Finance Calculators

These calculators cover the money maths that turns up in business studies, accounting and personal finance classes. They apply standard textbook formulas to the numbers you enter. They are for learning and for rough planning, and they are not financial advice: a real loan, salary or investment comes with fees, taxes and terms that a formula does not know about.

The depreciation calculator spreads the cost of an asset over its useful life. The future value of an annuity calculator shows what a series of equal payments grows to at a given interest rate. The mortgage repayment calculator works out the regular payment on a loan and how much of it is interest. The hourly to salary converter turns an hourly wage into weekly, monthly and yearly pay. The home appreciation calculator projects a value forward at a steady yearly rate, and the percent growth calculator measures growth between a starting and an ending value. A page of financial calculators collects several small loan and investment tools in one place.

If the question is about percentages in general, for example a discount or a change in a test score, the percentage calculator and the percent change calculator in the arithmetic section show every step.
