About

Everyday Tools is a collection of free calculators and browser-based utilities built for people in India: loan EMIs, investments, salary and tax, everyday maths, health estimates and small business pricing.

Every calculator explains its formula, shows a worked example in rupees and lists its assumptions, so you can understand the number and not just copy it.

Calculations run inside your browser. The amounts you type are not sent to our servers, because the site has no server-side processing and no database.

Pages that depend on rules that change, such as income tax slabs or deposit schemes, name the financial year they apply to, link to the official source and show the date they were last reviewed.

If you spot an error, please tell us through the Contact page so we can check and correct it.

We are not a bank, lender, broker, tax advisor or medical provider. Results are estimates for planning and learning. See the Disclaimer for details.
