Your total interest on a $600,000 mortgage

On a 25-year mortgage with a 4.5% fixed interest rate, you’ll pay approximately $396,251.32 in interest over the life of your mortgage. That’s two-thirds of what you borrowed in interest.

If you instead opt for a 15-year mortgage, you’ll pay approximately $223,897.54 in interest over the life of your mortgage — or almost half of the interest you’d pay on a 25-year mortgage.

Amortization schedule

Your amortization period is the total number of years you have to pay off your mortgage in full, including both the balance and interest.

When you sign on for a mortgage, you agree to pay the principal amount and the interest over the life of the mortgage. Your interest rate is applied to your principal amount, and as you pay down your principal amount, the amount you pay in interest changes. Amortization means that at the beginning of your mortgage, a big percentage of your payment is applied to interest. With each subsequent payment, you pay more toward your principal amount and less toward interest.

Below, you can estimate your monthly mortgage repayments on a $600,000 mortgage at a 3.5% fixed interest rate with our amortization schedule over 15- and 25- years.

At a 3.5% fixed-rate over 15-years, you’d pay approximately $4,281.86 monthly. Over the course of a year, that’s a total of $51,382.32 in mortgage payments. In the table below, compare how much you would pay toward both interest and the principal amount each year.
