Gather your inputs
Have your loan amount, rate, term ready. Accuracy on the output depends entirely on the quality of these numbers. If a value is uncertain, use the most realistic figure rather than rounding aggressively.
Enter the values
Fill each field in turn. Mortgage Calculator validates ranges as you type, so an obvious typo (for example a negative balance where one cannot exist) will flag immediately.
Read the result
The output is a monthly payment, total interest, amortization, computed using standard amortization formula. Treat it as a precise answer to the question you posed, not an approximation.
