You can ask your lender for an amortization schedule, but this might not be as helpful if you're looking to see how extra payments could impact that schedule.
1: First, multiply the number of years in your mortgage term by 12 (the number of months in a year) to get the total number of payments you will make. For example, a 30-year mortgage will have 360 payments: 30 x 12 = 360. 2: Next, divide your mortgage debt by the number of repayments you will make.
