"What gets measured gets managed. If you're not tracking the right metrics, you're flying blind in your SaaS business." - Peter Drucker
As an indie hacker or solo founder, you're wearing multiple hats. You can't afford to track everything, but you also can't afford to ignore the metrics that actually matter for your SaaS growth.
Here are the 15 essential SaaS metrics you should be tracking, organized by what stage you're at and what they tell you about your business.
📈 Revenue Metrics
1. Monthly Recurring Revenue (MRR)
The total predictable revenue your customers generate each month. This is your north star metric.
Formula: Sum of all monthly subscription revenue
Why it matters: Shows your business health and growth trajectory
2. Annual Recurring Revenue (ARR)
MRR multiplied by 12. Useful for annual planning and investor conversations.
3. Average Revenue Per User (ARPU)
How much revenue you generate per customer on average.
Formula: Total MRR ÷ Number of customers
Why it matters: Helps you understand customer value and pricing effectiveness
💰 Customer Acquisition Metrics
4. Customer Acquisition Cost (CAC)
How much it costs to acquire a new customer.
Formula: Total sales & marketing costs ÷ Number of new customers
Why it matters: Determines if your acquisition strategy is sustainable
5. CAC Payback Period
How long it takes to recover the cost of acquiring a customer.
Good benchmark: Under 12 months for most SaaS businesses
Why it matters: Affects your cash flow and growth capacity
6. Lead Conversion Rate
Percentage of leads that become paying customers.
👥 Customer Retention Metrics
7. Customer Churn Rate
Percentage of customers who cancel their subscriptions each month.
Formula: (Customers lost ÷ Total customers) × 100
Good benchmark: Under 5% monthly for B2B, under 10% for B2C
8. Revenue Churn Rate
Percentage of revenue lost from churned customers.
9. Customer Lifetime Value (LTV)
Total revenue you can expect from a single customer account.
Formula: ARPU × Customer lifetime
Rule of thumb: LTV should be at least 3x CAC
10. Net Revenue Retention (NRR)
Revenue from existing customers including upgrades, downgrades, and churn.
Good benchmark: Over 100% (means you're growing from existing customers)
🎯 Product & Engagement Metrics
11. Daily Active Users (DAU) / Monthly Active Users (MAU)
How many people use your product daily vs monthly.
DAU/MAU ratio: Shows product stickiness
Good benchmark: 20%+ for most SaaS products
12. Feature Adoption Rate
Percentage of users who use specific features.
13. Time to Value (TTV)
How long it takes for new users to experience your product's core value.
📊 Financial Health Metrics
14. Gross Margin
Revenue after accounting for the cost of goods sold.
Good benchmark: 80%+ for most SaaS businesses
15. Burn Rate & Runway
How much cash you're burning monthly and how long you can operate.
🚀 How to Actually Track These Metrics
Don't try to track everything at once. Here's a phased approach:
Pre-Launch (0-10 customers)
Track: MRR, CAC, basic engagement
Early Stage (10-100 customers)
Add: Churn rate, LTV, feature adoption
Growth Stage (100+ customers)
Add: NRR, DAU/MAU, financial metrics

⚠️ Common Mistakes to Avoid
Vanity Metrics
Don't focus on metrics that look good but don't drive decisions (like total signups without activation).
Analysis Paralysis
Don't track so many metrics that you can't make decisions. Focus on 3-5 key metrics at each stage.
Ignoring Context
Metrics mean nothing without context. Always compare against your baseline and industry benchmarks.
Remember: The goal isn't to track metrics for tracking's sake. The goal is to use data to make better decisions for your SaaS business.
