About Interest Only Mortgage Calculator

This interest only mortgage calculator lets you specify the length of the interest only period. It will show the amount of the interest only payment and the the total cost of a loan.

The interest-only mortgage is a specific type of mortgage when the first few years only interest is paid, and the body of the debt remains the same. Usually, the period of payment of percents only varies from 3 to 10 years in the US. The interest-only mortgage can be convenient if the borrower can not afford to pay the fully amortized payment for some reasons. For example, this can be helpful for a student who ends his education at a university. Or, such a mortgage can be borrowed by a person expecting a significant inflow of money in the future.

Use this mortgage calculator and fully amortized payment will not be a surprise for you.
