About ToolHub

ToolHub was built around one idea: the calculation you need should take you seconds, not a search through five ad-choked pages to find a working tool.

What we build

Every calculator on ToolHub runs entirely in your browser. We publish the formula behind each tool alongside the result, so you're never just trusting a black box — you can check the math yourself, or use the same formula in a spreadsheet if you'd rather.

How we make money

ToolHub is supported by display advertising placed around — never inside — the calculators themselves. We don't require an account, and we don't sell the numbers you type in, because we don't store them.

Our standards

• Every formula is checked against standard published references (RBI/SEBI guidance for Indian finance tools, WHO guidance for health tools).
• Results are labeled as estimates — for binding decisions (loan contracts, medical diagnoses, tax filing) we tell you to confirm with a licensed professional.
• New tools are added based on what people actually search for.
