📈 MRR Calculator
Calculate monthly recurring revenue and project growth
How to Use This Tool
Follow these steps to calculate your MRR accurately:
- Enter your total number of active subscribers in the first field. This includes all paying customers on recurring plans.
- Input your average monthly revenue per user (ARPU) — the average amount each subscriber pays per month.
- Select your primary currency from the dropdown to display results in your local format.
- Optionally add new subscribers, expansion revenue, and churned revenue to project next month’s MRR.
- Click Calculate MRR to see your full revenue breakdown.
- Use the Reset button to clear all fields and start over, or Copy Results to save your breakdown.
Formula and Logic
MRR is calculated using standard SaaS and subscription business metrics:
- Current MRR = Active Subscribers × Average Monthly Revenue Per User (ARPU)
- New MRR = New Subscribers Added × New Subscriber ARPU
- Net New MRR = New MRR + Expansion Revenue (Upgrades/Add-ons) − Churned Revenue (Cancellations/Downgrades)
- Projected Next Month MRR = Current MRR + Net New MRR
All optional fields default to 0 if left empty, so you can calculate basic MRR without adding growth metrics.
Practical Notes
These business-specific tips help you apply MRR calculations to real-world operations:
- Only include customers on recurring plans (monthly, quarterly, annual billed monthly) — exclude one-time purchases or consulting fees.
- ARPU should include all recurring add-ons, usage fees, and upgrades averaged across all subscribers.
- Churned revenue includes both customer churn (lost subscribers) and revenue churn (downgrades from existing subscribers).
- For annual plans billed upfront, divide the total annual payment by 12 to get the monthly recurring portion.
- Benchmark MRR growth rates for small SaaS businesses range from 5-15% monthly for early-stage companies, and 2-5% for mature businesses.
Why This Tool Is Useful
MRR is a core metric for any subscription-based business, including e-commerce sellers with recurring subscriptions, SaaS founders, and membership site owners.
- Track predictable revenue streams to forecast cash flow and plan budgets.
- Evaluate pricing strategy performance by comparing ARPU over time.
- Measure the impact of churn reduction and expansion revenue efforts on growth.
- Share standardized MRR reports with investors, stakeholders, or your internal team.
- Identify trends in new subscriber acquisition and revenue leakage from churn.
Frequently Asked Questions
What is the difference between MRR and ARR?
ARR (Annual Recurring Revenue) is MRR multiplied by 12. MRR tracks monthly performance, while ARR is used for annual forecasting and investor reporting.
Should I include annual subscribers in MRR?
Yes, but only the monthly portion. For an annual plan costing $1,200, count $100 per month toward your MRR, not the full $1,200 upfront.
How do I calculate ARPU for mixed pricing tiers?
Add up total monthly recurring revenue from all subscribers, then divide by the total number of active subscribers. This averages out different pricing tiers automatically.
Additional Guidance
Use this tool regularly to track MRR trends month over month. Compare your Net New MRR to your churn rate to determine if your business is growing or shrinking predictably.
For businesses with high expansion revenue, focus on upselling existing customers as this often has lower acquisition costs than attracting new subscribers.
If your churned revenue exceeds your new MRR, prioritize churn reduction strategies before investing in new customer acquisition to maximize growth efficiency.
