Calculate and interpret SaaS metrics for founders: MRR, ARR, NRR, GRR, churn, CAC payback, LTV:CAC, burn multiple, Rule of 40, cohort retention, and scenario models. Use when building investor updates, dashboards, board materials, pricing decisions, or growth diagnostics.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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`. ## Authoritative Foundations - **David Skok (forEntrepreneurs).** LTV:CAC, CAC payback, fully loaded S&M — canonical formulas for diligence. - **Jason Lemkin / David Sacks.** Burn multiple = net burn ÷ net new ARR; primary capital-efficiency gate at Series A+. → `references/david-sacks-saas-metrics.md` - **Bessemer Cloud Atlas.** Rule of 40, stage benchmarks, PLG essays. → `references/bessemer-cloud-atlas.md` - **SaaS Capital / KeyBanc.** Stage benchmarks for private B2B SaaS. …

How to install
mdr add leadmagic/gtm-skills/saas-metrics-calculator@sha256:a4f06e9b96354a6eThe line at the top of this page pins the label v1.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
