Key SaaS Metrics Every Founder Should Track

Understand the data behind growth. These metrics guide strategic decisions for retention, scaling, and long-term profitability.

Essential SaaS Metrics

1. Net Promoter Score (NPS)

Measures customer satisfaction and loyalty. A higher NPS means happier users likely to recommend your product.

2. Customer Acquisition Cost (CAC)

The total cost to acquire a new customer. Tracking CAC helps optimize your marketing and sales efficiency.

3. Expansion Revenue

Revenue growth from existing customers via upgrades, add-ons, or upsells — a key indicator of product-market fit.

4. Churn Rate

The percentage of customers who stop using your service. Reducing churn increases lifetime value and growth potential.

5. LTV/CAC Ratio

Compares customer lifetime value to acquisition cost. A healthy ratio (above 3:1) means your growth is sustainable.
