About Us

ToolMitra is a free, all-in-one collection of online calculators, everyday tools, daily brain games and fun quizzes. We started it because the tools people use most — a SIP calculator, an EMI calculator, an age calculator — were often buried in slow, cluttered pages. We wanted one place where each tool loads instantly on a budget phone, gives a clear answer, and explains how that answer was worked out.

Our principles

• Fast and mobile-first. Pages are lightweight and designed for phones first, so they work well even on slow connections.
• Private by design. Calculations happen in your browser. We don't ask you to sign up and we don't store what you type into our tools.
• Transparent. Every calculator explains the formula it uses, with a worked example, so you can check the result yourself.
• Free. The site is supported by advertising, which keeps every tool free for everyone.

Accuracy and advice

We test our calculators carefully and update them when rules change (for example, new income tax slabs). Still, results are estimates for educational purposes and are not financial, tax, legal or medical advice. Please read ourDisclaimer for details.
