BestSaaSMetrics
BestSaaSMetrics is a free interactive SaaS unit economics calculator focused on CAC payback, LTV:CAC, and cashflow modeling. It runs entirely client-side and includes preloaded benchmark ranges for eight SaaS business models: Enterprise B2B, Bootstrapped Micro-SaaS, PLG Self-Serve, Fintech, Healthcare, EdTech, SalesTech, and Developer Tools. The tool supports selecting a model and entering CAC, ARPA, gross margin, monthly churn, and sales cycle length, then outputs payback in months, LTV:CAC ratio, customer lifetime, monthly net per account, and a 36-month cumulative cashflow trajectory. It applies ASC 606-adjusted calculations where payback is computed as CAC divided by (ARPA multiplied by gross margin percentage), and displays the formula with live substitutions. Benchmarks are presented as top-quartile, median, and bottom-quartile ranges, referencing a 2026 dataset attributed to Bessemer Venture Partners, KeyBanc Capital Markets, and public SaaS filings. The site also includes educational content defining CAC payback and offering strategies to shorten it. The web page is monetized through advertising and sponsored placements for SaaS billing and growth capital services, but the core calculator itself is free and requires no sign-up. It provides interactive scenario comparison, save/share functionality, and PDF export for analysis reporting.
