Step-by-Step Worked Calculation
Scenario: Calculating MRR for a SaaS with multiple plans
A SaaS has 100 Basic plan customers at $29/mo, 50 Pro at $79/mo, and 10 Enterprise at $199/mo.
Step 1: Basic MRR = 100 × $29 = $2,900.
Step 2: Pro MRR = 50 × $79 = $3,950.
Step 3: Enterprise MRR = 10 × $199 = $1,990.
Step 4: Total MRR = $2,900 + $3,950 + $1,990 = $8,840.

- 1. Enter the number of customers for each subscription plan.
- 2. Input the monthly price for each plan.
- 3. The calculator computes your total MRR.
- 4. Track MRR growth over time.

What is MRR?
MRR (Monthly Recurring Revenue) is the predictable monthly revenue generated from active subscriptions. It is the fundamental metric for measuring the health and growth of subscription businesses.
How is MRR different from ARR?
MRR is monthly revenue while ARR (Annual Recurring Revenue) is annual. ARR = MRR × 12. MRR is more useful for short-term tracking, while ARR provides a bigger picture view.
What affects MRR growth?
New customer acquisitions, upgrades, downgrades, churn, and expansion revenue all impact MRR growth. Net MRR growth considers all these factors.
