100% Private — Zero Data Sent
Every single calculator on this site runs entirely inside your browser. We do not have a backend that receives your inputs. No number you type is ever transmitted to a server, stored in a database, or seen by us. Your financial data stays exactly where it belongs — with you.
This also means the calculators work offline once the page has loaded. Your data, your device, your control.
Our Indian Finance Suite
We built a dedicated suite of calculators for India — covering FY 2026-27 tax slabs, government scheme rates (PPF at 7.1%, SSY at 8.2%, SCSS at 8.2%), Indian loan products, GST, stamp duty, and more. Rates are reviewed and updated regularly against official government sources.
No Accounts Required
You don't need to sign up, log in, or give us your email to use any calculator. Everything is freely accessible. An optional sign-in feature stores calculation history locally in your browser — nothing leaves your device.
