1. Introduction
Running a successful SaaS business isn’t just about building a great product—it’s about understanding and optimizing your key performance metrics. These metrics provide valuable insights into your growth, customer behavior, and overall business health.
In this post, I’ll walk you through 8 essential SaaS metrics that every founder should track to make informed decisions, reduce churn, and increase monthly recurring revenue (MRR).
2. Why SaaS Metrics Matter
Data-Driven Decisions: Metrics give you a clear picture of what’s working and what isn’t.
Predictable Growth: Tracking key metrics like churn and LTV helps you forecast revenue more accurately.
Improved Customer Retention: By analyzing churn rates and activation metrics, you can identify issues before they become major problems.
3. 8 Essential SaaS Metrics to Track
1. Monthly Recurring Revenue (MRR)
Definition: The total predictable revenue your SaaS business generates each month from subscriptions.
Why It Matters:
MRR helps you understand how much revenue you can rely on month after month.
How to Calculate MRR:
[ MRR = Total Active Subscribers × Average Monthly Subscription Price ]
Pro Tip: Break MRR into categories:
New MRR: Revenue from new customers.
Expansion MRR: Revenue from upsells and cross-sells.
Churned MRR: Revenue lost due to cancellations.
2. Customer Acquisition Cost (CAC)
Definition: The cost of acquiring a new customer, including marketing and sales expenses.
Why It Matters:
Tracking CAC helps you ensure that you’re spending efficiently and not overspending to acquire users.
How to Calculate CAC:
[ CAC = Total Sales and Marketing Costs ÷ Number of New Customers Acquired ]
Pro Tip: Compare your CAC to your Customer Lifetime Value (CLV)—you want CLV to be significantly higher than CAC.
3. Customer Lifetime Value (CLV)
Definition: The total revenue you can expect from a customer over the entire duration of their subscription.
Why It Matters:
CLV helps you understand how valuable your customers are and how much you can afford to spend on acquiring them.
How to Calculate CLV:
[ CLV = (Average Monthly Revenue Per Customer) × (Average Customer Lifespan in Months) ]
4. Churn Rate
Definition: The percentage of customers who cancel their subscriptions over a specific period.
Why It Matters:
Churn directly impacts your MRR—too much churn can prevent your SaaS from growing sustainably.
How to Calculate Churn Rate:
[ Churn Rate = (Number of Customers Churned ÷ Total Customers) × 100 ]
Pro Tip: Track both customer churn (number of users lost) and revenue churn (MRR lost due to cancellations).
5. Net Revenue Retention (NRR)
Definition: The percentage of recurring revenue retained from existing customers after accounting for upgrades, downgrades, and churn.
Why It Matters:
A high NRR shows that your product provides enough value to retain and grow revenue from existing customers.
How to Calculate NRR:
[ NRR = ((MRR at Start + Expansion MRR – Churned MRR) ÷ MRR at Start) × 100 ]
Pro Tip: An NRR above 100% means your expansion revenue is outpacing churn, leading to "net negative churn"—a SaaS growth goldmine.
6. Activation Rate
Definition: The percentage of new users who reach a key milestone or "aha moment" during onboarding.
Why It Matters:
Activation rate measures how effective your onboarding process is at getting users to experience value quickly.
How to Calculate Activation Rate:
[ Activation Rate = (Activated Users ÷ Total New Signups) × 100 ]
Pro Tip: Identify the actions that correlate most with long-term usage (e.g., completing a setup step or sending a first email campaign).
7. Average Revenue Per User (ARPU)
Definition: The average monthly revenue you earn per customer.
Why It Matters:
ARPU helps you measure the overall value of your customer base and track revenue changes over time.
How to Calculate ARPU:
[ ARPU = Total MRR ÷ Number of Active Customers ]
Pro Tip: Increasing ARPU through upsells and cross-sells can have a significant impact on your bottom line without increasing customer acquisition costs.
8. Time to Value (TTV)
Definition: The time it takes for a customer to experience the value of your SaaS product after signing up.
Why It Matters:
A shorter TTV increases customer satisfaction and reduces the likelihood of churn during the onboarding phase.
How to Measure TTV:
Track the average number of days or steps it takes for users to complete an action that correlates with success (e.g., publishing their first blog post or completing their first project).
4. Bonus Metric: Expansion MRR
Definition: The additional monthly revenue generated from upsells, cross-sells, or upgrades.
Why It Matters:
Expansion MRR helps you measure how effectively you’re growing your revenue from existing customers.
5. How to Track Your SaaS Metrics
1. Analytics Tools
Baremetrics: A SaaS analytics platform for tracking MRR, churn, and more.
Stripe Analytics: Great for tracking payments and subscription data.
Google Analytics: Use it to track user behavior on your website and app.
2. Internal Dashboards
Create custom dashboards using tools like Looker, Notion, or Tableau to visualize your key metrics in real time.
6. Common Mistakes to Avoid
Ignoring Churn Metrics: Churn should be one of your most closely monitored KPIs—ignoring it can lead to misleading growth metrics.
Focusing Only on Acquisition: Don’t just track new signups—focus equally on retention and expansion MRR.
Not Segmenting Metrics: Break down metrics by customer segment (e.g., SMBs vs. enterprise) to get a clearer view of performance.
7. Conclusion
Tracking the right SaaS metrics can help you grow faster, improve customer satisfaction, and make data-driven decisions. By monitoring MRR, churn, CAC, and NRR, you’ll gain a deeper understanding of your business performance and build a SaaS company that scales sustainably.
