SaaS Metrics Coach Skill

Overview

Production-ready SaaS metrics toolkit for calculating MRR/ARR, analyzing cohort retention, and evaluating unit economics. Designed for SaaS founders, finance teams, and growth operators who need precise subscription revenue analysis without spreadsheet gymnastics.

Clarify First

Before calculating, confirm these inputs. If any is unknown or vague, ASK — do not assume:

• Which metric set — MRR/ARR growth, cohort retention, or unit economics (selects the script and the input format: subscription CSV, activity CSV, or metrics JSON)
• Reporting period + currency handling — the window and how multi-currency MRR is normalized (changes every revenue and churn figure)
• Gross margin — the margin to apply (drives LTV and CAC payback; LTV = ARPU x margin / churn)
• Churn definition — gross vs. net, logo vs. revenue (changes churn rate, NRR, and the health-flag verdict)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.
