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.
