7 SaaS Metrics Every Indie Founder Should Track From Day One

Most early-stage founders track too few metrics or too many. Here are the seven that give you a complete picture of your SaaS business health with minimal overhead.

• MRR — your monthly revenue baseline. Track it weekly, not monthly.
• New MRR — revenue from new customers this month. Tells you if your acquisition is working.
• Churned MRR — revenue lost from cancellations. The number most founders ignore too long.
• Monthly churn rate — churned customers ÷ starting customers. Your retention signal.
• Activation rate — percentage of signups who reach your core value moment. Your onboarding signal.
• MRR growth rate — month-over-month MRR change in percentage. Your momentum signal.
• LTV:CAC ratio — are you building a sustainable acquisition engine?

What to do with these numbers

You do not need fancy dashboards to track these. A simple spreadsheet updated weekly is enough to spot trends early. The goal is not to have pretty charts — it is to notice when something is off before it becomes expensive to fix.

When to add more metrics

Once you have customers and revenue, you can layer in expansion MRR, NRR, activation cohorts, and payback period. But in the first six months, these seven are everything you need to run a clear-headed business.
