30-year fixed mortgages

The average 30-year fixed-mortgage rate is 4.30 percent, a decrease of 1 basis point over the last week. A month ago, the average rate on a 30-year fixed mortgage was unchanged, at 4.30 percent.

At the current average rate, you’ll pay a combined $494.87 per month in principal and interest for every $100,000 you borrow. That represents a decline of $0.59 over what it would have been last week.

You can use Bankrate’s mortgage calculator to figure out your monthly payments and see the effect of adding extra payments. It will also help you calculate how much interest you’ll pay over the life of the loan.

15-year fixed mortgages

The average 15-year fixed-mortgage rate is 3.75 percent, up 1 basis point over the last week.

Monthly payments on a 15-year fixed mortgage at that rate will cost around $727 per $100,000 borrowed. That may put more pressure on your monthly budget than a 30-year mortgage would, but it comes with some big advantages: You’ll save thousands of dollars over the life of the loan in total interest paid and build equity much faster.

5/1 ARMs

The average rate on a 5/1 ARM is 4.10 percent, ticking down 4 basis points over the last 7 days.

These types of loans are best for those who expect to sell or refinance before the first or second adjustment. Rates could be substantially higher when the loan first adjusts, and thereafter.

Monthly payments on a 5/1 ARM at 4.10 percent would cost about $483 for each $100,000 borrowed over the initial five years, but could climb hundreds of dollars higher afterward, depending on the loan’s terms.
