$12,495,000 Mortgage Payment
Monthly principal & interest by interest rate and loan term.
A $12,495,000 mortgage at 6.50% over 30 years costs about $78,977 a month in principal and interest, and $15,936,684 in interest over the life of the loan.
Early payments are mostly interest: in the first year only a small slice of each instalment reduces the balance. That is why a shorter term saves so much — the rate is similar, but the interest has far less time to compound.

- $108,845 a month on a 15-year term, with $7,097,077 of interest paid in total.
