Why use these calculators?
Every result shows the maths behind it: the formula, the numbers you entered, and a worked example you can check. Nothing is hidden, and nothing is made up. The rates in our examples are labelled as examples — this site does not publish live rates, because rates change and depend on your credit and your lender. Enter the rate your lender quotes you, and the calculators do the rest.

Sources and method. Standard loan amortization formula: monthly rate = annual rate / 12; monthly payment = P × r(1+r)n / ((1+r)n − 1). Simple interest I = P × r × t; compound interest A = P(1 + r/n)nt. Rates in the examples on this page are examples only, not live market rates. Results are estimates, not financial advice.
Estimate, not financial advice. This calculator uses the numbers you enter and the standard amortization formula. Your lender’s figures, fees and payoff rules can differ. Check the loan agreement and talk to a financial professional before you borrow.
