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.
✅ 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
