What Are SaaS Metrics?
SaaS (Software as a Service) metrics are key performance indicators specifically designed to measure the health and growth of subscription-based businesses. Unlike traditional businesses that focus on one-time sales, SaaS companies generate recurring revenue, making metrics around retention, growth, and customer lifetime value critically important.
These metrics help founders, executives, and investors understand whether a SaaS business is sustainable, growing efficiently, and creating long-term value. The interconnected nature of SaaS metrics means that improving one area often positively impacts others.
Monthly Recurring Revenue (MRR)
MRR is the foundation of SaaS financial metrics. It represents the predictable, recurring revenue your business generates each month from subscriptions.
MRR Components
- New MRR: Revenue from newly acquired customers
- Expansion MRR: Additional revenue from existing customers (upgrades, add-ons)
- Reactivation MRR: Revenue from previously churned customers who return
- Contraction MRR: Revenue lost from downgrades
- Churned MRR: Revenue lost from cancellations
Starting MRR: $100,000
+ New MRR: $15,000
+ Expansion MRR: $5,000
+ Reactivation MRR: $1,000
- Contraction MRR: $2,000
- Churned MRR: $4,000
= Ending MRR: $115,000
Net New MRR: $15,000 (15% growth)
Annual Recurring Revenue (ARR)
ARR normalizes your recurring revenue to an annual view. For most companies:
ARR is typically used for businesses with primarily annual contracts or when communicating to investors. It's easier to compare against annual expenses and industry benchmarks.
Customer & Revenue Churn Rate

Net Revenue Retention (NRR)
NRR (also called Net Dollar Retention or NDR) measures how much revenue you retain and grow from your existing customer base over time. It's one of the most important SaaS metrics.
- NRR > 100%: Excellent! Your existing customers are worth more over time (expansion exceeds churn)
- NRR = 100%: Neutral - expansion equals churn
- NRR < 100%: You're losing revenue from existing customers
- Elite SaaS: 120%+ NRR (common in enterprise software)
ARPA - Average Revenue Per Account
ARPA helps you understand the average value of each customer relationship:
Tracking ARPA over time shows whether you're moving upmarket (increasing ARPA) or down (decreasing ARPA). Growing ARPA typically indicates successful upselling and attracting larger customers.

Frequently Asked Questions
What's the difference between customer churn and revenue churn?
Customer churn counts the number of customers lost, while revenue churn measures the dollar value lost. A company might have 5% customer churn but only 2% revenue churn if smaller customers tend to leave. Conversely, losing a few large customers could mean low customer churn but high revenue churn.
How often should I calculate these metrics?
Most SaaS companies track these metrics monthly, with weekly monitoring of leading indicators like trial conversions and engagement. Quarterly and annual views help identify trends and inform strategic planning.
What if my NRR is below 100%?
NRR below 100% means you're losing revenue from existing customers faster than you're expanding it. Focus on reducing churn through better onboarding, customer success, and identifying at-risk customers early. Also look for expansion opportunities through upselling and cross-selling.
Should I include free trial users in customer counts?
Generally, no. Only count paying customers in your metrics. Free trials can be tracked separately as a leading indicator of future growth. Converting free trials to paid is part of your customer acquisition funnel, not your customer base.
How do I calculate churn for annual contracts?
For annual contracts, you can either calculate annual churn at renewal time or normalize to monthly by dividing annual churn by 12. Be consistent in how you report it. Some companies track "logo retention rate at renewal" separately from monthly churn.
