B2B SaaS Metrics
Essential B2B SaaS metrics fall into four main categories: Growth metrics (MRR/ARR, Growth Rate), Retention metrics (NRR, GRR, Churn Rate), Acquisition metrics (CAC, CAC Payback, Conversion Rate), and Profitability metrics (LTV, Gross Margin, Rule of 40, Magic Number). Master these numbers and you'll know exactly where your business stands and where it's headed.
Understanding B2B SaaS Metrics
Tracking the right metrics is crucial for understanding business health and guiding strategic decisions. Unlike traditional businesses, SaaS companies operate on subscription models, creating unique dynamics around customer acquisition, retention, and monetization that require specialized measurement approaches.
SaaS metrics can generally be grouped into several key categories:
1: Growth Metrics
Monthly Recurring Revenue (MRR) – The predictable revenue your business generates each month from subscriptions.
Annual Recurring Revenue (ARR) – Similar to MRR but annualized, providing a yearly view of recurring revenue.
Growth Rate – The percentage increase in MRR or ARR over a specific period, typically measured monthly, quarterly, or annually.
2: Retention Metrics
Net Revenue Retention (NRR) – Measures the percentage of revenue retained from existing customers over a period, including expansions, contractions, and churn. An NRR over 100% indicates that growth from existing customers exceeds losses.
Gross Revenue Retention (GRR) – Similar to NRR but excludes expansion revenue, focusing only on how much initial revenue is retained. Always below or equal to 100%.
Logo Retention – The percentage of customers (not revenue) retained over a given period.
Churn Rate – The percentage of customers or revenue lost during a period. Can be measured as:
- Customer Churn Rate – Percentage of customers lost
- Revenue Churn Rate – Percentage of revenue lost
3: Customer Acquisition Metrics
Customer Acquisition Cost (CAC) – The total cost required to acquire a new customer, including marketing and sales expenses.
CAC Payback Period – The time required to recoup the cost of acquiring a customer, typically measured in months.
Conversion Rate – The percentage of leads or trials that convert to paying customers.
4: Customer Value Metrics
Annual Contract Value (ACV) – The average annualized revenue per customer contract.
Customer Lifetime Value (LTV) – The total revenue a business can expect from a single customer account throughout their relationship.
LTV:CAC Ratio – The ratio between customer lifetime value and acquisition cost, with a healthy ratio typically being 3:1 or higher.
5: Efficiency and Profitability Metrics
Gross Margin – Revenue minus cost of goods sold (COGS), expressed as a percentage.
Net Dollar Retention (NDR) – Similar to NRR, sometimes used interchangeably.
Magic Number – Measures sales efficiency, calculated as: (Current Quarter ARR - Previous Quarter ARR) / Previous Quarter Sales & Marketing Expense.
Rule of 40 – A principle stating that a SaaS company's growth rate plus profit margin should exceed 40%.
Why These Metrics Matter
Strategic Decision Making
These metrics provide the data foundation for critical business decisions. For instance, if your CAC is rising while your LTV remains static, you might need to revisit your acquisition channels or pricing strategy.
Investor Relations
Investors in SaaS businesses look closely at these metrics to evaluate company health and growth potential. A strong NRR (typically above 110% for enterprise SaaS) signals a healthy business with satisfied customers who increase their spending over time.
Operational Excellence
Day-to-day operations benefit from metric tracking. Customer Success teams might focus on reducing churn and increasing LTV, while Sales and Marketing teams track conversion rates and CAC.
Industry Benchmarks
While benchmarks vary by company size, target market, and growth stage, here are some general targets for healthy B2B SaaS businesses:
- NRR: 110-130% (enterprise SaaS)
- GRR: 85-95%
- CAC Payback Period: 12-18 months
- LTV:CAC Ratio: 3:1 or higher
- Gross Margin: 70-85%
- Rule of 40: Above 40% (growth rate + profit margin)
Common Mistakes in Metric Tracking
- Focusing on vanity metrics rather than actionable insights
- Not segmenting metrics by customer size, industry, or acquisition channel
- Measuring too infrequently or inconsistently
- Ignoring leading indicators that could predict future performance issues
- Failing to connect metrics to specific business objectives and actions
