We believe that useful tools should be free and accessible to everyone. That's why every calculator on this site is completely free to use, with no account required, no email signup, and no hidden paywalls.
In a world where most websites track your every move and bombard you with ads, we chose a different path. Your privacy matters. All calculations happen right in your browser - we never see your data, and we never will.
Each calculator is designed with real-world use cases in mind. Whether you're a freelancer figuring out your day rate, calculating your daily calories, planning a loan, or just trying to split a dinner bill, we've got you covered with 23 calculators across 7 categories.
