SaaS Metrics Calculator: Essential KPIs for Your Business
Understanding and tracking SaaS metrics is crucial for building a sustainable subscription business. This calculator helps you compute the most important key performance indicators (KPIs) that investors, board members, and management teams use to evaluate SaaS company health.
Key SaaS Metrics Explained
Monthly Recurring Revenue (MRR)
MRR is the predictable total revenue your business generates each month from all active subscriptions. It's the foundational metric for any SaaS business because it represents the core value of your recurring business model.
Types of MRR:
- New MRR: Revenue from new customers
- Expansion MRR: Additional revenue from existing customers (upgrades)
- Churned MRR: Lost revenue from cancelled subscriptions
- Net New MRR: New MRR + Expansion MRR - Churned MRR
Annual Recurring Revenue (ARR)
ARR is simply MRR multiplied by 12, representing the yearly value of your recurring revenue. This metric is especially important for enterprise SaaS companies and is often used in company valuations.
Churn Rate
Churn rate measures the percentage of customers who cancel their subscription within a given period. There are two types:
- Customer Churn: Percentage of customers lost
- Revenue Churn: Percentage of MRR lost (accounts for different pricing tiers)
Low churn is critical for SaaS success. Even small improvements in churn can dramatically impact long-term revenue.
Customer Lifetime Value (LTV)
LTV represents the total revenue you can expect from a customer over their entire relationship with your company. It's calculated by dividing the average revenue per user by the churn rate.
A high LTV indicates strong customer retention and monetization.
Customer Acquisition Cost (CAC)
CAC is the total cost of acquiring a new customer, including marketing, sales, and related expenses. Understanding CAC helps you determine sustainable growth strategies.
LTV:CAC Ratio
This ratio compares customer lifetime value to acquisition cost. It tells you whether your customer acquisition is profitable and sustainable.
ARR = MRR x 12
Churn Rate = Churned Customers / Total Customers
LTV = ARPU / Monthly Churn Rate
LTV:CAC Ratio = LTV / CAC
Growth Rate = (New - Churned) / Total
Industry Benchmarks
| Metric | Poor | Average | Good | Excellent |
|---|---|---|---|---|
| Monthly Churn Rate | >5% | 3-5% | 1-3% | <1% |
| LTV:CAC Ratio | <1:1 | 1:1 - 2:1 | 3:1 - 5:1 | >5:1 |
| Net Revenue Retention | <90% | 90-100% | 100-120% | >120% |
| Monthly Growth Rate | <2% | 2-5% | 5-10% | >10% |
Understanding the Health Score
The calculator provides a health score based on your metrics compared to industry benchmarks:
- Excellent (80-100): Your SaaS metrics indicate a highly healthy business with strong unit economics
- Good (60-79): Solid fundamentals with room for optimization
- Fair (40-59): Some metrics need attention; focus on improving weak areas
- Needs Improvement (0-39): Critical areas require immediate attention

The Rule of 40
A popular benchmark for SaaS companies is the "Rule of 40," which states that a healthy SaaS company's growth rate plus profit margin should equal or exceed 40%. For example:
- 50% growth + -10% margin = 40% (Healthy)
- 20% growth + 25% margin = 45% (Healthy)
- 10% growth + 10% margin = 20% (Needs improvement)
Conclusion

Use this calculator regularly to monitor your key metrics, identify trends, and make informed decisions about product, pricing, and growth strategies. Remember that context matters - early-stage companies will have different benchmark expectations than mature enterprises.
