The 15 SaaS Metrics Every Founder Should Track Monthly
INTRO
High-growth SaaS companies don’t manage the business by instinct - they manage it by metrics.
The challenge isn’t access to data. Most teams are drowning in it. The real challenge is focusing on the handful of metrics that actually drive decisions around growth, hiring, pricing, and capital strategy.
Here are the 15 SaaS metrics every founder should track monthly - and how to use them effectively.
GROWTH METRICS
Growth metrics tell you whether the business is actually scaling — not just selling. For SaaS companies, recurring revenue visibility matters more than top-line volume, and leadership needs a consistent way to track expansion, momentum, and sustainability.
Resources like KeyBanc Capital Markets and Bessemer Venture Partners regularly publish helpful SaaS performance data.
1. Annual Recurring Revenue (ARR)
Your clearest indicator of scale and long-term growth trajectory.
2. Monthly Recurring Revenue (MRR)
Tracks short-term momentum and operational performance.
3. New Bookings
Shows how effectively sales is driving expansion.
Resources:

Bessemer Cloud 100 Benchmarks Report - Strong macro-level insights into leading private cloud companies and how top performers operate.
RETENTION METRICS
Retention is where SaaS businesses are truly won or lost. Strong retention compounds growth, while weak retention quietly destroys momentum. Investors and operators alike focus heavily on retention metrics because they reveal product-market fit, pricing alignment, and customer experience strength.
4. Gross Revenue Retention (GRR)
Measures revenue retained before expansion revenue.
5. Net Revenue Retention (NRR)
The most important retention metric for investors.
6. Customer Churn
Indicates product-market fit and customer success performance.
Resources:
SaaS Benchmarks Report (High Alpha/OpenView) - One of the most practical operator resources; built from hundreds of SaaS company data sets and widely used by founders.
OpenView SaaS Benchmarks Report - Deep insights into performance trends and growth/efficiency shifts across the SaaS ecosystem.
EFFICIENCY METRICS
Efficiency metrics help leadership understand whether growth is being purchased at a sustainable cost. These KPIs are especially important during hiring cycles, fundraising preparation, and periods of tighter capital markets when disciplined growth matters most.
For deeper operator-level benchmarks, the OpenView Venture Partners reports are consistently useful.
7. Customer Acquisition Cost (CAC)
Total sales and marketing spend divided by new customers.
8. Lifetime Value (LTV)
Expected revenue per customer over their lifecycle.
9. CAC Payback Period
How quickly you recover customer acquisition costs.
PROFITABILITY METRICS
As SaaS companies mature, leadership focus shifts from growth at all costs to scalable profitability. These metrics help teams understand whether growth is translating into operating leverage — and where margin pressure may be building.
10. Gross Margin
Indicates scalability and operational leverage.
11. Contribution Margin
Helps assess growth efficiency beyond gross margin.
CASH & OPERATING METRICS
Cash metrics ultimately determine how long you can execute your strategy. Even strong growth and retention cannot offset poor cash discipline, which is why experienced leadership teams monitor burn, runway, and operating efficiency closely.
For founders looking for a practical framework, Y Combinator has strong guidance around burn and runway planning.
12. Burn Rate
Net cash used monthly — critical for runway planning.
13. Runway
How long the company can operate at its current burn.
14. Magic Number
Measures sales efficiency relative to growth.
15. Rule of 40
A benchmark combining growth and profitability.
Resources:
State of the Cloud (Bessemer) - Practical founder-level perspective on burn discipline, funding cycles, and operating strategy in tougher markets.
SaaS Burn Rate Benchmarks - Helpful context on burn trends across company sizes and market cycles.
HOW TO USE THESE METRICS
The goal isn’t tracking more numbers — it’s using the right ones to drive decisions.

Review metrics monthly with leadership
Compare trends, not just snapshots
Align metrics with hiring and growth plans
Connect performance to forecasts
Metrics should inform action, not just reporting.
