About ToolBandhu

ToolBandhu is a small, independent website offering free online calculators and utilities. There is no signup, no trial and no paywall — you open a tool and use it.

Six calculators are live right now: Age Calculator, EMI Calculator, GST Calculator, Loan Calculator, Percentage Calculator and SIP Calculator. Other categories such as PDF tools, image tools, government checklists and AI helpers are still in development and are marked as coming soon on the homepage.

The calculators run entirely in your browser. The numbers you type are used to render the result on your screen and are not sent to our servers or stored by us.

Suggestions, corrections and bug reports are welcome at support@toolbandhu.com.
