Please let me know if the calculator does not perform the calculation as you expect.

I do not have an archived version of the calculator. However, I cannot duplicate the problem that you have described. The calculator does the right thing given the input fields you provided. I'm taking a wild guess, but maybe there's a residual value being passed along from your browser. You might try shutting down the browser and starting up a fresh copy of it and try again. If you continue to experience this problem, please write back with some more information about your browser and operating system. Bret Hi, Jeff. I do not have an archived version of the calculator.

The updated version gives me some unexpected responses. I need to be able to calculate the annual interest rate. So, I put 40000 as the principal, 12 payments per year, 144 regular payments, and 400 as the payment amount. I leave balloon payment and annual interest rate blank. The calculator changes the regular payments to 100 and sets the annual interest rate at 0. Help please! Hi Bret,

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.

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.
