$730,000 Mortgage Payment
Monthly principal & interest by interest rate and loan term.
A $730,000 mortgage at 6.50% over 30 years costs about $4,614 a month in principal and interest, and $931,076 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.
Choosing a term
- $4,614 a month on a 30-year term, with $931,076 of interest paid in total.
- $5,443 a month on a 20-year term, with $576,243 of interest paid in total.
- $6,359 a month on a 15-year term, with $414,634 of interest paid in total.
- Property tax, homeowners insurance, PMI and HOA dues are not included — a common reason a real payment lands 20-30% above the figure shown here.
