How to use this Customer Growth Rate Calculator

Enter your current SaaS metrics, then review the result, secondary metrics, and benchmark interpretation. This calculator is designed for fast planning rather than formal accounting.

Formula

Customer Growth Rate = Net New Customers ÷ Starting Customers × 100

The important point is consistency. Use the same revenue definition, time period, and customer definition every time so the metric remains comparable month to month.

Benchmark notes are directional. A healthy metric can still hide poor cohort quality, weak cash flow, or low gross margin.
