SaaS Metrics Calculator

Overview

SaaS metrics answer whether your business model works. The mistake: cherry-picking the metric that makes you look good (usually ARR growth) and ignoring the metric that tells the truth (usually churn or CAC payback). This skill calculates all key metrics from minimal inputs, applies stage-aware benchmarks, diagnoses which lever to pull first, and produces board-ready, investor-ready output. Every formula is documented. Every benchmark is sourced. For exit weight by buyer type, load references/metric-definitions-exit-weight.md.
