SKILL.md

Calculate and interpret core SaaS revenue, retention, and growth metrics to diagnose business momentum and product-market fit.

Covers 10+ essential metrics: MRR/ARR, ARPU/ARPA, churn rate, NRR, expansion revenue, and Quick Ratio, with formulas and quality checks for each

Includes cohort analysis and revenue mix frameworks to reveal hidden trends that blended metrics obscure (e.g., cohort degradation, concentration risk)

Provides benchmarks for each metric (e.g., <2% monthly churn is great; NRR >120% is excellent) and decision rules for when to scale vs. fix retention

Highlights 10 common pitfalls: confusing revenue with profit, ignoring cohort degradation, treating all churn equally, and misinterpreting blended metrics

Purpose

Master revenue and retention metrics to understand SaaS business momentum, evaluate product-market fit, and make data-driven decisions about growth investments. Use this to calculate key metrics, interpret trends, identify problems early, and communicate business health to stakeholders.

This is not a business intelligence tool—it's a framework for PMs to understand which metrics matter, how to calculate them correctly, and what actions to take based on the numbers.

Key Concepts

Revenue Metrics Family

The "top-line" metrics that measure how much money the business generates.

Revenue — Total money earned from selling products/services before expenses. The "top line" of the income statement.

Why PMs care: Every feature should connect to revenue (direct or indirect). If you can't articulate revenue impact, prioritization becomes impossible.

Formula: Sum of all customer payments in a period

Benchmark: Growth rate matters more than absolute number (context-dependent by stage)
