Frequently Asked Questions
What is the most important SaaS metric?
While it depends on your growth stage, Monthly Recurring Revenue (MRR) and Net Revenue Retention (NRR) are generally considered the most critical. MRR tracks your baseline growth, while NRR indicates if your existing customer base is compounding in value despite churn.
Should I calculate LTV and CAC together?
Yes. Calculating LTV or CAC in isolation provides an incomplete picture. You must calculate them together to find your LTV:CAC ratio. An ideal ratio for a healthy, scalable SaaS business is 3:1 or higher, meaning a customer brings in three times the gross profit it cost to acquire them.
What is a healthy churn rate?
A healthy churn rate depends on your target market. For B2B Enterprise SaaS with high annual contract values, you should aim for less than 1% monthly logo churn. For SMB or B2C SaaS, a monthly churn rate between 3% and 5% is considered standard and healthy.
How often should SaaS metrics be reviewed?
Operational metrics like CAC, ROAS, and new signups should be reviewed weekly by marketing and sales teams. High-level financial metrics like MRR, Churn Rate, and LTV should be calculated and reviewed monthly for board reporting and macro-strategic planning.
Which SaaS metric do investors care about most?
Most SaaS investors evaluate several metrics together, including MRR growth, churn rate, CAC, LTV, and the LTV:CAC ratio. Healthy unit economics are often more important than rapid growth alone.
