$30,000,000 Mortgage Payment
Monthly principal & interest by interest rate and loan term.
A $30,000,000 mortgage at 6.50% over 30 years costs about $189,620 a month in principal and interest, and $38,263,348 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.

- $261,332 a month on a 15-year term, with $17,039,798 of interest paid in total.
