SaaS metrics · checked 11 November 2026
Track MRR growth, churn, gross margin and CAC payback early; investors now lead with CAC payback and net revenue retention.
Five numbers are enough in the first years: new ARR, gross and net revenue retention, CAC payback, pipeline coverage and win rate. The magic number, new annualised revenue per dollar of sales and marketing spend, helps decide when to hire more reps. For an AI product, gross margin becomes a first-order metric once inference costs move with usage.
