This is a calculator you may never need. I created it because I wanted to see what would happen if you got a loan with a fixed principal payment instead of the normal loan that has a fixed (principal + interest) payment. So, here it is...

Other uses for this calculator:

INTEREST ONLY CALCULATOR Simply enter 0 for the Monthly Payment (Principal Only), fill in ALL of the other fields and press View Amortization Schedule.

PRINCIPAL ONLY CALCULATOR Simply enter 0 for the Interest Rate, fill in 2 of the other fields and press the button under the field for which you'd like to calculate. Select the date the first payment is due and press View Amortization Schedule.
