SaaS Metrics

Q: How do I know the SaaS Metrics output is good?

The skill verifies itself against its own quality checks: NRR excludes new MRR (it measures the existing base only) — the most-botched definition; GRR is capped at 100% (it can't exceed retention of what you had); Each metric is shown against its standard benchmark; The formulas used are stated, so the numbers are comparable across reports.

🔵 Stable🕐 updated 2026-10-06 🔷 SkillSpec L3 ⚙ ships an executable helper pm-calculators

Compute the core SaaS metrics — MRR/ARR, growth, NRR/GRR, churn, quick ratio, magic number — from your numbers. Use when asked to calculate SaaS metrics, MRR/ARR, net revenue retention, the quick ratio, or to build a SaaS metrics snapshot for a board/investor update. Produces a computed metrics dashboard with each value, its benchmark, and a one-line read on what it means.

📚 Based on SaaS metrics definitions (Bessemer / a16z / KeyBanc)

What to give it

▸Starting MRR — and the month's movement: new, expansion, contraction, churned MRR.

▸Customer counts — (start, churned) if you want logo churn too.

▸S&M spend — (prior period) if you want the magic number.

▸Or just paste what you have — the skill computes what the inputs allow and flags the rest.

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓NRR excludes new MRR (it measures the existing base only) — the most-botched definition

✓GRR is capped at 100% (it can't exceed retention of what you had)

✓Each metric is shown against its standard benchmark

✓The formulas used are stated, so the numbers are comparable across reports

✓Metrics that can't be computed from the given inputs are flagged, not guessed

⚠️ What it refuses to do

Do not include new customers in NRR — that's a different (and misleadingly flattering) number

Do not mix monthly and annual figures without converting — label MRR vs ARR clearly

Do not report a metric without its definition — "120% retention" is meaningless without the formula

Do not vanity-pick metrics — show churn and contraction alongside the growth numbers

Do not present computed values to false precision — round sensibly and flag assumptions
