Calculators
Money, health and everyday maths — answered as you type
These are the numbers people need before making a decision: what an EMI really costs over its full term, how much GST to add, what a salary becomes after deductions, how many calories a day suits your body. Every calculator shows its result the moment you have entered enough to compute one, explains the formula below the fold, and runs entirely in your browser — so nothing you type is sent anywhere.

What people use these for
- Work out a loan or mortgage payment before you commit to it
- Add or remove GST, or convert a CTC into take-home pay
- Check a health number — BMI, calories, body fat — against the standard method
- Settle an everyday question: percentages, dates, fuel cost, unit price
Frequently asked questions
- Are these calculators accurate enough to act on?
- Each one states the method it uses and sticks to the standard version of it — reducing-balance for EMI, Mifflin-St Jeor for calories, the Devine formula for ideal weight, quarterly compounding for fixed deposits because that is the convention Indian banks follow. Where a figure depends on something we cannot know, such as a lender's processing fee or your employer's exact deduction structure, the page says so rather than quietly guessing. Treat the result as the arithmetic done correctly, and confirm anything contractual with the institution.
- Do the health calculators work in pounds and feet?
- Yes. Eleven of them — BMI, BMR, calories, TDEE, body fat, ideal weight, protein, water intake, the diet chart and the walking and pace calculators — take kilograms and centimetres or pounds with feet and inches, and answer in the units you chose. The setting is picked from your browser's region on your first visit and remembered after you change it, so a reader in Ohio and a reader in Ludhiana each see numbers they can act on without converting anything by hand.
- Is anything I type stored or sent anywhere?
- No. Every calculator here computes in your browser using JavaScript that ships with the page, so salary figures, loan amounts and body measurements never travel over the network. The straightforward way to check is to load a page, disconnect from the internet, and keep using it — it works, because there is nothing on the other end to call.
- Which calculator should I use for a loan?
- Start with the EMI calculator if you only want the monthly figure or you want to plan prepayments — it takes a lump sum repeated yearly and shows what it saves. Use the home, car, personal or education loan pages instead when the loan type changes the question: education loans have a moratorium before repayment starts, car loans raise the question of owing more than the car is worth, and home loans run long enough that the interest can exceed the amount borrowed.
