We believe everyone should be able to make financial decisions with confidence. And while our site doesn’t feature every company or financial product available on the market, we’re proud that the guidance we offer, the information we provide and the tools we create are objective, independent, straightforward — and free.
So how do we make money? Our partners compensate us. This may influence which products we review and write about (and where those products appear on the site), but it in no way affects our recommendations or advice, which are grounded in thousands of hours of research. Our partners cannot pay us to guarantee favorable reviews of their products or services. Here is a list of our partners.

NerdWallet writers and editors are experts in their field and come from a range of backgrounds in journalism and finance. We adhere to the highest editorial standards to ensure our readers have the information necessary to make financial decisions with confidence.

An interest-only mortgage typically has a fixed rate and fixed monthly payments for an initial period — say, the first 10 years. These initial payments pay down only the interest on the loan, not the principal. At the end of the initial period, the rate changes from fixed to adjustable, and the monthly payments increase, becoming payments toward principal and interest for the remaining loan term.
This calculator helps you compare the payments during the interest-only period to the payments on a fully amortizing mortgage.
