Several key refinance rates declined today.

Nationwide averages for 30-year fixed and 15-year fixed refinances both trended down. The average rate on 10-year fixed refis, meanwhile, also decreased.

Compare refinancing rates in your area now.

30-year fixed refinance

The average 30-year fixed-refinance rate is 4.37 percent, down 3 basis points compared with a week ago. A month ago, the average rate on a 30-year fixed refinance was higher, at 4.44 percent.

At the current average rate, you’ll pay $498.99 per month in principal and interest for every $100,000 you borrow. Compared with last week, that’s $1.77 lower.

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 refinance

The average rate for a 15-year fixed refi is 3.77 percent, down 4 basis points over the last week.

Monthly payments on a 15-year fixed refinance at that rate will cost around $729 per $100,000 borrowed. That’s clearly much higher than the monthly payment would be on a 30-year mortgage at that rate, but it comes with some big advantages: You’ll come out thousands of dollars ahead over the life of the loan in total interest paid and build equity much more quickly.

10-year fixed refinance

The average rate for a 10-year fixed-refinance loan is 3.69 percent, down 3 basis points since the same time last week.

Monthly payments on a 10-year fixed-rate refi at 3.69 percent would cost $999.20 per month for every $100,000 you borrow. That hard-to-swallow monthly payment comes with the benefit of paying even less interest over the life of the loan than you would with a 15-year term.
