Which SaaS Metrics Should I Track?
There are dozens of SaaS metrics, and the right handful depends on your company. Describe it in a sentence or two and get the metrics that matter most right now, why they matter for you, and how to calculate each one correctly.
How it works
An automated model (TypeSafe AI) reads your description and classifies five things: funding stage, how customers buy, who you sell to, your main goal, and how you charge. When it isn't sure, it asks you instead of guessing. It does not write the recommendations: those come from a fixed playbook of weights and explanations based on 4NLab's experience, so the same profile always gets the same list. The result is educational, not fundraising or financial advice. See the Terms of Use and Disclaimer.

Your first month of metrics: a checklist
- At the start of the month, record paying customers and MRR. Leave out trials and free accounts.
- Convert every plan to a monthly amount: divide annual plans by 12, and leave setup fees and one-off services out.
- At month end, count cancellations among the starting customers for customer churn. Report customers who came back separately; don't net them against churn.
- Split the change in MRR into new, expansion, contraction, churn and reactivation, which gives you GRR and NRR for the starting customers.
- Record sales and marketing spend, including sales salaries, and new paying customers for CAC.
- Note your cash balance and net burn to track runway.
Where to start at each stage
Before sales motion, customers and goal are taken into account, these are the playbook's starting points:
Bootstrapped
- Customer churn: Customer churn is the share of starting customers you lose each period, usually the earliest sign of a retention problem.
- MRR: MRR is your recurring revenue each month; its month-over-month change is the clearest signal of growth.
- Free cash flow: Free cash flow is the cash your business actually generates after operating costs and capital spending.
- CAC payback: CAC payback is how many months of gross profit it takes to earn back what you spent to win a customer.
- Gross margin: Gross margin is how much of each revenue dollar is left after the cost of delivering your product.
- ARPA: ARPA is average monthly revenue per account; it shows whether growth comes from more customers or bigger ones.
Pre-seed

- Runway: Runway is how many months your cash lasts at your current net burn.
- Product-market fit: Product-market fit signals show whether a specific group of customers truly needs what you've built.
- MRR: MRR is your recurring revenue each month; its month-over-month change is the clearest signal of growth.
