Mortgage Calculator
Work out the monthly payment on a home loan by entering the loan amount, annual interest rate and term in years. This mortgage calculator uses the standard fixed-rate amortization formula, so the figure it returns is the principal-and-interest payment a lender would quote for that loan. It also breaks down the total interest you will pay across the whole term and the total amount repaid, then builds a year-by-year amortization schedule showing how each payment splits between interest and principal and how your balance falls over time. Seeing that split makes it obvious why early payments are mostly interest. Adjust the rate or term to compare scenarios. Taxes and insurance are not included. Everything runs locally in your browser.
