About calcugator

Calcugator is a free, growing collection of calculators for everyday life, health, home projects, finance, school, and more. Every calculator runs entirely in your browser: nothing you type is ever sent to a server, and there's no account to make. New calculators get added over time, organized by category so the site stays easy to browse instead of turning into one long, overwhelming list.
