This mortgage amortization calculator shows your mortgage payment schedule broken down by interest and principal payments. On the graph, you will see two lines that represent your total mortgage payment. In the early years of your mortgage, the majority of your monthly payment is applied to interest. As time goes by, more of your mortgage payment will be applied to your principal. You can hover over any point on the graph to view your monthly principal & interest payment. Try playing with your preferred interest rate to see how your monthly payment could be impacted by today’s record low mortgage rates. Expand the “See How Extra Payments Affect Your Loan” section of our mortgage amortization calculator to add an additional monthly or annual payment to the principal and see how much interest you can save over the life of your loan.
