What refinancing could save in Index

Index owners with a mortgage pay a median $1,545 a month for their mortgage, taxes, insurance and utilities, about 15.5% of their household income.

Say you owe $348,000, about 60% of the median home value here, on a 30-year loan at 8.11%. Refinancing into a new 30-year loan at this week's average of 7.11% would cut principal and interest from $2,580 to $2,341, saving about $239 a month.

Closing costs often run 2% to 5% of the loan. At 3%, about $10,400, the savings would cover the costs in about 44 months, so refinancing pays off if you keep the home longer than that.

A 15-year loan at 6.45% would raise the payment to $3,022, but you'd pay $298,825 less interest than on the new 30-year loan.

The average 30-year rate is 0.87 percentage points higher than a year ago, when it was 6.24%.

Refinancing a $348,000 balance
Current loan at 8.11%, 30 years$2,580
New 30-year loan at 7.11%$2,341
New 15-year loan at 6.45%$3,022
Monthly savings with the new 30-year loan$239

Principal and interest only; taxes and insurance stay the same.
