SaaS & Startup Unit Economics
Every fundable SaaS business is a story told in unit economics. This suite covers the metrics founders, growth marketers, and finance leads use to prove that story to themselves and to investors — from acquisition cost, lifetime value, and the LTV:CAC ratio to churn, burn, runway, retention, and go-to-market efficiency. Each calculator runs instantly in your browser, with no signup and no cost, so you can pressure-test a growth model, prep for a board meeting, or sanity-check a term sheet in minutes.
