How do you figure amortization by hand, without the help of a mortgage calculator?

We Answered:

There is a formula, but I don't remember what it is. But, if you can get that loan at that interest rate over 30 years, TAKE IT! That is a great deal.

Online Mortgage Payment Calculator?

We Answered:

Try bankrate.com. You can play around with in adding extra payments, interest rates, and terms. I can't imagine a $200 mortgage anywhere in the US.

Can you help with Mortgage Calculator in Java?

We Answered:

There was a lot wrong with this. You had duplicate main methods, you tried to import while making a variable declaration (which would be a handy feature I suppose, but is invalid in Java), and forgot to extend the JFrame class and implement ActionListener. I fixed these and some other issues so that it would compile. Getting the logic to work is up to you though.
