Free online finance calculators
These finance calculators cover the everyday money questions: what a home or car loan EMI works out to, how much tax you owe under the old and new regimes, and how interest adds up over a few years. Each one uses the same reducing-balance formulas your bank uses and recalculates the moment you change a number.
They are handy when you are planning a big purchase, working out a monthly repayment, or checking your take-home salary. There is nothing to install and nothing to pay, and the maths happens in your browser, so the figures you enter never leave your device.
