companies often target 10–20% month-over-month; at $1M+ ARR, 5–10% monthly is strong. Compare against your own trend.

Do annual plans count toward MRR?

Yes, divided by 12. A $1,200-a-year plan adds $100 of MRR each month of the contract.

What is the difference between MRR and cash collected?

Cash collected depends on billing timing. An annual customer pays all at once, but MRR spreads that value evenly across the year.
