Finance Calculators: EMI, Interest, Tip, Discount, Tax

Money decisions are easier when you can see the arithmetic. These calculators cover everyday questions — what a loan will cost per month, how savings compound, what a sale price really is, how to split a bill — and show the formula and a worked example next to the result.

The loan calculator uses the standard amortised-payment (EMI) formula used by banks worldwide; the interest tools use textbook compound and simple interest with a selectable compounding frequency. Amounts are formatted in the currency you choose, but the maths is currency-neutral.

Always compare our estimates with the official quote from your lender or retailer: processing fees, insurance, taxes, and rounding conventions can move the final figure.
