MRR Calculator
Track your subscription revenue across multiple plans
How to Use This Tool
Add each subscription plan your business offers (e.g., Basic, Pro, Enterprise). For each plan, enter the number of paying subscribers and the monthly price they pay. Click Calculate MRR to see your total monthly recurring revenue, total customer count, average revenue per user (ARPU), and a breakdown of each plan's contribution. Use Add Another Plan if you have more than three pricing tiers, and Reset All to start over.
Formula and Logic
MRR (Monthly Recurring Revenue) = Sum of (Number of Subscribers × Monthly Price) across all plans.
Total Customers = Sum of subscribers across all plans.
ARPU (Average Revenue Per User) = Total MRR ÷ Total Customers.
Plan Contribution % = (Plan MRR ÷ Total MRR) × 100.
Practical Notes
Only include paying customers—exclude free trials or expired subscriptions. For annual plans, divide the annual price by 12 to get the monthly equivalent. If you offer discounts, enter the actual price paid by customers. MRR does not include one-time fees, setup charges, or non-recurring revenue. For usage-based pricing, calculate an average monthly revenue per customer based on historical data. In e-commerce, include only subscription products (like subscription boxes or memberships), not one-time purchases.
Why This Tool Is Useful
MRR is the lifeblood of subscription businesses—it predicts cash flow, measures growth, and informs hiring and marketing budgets. By breaking down MRR by plan, you can identify which tiers are most profitable and whether your pricing strategy aligns with customer value. Tracking ARPU helps you assess customer lifetime value and evaluate the impact of price changes. This tool is especially valuable for bootstrapped entrepreneurs who need to monitor revenue without expensive analytics software.
Frequently Asked Questions
What's the difference between MRR and ARR?
MRR (Monthly Recurring Revenue) is the predictable revenue earned each month. ARR (Annual Recurring Revenue) is MRR × 12, used for annual forecasting. Track MRR for short-term operational decisions and ARR for long-term strategic planning.
How do I handle churn or new subscriptions?
This calculator shows a snapshot of current MRR. To project future MRR, you'd need to factor in new subscriptions (expansion MRR) and cancellations (churn MRR). For churn analysis, track the number of subscribers lost each month and their associated revenue.
Should I include one-time fees or setup charges?
No. MRR only includes recurring revenue. One-time onboarding fees, installation charges, or non-recurring add-ons should be excluded. If you have recurring add-ons (e.g., extra storage), treat them as separate plans or add them to the relevant plan's monthly price.
Additional Guidance
For businesses with complex pricing (e.g., tiered usage, seat-based), calculate an effective monthly price per customer by dividing total subscription revenue by total subscribers. Regularly update this calculator (monthly or quarterly) to spot trends—declining MRR may signal rising churn or insufficient new business. Use the plan contribution breakdown to prioritize marketing: promote high-MRR plans or improve low-performing tiers. In B2B trade, negotiate annual contracts upfront but still convert to monthly equivalent for MRR calculations. Remember: MRR is a directional metric—accuracy depends on clean, up-to-date subscriber data from your billing system.
