$585,000 Mortgage Payment
Monthly principal & interest by interest rate and loan term.
A $585,000 mortgage at 6.50% over 30 years costs about $3,698 a month in principal and interest, and $746,136 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
- $3,698 a month on a 30-year term, with $746,136 of interest paid in total.
- $4,362 a month on a 20-year term, with $461,784 of interest paid in total.
- $5,096 a month on a 15-year term, with $332,276 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.
