Your total interest on an $800,000 mortgage

On a 30-year $800,000 mortgage with a 7.00% fixed interest rate, you’ll pay $1,116,071 in interest over the life of your loan. That’s about two-thirds of what you borrowed in interest. If you instead opt for a 15-year mortgage, you’ll pay $494,313 in interest over the life of your loan — about half of the interest you’d pay on a 30-year mortgage.

Amortization schedule

When you take out a mortgage, you agree to pay the principal and interest over the life of the loan. Your interest rate is applied to your balance, and as you pay down your balance, the amount you pay in interest charges.
Amortization means that at the beginning of your loan, a big percentage of your payment is applied to interest. With each subsequent payment, you pay more toward your balance.
Estimate your monthly loan repayments on an $800,000 mortgage at a 7.00% fixed interest with our amortization schedule over 15 and 30 years.
