This interest-only mortgage calculator will help you find out what payment you will pay based on the interest-only payback portion for your loan principal. This result will likely be lower than a standard mortgage payment as it calculates your obligation for the interest-only portion of the mortgage, rather than the principal and interest. To use the calculator simply enter the loan principal amount and loan interest rate and the interest-only mortgage calculator will calculate the payment amounts for you.
