Growth metric
calculators.

Every calculator here does the same job: run your own numbers, then show you where they land against real software-industry benchmarks. The set covers the growth, GTM, and SaaS metrics that decide budgets and board slides: CAC, LTV, LTV:CAC, CAC payback period, MRR and ARR growth, churn, retention, activation, NPS, DAU/MAU stickiness, and more. Each page uses the practitioner version of the formula, the one that survives a finance review, not the flattering shortcut half the internet still publishes.

Each calculator pairs the live tool with the definition, the exact formula, a worked example, and a median/good/great benchmark table broken out by industry (SaaS, Fintech, Dev Tools, AI/ML, E-commerce, Healthtech, Martech) with the source named. Browse alphabetically for a specific metric, or sort by most read to see which calculators other operators reach for. Every benchmark traces back to a named primary report, so you can defend the number, not just quote it.
