About startup & SaaS calculators
Early-stage companies live and die by a few numbers. These calculators cover recurring revenue (MRR and ARR), churn, customer acquisition cost, customer lifetime value, the LTV to CAC ratio, CAC payback and the Rule of 40, plus the ownership side of fundraising: equity dilution across rounds, a simple cap table, SAFE and convertible note conversion, and the venture capital method of valuation. Definitions of these metrics vary between companies, so each page states the formula it uses. Results are estimates, not valuations or advice.
