Understanding SaaS Metrics
SaaS metrics are the vital signs of your subscription business. Unlike traditional businesses, SaaS companies need to track recurring revenue, customer retention, and unit economics to understand business health and forecast growth.
The SaaS Metrics That Matter
- MRR/ARR: Monthly and Annual Recurring Revenue - your predictable revenue base
- LTV:CAC: Lifetime Value to Customer Acquisition Cost ratio - unit economics
- NRR: Net Revenue Retention - revenue growth from existing customers
- Quick Ratio: Growth efficiency - how much growth vs. churn
Frequently Asked Questions
What are the most important SaaS metrics?
The key SaaS metrics are MRR/ARR (revenue), LTV:CAC ratio (unit economics), Net Revenue Retention (growth quality), Gross Churn Rate (customer loss), and Quick Ratio (growth efficiency). Together, these tell you if your business is healthy and growing sustainably.
What is a good LTV:CAC ratio?
A healthy LTV:CAC ratio is 3:1 or higher, meaning customer lifetime value is 3x the cost to acquire them. Below 1:1 means you lose money on each customer. 5:1+ suggests you may be underinvesting in growth and could acquire customers more aggressively.
What is Net Revenue Retention (NRR)?
NRR measures revenue from existing customers after accounting for upgrades, downgrades, and churn. 100%+ means expansion exceeds churn (negative net churn). Top SaaS companies achieve 120-150% NRR, meaning they grow revenue without acquiring new customers.
What is the SaaS Quick Ratio?
Quick Ratio = (New MRR + Expansion MRR) / (Churned MRR + Contraction MRR). It measures growth efficiency. A ratio of 4+ is excellent, 2-4 is good, below 2 means churn is eating into growth. Its a key indicator of sustainable growth.
How do I calculate CAC payback period?
CAC Payback = CAC / (ARPU × Gross Margin). It measures months to recover customer acquisition cost. Under 12 months is excellent, 12-18 is acceptable, over 18 months signals inefficient acquisition. Shorter payback means faster reinvestment in growth.
