How CACulator works
From free calculators to board-ready operating intelligence.
CACulator is not just a calculator site. It is a workflow for SaaS operators who need defensible numbers, cohort context, and investor-ready packaging.
Operating intelligence
Calculate and defend CAC, LTV, NRR, burn multiple, Rule of 40, and 23 more core SaaS metrics with transparent, versioned formulas and worked examples on every page.
Dual-cohort benchmarking
Compare against peer cohorts (p25 / p50 / p75) by stage, ARR, ACV, and GTM motion, and for firms against the rest of your own portfolio. Sample-gated and methodology-published.
Board-meeting workflow
Pre-board Q&A anchored to each metric, Decisions Requested, readiness dashboards, period deltas, and follow-ups, so meetings are shorter and more strategic.
AI narrative, grounded in your numbers
AI drafts the executive summary, highlights, challenges, and decisions from your selected metric snapshots. Never invented numbers, with evidence shown before generation.
The board meeting, not just the board book
Resolve the board's questions before the meeting starts.
Investors and operators thread questions anchored to a specific metric, “Why did NRR drop to 104%?” is pinned to the Q2 NRR number, not buried in email. Mark threads resolved, draft the agenda from what's still open, and carry operating-partner follow-ups into the next period. The result: shorter, more strategic board meetings built on numbers everyone can see.
