Who chooses a 15-year mortgage

The 15-year loan is the classic fast-payoff mortgage: rates are usually lower than 30-year rates and equity builds quickly. Buyers who can handle the higher payment often choose it to be mortgage-free before retirement or before children reach college age.

15-year facts for a $320,000 loan

At 5.9%, a 15-year loan on $320,000 costs $2,683.08 a month. Interest totals $162,956, or 51% of the loan, and half the principal is repaid after about 9.2 years.

What each 5.9% ± 1 point does to the payment

A one-point change in your mortgage rate moves the payment on $320,000 by roughly $175.31 a month and the lifetime interest by about $31,555 over 15 years. That is why it pays to compare several lenders on the same day.

Down payment and PMI on a $400,000 home

With less than 20% down, lenders charge private mortgage insurance (PMI), commonly 0.3% to 1.5% of the loan per year. This page assumes 0.6%. PMI usually ends when you reach 80% of the home's original value, which you can reach sooner with extra payments.

Down paymentLoan amountPMI / monthTotal monthly payment
5% ($20,000)$380,000$190.00$3,867.83
10% ($40,000)$360,000$180.00$3,690.14
20% ($80,000)$320,000$0.00$3,174.75

What income does a $400,000 home need?

Lenders often look at a front-end ratio of about 28% of gross income for housing costs. A total payment of $3,174.75 implies a gross income near $136,000 a year, and lenders also weigh your other debts, which usually must keep total payments under about 36% to 43% of income.

In the first year, $18,514 of your payments goes to interest and only $13,683 to principal, so equity builds slowly at first.

How fast you build equity

Equity here is the home price minus the loan balance, assuming the price stays flat. Appreciation, if any, would add to it.

Frequently asked questions

What is the monthly payment on a $320,000 mortgage?

How can I pay off my mortgage faster?

Add extra principal each month, make one extra payment a year, or refinance to a shorter term. Use the extra payment field above to see the interest you would save.

Are these numbers a loan offer?

No. They are estimates from standard formulas. Your lender’s quote can differ because of fees, rounding, escrow and your credit profile.
