Finance calculators

Ten calculators for borrowing, saving, pay, tax and pricing. Change any number and the result updates straight away.

Money decisions come down to a few formulas: how much interest a loan costs, how fast savings grow, and what price leaves you a profit. These calculators show the result and the working, so you can see why the number is what it is.

Every finance calculator lets you choose your currency, and nothing you type is sent anywhere. The figures are estimates for planning. Your lender or bank has the final numbers.
