Fill in your customer count and ARPU (or switch to Component or Multi-Tier mode) to see your MRR, ARR, growth projections, CLV, and SaaS health benchmarks.
How to Use the MRR Calculator
اختر وضع حسابك
Select Simple mode if you know your customer count and ARPU. Switch to Component mode if you track MRR movement by type (New, Expansion, Contraction, Churned, Reactivation). Use Multi-Tier mode if you have multiple pricing plans with different prices and customer counts.
Enter Your Subscription Data
In Simple mode, enter your total active paying customers and your monthly ARPU. Remember: normalize non-monthly billing cycles — annual plans divide by 12, quarterly by 3. Enter growth rate and churn rate to unlock 12-month projections and CLV calculations.
Review Your MRR, ARR, and Health Metrics
Results update instantly as you type. Review MRR, ARR, ARPU, and CLV in the top section. In Simple mode, view your 12-month projection chart. In Component mode, analyze the MRR movement waterfall to see which components are growing or shrinking your revenue. In Multi-Tier mode, see how each pricing plan contributes to total MRR.
Compare Against Benchmarks and Export
Scroll down to the SaaS Industry Benchmarks panel to compare your churn rate, NRR, and growth rate against early-stage, healthy, and world-class targets. Use the Export CSV button to download your full MRR summary for reports or spreadsheets. Use the Print button for investor-ready printed output.
الأسئلة الشائعة
What is MRR and how is it different from revenue?
MRR (Monthly Recurring Revenue) measures only the predictable, subscription-based revenue your business generates each month from active paying customers. It excludes one-time payments, setup fees, consulting, hardware, and trial users who have not converted. Regular revenue in accounting may include all of these. MRR is strictly recurring. A company might report $200K in monthly revenue but only $150K in MRR if $50K came from one-time professional services engagements. Investors and SaaS benchmarks exclusively use MRR because it represents the durable, growing engine of the business — the part that compounds over time with strong retention.
How do I calculate MRR from annual subscriptions?
To normalize annual subscriptions into MRR, divide the annual contract value by 12. A customer paying $1,200/year contributes $100/month to MRR, not $1,200 in the month they paid. Similarly, quarterly subscriptions divide by 3, and semi-annual subscriptions divide by 6. Weekly subscriptions multiply by 4.33 (52 weeks ÷ 12 months). This normalization is critical for accurate MRR because it prevents spikes and valleys in your MRR chart based purely on billing timing rather than actual subscription growth. Most SaaS finance tools, including Stripe Billing and Chargebee, apply this normalization automatically.
What is Net Revenue Retention (NRR) and why does it matter?
Net Revenue Retention (NRR) measures what percentage of your beginning-of-month MRR you retain from existing customers after accounting for expansions, contractions, and churn — but before counting new customers. The formula is: NRR = (Beginning MRR + Expansion MRR − Contraction MRR − Churned MRR) ÷ Beginning MRR × 100. NRR above 100% means your existing customer base alone grows your revenue month over month, even if you acquire zero new customers. This is the holy grail of SaaS metrics and indicates strong product-market fit with upsell potential. Top SaaS companies like Snowflake (158% NRR), Datadog (130%+), and CrowdStrike have achieved sustained NRR well above 120%.
What is a healthy monthly churn rate for SaaS?
Monthly churn rates vary significantly by market segment. Consumer SaaS generally accepts higher churn (5–10%/month) because of lower switching costs. B2B SMB SaaS should target under 5% monthly churn. Mid-market SaaS should aim for under 3%, and enterprise SaaS should target under 1–2%. As a general rule: under 2% monthly churn is healthy and sustainable; under 1% is excellent; under 0.5% is world-class and typically only seen in enterprise products with high switching costs and deeply embedded workflows. Note that monthly churn of 2% compounds to roughly 22% annual churn, which is already a significant headwind to growth. Prioritizing churn reduction typically yields a higher return on investment than equivalent spend on customer acquisition.
How is Customer Lifetime Value (CLV) calculated for subscription businesses?
For subscription businesses with a known monthly churn rate, CLV is calculated as: CLV = ARPU ÷ Monthly Churn Rate. For example, if ARPU is $100/month and monthly churn is 2%, CLV = $100 ÷ 0.02 = $5,000. The customer lifetime in months is 1 ÷ Monthly Churn Rate = 50 months in this example. CLV is critical for determining how much you can afford to spend acquiring a new customer (Customer Acquisition Cost, or CAC). A healthy SaaS business typically targets a CLV:CAC ratio of at least 3:1 — meaning the lifetime value of each customer is at least three times what you spent to acquire them. A ratio below 1:1 means you are destroying value with each new customer acquired.
What should not be included in MRR?
Several revenue types are commonly and incorrectly included in MRR calculations. One-time setup fees or onboarding fees should never be included, even if they recur across customers, because they are not recurring from the same customer. Professional services, consulting, or implementation fees are excluded. Hardware purchases are excluded. Trial period revenue (free trials, discounted first months before a real subscription begins) is excluded. Revenue from customers who have cancelled or are past-due should be removed from MRR even if the cash has already been collected. Annual or multi-year contracts must be normalized to monthly, not recorded as a lump sum. Including any of these inflates MRR and produces misleading growth signals and incorrect CLV calculations.
