First, run the calculation as a regular 30-year mortgage, and have the calculator determine what the payment should be. In the "Summary" section, make note of what the "Interest Only" payment is. Now enter this amount in the "Payment Amount" field, plus whatever extra you want to add. Set the "Number of Regular Payments" to 120 (for 10 years), be sure the "Show Amortization Schedule" box is checked, and click "Calculate". The "Balloon Payment" field will now contain the expected principal payment *plus* another period's interest payment. If you scroll down the amortization schedule to line 120, you'll see the remaining principal in the far-right column. Now you can use the remaining principal to do a fresh 20-year amortization, if you'd like. Bret You can do this calculation in pieces.

Printing is really a browser function, and try as I might, I haven't been able to get my browser to duplicate the blank pages you've described. Still, I've tweaked the printing CSS further just in case. Can you try a different browser to see if it does the same thing? (Neither Firefox nor IE8 under Windows7-64 produce blank pages for me with the current calculator output.) Bret Hi, Bob.

I have tried to limit the page to "1 of 1" but it still prints 3 extra. Great service to everyone. I have used your calculator for over 10 years. Bob Hi Bret,

When I print an amortization it always adds 3 additional pages of blank sheets. I have tried to limit the page to “1 of 1″ but it still prints 3 extra.

Great service to everyone. I have used your calculator for over 10 years.

Things look OK to me on the browsers that I use, but I will look into it. What browser and operating system are you using? Is it only the print function that's not working properly? or does the schedule not display on the screen at all, either? Hi, David.

I'm guessing that the problem has to do with you typing in commas or other non-numeric characters. To enter $361,400.00 into a field of the calculator, type it as '361400.00' (without the quotes).

When the principal amount is $361,400.00, for instance, the calculator suddenly turns it into $361. Is there something I can do to rectify this? I've tried to use other online calculators, but they seem to all be set up for monthly payments only. Thanks for any help you can provide!

The calculator is behaving as it has been designed: the calculator looks for blank (or zero) fields to figure out what to calculate. So when you change a value in one of the fields, you need to blank out (or set to 0) the field that you wish to be re-calculated using the new values. By leaving only the Balloon Payment field blank, the calculator assumed that this is the value you wanted to calculate. Bret Hi, Earl.
